We used Energywise to replace our aging equipment with newer, higher efficiency systems. They took the time to listen to my concerns, educate me on the type of systems I would be getting, worked with me on installation options, took the time to come to my home multiple times prior to installation to work out the details, and despite the supply chain issues got my equipment in a timely manner.

Positive: Professionalism, Quality, Responsiveness, Value
I have used Energywise for many years. They have always been on time, sometimes a little early. As my 25 year old geothermal heat pump is showing it's age, I am having Energywise replacing it with an up to date heat pump.
Services: Installation, HVAC maintenance

Stay away. Run. Run. Run away from Energywise.
These guys installed a two zone central AC system and it has never worked properly, over $12,000 later.
The wiring job was atrocious to the extent that when the oil hot water base board heating in my house is used, the AC air handler on both zones would blow cold air wasting heat and energy. I have tried numerous times to have it corrected to no avail. I finally tried one last time to get "Mike" or "Greg" to come and correct the problem but they were a "no show" missing the appointment. No call back from the office even
