I’m so grateful for this video you have no idea. I watched you turn A/C off and fan on on the thermostat. I let the fan run for 5.5 hrs checking to see how much water was running out of the a/c drain pipe until it was just a drip. It was a miracle, I swear I came inside and turned a/c back on and the a/c blew ice cold like a new unit. I suffered this entire past week in the Florida extreme heat until I found your video today. My a/c guy wanted to charge me extra weekend rate to come out today. I’m glad I held off. I saved myself hundreds of dollars by watching your video. Please make a short so that more homeowners can watch your tips. Thank you so much from the bottom of my nurse heart. My kitty cats thank you too. We are enjoying our cold air conditioned home tonight. 🆒😁💯👍🏻
Mr. DIY: The best way to clean the coils is to spray the foam from the opposite side and let the foam work its way in; do not use any kind of brush because you just push some of the dirt into it; You may have to do it again in a year or two. I was in the business for 60 years and like to help others do the best they can. Thank you.
Great video with fairly simple instructions for average DIY homeowners. If I may add a few notes to further help your audience: 1- Always were a long rubber or latex gloves when applying these coil cleaner sprays. I did the same mistake and ended up with very bad rash on my skin that lasted 3-4 weeks. Also do not forget the goggles, these chemicals will eat right through your cornea and can make you blind. (Always rinse all your T-shirt and pants with plenty of water before adding them to your family laundry load.) 2- Always remove the filter from the bottom and drop several old towels at the bottom side of the indoor coil to soak up the water and chemicals. This simplifies the clean up process. 3- Buy a simple pump up water sprayer ($5 to $10) from the gardening section of super stores and apply some warm water to the fins and allow 5 minutes to soak before applying the coil cleaner. You get a lot more effective cleaning at the start of the process. 4- Start spraying the coil from below, you may use soft paint brush to slowly loosen up the dirt with each spray session. Do not forget to add cleaner to the top of the coil as well or you are going to push the dirt deeper inside the coil. Let the gravity do the work. 5- Make sure you wait for 15 minutes for each spraying session and if it is drying out too quickly, keep the coil fins sprayed with light amount of warm water to make the chemical reactions going. A coil as dirty as the one shown in this video will need at least 4 set of spray and rinse offs. 4 x 15 minutes + rinse off time. 6- At the end, rinse the coil with plenty of warm water using the pressurized hand pump from the top side and most of the run off water should go right into your condensate pump if you do not over spray and allow the run offs get into the sides of the coil. Take your time. 7- If you've done things properly, the towels still will be relatively wet, but this is normal. You must remove the towels carefully without damaging the coil fins and use a wet/dry shopvac to further clean up any internal dust or moisture. (Change your filters every 3 months for good air quality. Frankly, it will cost you a lot more to sweep your air ducts if you cut corners on frequently changed filters.) 8- This entire coil cleaning process may take you 30-60 minutes (sometime more if you use the shopvac to clean the blower fan, etc. ) BTW: There are different types of coil cleaners. The ones that foam and the ones that do not foam and claim to be self rinsing, so you may spray on and let it run and the condensation will clean it up. But note that almost all of these cleaners are caustic, and they will burn your skin, so wear gloves and goggles. (Dermatologist charge $500 or more and eye surgery is well above $10,000) Hope these are helpful notes.
Thank you!!! That was very helpful. My coils are completely frozen and until I watched this video had no idea what the problem was. So I reached out to a very popular HVAC company. They sent out a tech. this morning and he showed me the frozen coil and told me several reasons why it could be happening and quoted me $ 400 to just find a leak if the freon is actually leaking and then to fix the leak and fill it with freon $ 3800!!!! So I decided to pass up on his recommendations and turned to my trusted TH-cam and low and behold I landed on your page. Thank you!!! You have motivated me enough to do this on my own and if it is the freon then I will deal with it using a professional. Thank you again!!!
