Frank was communicative, up beat and took the time to talk through everything. He walked me through things to look at, listen to and consider when it came to my system.

I would recommend The Furnace Guy to anyone, the value of information given as well as the complete start to finish work was far better than my expectations. He went above and beyond by sharing how I could update my system to accommodate a Smart Thermostat in the future.

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.

Long but worth it I called and scheduled an estimate for…read morework on my bathroom. The Estimator came to the door and knocked. I didn't immediately answer the door, but was a minute or two late. But went out opened the door and the estimator was running across the street. I said "Hi, I'm here." He jumped in his truck looked at me, and sat in his truck for about five minutes. I called him and he said I wasn't at the building as I stared at him and waved my arms in the air saying "I'm right here," and he said "he didn't have time to waste in his busy schedule," and drove off. I called the front desk to explain the strange behavior of their estimator Mike. and was told he had an hour to bid the job and didn't have anywhere else to be right at that moment. Fast forward five months and I call again to have an estimator come out, this time for Mini Split Heat Pumps. I spoke to the very professional lady at the front desk who told me it would be a two weeks to hear back from an estimator. I never heard back for three months. So I called again explaining I had never received a call back so she told me she would put it on the list. I called back three more times in two weeks because no one had called me back. The third time she put me immediately through to their main estimator, Good Ol' Mike. I said "hi my name is Evan." Mike Said "I know who you are and I'm never coming back to your house. You were late for our estimate the first time and I'm never coming back." He then told me that I told him that the reason I was late was because I was sick. I told him I never said that and never was sick. I've never had Covid, I just didn't answer the door immediately and you (Mike) ran away. He told me I was lieing and that "Mr. Godbout would back him up" and reiterated he would never step foot in my house. I told him don't worry about it and to have a good life. I don't know what is wrong with him. I don't know what he could reasonably have against me. But he just wasted many months of my life waiting to hear back from him for an estimate. It's clear now that he saw my address and didn't get back to me about my estimate initially because he holds some weird grudge against me. Honestly Ill never be using Godbout again because this guy is their point of contact for estimates and he is clearly unstable and I can't imagine why anyone would keep him as an employee. Everyone else I've ever spoken to there has been fine but Mike the Estimator is struggling with something.
