“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! ”

Sabrina S.

“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! “

“Donovan came out within an hour of my call that our air conditioning broke. Eddie our technician was great. He was able to diagnose and fix the problem right away. I am always so impressed with the service and professionalism of Donovan and their service people, like Eddie. From your loyal customer, Arlene Vandroff”

Debbie K.

“I have highly recommended Donovan A/C to my friends and family. David C.is an excellent A/C technician. He has serviced, cleaned and repaired my systems over the years and kept them in excellent condition, to keep my home comfortable and energy efficient. He is always careful to wear booties on his feet and keep his work neat and tidy in my home. They always give me a call ahead of time so I can meet up with them for scheduled service, and that helps me so I don’t have to wait all day for a technician.”