I feared the worst. Was gonna call my guy and figured my HVAC unit had taken a dump. Watched this video- bought the spray- cleaned the unit. Didn’t help. Did it again (since I know the unit hasn’t been cleaned in the 8 years I’ve lived here)- waited overnight, and the unit works like new. Hit 95 today and didn’t even know it! Thanks so much
Man, I just bought my fixer-upper this winter and recently started using the AC. I walked out my of house this morning, saw the ice on my pipes and freaked out. Thankfully I found this video before calling my repair man! NEW PROJECT!!!
I work in this field over 30 yrs and I think u did an excellent job,,,,,I would do it the same way,,,,,my only advice is get a better filter White one is and will be better,,,,u have a heat pump reverse cycle by the way,,,,u can defrost it in 5 min,,,by set the heat,,,,,only advice to u but u act as a professional urself welcome to our field,,,
Great video.... TY for sharing. My problem was a little different. On my honeywell thermostat, someone had changed the FAN setting to "Circulate", rather than AUTO. Ofcourse, when the compressor would turn on, the blower motor wouldn't... and that froze up my condensor unit. Posting as it may help someone.
Saved me money! There was a bunch of gunk on the underside of the evaporator and after a quick trip to Home Depot and about 1/2 hour of cleaning, I’m in a nice air conditioned home.
you probably dont care but does anybody know a tool to log back into an Instagram account..? I was dumb forgot the password. I love any tricks you can give me.
@Yusuf Baker i really appreciate your reply. I got to the site thru google and Im trying it out now. Seems to take a while so I will reply here later when my account password hopefully is recovered.
I did this 2 days ago. Went to ace hardware, bought some stuff for the coils and works like a new ac again. I cleaned it from top to bottom and took 2 hours. Proud of myself bc somebody said i needed a new ac unit. They just wanted 5 grand.
Excellent video! I just went through this a couple days ago. In my case the indoor blower was not running. Replaced the run cap and waited for the lines thaw and issue with frozen lines went away. I also cleaned the coil outside with same product. My had years of dirt build up and once clean my cooling improved. The cap vendor I used was Amrad. They are pricey but last longer than the Chinese made. Keep sharing DIY projects.
Thank you…. This video was very helpful…. We followed each step and our AC is back to normal…. Thank you so much for the step by step instructions and for saving us money 🙏🏾👏🏾
Best advice I've seen in another video is that when the air handler coil is cleaned, doing the exterior unit's condenser radiator should be done. There's a reason the instructions indicate doing it 2X a year. As for the low on freon, that means there is a leak & the professional will be needed at that point, unless you know what you're doing with HVAC systems.
I’ve always known that to be called the A frame….i clean the one on my set up every spring…for some reason it gets pretty dirty but I live by a ton of cottonwood trees on the edge of town…that cotton floaty stuff gets everywhere including the vehicles air breather…I just try to get the thing to dry down completely if it’s already been frozen over and damp now…if it’s dry then east to clean….get the layer of cottonwood cotton to start in one corner and pull it off….and then carefully clean the rest of it with a shop vac and attachment ….im surprised so many home owners don’t know about this sort of thing and neglect their heating and cooling systems like they do….mist people have never even vacuumed out their duct work either….the crap that builds up in the duct work alone is surprising lol
Nice video!! My AC just froze when we got back from vacation. Fan is on and will be on all night and we’ll check on it in the morning. We’ll try coil cleaner and replace filter and hopefully no more freezing. Two year old house and already frozen. 🤔🤔🤔
Great video! Really helped give me a look inside and a boost of confidence I could do it myself. You are friendly, easy to understand, stay on task and best of all were engaging. My favorite video of all the ones I watched!
Dude.. you just saved me a visit and some $. Even with seasonal filter replacements, I didn't think this would be the issue. But took the furnace apart and sure enough there was a 1/8th of an inch of buildup. Peeled it off in huge sheets. Got it cleaned and now no more freezing. Thank you.
Thanks, great video! Most times it's the filter. Don't go with the fancy 2200 filters, the 1000 works better as it moves the air better preventing this build up.
It's funny looking at the dates of the comments, some from last summer some from the last couple of days. Another pro tip, dont buy a home warranty from HMS home warranty. Home warrantys are for wealthy people who can afford to flush money down the drain. D.I.Y. Great video bro!
