What happen when A/C continuous running none stop, don’t that cause system to freeze up ?

[Matthew-jrxr]

Why go to college when you can watch this guy's channel? Haha. Watch the adds, like, comment, subscribe, whatever you can do to help him out. Lord knows he's helping us. 👌

Craig You are the
Guru of Air Conditioning.

Learned more from this video than the college I went to in less than 20minutes

[billb.]

Nice video. Your explanations are top notch. I learn so much from your videos. I really appreciate all of your effort to pass along your knowledge.

[MichaelHernandez-lcwb]

What a perfect, concise, and clear explanation. I cant thank you enough!

[joecooksey]

Off topic, but you did a video a while back on p-traps. That video is SAVING me $$$. Here's why. 4 ton split 13 years old. It did NOT have a p-trap, but had a decent trickle of water coming out the PVC. I never thought much about it until I watched that video. I installed a Rectoseal trap and dropped the humidity 3-4% (46-47%) inside allowing me to turn the thermostat up 2 degrees. I now have an excellent stream of water coming out the drain! THANKS A MILLION!

Thank you. I have a liquid line restriction issue. Now I can speak to my AC guy and tell him quit screwing me over your fired. My guy has been leading me from one thing to another charging me a fortune. Today he said its a leak I need a new Furness but he never perform a pressure test.

Saved into my favorites category for HVAC to pass along to others 👍

[vernroach]

Another good one...Even my brother understood it and he's not in the trade...Thanks again.

Graig - You were born for a big reason. Thank you so much !

Sir, you're an amazing teacher. So clear and concise. Thank you!!

[Zolt]

Always so well explained, this guy taught me a lot to improve my skills several years ago. Certainly learned more with him than at school. 😀

[thecoolguy]

Kink in the lines could be another reason for refrigerant restriction!! 👍👍👍 Good video 🤩🤩

Hi sir I'm bert in Philippines 🇵🇭 I'm learned to much in Refrigeration I'm very interested

[Andreggs-vk]

I understand English but i have many friends in the field that only speaks spanish! I wish u had this videos translated much love! ❤❤😊

[dougjones]

Thats quite the mic for an hvac guy. Great info thanks

[wildbill]

WOW, that was comprehensive. There was alot of water in the pan below my coil and it was not draining - which it should. I sopped up all the water with a sponge and discovered that the lower part of the coil is frozen. The filter was sopping wet, so i got rid of it. It was installed 5 mos. ago, but appeared clean. I had no idea I was supposed to change them every 30-60 days.

I checked the outside drain and the ground is all wet, so I don't know if it's clogged or not. I cleaned the coils inside and out before the season, so i know that is not the problem. I'm just going to leave the filter off overnight and see if the increased air flow helps defrost the coil. If not, i will call the HVAC tech and see if the TVX valve needs to be replaced.
