AC Not Working Right? How to Check if Your Air Conditioner is Working Properly

[@pattipayton1163]

Best video advice I've ever watched

[@Gunturkaaram5544]

Really your video was helpful to me. I saved my money. Problem was in the mesh. I cleaned it. First my husband said , recently I cleaned it. But I insisted to open that mesh. It was full of dust. Now it is far better then before. In this this season it is too expensive to get it checked by an expert. Thank you very much.

[@thomashandza3258]

Very good video. The supply and temperature difference was good to see. Especially the different locations on the supply/cold air side. I use the formula of delta temp X cfm air flow X 1.08 = btu/hr to check against the manufacturers btu/hr rating at when the outside temp is 95 deg. Recently my unit was recharged with refrigerant but only got to 75% of rated capacity. The rated temp difference is 25 deg and the unit only got 19 deg delta. I m wondering if the contractor did not put in the full 9.8 lbs of 410A refrigerant. Can you confirm the use of this formula? Dt x cfm x 1.08 = btu/hr Tom Handza

Great video I’m on the threshold even no filter for testing. I noticed slightly louder compressor noise in the house while running than usual. Any ideas

[@kawansculpture]

question ? this year I start my AC but I forgot to unwrapped the cover for half an hour , since than my AC doesn't give any cold air , I think we damaged the unit what is your opinion please ?

[@ivanorellana7086]

Man excellent advices Awesome knowledge great tips Question what's the best brand on an Ac Unit

[@WordofAdviceTV]

Thank you! Here is what I think about the best brand for HVAC: kzbin.info/www/bejne/eaqXZ6yKl9CBnqs

[@jasonhayes17]

Great video so if the large like isn’t cold or has no condensation on it what could the issue be

[@WordofAdviceTV]

Usually this means that either the unit is low on refrigerant or the compressor is not running. (only the outdoor fan is spinning.) I would suggest this video to start with: kzbin.info/www/bejne/fYC7mJekh6drapIsi=6-zonMebF2u1ZSow

[@jiggeraguilar3631]

The thick line (suction) hose is dry, while running the unit. What does that mean? I can tell the difference coz I have 2 units out side, the other one is running and the Suction line is cold. Thank great video

[@cryptickcryptick2241]

So one should look at the coils outside and make sure they are clean. Fuzz from plants, leaves, grass, dirt and more can get in the external coils. This can be gently washed off with a garden hose if it is dirty. One can also use a mild soap like dish soap and a spray bottle or garden sprayer, just be gentle and don't bend the fins. Never use a pressure washer. One should check the condensate drain and make sure the water is coming out like it should. One can also inspect the all the ducts and make sure they are delivering the air where is needed. Ducts can go through crawl spaces, attics, and other areas outside of the home and it those cases, that cool air can be lost to the outside.

Great videos man Si helpful thank you

[@annewaggoner638]

Great videos. You know your air conditioners! My issue is new home with cooling portion of electric bill $40-70 dollars more than people in my neighborhood. They have given me their information to show Ac company. keep thermostat at 78. Small home. Still under warranty. No one can find a problem. Any suggestions?

[@Ahmed-vg6gh]

Did you figure it out? I'm facing the same exact issue and noticing high humidity inside the house 70%

[@francisperez3615]

Great video, thanks for sharing! I'm just wondering why my delta temperature is just 14. I maintained my A/C unit every year by cleaning condenser coil fins every spring, checking electrical parts and regularly change my filter. I notice that the forward air temperature is just 65 degrees Fahrenheit. I saw your video and you have around 55 degrees. I set my thermostat around 77-78 degrees and my A/C cools the house or I say it reached the set temperature normally. What do you think is the problem?

[@WordofAdviceTV]

There is a chance that you are a little low on refrigerant but if it reaches the temperature you set it to and cools down the house good, then I would just leave it alone for now.

[@francisperez3615]

@@WordofAdviceTVI've also notice that the big pipe is not sweating as before... it's cool to the touch but not sweating.

[@WordofAdviceTV]

@@francisperez3615 Yeah... That's another indication of being a little low on freon. Another possibility is that there is a problem with airflow. But it sounds like you change your filter regularly so that's not likely.

[@mikem1014]

can you use lazer temp gun an can you test at supply in different rooms

[@michaelhinchey]

If the unit is on and running but it won't cool to the temp you set the thermostat , what are the places to check?

[@christinehoward7867]

I wanted to know the same thing

[@charlieparker5678]

Don't know if you're still responding to this 3 year old vid, but I got a question. Can you find what the temp is on the supply duct by just sticking your temperature probe through the louvers of the supply register rather than sticking it through the canvas? (The air handler is in a closet so I don't really have access to the ducts)

[@Ouimayo]

Yes you can, the temp diff won't be as exact but it will still give a good enough reading.

[@erickauffman6155]

Great content in your videos, thx for sharing!

[@dclsally]

I checked capacitor it lis good. I pushed contactors compressor turned on good with immediate cold at output host. Double contactor has no 24VAC supplied to turn on compressor while the thermostat in room is clicking correctly according to setting. 24VAC is coming from attic where the A coil is located. The thermostat fan mode itself also not working. Is the defective fan in A coil prevents 24VAC to activate compressor to send cold agent to it so that A coil is not freezing up? What is your diagnostics for this problem? Thanks for your promptly reply.

[@WordofAdviceTV]

If your unit is in the attic, I would suspect a tripped float switch. Have you checked if your condensate drain line has any blockage? This article is a good start: acwiz.com/index.php?action=artikel&cat=18&id=26&artlang=en And usually even with a defective fan, the ac unit outside will still turn on. Also, if your furnace/air handler has a 3 amp fuse in it, check that too. It may have blown.