Just so you know, You have a heat pump. You can tell by the reversing valve located inside of the outdoor unit. Another way you could have defrosted your suction line or "pipe" is by switching the system into heat. The system would have then "reversed" bringing the heat collected by your outdoor unit, bringing it inside to defrost your indoor coil and suction line... Although you fixed your unit. My guess is that your system is low on refrigerant. Im guessing your unit takes R-22. The loss of refrigerant in the system, will lessen the pressure. Refrigerant is designed to be a specific temp at a specific pressure. The lower the pressure in the system, the lower the temperature. My guess is the pressure in your system reached the point where it was so low, that the temperature dropped to near freezing causing the frost buildup. For another tip, I would recommend going to your local hardware store and getting a standard pleated air filter. That would prevent your indoor coil from getting as dirty as it was again!
Fantastic video brother. New subscriber!! You did WAAAY better than the pro channels. Thank you. First time homeowner learning the hard way how to maintain everything.....😂
Thank you for the video. I didn't even think about the coil clean spray until you mentioned it. Thank you for that. Also you mentioned using a soft brush I agree with that, but I wanted to point out that they make a tool to straighten out any bent fins. You may already know this but just in case I thought I'd let you know. Thanks again for this video really appreciate it.
I'm a hvac tech and when your pipes freeze its cause of airflow problems a leak in the system or a restriction either in the filter dryer or in the txv. If your pipes are frozen I would let it thaw naturally if you decide to run the fan or heat, the ice will melt faster meaning that water can get into the electrical and can damage the system.
Another even quicker pre-test to see if the evap is plugged or fan not running is hold your hand near the AC outlet vents in the house and you should easily be able to feel flow..it should flow like it did while it was working properly before the problem started, but no (or severely restricted) flow is a definite indicator that something is amiss in the evaporator (inside) box, typically called an air handler. If the problem persists after you have replaced the filter and cleaned the coil it is time to call an HVAC tech in to fix the problem, unless you the necessary skills and tools to diagnose the problem properly and the proper tools to evacuate, fix, charge, and test it...capabilities far beyond most DIY level folks, but not all of them. I have fixed several automotive, a couple of residential, and am currently about to start my first attempt at a sick fridge. It also helps to have a good tech to consult occasionally even when you know a goodly amount. There truly IS no substitute for tons of experience...although I have seen a few techs who HAVE had tons, and were clueless idiots, as well. One guy came in on a rental property of mine, which was low charge I determined later, LEVELED the damned thermostat, and left. Needless to say, I didn't pay him the $60 he tried to charge me, as his "fix" did NOTHING to remedy the problem. That's what I get for going on vacation and having a renter set up a service call, I guess. One other thing you might add is make sure the inside blower motor is running when the unit is cooling, as you could hear it was on yours.
I’m trying this tomorrow morning. First time home owner here and I have no idea what I’m doing half the time. I have had water dripping out of my furnace and the pipes freezing so I hope this fixes it
WIth a foaming spray such as web's coil cleaner, it does not specify which side to spray it at. Logically, it would make more sense to spray it in from the clean side, as the foam expands and you want to push the material back out the direction it came in from, right? You would see where your rough spots are where foam coil cleaner does not come through. Like others commenting below, spraying the coils with warm water and letting it soak for a few minutes before allows the chemicals to do their job easier. Thanks for the video. I cleaned my A frame evaporator coil myself, had HVAC come by and add 2.5 lbs of R-22, and repaired my condenser fan electric motor myself when it locked up two days later.
Awesome. Great easy tutorial. I completely agree with your points on trying things for yourself via research etc prior to last resort and calling a professional. Save some money if your able to do it all on your own. Glad you're able to get your AC running smoothly, hot days always suck
The freezing up starts at the indoor coil and works it’s way to the outside unit. I don’t know if you did it but you should of let the foam expand and lift the debris from between the coil fins and then rinsed the cleaner as suggested with water.
Just put your hose on the top of the coil that he showed first (outlet side) Don't use water pressure too high because, again, you don't want to bend or break any fins on the coil. Also, don't let the water running off get into your blower or short any electrical devices. Dry thoroughly before restoring power to the unit.
