Welcome to Hamstra Heating and Cooling

Your Arizona Heating & Air Conditioning Experts Since 1983

As Tucson’s premier air conditioning and heating specialist, Hamstra Heating & Cooling, has been serving the Tucson area since November of 1983.

What makes Hamstra Heating & Cooling different? All the heating, ventilation and air conditioning companies in Tucson and Southern Arizona can sell you units and ductwork, and can all install them, but it is the level of expertise and service they provide to you that makes all the difference. Hamstra HVAC cares about the quality of service you receive. We have over 20 technicians who have earned the North American Technical Excellence designation through extensive training and study. No other company in Arizona employs that many!

Our value added services have allowed us to grow into one of the largest heating, ventilation and air conditioning companies in Tucson and Southern Arizona simply by word of mouth, all without ever sacrificing the quality and service you deserve. In fact, we have received the prestigious Angie’s List Super Service Award for five straight years – 2008 to 2012! How many other companies can say that?

What Our Customers are Saying

Hamstra installed the original systems in our home 20 years ago and have provided excellent and timely service whenever we called. We recently replaced our two aging heat pumps with new models and were extremely satisfied with the professionalism and responsiveness of everyone we had contact with at the company. We recommend Hamstra to friends and acquaintances whenever we have the opportunity.
