We've been using Pro-Tech Air Conditioning and Heating since we moved here three years ago. They are very professional and their work has always been great. They send a technician every six months to check our systems. Even though there are a number of technicians with Pro-Tech, they send the same guy to us every time. Brandon is our technician. It's nice that we know him and he knows us. He also installed the new furnace and water heater and did a great job. I highly recommend Pro-Tech Air Conditioning and Heating.
