I cannot express how thankful I am to you. My system shut down in NC during this 100° heat wave. Turned out the system in the attic was filled with water. I sucked out the water with a shop vacuum and it fired back up again with no issues. Tomorrow I will cut the evap pvc pipe, clear it out amd use pvc unions to reconnect it. Sir, you saved me a fortune. Thank you so much!!!!!!!!!!!

You saved me a couple hundred bucks. Thank god for people like you

Thank you for the time you spend every day making these videos

Best most complete video on HVAC troubleshooting by far!!! Thank you! Very informative and professional!

Video is excellent. Straight and to the point. Very clear.

That lightning bolt scared the crap out of me 😅 great video for people learning simple diagnostics on an AC!

Problem #5, was my situation. Your video saved me a service call and one day of 95 degree weather. Thank you very much.

Great video! I had these symptoms and using the jumper wire technique to bypass the thermostat revealed it was the problem!

Watching from Toronto, you just saved me tons of money, did the trouble shooting turns out it was my thermostat wire that’s bad. I jumped it directly from my furnace and everything works ! Thanks for your help!

Mine was problem 4! Thank you , saved me some money & time! It was 93 degrees outside in Texas today definitely needed that Cold AC

Number 1 problem for ac system not running after 30 years in Hvac business is condensing unit capacitor bad . 8 out of 10 summer service calls are capacitor .

Problem number 4 was mine, and thank you for educating me on that because you saved us a lot of money.

Thank you for the 10 tips I just fixed my Ac with your help.

You saved me a bunch of money! It only cost me $1 for a 3 amp fuse once my AC went out. It went out because I wired the thermostat wrong but it at least is fixed. Thank You!

Thank you for your suggestion on the 3 amp. My fiance didn't think about it when he was trying to get our AC to work. Your video is so very much appreciated.

Well done. Very informative. Thanks for sharing.🙂👍

Videos are always well done and informative. Great information for seasoned techs that want to refresh or new guys looking to learn.

Excellent video! Very informative. Thank you

After spending figure why my smart doesn’t power. After seeing your video, fixed it. I love ppl like you making video like this for ppl like me no a handing man

You are an amazing human being! We're about to get a heat wave starting tomorrow and lost power to the thermostat. Thank you so much for making this video!

You are amazing!! Thank you!! I wish i would see your video before my Ac. Broken.

Thanks you again always great video

Thanks man! Tip number one solve my problem. I really appreciate the video!

My issue was the little 3 amp fuse which I figured out thanks to you but only after I replaced the capacitor. Thank you!

Bad control unit, thank you so much. Bout to go crazy trying to figure it out!

Thank you for the tips mine was the metal door button wasn't pushing all the way in I taped it put door back on and now sitting in a nice cool house ty so much saved so much money calling someone out here

THANK YOU!

For me it was the fuse. It was 3a and I had a 3a. Started right up. So many thanks. And really liked how thorough it was. I have found and replaced capacitors before but not a fuse.

Thanks man

Your videos very informative. I have a bad 3amp fuse. Thank you

Hi! Thanks for this video. In the past couple of months, sometimes when we push the thermostat down a few degrees, it won’t trigger the on. It’ll flash “cool on” but the AC doesn’t turn on. I then turn off the system and then reset the circuit breaker. When I turn it on again it starts working. It doesn’t appear to be a condensate drain line problem as water isn’t backed up. Also, the unit is only 2 years old, got it installed a couple of years ago. Do you have a sense of what this could be? I don’t understand why it always works after resetting the circuit breaker for AC. (The breaker doesn’t appear to be tripped when I reset.)

What kind of multimeter would you recommend for testing the capacitor and other AC components?

Thank you so much sir it was the float switch worked instantly

Thx. Safety was tripped

On a electric/gas unit.. Does the furnace need to have propane going to it in order for the ac to work in the summer time?

Hi Craig, I have a question, I bought the digital version of your training book and is not on play book anymore, was that a temporary version?

Fuse , breaker ,capacitor ,contactor ,thermostat are some issues or if it’s a heat pump low charge , good stuff I was just going to say common wire too

I've gone through these potential problems and can't find out why the unit suddenly stopped. The only anomaly I found was all lights are out on my Honeywell HZ322 controller and it's getting power. Will a unit not start if the zone controller is dead?

