In the summer of 1991, Dusty & Gail Cyphers started Cytech Heating & Cooling, L.C. At that time it was just the two of them and one other employee. However, before long word got out that there was a new service company in town and business took off.

In 1994 it was time to expand and the office on University Drive was purchased. This offered more space for the ever growing staff and good exposure to the community. Cytech Heating & Cooling, L.C. is still located at the same location, although it is not as roomy as it once was.



At Cytech all our technicians are highly trained and certified. They participate in continuing education training throughout the year to stay current of changes in the industry and keep their skills sharp. Most of our technicians are NATE certified which stands for North American Training Excellence and is the highest standard of testing available in our industry.

Cytech is also a Premier Dealer with Lennox Industries. To become and remain a Premium Dealer, Cytech must achieve and maintain a high level of customer satisfaction.

I wanted to complement the service. I had my AC go out on Sunday afternoon and had a service tech named Edgar here in about an hour and a half. He was friendly and efficient. The AC was up and running in about an hour.
