Very pleased with our new hybrid system from Donmar. Excellent customer service. Best price among four quotes from local competitors. Expert installers answered our questions thoroughly and walked us through thermostat setup. Feel we're in good hands.

Very pleased to have selected Donmar as my new Heating & Cooling service provider. Everyone I've dealt with at the company has been extremely professional and helpful - from the office folks to the technicians. They provided clear communication throughout every step, showed up when they said they would, and have my new AC system ready for the summer. Special thanks to Javier, Carlos, and Ricardo.

Donmar sent Sean to troubleshoot our heat on a cold morning. He was able to get it fixed in no time and provided us with a quote for replacement since the unit was 30 years old. He took his time and answered all of my questions. No pressure sales discussion, extremely professional, courteous, and honest. The owner, Don, was extremely patient with all of my questions while I was attempting to find the best equipment and deal between 2 competitors. Don’s patience, honesty, and knowledge won me over despite paying a little more money. That extra money was well worth it when Edgar showed up to install. He was the most competent, kind, and patient contractor I have ever had in a home. I cannot compliment him and his assistant enough on the meticulous craftsmanship exhibited during the installation of a new Carrier furnace and AC unit. He took his time to make sure everything was right and we understood how to use the new system.
I would only recommend Donmar for either a HVAC repair or system replacement. Donmar is a prime example of how service companies should be. I would give them 10 stars if I could!!! Thanks again Sean, Don, and Edgar!!!!!!
