Recommended Customer Reviews

Donovan bought out Superior air & heating, where I was a 20 year customer . Our A/C is under warranty and the fan motor gave out. I called them and they quoted me $540. I told it was under warranty and they told me that was the labor to install. I went out and bought a replacement fan motor with the capacitor for $150 and installed myself. It took me, an unprofessional, less than 30 minutes to install. There customer service is poor and we won't be calling on them again.

Donovan Air installed our mini split today on our guest bedroom. This bedroom's exterior wall faces west and the afternoon sun does a job on that room so that it causes the main AC to run more than necessary. These units are amazingly quiet and definitely helps maintain a more balanced interior climate now.
Cory and company were a pleasure to have on site. They were on time, very professional, courteous and left the job site clean as they found it. Brandon in sales gave us a fair and reasonable price. There are many AC companies advertising and it's hard to choose which one to go with. Having a reliable HVAC company to turn to is very important in Florida. I recommend Donovan Heat and Air without reservation.

I am extremely satisfied with the HVAC work that has been done on our home. The responsiveness of the company and of the entire team was amazing. Preston recently completed a project in our home and was absolutely wonderful to work with. He was very detailed with all explanations of work and had a positive, determined demeanor throughout the project. Dillon also provided very thorough explanations and contributed in an excellent manner to all work that was completed. Working with Preston and the entire team has been a great experience and we look forward to continuing to work with Donovan Air for future work on our home as well. 10/10 stars for Donovan Heat, Air & Electric! Thank you!

The previous owner switched to Donovan Heat & Air as the maintenance provider a few years prior to me purchasing the house. I know because I rented my home before the owner offered to sell it to me.
I just renewed my second year maintenance plan and have been pleased with their work and professional employees. Today, Ross came out and provided my Spring maintenance. He took the time to explain things about my heating/ac unit and the brand the last owner purchased.
The work took about one hour, and I'm provided an update on how my equipment is operating. This gives me peace of mind that my unit will not go out anytime soon. But if it does, I have priority when I call for a repair and will receive a discount on any needed work. This also extends to plumbing or electrical issues.
If you do not have a hvac maintenance plan, you are missing out. They may find something in one of the semiannual evaluations that could save your unit or at least extend its life. Give them a call or schedule an appointment online.

My ac coils started to freeze up so the ac was not cooling the house. I called Donovan and within two days, the problem was solved. The technician James who corrected the problem, was knowledgeable and respectful of my property. I'm so happy I am now using this company.
Thank You Donovan AC

My mom and I liked the 2-day duct work performed by Donovan Heat & Air. Were blessed to have 5 guys on first day when we were expecting 4 guys and were blessed to have 4 guys on second day of which could have been done with 2 guys instead to finish up. Call this amazing efficiency at the time of opportunity.

In a sentence....Great service, on time, came out same day, the technician, Hobart, checked my warranty without me asking and found it was still under warranty, he fixed it, and I didn't have to pay a thing which was a nice surprise.

I have not personally used Donovan's, but will NOT use them when I need A/C help. I have constantly seen their employees in company vehicles act and drive like complete a-holes. Today took the cake. Was driving on Palm Valley Road, when a sales truck I'm guessing was to busy texting/on his phone to notice the light had changed. After 2 other cars passed I honked. He continued to look down at his phone in his lap. While trying to get around him to turn onto nocatee center, he then slowed down, and then flipped me off after I was able to get around. That response because I honked 1 time. He looked to be a thinner gentleman with a dark hat on and sunglasses.
Earlier in the week, one of their service vans was finally pulled over by police as he had been speeding and driving like he didn't have a care in the world.
These two most recent encounters show that the people they have working for them are not about customer service, and disregard anyone around them. I would hate to trust them with my needs for service as I think these actions show a lot about someone. Do whatever you want, as long as you don't get caught.

i recently had routine service on my air handler. I was fortunate to have Eric service my unit. He by far one of best very knowledgeable and very engaging. I have been a customer of this company since 2014 . I found that this company is also into plumbing and electrical, and I will possibility use their services based on my prior experiences.

I had Donovan service my ac unit and they replaced a capacitor. They charged me $400.00 to replace it. I went on line to find the exact capacitor for $89.00 . I went to there office and the mgr agreed to refund me $200.00. I will never use Donavan again . I have shared all this info with my association neighbors about the company rip off. Do not use this company unless. ???????
