Harry's Heat Pumps does what the name says: it installs and services heat pumps around Windham, and it holds 5 stars across 15 Google ratings. The company describes itself as located in the greater Windham area and says it has over 10 years of experience installing and servicing all major brand heat pumps. It says it offers free estimates. A local news site, business.thewindhameagle.com, has described it as based in Windham and helping home and business owners save money through efficient heating and cooling systems. A customer said Harry installed three Mitsubishi heat pumps for them while removing an entire Daikin system, put in by another installer seven years earlier, that had failed. That customer got quotes from two other companies and said the price, the workmanship and the whole experience could not have been better, adding that the job was neat and clean. A customer who hired Harry for a Mitsubishi heat pump installation in their home praised him from the initial consultation and estimate through project completion, and singled out his knowledge and pricing. A customer said Harry and his team installed their Daikin heat pumps five years ago and that they have them do regular maintenance every year. A customer said Harry showed up right on time, got right to work, explained the continued maintenance for their heat pump and scheduled an appointment for next year.

Harry and his team installed our Daikin heat pumps 5 years ago. I have them do regular maintenance every year. He and his team are great. Professional, knowledgeable, and reliable. Definitely our go to people for service!
Prompt, professional, knowledgeable. Harry showed up right on time and got right to work. He explained the continued maintenance for our heat pump and scheduled an appt for next year! Highly recommend.
I wanted to write a review because of the great experience with Harry's Heat Pumps. Harry recently(8/2026) installed 3 Mitsubishi heat pumps for us, while having to remove an entire Daikin system that had failed miserably, which was installed by another installer 7 years ago. Right from the start it was a great experience. I got quotes from 2 other companies, but the price, workmanship and really the entire experience could not have been better. I very highly recommend Harry and there is a reason that he is so highly rated. The job was so neat, clean and very well done that are thrilled that Harry was able to get us into his schedule. If you are considering heat pumps, don't even look anywhere else. I also highly recommend Mitsubishi. They are the best. If you want a professional, well done job, hire Harry. I had not met Harry before this job, but am glad that I did. Read the reviews and they tell the story. Harry's Heat Pumps is the best in the business, hands down. Harry, if you see this, thanks for a job well done!!
10/10 would recommend. Both the service and products provided were high quality.
Harry came highly recommended to us and did not disappoint from initial consultation, estimate and project completion of the installation of the Mitsubishi heat pump in our home. His knowledge & pricing are second to none.
