We have lost heat in the dead of winter two or three separate times - with an infant in the house.

Garret is extremely responsive on text, he has talked me through issues over the phone, and I just can't say enough good things. If you have any heating or cooling needs, he is your guy!

Joshua responded almost immediately to my request. He was kind, professional, courteous, and…read moredidn't shame me for the fact I know less than dirt about electrical work. We thought we needed a massive wiring job to get a level 2 charger installed in our garage. Joshua took time to talk on the phone about the job, asked great questions beforehand, then came out the next business day to look at the install job and give me a quote. He counselled us OUT of doing the work, and for that, I'm SO GRATEFUL. he could have easily just talked about the necessity of the job, and I wouldn't have known better. But, he's a good, ethical guy, and could appreciate our situation, and so he told us how we could make the best of our situation without massive demo and conduit, and crazy expensive wiring. And, he did it all graciously with a smile. What he got out of talking himself out of this job, is complete loyalty for any and all future jobs we'll ever need. And, I'll be telling everyone I know about him, for sure. Plus, he's a family guy, loves his wife daughter and talks about them with lots of love and pride. To me, that goes a long, long way when I think about who I want to support with my money.

Our recent annual maintenance service with Gammon's Heating & Cooling was an excellent experience,…read morethanks to technicians Tyler and Aaron. Their technical proficiency was evident throughout the visit. They serviced our nine wall units and two outdoor condensing units with care, attention to detail, and a clear commitment to doing the job correctly. Although our heat pumps were originally purchased and installed by Gammon's, this was our first full annual maintenance under their service program. We had expected the work to occur in early fall or mid‑winter, but due to a high volume of emergency heating calls, the company requested that we defer to spring. While the delay was understandable, it highlighted the importance of strong scheduling and dispatch coordination. During the visit, Tyler and Aaron identified several condensate drains that had not yet been tied into the sewer system and completed that final installation step. This proactive work likely prevented future moisture‑related damage to walls or flooring, and we are grateful for their diligence. Their problem‑solving skills, tenacity, and customer‑focused approach stood out and gave us confidence in the long‑term reliability of our equipment. We did choose to upgrade to a more comprehensive maintenance plan and look forward to having our annual service scheduled just ahead of the winter heating season. We recommend Gammon's Heating & Cooling and believe the company delivers strong technical service. One area of opportunity is dispatching and scheduling. It would be helpful for dispatch to confirm the number of units at a customer's home, understand where equipment is located, and estimate the appropriate number of technicians needed. Additionally, providing more accurate arrival windows--or proactive updates when schedules shift--would help customers avoid waiting longer than expected. Overall, the quality of the technicians' work was excellent, and with some refinements to scheduling and communication, the customer experience could be even stronger. We look forward to their handyman sheet rocker coming to patch and match wall section removed and their electrician coming to correct ground fault circuit that appears to be missing a neutral wire.

Absolutely awful…read more Since I posted my first review, we found out that two of our units were faultily installed. One led to widespread leaking (where they didn't attach the hose properly to the unit to have it drain out) that ruined our second floor ceiling and destroyed a closet. Over a year later, we started to see our living room unit leak water profusely. An agent was sent out yesterday to fix it, but lacked a ladder and said he would be back. He never was, and attempts to get someone out here again have been met with bald faced lies - "we have no record of a visit set up." These people do not install these heat pumps correctly. We have had widespread damage to our house as a result of their negligence. Do not use them EVER. Not only is their installation crappy and negligent, but their communication is faulty and suspect. Do not waste your money.

And then they ghosted me. I'm out over $1000 and I have nothing to show for it. I would not ever do business with these folks again. They are terrible.
