Glad you enjoyed it!
Thank you, heard rattling this morning and expected the worse. Thanks to video realized it was an easy fix
Thanks for making this video! My AC was shaking violently this morning after a snowy night. I saw your video and quickly went out to clear the ice from the bolts. Problem solved!
Great job!
Hey bro I'm just starting my hvac career and I really enjoy watching your videos, they help me out a lot, thanks for taking the time👍
That is great to hear! Thanks for the Comment!
excellent videos. I gather since your down south that you will not be doing similar videos for furnace trouble shooting ? your videos have been a huge help during my first year of refrigeration. thank you
I absolutely will do furnace videos. I will be switching my teaching attention to furnaces during the fall and throughout the winter! I am located at the southern tip of New Jersey. Great to hear!
excellent video thank you for sharing!!!!!!
Thank you!
Hey thanks buddy you save me a lot of money I appreciate your help and video thanks and god bless you this new year
Thanks, you too!
Thanks for the video. It gave me a little piece of mind. I just had a Heil 2-ton put in my 1190 square foot house and it makes twice as much noise as my old 18 year old grand aire compressor that was still kicking :-) so I was concerned with the noise and wondering if the unit was defective or not. Or they were bad bearings. Thank you :-)
one question.. I went to turn the temperature down one notch and it seems that when I went to do it the outside compressor had just turned off but the inside unit was still running. When I did this it appeared to send a surge to the compressor bad enough to shut it down. It sounded like the compressor was going to take off for about 10 seconds or more. Is this normal? I asked the company to come out and check everything and they put a surge protector on the inside unit and said everything checked out okay.
Thank you for this video!
Thanks Richi!
Mine started making this same noise first startup after winter and ended up actually being the center plate area bolts that holds the fan motor. Tightened those down and it's a bit quieter now. Hopefully will last.
Thanks for the tip
So is this an example of a normal sounding A/C? I HATE the drone sound on mine but I don’t know if it’s normal or not. For some reason it is next to my bedroom. Can those units be moved?
What sound are you talking about with the scrolls? Do you have an example? What does it sound like?
Thank you you solve my problem thank you thank you
Thanks Abraham!
Hello AC service tech, could you please provide some more information about the loud noise made by the scroll compressors on start up and shut down? I was reading some literature about compressors and it suggested that its because of the mount type ( rigid or spring mount). I am a third year apprentice from Canada. Thanks already for your valuable input.
I would like to know that too, because my new home outside AC unit is next to the bedrooms first floor and second floor. That noise makes those two rooms too loud to sleep in.
Please excuse thje caps . HI THERE FAC FOLKS ----WELL YOU RE-NEWED MY FAITH IN HONEST A. C. WORKERS . I GOT AN AUTO MECHANICS LICENSE 35 YEARS AGO & WORKED MANY OTHER JOBS instead for about 40 years . Almost took A.C. school . However I do honest work in everything and it is great to spread the knowledge for prosperity & trust so DIFs can learn & pros can earn . THANKS for your vids . ED
I just had a new Trane XR 14 HVAC installed and I noticed that during startup the condenser makes a buzzing noise for about a minute. Sounds like it's coming from the compressor. Once it runs for a minute or two the noise goes way. I was told by the installation tech that it is normal. If that normal?
Having a problem with a unit, the condenser fan motor is getting hot and to me the the blades aren't spinning fast as they supposed to also the compressor turns on for a second and off and it's also hot, I already replaced the dual capacitor cause it was bad, the unit was installed about 2 years ago
I heard American standards are just loud in general? Mine is two years old when on too long it goes very loud then quiet like the refrigerant is off and only outside warm air blows in my nest goes up 2 degrees and then the unit kicks back on. Its doing it almost daily mostly when its hot out any ideas?
Any idea how to stop neighbors stupid condenser its below the bedroom wall i'm upstairs and the stupid thing resonates in the walls its so annoying. The compressor in it is so loud it can be easily heard when all 4 units are running at the same time. It says on the unit it was made in 2006
But what about when your outdoor heat pump stops its cycle and sounds like an 18 wheeler apply dry brakes? Something between canadian goose and a dying moose. Then it starts again almost immediately and then stops and sounds normal??
Hello what about smoke coming is normal in interv?
This what my AC is doing.
A new York compressor YCE42B22S nosiey running, buzzing almost electrical motor sound. I ordered a blanket. Not sure if that's normal.
I checked the screws on my unit All is tigh.
But i did place a gallon jug of water on it and it stopped making noise.
Might unscrew front cover and see if it stops
I recently mowing the lawn of a customer and found that the plastic shroud had disintegrated and that most of the pieces were laying inside the condenser unit, the piece that attached to the top of the unit was still intacted. I checked to see about getting a replacement one. No such luck, the unit was an older one. The AC service owner told me that he had seen people use chicken wire. I took zip ties and attached the chicken wire to the piece that was still whole and cut the wire to fit, bending the excess under the piece and then reattached it to the top of the unit.