Your comment is probably one of the most rewarding comments I've ever received here on youtube. I hope you and your family remain cool in this summer heat.
If you need refrigerant "Freon" you probably have a leak on the Schrader valve on the outside condenser unit. Can check by removing the cap and check with soapy water for bubbles. Looks a little bit like the valve stem of a car tire. There should be two Schrader and two King pins on the outside bottom of the unit.
Hi, there! This is Jermey McGuire. Your evaporator coil was dirty you cleaned the coil, you forgot the condenser coil on your air conditioner.” You must keep the conditioner coil clean, because air sucks into to the condenser coil. And the fan blows the hot air from the top of your air conditioner.” When the condenser coil gets clogged up, you’ll have higher head pressures.” And can trip the high pressure switch, I had that happen to me. I had a 15 year old Lennox 5 ton air conditioner that cooled the upstairs at my house. The high pressures switch tripped I had no cooling upstairs.” This was back in July 2022 then I had another break down last July 2023, the blower motor died.” I finally got the motor replaced then it went out again in the fall, I got that air conditioner replaced and I got my downstairs air conditioner replaced back in April. It gets so hot in South, Texas.” You definitely need air conditioning!! So when you have a dirty conditioner coil.” Your air conditioner ail freeze up. I hope this was helpful BTW!! Like you said 1st thing check your filter. And another thing you should check is the drain line, because the drain line will buildup sludge and algae.” So you need to pour bleach from your a/c drain line. And you Mr air conditioner will freeze up if you’re low on refrigerant or have a refrigerant leak.” So you’ll need to get a licensed HVAC technician to inspect the unit for leaks.
Many times you can not clean an Evaporator Coil without removing it - the underside is inaccessible. Also, the Evaporator Coil rarely gets dirty because it's only exposed to well filtered air (assuming you use quality air filters and change them regularly).
Every minute that a compressor runs under those " frozen " conditions it will degrade until it fails. When you see frost on refrigerant suction lines it means that you are pumping liquid refrigerant to the compressor. An air conditioning compressor is a " vapor pump " and does not want to see liquid refrigerant.
I explained all this to the ac guy. Frost in the SAME place after an hour. He did hours of tests and “ no leak”. Fills and waters leaking. “ ohhh drains clogged”... Run run run..800 later. And an hour after he leaves, BOOM ICE. Same spots as this vid. I am so pissed. I just wanted a diagnosis. If I would’ve known the problem would’ve persisted I would’ve never of had it filled only to be flushed down the toilet. Being female rules! Get ripped because everyone thinks I’m going to be a moron. So now I have to resort to this crap. Least it’s hope. And $7.... So whether it works or not I’m thankful for videos like this
Also plan to foam clean the evaporator coils as a routine during the cooling season not at end of season maintenance ( filter prep for next year etc) . You need the AC unit working on a humid day to produce enough water to rinse the coils off sufficiently .
00:25 AGREED!! LOL that's why I'm here watching this! My Godmother literally has nicknamed me Maguyver because of I like to figure out and fix things myself. Google and TH-cam has been a game hanger in this world and for us that like to tinker to save money..!
Good video. I probably would have sprayed the top side too and let the cleaner work through the cooling fins. Maybe even rinse (distilled water spray bottle) if able to devise a way to catch the drips.
Nice job man. Not sure if you did or not but try spraying the coil with a water hose from bottom to top and top to bottom, really get that dirt out after you’ve sprayed your coil cleaner. Obviously try and avoid wetting any of your ductwork, electrical
It look like you had a filter in the rack and one behind that grill in the hallway. Unless the had their own designated duct you shouldn't have two filters in the same path. Double filteration can cause pour airflow across that coil too. Other then that good job.
I replace the A coil , outside unit works fine. After 3 days it freezes up then I guess pressure loss of freon. Had a 2nd tech, found bad welds, fixed welds, pressure test, recharge with freon. Same issue after 3 days. The A/C original unit was installed in 1998. I been here since 2008, only ran the A/C unit for a few days. Been running window units since 2008. Need help
I'm an hvac professional. It begins freezing on the inside...by the time you see ice outside the entire inside unit will be frozen and you will barely have flow out of your supply vents if any.
