The original installers didn’t connect the thermostat to the heating element (or whatever) so when we switched from cooling to heating, we still had cooling. They came out immediately and fixed the problem. Very satisfied.

From the initial sales contact to Installation this was a great experience. The sales and support team were professional, polite, and knowledgeable and worked with me to make sure my expectations were met. The installation team was first class, polite, experienced, focused, thoughtful, and effective at communicating and setting expectations. They treated my home as if it were their own and cleaned up thoroughly each day. The craftsmanship is excellent. The heat pump system exceeds expectations keeping us warm and comfortable even with the outdoor temperature at 17 degrees.

During a recent heat wave my ancient a/c system gave up. It was an obvious decision to replace it. What was unexpected was the effort they extended to literally re\-wire the old system so that it could limp along until the new system was installed\-\-at no charge.