When we pull old units out, we save the tops just for that reason since we are near the shore and the tops rot, thanks
Thought this would be helpful for others that follow your channel.
acservicetech hey i dropped something in my outdoor air conditioner. Any idea how to get it out?
Turn off the power, verify it is off, take the top condensor fan shroud off with the bolts, be careful with leaving the wiring attached so as to not damage the wires or conduit. Put it back and test it.
I'm just interested here, but are you using a laptop or phone to record the audio? Those types of devices typically have multiple enhancements or effects to cancel out background noise and only focus on voices.
This was an old video using a webcam and laptop. Check out some of the newest videos and let me know what you think.
What town in southern new jersey are you in? I live in the Wilmington, DE area
Nice, Middle Township in Cape May County NJ.
My AC doesn’t have that cage. After watching this I put 3 pavers over the center and it stopped making noise. The bolts are holding them off the unit and most of the vent is exposed. Do you think the pavers are a safe fix ?
My unit just recently become noisy on start up. A real racket but just briefly. Inside the house it sounds like a jet on take off.
Mine too. Did you figure out what was happening?
For some reason, with the AC unit my family has is on heat mode, the thick wiring going into the walls and ceilings throughout to the utility closet will make the walls and ceiling vibrate with a loud buzz and humming sound whenever the heating system is warming down the apartment. Also sorry for my awful grammar.
If wiring or breaker box is making a buzzing sound, you should have an electrician look at that
Well the thing is it only does that on heating mode, when it's on cooling mode for the summer, it's silent.
@@sethhorst6158 I have this problem currently. Did you find out the problem
@@talowmazmadden3206 I honestly wish I did, but me and the family I live with moved out of the apartment awhile ago.
You didn't EXPLAIN why scrolls make a loud noise when starting up.
Yeah, that's my problem. Forgot?
I mean, my AC makes noise when starting.
It doesn't matter why... They just do. It's too technical for the average person to understand.
@@dontblameme6328 wow what an arrogant thing to say... what makes you think everyone watching his videos is a no clue joe?...i apologize if that describes you also tho
This is the other noise you may hear. Scroll down on the page for video. I found it helpful
It's the coolant for heating or cooling running through the unit before it starts to heat or cool ur home. Does a buzzing for a minute before a loud hiss and starts runnjng
Fan blade imbalance. I glued a big rock to my top shroud. It's called an Inertial Vibration Dampener. Quieted right down.
Ha ha, nice!
I thought of doing that on mine bug would that cut down efficiency ?
@@timm4631 Nope. Looks silly though. 10lb Rock still there. 25 year old unit.
Is a sound compressed blanket worth it? Good in a hot location like Texas?
Yep.
How much is similar in style and put a little bit shorter and wider a little bigger I think, also It’s much older Or a little owner or so, and plus when it runs on start up it makes a loud humming noise and then the whole thing starts to shake the housing in the guard. I think it’s because one of the blades/blds off balance like maybe not as Think of a picture or so, and what made me just hombre itself that basically one in particular is more balanced, so that causes the whole thing a shank. First the moon and makes a really loud humming noise
mine just started making a squealing noise from the rotating fan?
Use garden hose washers
There you go!
Hello, one of my friends outside unit fan is making loud noise while running..condenser fan is running but sometimes it will make loud noise and run and run normal ..it keep doing in heat mode ..I could not figure it out..I change capacitor and still doing..please give me what I should be checking
Bawipeng Cin check the blade hub make sure it’s tight to the blade
Thank you
My ac makes the same noise
Im in a hotel and its making a loud noise and not cooling down
Normal? My neighbor has the same unit as I do, yet theirs does not make that awful grinding noise at shut-off as mine does. Wakes us up all through the night with each on and off cycle.
RHINOSAUR same happens to mine too idk if it’s a problem or just how it is
If someone can clarify? I'm thinking the noise does not nevessarily indicate that something is wrong although it can sound quite hideous lol..
I have a trane unit with a flat shroud. No screws on edges, but put foam under ends of one of the cross bars and stopped noise and vibrations completely.
QUESTION??? Last week my a.c line froze up. The maintenance man came to my apt and cleaned the coils. Changed filter and added Freon. After that half of the apt isn’t blowing air out the vents and the other half is hardly blowing. We live in a 1000 sq ft apt. Of course maintenance man says it shouldn’t get cooler than 78 because it’s summertime. But before this happened I had it at 72 all day and night. We live in Texas. Now it’s freezing at night only and started making loud humming noise. Temp never gets lower than 75. Maintenance man won’t help
Thats not good. It should be able to cool the building if sized correctly. I would hire a different tech if possible, thanks!
Thx
Mine make olot of nise and when i touch the top putting precion stop the noice
Thanks!
Thanks!
Temporary fix put a brick on top of the shroud.