Multiple issues can cause that or a combination. Most common lack of airflow (dirty filter or evap coil) Failed electrical components either outdoor fan motor/indoor motor. Lack of refridgerant Restricted metering device. Homeowners typically can fix the lack of airflow issues generally insuring filters are clean or cleaning their indoor coil as the above video showers if easily accessible. Someone trained in electrical can maybe repair their fan motors if they can find the parts and have tools to do so...electricity does not forgive so no recommended for just anybody Lack of freon can only be fixed by EPA certified individual such as an AC tech
If you have a restriction In the metering device or copper that can only be repaired by an EPA certified individual. Non certified personnel working or doing anything with refridgerant is highly against the law
Good video! I just had the same problem for the second warm start of summer in a row, I fixed the fan relay last year this year the condenser is freezing up didn't realize you had to clean that like you do with the outside unit 👍🏻
@@spoc after cleaning the ensign unit and replacing the wet filter, I had a local HVAC shop come by and they even complimented me on cleaning the condenser first, they said I would have had to pay them an extra $100 to do that first. They tested the system and said that I was low on coolant. I've had ice Cold air since then :-) Thanks
@@SAABguyMD phillip, thank you so much for the compliment. Comments like yours is what it's all about. Sorry it was something more complicated but glad I could save you a few bucks.
More than half of my calls I run are issues that have to do with the refrigerant itself, or the compressor being bad or even the metering device is plugged. Just maintain your equipment by cleaning it all off and then if you have issues after that, its more than likely its a fault YOU cannot fix as a homeowner.
@@justinpoole8227 at what point did I degrade? I simply pointed out the truth saying its my profession? Hell I encourage people to try and fix their own stuff so then I dont have to work lol
So I have a question it might sound stupid, what if you remove all the frost form the lines and then run the heat on high ?? Wouldn’t that help solve the problem as well ?
Had a tech come out and "fixed it." Only worked for 2 days. Followed the steps in the video and now my AC works like new again!
🙋🏾♂️what did the tech do and how much did he charge for the visit?🤷🏾♂️

It's funny looking at the dates of the comments, some from last summer some from the last couple of days. Another pro tip, dont buy a home warranty from HMS home warranty. Home warrantys are for wealthy people who can afford to flush money down the drain. D.I.Y. Great video bro!
Just so you know, You have a heat pump. You can tell by the reversing valve located inside of the outdoor unit. Another way you could have defrosted your suction line or "pipe" is by switching the system into heat. The system would have then "reversed" bringing the heat collected by your outdoor unit, bringing it inside to defrost your indoor coil and suction line...
Although you fixed your unit. My guess is that your system is low on refrigerant. Im guessing your unit takes R-22. The loss of refrigerant in the system, will lessen the pressure. Refrigerant is designed to be a specific temp at a specific pressure. The lower the pressure in the system, the lower the temperature. My guess is the pressure in your system reached the point where it was so low, that the temperature dropped to near freezing causing the frost buildup.
For another tip, I would recommend going to your local hardware store and getting a standard pleated air filter. That would prevent your indoor coil from getting as dirty as it was again!
Thank you!! You save me $120 just for the technician.
Thanks for the info and video.
Fantastic video brother. New subscriber!! You did WAAAY better than the pro channels. Thank you. First time homeowner learning the hard way how to maintain everything.....😂
As someone that Knows whats over my pay grade, thanks for the insight on a current issue.
I would still put the gauges on it and measure the preasure and the sub cooling. Low refrigerant will freeze the coils to Good job
Thank you for the video. I didn't even think about the coil clean spray until you mentioned it. Thank you for that. Also you mentioned using a soft brush I agree with that, but I wanted to point out that they make a tool to straighten out any bent fins. You may already know this but just in case I thought I'd let you know. Thanks again for this video really appreciate it.
