What our customers are saying:

“I’ve been using Donovan Heat & AC for about 10 years now. They put my AC unit into my prior home and my current house as well. I’ve always been happy with both their service and prices. Any time they’re running late I get a call – I’m not sitting waiting and wondering where the service reps are! I love that they have convenient hours and call to remind me of my appt the day before. I trust the reps as well as the owners and would highly recommend them to anyone! ” read more

“David Colindris is a thorough professional, who is indisputably an expert of his trait. He is always cordial and takes the time to explain, in simple language, any issue related to the HVAC system. He is a efficient worker and a superb representative of Donovan Heat and Air. Based on his performance I recommend him, and Donovan Heat and Air services. PS. I also had the opportunity of working with Brandon Zaharie. He too is an excellent professional who painstakingly finds ways to explain complex HVAC system issues in layman’s terms. I am also extremely satisfied with his support. Sincerely; Marie “

“Called Donovan Heat & Air for service on the A/C at my grandmother’s house. They were wonderful! The repair tech who came to the house was Rod James, and not only was he knowledgeable and quickly resolved the issue with her A/C unit, but he was courteous, kind, and went out of his way to explain to my Nana exactly what had gone wrong and what he was doing to fix it. I will definitely use Donovan again, and would recommend them to anyone who needs A/C repair. Don’t forget to ask for Rod! “
