High Performance Energy Solutions is a Brookfield heating and cooling company that says it repairs, replaces and installs furnaces, air conditioners, heat pumps and geothermal systems for homes and light commercial buildings. Its stated service area runs from Brookfield, Bethel and Danbury out to New Milford, Kent and Norwalk. Its BBB page is an A+. A recent Google customer needed home cooling. Dan came to the house, laid out a couple of options, got them an estimate quickly and moved up the installation date. The installation team of Kenny and Anthony arrived on time and worked through an app issue with the customer, who now has a new mini-split system. A recent Reddit commenter in r/heatpumps took about 4-5 quotes and pointed others to this company for its design and pricing. A 2025 customer said Annette guided them through the rebate process on a Mitsubishi forced hot air unit and helped them save nearly 25%. That 2025 customer also said that when their hot water went cold on a Saturday morning, a technician was at the home within hours and the glitch was fixed the same day. A 2025 customer said the crew worked at their condo for 3 days on a ductless split and cleaned everything up after themselves. Connecticut lists the S1 heating and cooling licence HTG.0401105-S1, held by Dean A Demague, as inactive.

We couldn't be happier with our experience with the HPES team and highly recommend them - We needed a home cooling solution badly - Dan came to our home, talked with us, and determined a couple of options. He got us an estimate of work quickly and was helpful in answering some questions we had. He was even able to move up our installation date. The installation team of Kenny and Anthony did a great job - arriving on time, being professional and skilled. Even patiently working through an app issue with me. Annette helped with some of our questions as well. We love our new mini-split system! Thank you HPES
I can’t recommend High Performance enough! A couple of years ago, we made a major investment in a Mitsubishi forced hot air unit. Thankfully, Annette guided us through the rebate process and helped us save nearly 25%—a huge benefit. Since then, the system’s efficiency has consistently saved us money month after month. It’s been an excellent investment, not just in the product but in choosing High Performance to install and support it. When one of the owners sadly passed away, Annette, Dan, Matt, Sam, and the entire team didn’t miss a beat. Their dedication to continuing the company’s growth and excellence has been nothing short of inspiring. Just recently, our hot water suddenly went cold during a Saturday morning shower. I hesitated to reach out on the weekend, but texted Dan and Annette anyway. To my amazement, a technician was at our home within hours, and the issue—a minor glitch—was fixed the same day. What truly sets High Performance apart is their culture. Even though they’re not all related, the team functions like a close-knit family. That spirit is reflected in their work ethic, professionalism, and genuine care for their customers. I’m incredibly grateful for everything this team does. Thank you, High Performance, for living up to your name!
Hello Dean, just wanted to tell you that the crew that worked at my condo for 3 days did an excellent job. The ductless split looks great and is working perfectly. I want to thank Matthew, Kenny, Anthony and Sam for fantastic work. They clean everything up after themselves. I am telling all my neighbors about your company.