I'm a hvac tech and when your pipes freeze its cause of airflow problems a leak in the system or a restriction either in the filter dryer or in the txv. If your pipes are frozen I would let it thaw naturally if you decide to run the fan or heat, the ice will melt faster meaning that water can get into the electrical and can damage the system.
Another even quicker pre-test to see if the evap is plugged or fan not running is hold your hand near the AC outlet vents in the house and you should easily be able to feel flow..it should flow like it did while it was working properly before the problem started, but no (or severely restricted) flow is a definite indicator that something is amiss in the evaporator (inside) box, typically called an air handler. If the problem persists after you have replaced the filter and cleaned the coil it is time to call an HVAC tech in to fix the problem, unless you the necessary skills and tools to diagnose the problem properly and the proper tools to evacuate, fix, charge, and test it...capabilities far beyond most DIY level folks, but not all of them. I have fixed several automotive, a couple of residential, and am currently about to start my first attempt at a sick fridge. It also helps to have a good tech to consult occasionally even when you know a goodly amount. There truly IS no substitute for tons of experience...although I have seen a few techs who HAVE had tons, and were clueless idiots, as well. One guy came in on a rental property of mine, which was low charge I determined later, LEVELED the damned thermostat, and left. Needless to say, I didn't pay him the $60 he tried to charge me, as his "fix" did NOTHING to remedy the problem. That's what I get for going on vacation and having a renter set up a service call, I guess.
One other thing you might add is make sure the inside blower motor is running when the unit is cooling, as you could hear it was on yours.
Thank you for posting this video. I'm going to get some of that coil cleaner , before I have any issues with my AC.
I’m trying this tomorrow morning. First time home owner here and I have no idea what I’m doing half the time. I have had water dripping out of my furnace and the pipes freezing so I hope this fixes it
WIth a foaming spray such as web's coil cleaner, it does not specify which side to spray it at. Logically, it would make more sense to spray it in from the clean side, as the foam expands and you want to push the material back out the direction it came in from, right? You would see where your rough spots are where foam coil cleaner does not come through. Like others commenting below, spraying the coils with warm water and letting it soak for a few minutes before allows the chemicals to do their job easier.
Thanks for the video. I cleaned my A frame evaporator coil myself, had HVAC come by and add 2.5 lbs of R-22, and repaired my condenser fan electric motor myself when it locked up two days later.
Kudos👏🏽. Make sure to do the same to your outdoor coils as well. Mine where filthy. Now I need to check the inside😭
Awesome. Great easy tutorial. I completely agree with your points on trying things for yourself via research etc prior to last resort and calling a professional. Save some money if your able to do it all on your own. Glad you're able to get your AC running smoothly, hot days always suck
I’m gonna try this tomorrow... actually I can’t wait lol it’s sooo hot in here 😩😂
Having same issues. Gonna try that in the morning. Thanks man!
Awesome video. Coils are filthy on mine. Thanks for video
The freezing up starts at the indoor coil and works it’s way to the outside unit. I don’t know if you did it but you should of let the foam expand and lift the debris from between the coil fins and then rinsed the cleaner as suggested with water.
How do you rinse with water if the coil is inside and you can't get it out?
Just put your hose on the top of the coil that he showed first (outlet side) Don't use water pressure too high because, again, you don't want to bend or break any fins on the coil. Also, don't let the water running off get into your blower or short any electrical devices. Dry thoroughly before restoring power to the unit.
That cleaner is a rinse free formula. If your using it on a condensation coil it rinses itself
I just finished your troubleshooting tips as we speak and me along with my family want to thank you and have a great summer
Your comment is probably one of the most rewarding comments I've ever received here on youtube. I hope you and your family remain cool in this summer heat.
You too bro and this was the most helpful video i ever watched Lol
What was your problem?
If you need refrigerant "Freon" you probably have a leak on the Schrader valve on the outside condenser unit. Can check by removing the cap and check with soapy water for bubbles. Looks a little bit like the valve stem of a car tire. There should be two Schrader and two King pins on the outside bottom of the unit.
