*So amazingly quiet and **Fastly.Cool** in my room! 42db is at a whisper level. I bought 2 and installed myself.Very sturdy bracket and easy to adjust to fit windows of different size. Absolutely fabulous units!!*

Simple, Clear, Accurate, no blaring background music. One of the best posts I have ever seen on Youtube.

Thank you so much . My air conditioning froze up today. I have change the filter in the air return. But I did not realize there was another filter in the heating unit where the air flows thru. So once I defrost I will check that. My dad died last year. And mom is clueless on everything he did about the house. They just had this unit installed last year before he died. And she can not find her paper work. So you have been so helpful. Thank you very much.

Thanks for a good explanation. I have another reason for Ice-up on my AC unit. My digital thermostat was malfunctioning - turning on the compressor and not the fan. The lack of air flow that you mentioned freezes it up pretty quick. Thanks for confirming that the lack of air flow can cause icing.

Thank you for your thorough explanation!  This was very helpful to us when we had difficulty with our a.c. unit.

Thank you so much I'm new to the field and had a compressor and sucton line In ice and I knew it was a leak in the system but you also said that if you block all the vents that can be the issue as well.

Thanks allot Mark and team, you just made me find the reason why my conditioner was freezing. It was both air bockage and a dirty filter. Thaks for sharing your knowledge to the world. Greetings from Monterrey, Mexico!

Excellent video, blazing summer heat and the ac is constantly puddling water under the handler. I changed the filter and hosed down the a pillar which was full of dust(desperate maneuver). I check the drain line and it's clear. I think it's low refrigerant and me having the vent in the second bedroom closed completely. A combination of things. Great video thank you.

Thank you for this free information. Seems nothing’s ever free anymore. I had a new heating cooling unit installed in April, this is September and I can’t cool my place any cooler than 80. Finally, today a tech came out and fount it was frozen, no one ever looked before. Had seven service calls. My thought all along was that there is a restriction or a leak, because it’s colder in the crawl than the house. I don’t understand the a/c process, but, now I see why little clearer. Thanks again.