Looling for suggestion: AC unit went out and the capacitor was changed on the first service visit. Was told need a new unit but Choice warranty approved to change the compressor instead. Ok, compressor was changed yesterday and house back cooling. Here's the issue, the air filter needed to be changed so I head up to attic (turned off AC at thermostat) and changed the filter. Turn thermostat back on to cool, and the AC unit outside never kicked on. Checked breaker and everything and still does not come on. Any suggestions on what it could be? Serviceman cannot come back out until next week. 😩 Thanks in advance,

Would you recommend changing capacitors or fan motors based on time (21 years) as a preventive measure?

@lanceestes5980

Check MFD on the capacitor. That’s how you test to see how what they are currently running at vs what they are rated for.

How about some mini split items also my system is a 3 head mitsubishi system it only had 1 service call in 6 years

My ac unit at this rental looks older than anything you've showed. Their is a pvp pipe coming out, but it's just ran down the side, and then parallel to the ground, down to a drain in my basement. Not scorching yet but it is almost 80 and ac unit won't work. Landlord said he will get someone out here tomorrow. Worst part is I absolutely can't sleep when I'm hot. I keep it around 65-67 when I'm going to sleep. 😪

On the thermostat why are there two numbers? In the daytime should it say DayTime or Run?

Hello, I live in South Florid and I have a brand new AC (2 weeks old) ever since it was installed, it runs for about 7 minutes every hour or so. The Thermostat states the temperature desired is reached, and therefore it just turns once (for 7 minutes) every hour. We set the temp for 72 before bed, and it will just run these 7 mins per hour to maintain that temp. Now, if I lower the temp by a couple of degrees then it will run for about 12 minutes… However, still just once per hour. Please let me know what could be the issue. Brand new Ac/Thermostat.

I had a new fan motor and capacitor replaced just over a year ago and am having the same issue. When I first turn on the cool setting, the compressor would kick on and try to start for about 5 seconds then shuts off. Only the fan would stay running. I need to shut off the thermostat and wait a few minutes to try again. Then on the 2nd attempt, the compressor would stay running and continue blowing cold air. Is it a possibility that the capacitor has gone bad in such a short time?

I’m here wondering how to find my AC control panel? I live in Phoenix in a condo, there is no indoor furnace. AC unit is on the roof

Thanks so much for your information. Worked like a charm in my case and I'm a true novice.

Excellent!

Oh the nest the number #1 issue with those are the common wires not being connected at the time thermostat or at the air handler or period due off factory charge . I always check to see if common is connected, not recommended but I grab a little piece of wire and barely touch r and c to see a little spark (ounce again not recommended) keeps you from going in air handler attic up stairs etc …. You know common is connected SO I then hook it to the thermostat or connect it at the board air handler etc..

Where does one find a brush like that to clean the tube

Just to mention I learned about the word tau , and the capacitor charges up and then discharges in 5 tau. ! 1 tau. 2. Tau. 3 tau. 4. Tau. and 5 tau The capacitor will start a motor up in 5 tau then the contact will close if I remember really well ! The capacitor and contact combination are a parallel combination in series with one leg of the motor or one hot wire!

Oscilloscopes are really necessary when diagnosing Hi voltage alternating current motors!

I had the condenser unit capacitor changed, I changed the batteries, and the breaker was not tripped. The thermostat screen is blank but the fan still runs. But the AC unit does not turn on. Any ideas??

I have problems today. Unit works on cooling but not working on heating ? What could be the problem?

Ours stopped working then randomly started up but now it’s not working again. So I’m not sure which step to take first

8:30 I tested a capacitor last year and it tested good but when I shook it, I could hear it. It was bad, but why? Thanks for the awesome video!

Sir can u send me a copie or booklet of technical details on ref n ac systerm.

Pressure Limit Switch is tripping. (Located outside on A/C unit). Fan will not move on its own unless knocked with a screwdriver. Unit itself was very dirty. Smaller diameter copper pipe was HOT to touch.

Went on a two hour drive once just to turn on switch. Inspected unit found nothing wrong was not very happy about that call lol

That’s very true. If you’ve verified your thermostat is working correctly and your AC unit still doesn’t come on you’d jump from R & Y at the board NOT the thermostat which would lead you to the outdoor unit not getting the Y signal to your contactor

You just saved me from having to call the hvac tech. Blessings upon you and your family. It was the thermostat, not the outdoor unit. Thank you.

My window AC buttons/control panel suddenly stopped working yesterday. The AC was at 68° then the buttons/control panel stopped working. I played around with the buttons and it went down to 60° and then I wasn't able to move it back up or even turn it off or on. The buttons completely stopped working. Then today I pressed the off button and it surprisingly worked, but now it isn't turning back on at all. It's 100°+ And I have no AC!! Unfortunately I don't have the tools or money to fix it