I super duper enjoyed it and if I could like it a million times I would’ve 🥰🥰🥰🥰🥰🥰, u just saved me money 💰. Thanks 🙏🏿
Great to hear!
Awesome video.
Hi, there! This is Jermey McGuire. Your evaporator coil was dirty you cleaned the coil, you forgot the condenser coil on your air conditioner.”
You must keep the conditioner coil clean,
because air sucks into to the condenser coil.
And the fan blows the hot air from the top of your air conditioner.”
When the condenser coil gets clogged up, you’ll have higher head pressures.”
And can trip the high pressure switch, I had that happen to me.
I had a 15 year old Lennox 5 ton air conditioner that cooled the upstairs at my house. The high pressures switch tripped I had no cooling upstairs.”
This was back in July 2022 then I had another break down last July 2023, the blower motor died.”
I finally got the motor replaced then it went out again in the fall,
I got that air conditioner replaced and I got my downstairs air conditioner replaced back in April. It gets so hot in South, Texas.”
You definitely need air conditioning!!
So when you have a dirty conditioner coil.”
Your air conditioner ail freeze up. I hope this was helpful BTW!!
Like you said 1st thing check your filter. And another thing you should check is the drain line, because the drain line will buildup sludge and algae.”
So you need to pour bleach from your a/c drain line. And you Mr air conditioner will freeze up if you’re low on refrigerant or have a refrigerant leak.”
So you’ll need to get a licensed HVAC technician to inspect the unit for leaks.
You are doing the Lord’s work
Many times you can not clean an Evaporator Coil without removing it - the underside is inaccessible. Also, the Evaporator Coil rarely gets dirty because it's only exposed to well filtered air (assuming you use quality air filters and change them regularly).
Great video! This helped me so much. I'm so thankful for my fellow YT DIYers!!!!!👏👏👏💪💪💪
Well done sir. I'll get that coil cleaner and let you know the results.
very informative thanx.
Thanks u teach a man to fish he feeds a village *( in this case he can cool his home for his family )👌🏾👍🏾💯
Nice. I’ll do this today for my A/C. Thank you.
Yessss. I dont have to call the shady noncertified ac guy!
Thank you so much for your helping very helpful ideas. Very clear and good instructions for DIY. Thank you so much Sir.
Thank you sir. I get the same problem.
Good job man, only ac techs could leave bad comments, thank you for sharing
Great job---I could easily follow
Every minute that a compressor runs under those " frozen " conditions it will degrade until it fails. When you see frost on refrigerant suction lines it means that you are pumping liquid refrigerant to the compressor. An air conditioning compressor is a " vapor pump " and does not want to see liquid refrigerant.
Thank you
I explained all this to the ac guy. Frost in the SAME place after an hour. He did hours of tests and “ no leak”. Fills and waters leaking. “ ohhh drains clogged”...
Run run run..800 later. And an hour after he leaves, BOOM ICE. Same spots as this vid.
I am so pissed. I just wanted a diagnosis. If I would’ve known the problem would’ve persisted I would’ve never of had it filled only to be flushed down the toilet.
Being female rules! Get ripped because everyone thinks I’m going to be a moron. So now I have to resort to this crap. Least it’s hope. And $7....
So whether it works or not I’m thankful for videos like this
So did it work?
Also plan to foam clean the evaporator coils as a routine during the cooling season not at end of season maintenance ( filter prep for next year etc) . You need the AC unit working on a humid day to produce enough water to rinse the coils off sufficiently .
00:25 AGREED!! LOL that's why I'm here watching this! My Godmother literally has nicknamed me Maguyver because of I like to figure out and fix things myself. Google and TH-cam has been a game hanger in this world and for us that like to tinker to save money..!
Yup that worked, you saved me so much money. THANK YOU
Good video. I probably would have sprayed the top side too and let the cleaner work through the cooling fins. Maybe even rinse (distilled water spray bottle) if able to devise a way to catch the drips.
Nice job man. Not sure if you did or not but try spraying the coil with a water hose from bottom to top and top to bottom, really get that dirt out after you’ve sprayed your coil cleaner. Obviously try and avoid wetting any of your ductwork, electrical
great tutorial video tnx champ
Thanks!
