★★★★★ 5.0 Adam Johnston · May 2025

Fantastic experience with Great Mills. They installed a new high-efficiency Amana unit at a price that was substantially better than competing quotes for similar units. The service team was fast, professional, and punctual. I needed a quick adjustment within a couple of weeks and they sent a tech out, same-day, without any resistance. I would happily use them again.

Great Mills Heating and Air just installed my hot water heater and installed my hvac system 4 years ago. I have been impressed with them both times. Their service is friendly, efficient, timely, and they are reasonably priced. I will use them again the next time I have a need for one of their services. I highly recommend them!

The team at GMH&A/C always do a fantastic job. They're on time for appointments and communicate what needs to be done and what we can expect in regards to time-frame, price and performance. Always fair pricing and quick service whether its routine maintenance or emergency service.

★★★★★ 5.0 Ramon “Ray” Badia · Feb 2025

I have been using Great Mills (GM) Heating and AC since 2000 and can sincerely state that they have been the very best at all they do. There have been occasions when i used other providers but was not satisfied with how they operated and the work they did. My reason for using another provider was due to me having an insurance that covers the systems in my home. my experience has been that it's best to pay GM separately and receive better service than to use my insurance for the two Systems in my home. GM installed a Geothermal system in my house years ago and they did a great job. I had three separate providers give me estimates for the Geothermal. Three of them came in at a much higher cost estimate. Some said they had to put up a pump-house. GM did the job for less without a pump

★★★★★ 5.0 Ted Turner · Apr 2025

We have been doing business with Great Mills Heating & A.C. since we built our house in 1997. They are professional, polite, couteous, and reasonably priced. I see HVAC trucks from the other guys parked at the same houses multiple times, and I have to wonder, what are they doing so frequently? We're on a 2x a year service plan which as worked very well for us. We highly recommend Great Mills Heating & A.C. Ted & Marci Turner
