Increase Gas Heat Efficiency Servicing The Burners
มุมมอง 2.1K3 ปีที่แล้ว
I am maintaining a natural gas heating system. One of the things I service on a gas heating system is the burners. There’s several different kind of burners. Yet they all seem to do almost the same thing and that is correct debris and close up. Therefore on this boiler I show how bad some of the burners can get. Two of these burners many of the ribbon holes are closed with rust. I clean the bur...
Troubleshoot Lochinvar Gas Valve : Flame Failure/ Ignition failure
มุมมอง 31K3 ปีที่แล้ว
On this Lochinvar boiler, it will not ignite. I first verify I have spark. Next I verify the gas valve is plugged in. Afterwords I connect magnahelic /manometer to the gas valve. This Boiler operates with negative gas pressure. I watch the boiler operate, looking for the negative pressure to rise to about 0”w.c when gas valve opens. Pressure and ever rises, therefore I checked voltage to the ga...

In this video I show how to safely solder. When wood or anything combustible, is close to what you’re soldering. I am sweating baseboard heat back in after replacing casing
How A Double Pole Contactor Replaces Single Pole Contactor HVAC Tip
มุมมอง 44K3 ปีที่แล้ว
In this video, I show how to replace a single pole contactor to a double pole contactor. This comes in handy for many air-conditioning repairs. The single pole contactor and double pole contactor have a always hot side. The always hot side always has voltage for the loads. The low side of the contactor only sends power, to loads. When the contactor coil gets energized. Therefore oh you have to ...
HVAC Pressure Washing/ Cleaning Evaporator Coil
มุมมอง 2.4K3 ปีที่แล้ว
My customer complains the air conditioner makes a musky, wet sock smell, inside the building. Therefore I am cleaning the evaporator coil. I am using a pressure washer to clean the AC units evaporator coil. First I opened all the HVAC RTU AC panels to access the evaporator. I take a big garbage bag and cover the blower motor and the blower wheel housing. The access panel are used to block water...
Replace Leaking Water Heater Relief Valve
มุมมอง 25K3 ปีที่แล้ว
I am replacing a leaking hot water heaters pressure temperature relief valve. I first verified that the tank itself is not leaking and waters coming out of the relief valve. Before this video I check the pressure of water at the tank. The house’s water pressure was 65 psi. Therefore I first drain down the water heater. Next pay remove the relief valves pipe to send water to floor. After that I ...
Burned Wires Inside AC Unit Connect to Contactor Goes to Capacitor
มุมมอง 45K3 ปีที่แล้ว
I run into two Air Conditioning units that wires melted. The wires melted near the connection to the contactor. I find loose wire connections, which caused higher amps to melt the wire. An undersized wire also can melt. Most of the time the wire melts from a loose connection somewhere in the electric circuit. Therefore I checked the units for any loose wiring. Fixed any loose connection I found.
Installing AC Condensate Drain With Clean Out Port
มุมมอง 226K3 ปีที่แล้ว
I am replacing an air conditioner’s condensate p-trap. In its place I am installing a new condensate trap with a clean out port. The clean out port on a condensate line assist with maintaining a free flowing drain line. I am using 3/4” pvc, 3/4” p-trap, 3/4” tee, 3/4 union, 3/4 male pipe adapter, and a 3/4 pvc cap. Air conditioning condensate lines clog up if not maintained. Clogs can either sh...
Installing Gas Pipe
มุมมอง 95K3 ปีที่แล้ว
I am finishing installing a new gas pipe for a generator. The gas pipe going into house to gas meter passed the air test/ plumbing inspection. Therefore I need to disconnect the test gauge. Then pipe the gas line into the generator. I put pipe dope to seal the pipe threads. The the threads are tampered. The pipe dope allows the tapered threads to seal against each other. Then I turn gas on and ...

Clean AC Condenser with Metal Covers In this video I show how to clean ac condenser with metal shroud. On every air-conditioning maintenance the condenser coil should be cleaned. Therefore I show how to correctly clean the condenser coil. This unit’s condenser coil is covered by metal panel cover with louvers. An HVAC tech needs to get inside the condenser housing. The first thing I have to do ...
