"Joyce Cooling and Heating installed a new high-efficiency Lennox furnace and air conditioner. The installation looks great and was professionally completed. The furnace is working fantastic and is so quiet we can't even hear it running. We are warm and comfortable all the time and the new high-efficiency design should save us money for many years to come. The technicians answered all of my numerous questions."

"No invoice transparency at Sila Heating, Cooling, Plumbing, and Electrical. I had an appointment on February 16, 2026, to troubleshoot a no-heat issue on the second floor of my home. I was told the repair would be $1,500. Although hesitant, I agreed to proceed because I needed heat. The repair was completed, I paid $1,524.90, and the technician left. I later realized I had not been provided with an invoice, so I called the company directly at 781 438 4114. The person who answered the phone emailed me an invoice. The invoice listed an HVAC diagnostic fee of $69.00, followed by ?HYD 170,? with no price or itemized breakdown provided. I understand that professional services and parts can incur significant costs, it is unreasonable that the part alone could account for the entire charge without any supporting documentation. I respectfully requested a detailed breakdown of the invoice through multiple phone calls and emails; however, the responses I received were dismissive and failed "

"I would highly recommend them"

"PALMER GAS & OIL in Atkinson NH After 39 years with this company and at every residence since 1986, in new home commercial construction, this company is charging me $189 to remove "their" tanks from my property. I have never been late with a payment in almost 40 years. I found propane at a significantly lower rate, so I had to switch. I highly recommend Irving Oil & Gas, and say, BEWARE of Palmer Gas & Oil. expensive and greedy, no loyalty to good customers."

"Jake was very much a professional. He was on time and completed the work in the amount of time he estimated. I would recommend and hire him again. "

"Our daughter and her husband are living out of the country, temporarily. When their leasees said the furnace was blowing cold air, we wanted the repair done quickly and at a good price. Unique Indoor Comfort Heating & Cooling responded right away and came to the property the same day we called. Very professional! "

"They were A pleasure to work with. "

"Fantastic service!"

"I discovered I needed a new furnace and also a new toilet in our main floor bathroom of our house the week before Thanksgiving. I used Angi to quickly get a few company estimates and decided to go with Sanford Temperature Control/High Ground. I was very happy I did. Zach Lewis, the project manager contacted me, reviewed his estimate with me, scheduled all the work to be completed the day before Thanksgiving and followed along to be sure it was finished on schedule. He and his team did an excellent job. I highly recommend them. Thank you Sanford Temperature Control/High Ground!"

"The technician/plumber didn't get the job done at all. He ended up breaking the shower valve and ended up placing a stopper on the line to prevent water leakage. In the process, he ended up taking 5-6 hours for a job that was finished by another plumbing company in 2-3 hours. It was a waste of my money as Village Home Services billed me $560, fixed nothing and broke the valve. Furthermore, their manager/owner asked me for another $2000 for them to come back and repair the damage they created. I got this job done for $800 from another plumbing company based out of Tyngsboro. I DO NOT RECOMMEND VILLAGE SERVICES. "
