Run as fast as you can away from these people and the AC pro products. I sympathize with a previous reviewer where he explains that it takes a licensed professional to get a proprietary part.
There is a rating system online that shows Lennox, which owns Ac pro, as second to last in quality.
It's a racket, they say that AC pro is more of a mom and pop product as opposed to the nationwide known Lennox brand. All they are doing is going into cahoots with local hvac service people to cut out the owner from the Service and Parts replacement game.
When my four year old, 5 ton, forced air unit started giving me problems with the gas valve and ignition process, I called my friend who does have a license. he gave me a good deal and $2000 later, in parts, I still do not have a working heater. He keeps referring back to the AC pro tech-support, and each time they tell him to replace a new part, all done in vain, because it still does not work.
Finally, I decided to take matters in my own hands and I contacted AC pro myself, but they said they would not talk to me because I was the homeowner. I'm inclined to sue them to replace the two units that I had installed in 2020. Please search "AC Pro sucks" to see my YouTube clips .
