“After 25 years, our HVAC finally stopped cooling. We tried to get by with just adding Freon but the tech (Steve) informed us it needed more than that and it would be expensive. He gave us an estimate for a new system and then made sure there was a smooth hand-off to the installation team. He was very honest and courteous and even called back to make sure everything was going well after the installation.

The installation team (Rich, Alex and Yaw) showed up on time and worked hard all day to install our new system. They covered the floor, wore booties inside and cleaned up after the installation was complete. The team took the time to explain how the systems (heat pump, air handler, humidifier and wireless thermostat) worked. The hot weather returned a couple days after the install and we were nice and cool. The recent cold snap has also given us the opportunity to try out the heat and it sure is much warmer than our old system. Very happy with the products and the DM Select team. Thank you!”