HVAC Blower Motor Overheating Shutting Off Electric Issues and Repair
มุมมอง 11K3 ปีที่แล้ว
I notice the blower motor barely rotating, during AC maintenance. Therefore I troubleshoot the three phase motor. I need to determine whether the motor is faulty, or something else in electrical circuit. I find the blower motor wires melted. Next I notice the middle contact for contactor was missing. The blower motor was electric not receiving 2 of three phase. Therefore the magnetic field need...
Testing Air Conditioning Compressor Windings
มุมมอง 6K3 ปีที่แล้ว
I show how to test windings on a three phase air conditioning compressor. Make sure power is off at disconnect. Then take compressor terminal cover off. Test resistance between start (s) and common (c) . Then test between Common and run (r). All these test should be really close if not identical. Next test run and start windings. Any combination tested should yield similar results. A single pha...
Testing Furnace Flame Sensor Before/ After Cleaning Verifying Flame Current
มุมมอง 19K3 ปีที่แล้ว
I show how a HVAC tech tests a gas furnace flame sensor. The flame sensor sends a signal to the circuit board. The flame signal is a micro amp current signal. Without the flame sensor creating the proper flame current signal the control shuts off gas to burners. Therefore, I set my meter up to test micro amps. Next I place one electric meter test lead onto the flame sensors wire connection. Oth...
How I Seal/ Install Threaded Water Pipe Fittings Line Up Boiler Pipe Fittings
มุมมอง 43K3 ปีที่แล้ว
I go over how I seal threaded water pipe fittings. I’m connecting threaded black pipe. I first clean off threads on black pipe. Next I wrap Teflon tape clockwise around threads. After the Teflon I apply a small amount of pipe dope. Now the pipe can be threaded into fitting. I am finishing the supply line off my boiler. When tightening threaded pipe, never back out the pipe, turning to the left....
Damn...I know how to clean. I don't know how to remove.
Thank you for showing me this. Last time I did this I blew a 3 amp fuse somehow
A pleasure to watch a professional at work! Learned a LOT, thanks!!!
you dumb... heat cannot be reduced using water just use cut to 2 parts and you will see bad connection.... stupid video
Set up before you wet up
Great work my dude 😎💯😎
Bring back constructive comments! Just get a 5 horsepower or betweer wet vacuum and suck out the discharge end every so often. Doing this will greatly reduce the chance of a clog at the drain pan nipple and won't overlook the portion of the pipe going back to the air handler. 😊
Literally just did all this and thought let me check TH-cam see if anything else should do. You video spot on to what I just did. Heading to my rental to do 4 more boilers tomorrow
How do you remove them?
Mine just lift up at end where gas is shot into them and pull out. If looks similar to these that probably all you have to do
@@newtoyouproperties683 thanks, I figured out how to get my cast iron ones out
That drain line doesn’t have enough fall for my liking. The “warter” won’t flow out very well.
This guy dont know shit😂 leaks
YOU MUST to learn how to solder ....!!!!!
he is to dumb for that :D
Nice job. What type of gas are you using?
Nice job. What type of gas are you using?
The instructions for the primer and glue I sold at Home Hardware are different than the instructions you show in your video. They say to prime the fitting, prime the pipe and then prime the fitting again. Then you put glue on the pipe then the fitting and a second time on the pipe. I see that you prime both the fitting and the pipe only once. Then you put glue only on the pipe and use just one coat. Is this how you do it for all PVC applications or just for this because there no pressure to cause it to leak.
The Drain line should have an air vent after the trap....
Where is that required by code for condensate line? I know that plumbing drain lines need to be vented, but I've never heard of that requirement for condensate. I think they're generally empty enough that they vent themselves - b/c they're generally draining to atmosphere.
@@sowellfan perhaps a cap on that cleanup and then a vent that opens below the level of the top of the trap so if there's a backup, it'll also drain out of the vent instead of the backing up into the system, unless it's connected to main drain?
That's what I thought. I put a cap on mine and it started going into my backup pan out my backup drain line to my garage driveway
Do you recommend keeping a cap on the upward pipe or is it ok to have it off? I'm asking because our house was built 2 years ago and the builders never put one on.
Being open and very accessible I would do sharkbite...but what do I know
My drain pain is rusted out. Is there a way I can fix it epoxy?
I have that same system. My coil is leaking freon. I have to recharge it every 2- 3 months. Can I replace my coil? Where do I buy it?
