Carilion Clinic Logo. My office complex in Tucson has 20 AC units that service 10 thriving businesses. Hamstra Heating and Cooling has been regularly servicing our AC units for years and the results are terrific! As a retired Dentist I am a believer in regular maintenance and early detection and repair of problems. This is Hamstra’s approach as well and they keep all my tenants nearly free of AC problems. In the rare event of an emergency Hamstra is always right there to take care of the problem.

I’m sure that Hamstra Heating and Cooling will exceed your expectations both for your home and for your commercial needs.