Wonderful video, I’m going to go try the same fix. Here’s hoping 🤞🏻
What was your outcome? Did it help you?
Excellent video. Thank you for your help. I really appreciate your willingness to help others and your humbleness. Thank you.
Thanks for posting! I solved the problem within half a day.
Thanks great to hear. Glad to have helped!
Just letting you know if you use better air filters , pleated air filters to be exact . Your evap coil won’t get dirty
Merv13
Fantastic informative video sir thank you 👍👍👍👍👍
It look like you had a filter in the rack and one behind that grill in the hallway. Unless the had their own designated duct you shouldn't have two filters in the same path. Double filteration can cause pour airflow across that coil too. Other then that good job.
good video amigo
I replace the A coil , outside unit works fine. After 3 days it freezes up then I guess pressure loss of freon.
Had a 2nd tech, found bad welds, fixed welds, pressure test, recharge with freon. Same issue after 3 days.
The A/C original unit was installed in 1998. I been here since 2008, only ran the A/C unit for a few days.
Been running window units since 2008. Need help
I learned something new. Thanks.
Right on... much love brother
Good job! Thank you.
I'm an hvac professional. It begins freezing on the inside...by the time you see ice outside the entire inside unit will be frozen and you will barely have flow out of your supply vents if any.
Thanks for the insight, Trevor. I appreciate your comment.
If that is the case how do you fix that?
Multiple issues can cause that or a combination.
Most common lack of airflow (dirty filter or evap coil)
Failed electrical components either outdoor fan motor/indoor motor.
Lack of refridgerant
Restricted metering device.
Homeowners typically can fix the lack of airflow issues generally insuring filters are clean or cleaning their indoor coil as the above video showers if easily accessible.
Someone trained in electrical can maybe repair their fan motors if they can find the parts and have tools to do so...electricity does not forgive so no recommended for just anybody
Lack of freon can only be fixed by EPA certified individual such as an AC tech
If you have a restriction In the metering device or copper that can only be repaired by an EPA certified individual. Non certified personnel working or doing anything with refridgerant is highly against the law
Trevor HVAC Life not if you’re the homeowner
Good video! I just had the same problem for the second warm start of summer in a row, I fixed the fan relay last year this year the condenser is freezing up didn't realize you had to clean that like you do with the outside unit 👍🏻
Thanks for the comment. Best of luck with your unit and may you forever have ice cold air :D
@@spoc after cleaning the ensign unit and replacing the wet filter, I had a local HVAC shop come by and they even complimented me on cleaning the condenser first, they said I would have had to pay them an extra $100 to do that first. They tested the system and said that I was low on coolant. I've had ice Cold air since then :-) Thanks
@@SAABguyMD phillip, thank you so much for the compliment. Comments like yours is what it's all about. Sorry it was something more complicated but glad I could save you a few bucks.
I appreciate your video clean cut simple, great job
Excellent video for DIY.
You saved me hundreds!!! Thank you soooo much!!!
The spray foam should be applied from the back side of the coil for best results!
great info.
Thank you!! We are trying it now!
More than half of my calls I run are issues that have to do with the refrigerant itself, or the compressor being bad or even the metering device is plugged. Just maintain your equipment by cleaning it all off and then if you have issues after that, its more than likely its a fault YOU cannot fix as a homeowner.
This guys taking you out of business huh?
@@justinpoole8227 at what point did I degrade? I simply pointed out the truth saying its my profession? Hell I encourage people to try and fix their own stuff so then I dont have to work lol
Great job, great video keep up with the good diy stuff.
I'm like you, I love to do things myself until screw it, then I call the pro 😂😂😂
So I have a question it might sound stupid, what if you remove all the frost form the lines and then run the heat on high ?? Wouldn’t that help solve the problem as well ?
I'm having the same issue. Hope it is just a filter for me. Open the coil compartment maybe too dangerous for me. I'm afraid of being electrocuted.
Solid vid 👍🏽 You saved me $390
Awesome vid brother. Hope this is my issue. Easy cheap fix. Thanks.
Good luck!
