Pete came out and did an excellent job for us installing new WI-FI thermostats so we can monitor our furnaces while we’re away. Very professional 👍

I’ve recommended ZIM Heating and Cooling to others already. We had new furnace installed recently and we are completely satisfied. Peter and Paul know their product, answered all my questions, and efficiently installed the new furnace in just a few hours. They cleaned up after the installation too.

Look no further for the best heating/AC contractors in town. Peter, Chris and Paul are extremely gifted technicians. Their responsiveness, communication and willingness to go the extra mile are unparalleled. They took exceptional care of us in the immediate aftermath of a devastating flood. Highly recommend! -CA and MA, August 2025
