The outdoor unit ended up having a manufacturer issue. MRCOOL sent a replacement condenser, and Downeast came back out to install the new unit and make sure everything was working correctly. They took the time to troubleshoot the problem and handled the replacement without any hassle. The guys who came out were great and the work was done professionally. It is good to see a company stand behind their installation and follow through when something needs to be fixed. I would recommend them.

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.

Anyway, I saw the poor reviews on Yelp, but ignored them and figured only frustrated people usually leave reviews. Well, I have become one of those frustrated people. Muller didn't show up at the time we had scheduled. Same issue. Someone else had noted previously. I called an hour later, no answer, left a message. Called an hour after that and got to speak to someone. They said they had been trying to contact me and that they had something else come up and couldn't make the appointment. It's interesting though because I had no emails, texts or phone calls from them . They said they could book another appointment for me, but that was another three weeks out. I won't contact them again for anything, and I will not recommend them to any friends, but rather just the opposite. Disappointing. Paul H in Gorham ME
