Seldom do you find an HVAC contractor that is as knowledgeable and professional as Mitchell Heating & Air. He responded quickly and resolved my AC issue. In addition he checked out my other unit at my request and found a small issue with it as well. Both issues were resolved and the house is cool again. So pleased to have been referred to Jason. Mitchell will be my go to HVAC contractor from now on.

These guys are my go to team for all the houses I build. My last HVAC company couldn't figure out everything required when Denison switched to the new energy code, I switched to Mitchell Hvac and everything has been smooth sailing since!

I have never had such a delightfully pleasant experience when dealing with an air conditioning system. Our house is new and the air conditioning system was not working one afternoon upon our arrival home. I called Mitchell HVAC, it was after hours. Jason answered and was at our house immediately. He quickly fixed the problem ( a switch) changed our filter and put fluid in the air conditioning. On Monday the same thing happened, he immediately called the electrician and had the switch replaced. All of this transpired over Memorial Day weekend. It was all taken care of quickly, correctly and in such a helpful and kind manner; one I will not easily forget. I am so VERY grateful for and to Jason Mitchell for his expertise, of course , mostly for the kindness with which he treated me. I will recommend Mitchell HVAC as long as I am living in Denison. Thank you, Jason!!!!
