OVER 1,500 5-STAR REVIEWS

“When our 21-year-old furnace and air conditioning unit started pulling 3 amps more than it was rated for, I knew it was time to replace it before facing another brutal Tucson summer with 110+ degree heat. I reached out to Hamstra Heating and Cooling and was immediately impressed with their professionalism and care.

From the very first appointment with Larry Gorsky, the experience was seamless. Larry took the time to walk me through the entire process, explaining the different systems after carefully determining the proper size and load for our home. He wasn’t just selling a product—he genuinely cared about how we would be using the system to stay comfortable. His clear explanations and thoughtful approach made me feel completely confident in my decision.
I chose a new gas furnace and air conditioning unit, and the installation was scheduled right away—within the same week! The installation team arrived on time, worked diligently all day, and only needed my input for a couple of quick questions. By the end of the day, they had removed the old system, installed the new one, and walked me through how to use the thermostat.

The results? Absolutely amazing. The new system runs whisper-quiet with variable speeds, and the smart thermostat connects to my phone so I can control it from anywhere with internet access. The team even cleaned up so thoroughly that it looked as if they had never been there—all while I was able to continue working from my home office without interruption.

I can’t say enough about the stellar customer service and professionalism of Hamstra Heating and Cooling. They truly did everything right, from start to finish. If you’re considering service or replacement, trust me: the Hamstra team will treat you right and deliver excellence every step of the way.
THANK YOU, HAMSTRA! 👏👏👏”