[@jarrod6424]

My big pipe is dry, would that mean low/no freon? Love your videos!

[@WordofAdviceTV]

Glad you like the videos! That is an indication of a problem but doesn't guarantee that you are low on refrigerant/freon. If your unit is not cooling the house down then most likely that's exactly what it is.

[@NOUNOUDZ100]

Thank you so much , I have a question , my AC is working but it takes time to cool my house , it will take more than 24 hours to go from 81 degree to reaches 74 degrees, he is not like before

[@sunlite9759]

Check duct work for damage, insulation or gaps. An older house may have poor insulation. Up grade windows,

[@matthewlantigua4181]

The seating on the outside means that the temperature of the pipe is close to the dew point. I live in a desert, with a dew point below freezing, so it would pretty much have to frost to condense. Should the pipe temperature be about the same temperature as the air flowing out of the ducts?

[@abrahambonilla863]

I replaced capacitor, unit comes on when plunger is pushed in on contactor but not when I turn on thermostat. Thermostat turns on fan when I place on on, but it will not cool. Any suggestions?

[@AaronHatcher]

Replace the contactor. But I'm having almost the same issue except the plunger goes in. Mine won't cool at all. I replaced the capacitor also. But if you're won't plunge on its own then it's Def a bad contactor

[@Devildog8614]

Same problem did you figure it out?

[@LArider57]

Can a bad thermostat be an issue too?

[@robbieboomrang990]

old batteries in thermostat should be changed

[@Nadgpeiralv]

My AC has 5 degrees difference from supply & return ducts. Supposeley compresor was replaced and expansion valve as well Any ideas what could it be??

[@leevinca6651]

Great videos, can you help with my ac. Once house reaches temperature the ac unit still continues and doesn’t shut off on its own. Any suggestions

[@ricardogarcia4523]

It can be that you have the wrong type of thermostat or thermostat is not working, it can also be that the contractor from the condenser is broken.

[@TheAsmrVoid]

Hey bro, I'm having a problem where my unit would not turn on, I've checked the contactor and it does not stay in, whenever i push it in everything works fine., is there a way that you could bypass it?

[@Tiffany.Detailer]

So our AC has been set at 78 for at least a year and working just fine. My dad passed away from Covid 11 months ago, so my mom is selling our home. The buyers sent out a tech to check the AC today, and as soon as he left, we noticed our air conditioning was 81° and rising even though it’s set to 78. We’re in Arizona so it’s over 100° at night. The company won’t have someone come back out to look at it without a $75 fee, and we don’t know what to do. Any ideas? This sucks and my mom has been through so much. She wasn’t even home, our AC was working great for years until this guy came out.

[@HoneyGoyal-o9r]

I checked my ac temperature in both lines but different is 7 degree so what I do know

[@stevenflores7662]

What is suction line is not sweating just cold?

[@WordofAdviceTV]

Here is the thermometer I used: amzn.to/2tYGESV

[@marthagreenlee6850]

The A/C out side in my back yard doesn’t stop When the A/C inside the house Stop the ciclón, the out side is kipping running it doesn’t stop what’s could be ?

[@NOUNOUDZ100]

My Ac is working but very slow , it takes 24 hours to go from 82 degrees to 74 degrees , before in few hours now it takes time

[@kdshenderson]

Mines doing the same. Did you find out the problem?

[@Iamdone1024]

The big pipe is actually all iced up... Does that mean my Ac is broken?

[@juliantrujillo8560]

This guy have so many videos on troubleshooting your ac ,you should go to his word of advice tv playlist and you will find your answer ,before you call a technician ,may be is something easy to fix good luck

[@rootkitxx]

He has other video, low on freon when iced up

[@enriquemeza8268]

i nedd a book in spanish about questions &answers of 608 epa

[@NOUNOUDZ100]

I did replace my capacitor but still the same

[@akanshatanwar2397]

what r d signs to check ac cooling is proper or not

[@WordofAdviceTV]

The temperature difference of your return duct air flow and supply duct air flow should be about 15-20 degrees F. As shown in the video. If it is less then 15, like 10 for example, then you either have an airflow problem or you are low on freon.

[@mimbreno87]

My big pipe is frozen so what does that mean

[@WordofAdviceTV]

There could be a couple of reasons for that: - Very dirty furnace filter - Dirty/plugged evaporator coil - Blower motor in furnace stops working after a while - Unit is low on freon - There is a restriction in the metering device (freon related)

[@WordofAdviceTV]

I will try to explain.. Temperatures and pressures correlate. So when the pressures are lower, the temperatures are lower. When your unit is leaking out freon, the pressures will go down. Average freon temperature that is inside of your refrigerant pipes (suction line) is about 38 degrees. When the pressures go down, the temperature of the freon will go down as well. Once it drops below 32 degrees, the condensation that your evaporator coil collects will start to freeze. The longer you run your unit like that, the more ice will build up.

[@WordofAdviceTV]

Unfortunately when it is freezing up like that, it will likely require calling someone. You would need at least a little bit of an HVAC background plus the necessary tools to try to fix that. And yes, when it comes to freon issues, the bill builds up in a hurry..

[@mimbreno87]

So update a buddy of mine was a HVAC tech he came and checked it out there was no leaks I did change my filter though cause it was dirty as shit honestly hadn't changed it in a year. The freon was a lb or more low got the r22 my buddy put it in and now it's working great

[@tyroneandrebeccagibson3684]

My AC has a HL code “ but” there is no water in the unit…what wrong?

[@jglacierr]

Bro says if it’s dry, it’s bad. But doesn’t say what that means or how to fix it.
