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

Never would've guessed something as simple as the condensate safety switch. Used my shop vac to remove the water from the pan and the unit instantly kicked on! This video was very helpful. Thanks! 👍👍

Thank you for the tutorial, my A/C went out on one of those 100 degree days, my HVAC guy was out of town and I would of had to wait three days til he got back. I don't trust just call any repair services from my experiences with dishonest or over charging, so I stick with one company I trust, anyways I changed my capacitor on condenser, still didn't work, when you mentioned checking the thermostat by jumping the connectors nothing happened, then I went up into the attic (100+) I found the condensation safety switch in the drain pan was a little tweaked, realigned it and cool air was back, thank you very much you saved me a lot of money and being miserable for days in 100+

I couldn’t find a video to where the inside blower and the outside unit wasn’t working and I almost didn’t watch this video but I’m so glad I did, I started by using a jumper wire at the thermostat and nothing so I checked the control board and remembered I use to see a green led light on the board, so I pulled the 5amp fuse and BINGO! I already had an extra fuse on hand.
Thanks for the video!

Yo I've been stressing about my condenser shutting off for the past 24 hours. We had my gf's mom over yesterday for a labor day grill and the ac stopped working! I panicked and spent some time in the heat trying to figure out what could be wrong.

i woke up today, hot, and worried that I would have to replace my entire unit for thousands of dollars...was about to call an AC company but decided to watch this video. When I got to the part about replacing the batteries in the thermostat I scoffed, but figured its worth a shot at least. There's usually an indicator that says low battery, but since you convinced me to try it, I changed them despite the lack of any indication of them being low.

Imagine my relief and joy when I walked outside to a spinning fan in my condenser.

Thank you sir, you probably just saved me from someone trying to scam me into buying a whole new unit.

I've been laughing with relief since.

Thanks for the video!

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

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 .

[kryknow]

This is by far the best channel I have found on ac repair. Very thankful for this

[mikelroper]

The tip about the switch was super helpful. Our A/C condenser dumps water into our sump.
When I replaced the sump pump, I must have pushed water back into the system causing the switch to trigger. Although the switch is different and doesn’t have a reset, I was able to twist the switch allowing the water to drain and move back to the original position.

The A/C started right up.

Thanks for the great video!

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

[kennethbearden]

Got a new Smart Thermostat and after installing everything went black, after viewing your video I was able to fix it myself. Was a $4 3amp fuse. Good info you have provided. Thank you

[dansmego]

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

[Drone]

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!

[kenrwall]

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

[romarro]

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

[zhfhons]

Very informative, not generic. I learn things that others don't say or go into more detail about. Thank you! and Kudos.

[catieman]

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

[dougwolverton]

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.

[kayjay]

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

[Wesley]

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