Ha ha, that would do it!
when it kicks on makes a loud sound then stops ,and does it every time it kicks on
Am I the only one that likes this sound? I think it helps me sleep, it's good "white noise". :p
I thought the same thing, sounds like some "drone" music from some Oriental religion.
Mine is rather loud too now that this time of year its a bit colder, and I was concerned about it. I suppose everything is working fine though and there are no issues. Might as well enjoy the "white noise"! You're right!
why do I hear a rumbling noise in my house when my AC is on? And how do I fix it?
It may be the indoor unit vibrating or ducts vibrating. You could try to isolate that with rubber isolation pads, thanks
Our problem is that our hvac unit w o nt take braks--once the neighbor turn it on its own for hours and days without turn off once it reaches the temperature set. BUT THIS SUMMER THE UNIT WONT SHUT DOWN.EVER. VERY STRANGE AND.WE CAN'T FIGURE OUTVHOW IS THAT EVEN POSSIBLE (can't ask the neighbor cuz he is really ahresive and rude to everyone and don't want to be on his radar.
Great video. One possible area of noise is the fan motor itself through dry or worn bearings. I have oiled mine several times before eventually replacing one of the. Oil does the trick for days, weeks, sometimes years. Here's a video I made on that. th-cam.com/video/wSBr0PDCbzE/w-d-xo.html
Thanks, looking for a suggestion / response like this. Not all noises are created equally.
So what happens if the unit is making noise on start up?
That could be many things such as too much oil at the compressor or no superheat right after startup but the scroll makes more noise upon startup and shut off than the reciprocating but is quieter while running. Is the noise getting worse? You may want to call a tech out for that one to read pressures and amps, thanks!
If it's a goodman, there's nothing that can be done. The cheapness is built right in.
Ha ha. This one was a Payne, thanks
hahaha, I was figuring I may be wrong, but thought I'd try anyhow. But, yours is still a Payne (in the ass), I see. lol. I did see a goodman with a silencer added on (a brick), lately around here where I live. had to laugh because hackfreehvac points out the brick silencers on goodmans too. lmao...cant make the stuff up. Really crappy about the payne compressor being so loud, though. ive got an old skool keeprite. soooooo quiet. they really don't make em like they used to!
My bryant out door unit is that loud and doing the same thing
Thanks Joshua, yeah read the comments below for tips on what others are doing such as adding a piece of rubber between the grill and the shroud, thanks!
@@acservicetechchannel it's the loudest thing in my back yard louder then a lawnmower
I am here because my 410A compressor rattles or chatters on shut down. Guess it a scroll compressor.
Yes, scrolls can sometimes experience a rattle at shutdown. It's caused by high pressure refrigerant changing direction and stopping the rotating scrolls and spinning them backwards once the motor is de-energized and no longer forcing them to spin. The sound itself is not harmful. It is more pronounced on 410A scrolls because of the higher operating pressures, and it's more pronounced on long line set installs or high line rise installs. Many scroll compressors have a check valve built in to stop this noise, but it seems like some either don't have one or it doesn't work perfectly. If it really drives you insane, you can have a new external liquid line check valve installed by a tech just off the compressor discharge port. The tech would need to recover all of the refrigerant out of the system, cut the discharge line open, braze the check valve in place, nitrogen fill and leak check the system, vacuum it all down, and recharge with refrigerant to proper pressures and temperatures. The alternative to doing that is installing a compressor blanket to muffle the rattle. As long as the compressor is quiet when running, it is likely undamaged and still perfectly intact. Scrolls make some noise when starting and stopping but they are quieter than piston compressors while actually running.
When a unit is very low on refrigerant, that compressor runs noisy!
The noise may be a lack of lubrication at the compressor and it running in vacuum if it is that low. Mkae sure tpo shut it off and search for the leak, thanks
Won't be low unless there is a leak to fix
Sorry for/and if there is any typos, then/than sorry for them. My phone likes to change them around interest I didn’t say into shhht not I treat🤦🏼♂️🤦🏼♂️🤦🏼♂️😤😤😤😠😠☺️🤦🏼♂️🤦🏼♂️🤦🏼♂️🤷♂️🤷♂️🤷♂️😤😤😤🤦🏼♂️🤦🏼♂️🤦🏼♂️. Sorry
I watch this and dream that my neighbour fixes his 90db loud unit that’s ruining my summers
Wait i thought my AC was supposed to sound like that
My AC sounds like a blue whale when it shuts off... It's loud.
Thoughts?
Is it a scroll or reciprocating compressor? A scroll is quieter while running but much louder during shut down, thanks!
👌🅱oomer
I hate this fucking noise
R right, ok, r right, ok, r right, ok, r right, ok, r right, ok.
Yeah sorry, that was one of the early videos and i try to not do that any more. I used to use that as a visual cue when I was looking around the room to get eye contact and head bobs with my students in the classroom. A hard to break habit. I don't believe I am doing that now on present videos, thanks for letting me know!