Great video !!!
BA- BOOM! good video
ok so your old drain is not up to code and pitched about 15* downhill, your new drain is not up to code and pitched about 15* downhill but has a Union ... which does not satisfy the new standard for a non destructive method of cleanout. just gives you an opportunity to make a bigger mess. a second union between unit and trap would work ... you haven't satisfied the IEC mandate for Condensate pipe insulation. or the IRC standards for overflow protection. and for modern equipment a P-Trap isn't deep enough, a j-Trap is required.
Can you cite some chapter & verse here on your code-talk here? At 2021 IMC 307.2.5 it says, "Condensate drain lines shall be configured to permit the clearing of blockages and performance of maintenance without requiring the drain line to be cut." - seems to me that his setup here doesn't require cutting of any drain line for maintenance. Also, I'm not seeing any code requirement differentiating between P-traps and J-traps. What kind of install manuals are you seeing this in?
Very good video. My A/C drain line comes out from the pan, makes a couple 90% turns and connects up to the PVC drain that goes to the floor drain. I don't see any P trap. Should I install a P trap? Does your PVC cutter cut the pipe straight? I had purchased one that cut the pipe but the cut wasn't perpendicular, it was on a slant. I returned the cutter. Do you have a recommendation for a PVC cutter?
Never knew you could clean those. 🤙
Nice work! 👍
I added a HS kit. I also went from a single pole to a double pole contactor. Should I hook the HS relay BEFORE or AFTER the my new switched pole?
Before the contractor would also basically mean your whole house would use it too
what type of wire you used to connect the capacitor to the contactor? Mine is cooked so bad and I can't see any markings on the side.
That was so awkward to watch
😂😂😂
Can I use a spade contact for a car?
Nice video, thank you!!
Hi Bill . I have question for you . I have cast iron boiler made by slant fin , it is direct vent Victory model . Boiler is over 20 years old by now. I removed old circular pump on return side of boiler do to pump rusted and leaking water . Treaded part of boiler on return side have internal threads it 1-1/2 diameter and they are not in prefect condition do to age of boiler , I can still able to thread new pipe in boiler . My question is how do you sill this old threads to make leak free connection? Thank you
So, if it is in the summer, and the compressor heater isn't required. You can at minimum substitute a two pole with a single pole without any concern? Fan dosen't have to be hot?
Amazing step by step tutorial. Thanks a lot!
Hello - i have a few questions... this looks similar to what we have in our attic. What if the clean out isn't capped off, does that cause problems? If you know there is a clog and want to use the air compressor to push the clog out of the drain, can you use the clean out spot or is it better to create one of those sections where you can easily take the PVC apart?
If it's ur house,you shouldn't care..only if it's not urs
If you have a tee on yours like he installed on his, it should definitely be capped. You can look up static air pressure. Basically it will pull in air so much that water will stay in your pan and potentially overflow. As far as the air compressor, I feel like that is preference based. In my opinion air is a quick solution to get it clear, but flushing with bleach or vinegar will probably suit you better.
The T should never be capped off , leave it open
So I have a question. What is the trick with the pressure washer. My boss told me I need one to clean the coils, so I bought one. No idea what I am supposed to do. Do I just aim straight and hope for the best or is there a trick.
You did'n't relieve the pressure first by opening a hot water faucet
Just had a unit installed 5/6. AC stopped working this morning 5/12. Called the installer which doesn't have the greatest reviews, they came out and found a burnt/melted wire on that side of the contactor. Said it had to be a surge and charged me $321 for the repair. I know that is. You know that's bs. I have no problem stopping the check.... however, what do I need to do to assure this doesn't happen again? It's a brand new unit. Do I need to pay another company to come check everything or can I just check certain connections?
Same situation for me
Very good, basic electrical knowledge
Thank you
❤
guy is spot on here great work
Whoever brazed those lines didn’t use a fire blanket or brazing putty lol
do you remember the psi you used ? thanks
No eye protection, heating the copper pipe with a direct flame as opposed to heating the body of the valve. C- at best.
I thought you are not suppose to heat the body of valve since it could burn the rubber ring inside?
Using a wet rag is not a a good idea.
What problem(s) arise from using a wet rag?
@@JonathanScheelei believe it rushes the curing process and can cause cracks in solder
