Wyatt Cochran/ Certified




Review of Certified Heating and Air Conditioning

I have no complaints about Wyatt & his team. All I can say is They did a great job. Wyatt can installed two furnaces within 2 days. Wyatt was so patient and smiled face listening to my complaints for hours. I was not happy about the first one he installed then replaced the 2nd one per Galen to satisfy my request. Nothing I can say, great job & great team work. Thank you very much for being honest to me.
