Real reviews from real Donovan customers in NE Florida.
"Called Donovan Heat, Air, & Electric 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's technicians have always been on time, explained everything completely and polite. The office employees answer the phone promptly, have answers to all of your questions and if you need to talk to someone else, they get you to them with little delay. Perhaps the best customer service experience of any company I've ever patronized in 41 years of living in Jacksonville."
"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!"
