I read some of the bad reviews on this company an have been ripe off in the past but one of there techniction come out and quoted me a very fair price to fix one of my unit and he was very informative on the information. About my units. He did not try to sell me on any extra covered or pich me as a sales person would, but just told me what was wrong with my unit. An repair it, an also help me set my thremstate to keep our house a lot cooler. I will be definitely calling them in the future.
