HVAC reviews in Jacksonville, Florida

I had a very positive experience using HVAC technician Quenton Martel from David Gray. He was professional, easy going, provided great education about what he was doing and what his recommendations were, and was a really nice technician to work with. I highly recommend both this company and this technician when needed. Great job, thank you!

My A/C recently ceased to function properly. I found David Grey Heating & Air on the net and gave them a call. The troubleshooting technician that was sent, Hamid, was very polite, knowledgeable, and honest with me that my A/C had seen its best days. After discussing what the best options were it was time to replace.
Nico and Bryan were sent out to install the new A/C system. These two gentlemen were AWESOME. Very professional, courteous and answered all of my questions.
I am very happy and grateful that I chose David Grey Heating & Air. I have called on other companies over the years for A/C work, David Grey is second to none!
Outstanding Work!!!

Gabriel and Jon were phenomenal. They provided 5 star service. The explained and demonstrated everything to us. They place everything neatly back they way they found it. Kudos to not leaving any trash behind. They were very professional and proficient. Job well done. Thanks 👏👏👏👏👏

These people are not Fessionals. They are Professionals! I was visited today by Adam to do a hot water heater flush. The woman who I first spoke to, I don't know her name, was very polite and informing. She also told me only David Gray vehicles are used so don't be taken by anybody else. This is very calming news in a world where A.I. can help criminals in ways I can think of. She told me Adam would be my tech and he'll be here today.
Adam shows up on time and gentlemanly. He was a terrific blend of informative, kind, and professional. He told me what he was doing, what he hoped will be and what he can do if things go awry. He had all the tools and moved with certainty. I feel safe that he'd take good care of my hot water heater. The man was fast and he assured me my water heater was cared for - based on how smooth things went. I asked him if I could take a picture of him working. I wanted to shine light on him doing a great job. He also answered my questions about if they sell hot water heaters in case I need to get a new one in the future. He laid out what they can do, that they'll take the old one out and bring in the new one. Everything. I'm very pleased with my experience.

I recently had the pleasure of meeting with the HVAC Technicians from David Gray Heating and Air Conditioning as part of my Comfort Club membership. They performed a thorough diagnostic on my A/C unit, and I was very impressed with their professionalism and attention to detail. The technicians explained everything clearly and made sure my system was running efficiently. I appreciate their dedication to quality service and would highly recommend David Gray Heating and Air Conditioning to anyone in need of HVAC services!

Called David Gray for an electrical issue as my Pep-Tank wasn’t functioning.
FGUA came out first to determine it was a problem with power to the control panel.
A rusted wire at the breaker was the issue.
The tech (Adam) was great and fixed the problem.
Here’s the bad news:
Their price to fix the problem was north of $1,500. I was a bit shocked as I was told that their labor rate was $400/hr. And that he needed to drive to the supply house to get the replacement part during which time the $400/hr rate would also apply.
With the urgency of the sewer backing up in the house, I made the mistake of approving the quote as he left for the supply house. In the meantime, I did some research and learned that the average labor rate for a licensed electrician in Florida is $75/hr.
Turns out that David Gray, once a family owned business, was recently bought out by a larger firm which then increased the rates/prices - Lesson Learned!!
Hope that sharing this experience prevents others from getting hosed like me!
It was a simple repair that any licensed electrician could have done for a small fraction of the $1,500+ that I paid.

Next day follow up:
Received detailed invoice (photo attached)….they charged $223.88 for a 30amp breaker switch- almost a 1000% mark-up for this $30 part!
How does a company like this stay in business?

I called David Grey for a lighting fixture replacement 2 weeks ago. The technician came out (Tyler) and gave quotes for Everything BUT what I needed him for. I called David Grey back and asked for a quote for just the outside light and was told I would get a call back during the week from a manager for this quote. After 1 week, still no call or email quote. I called AGAIN explaining the same issue and what I needed. I was told no one was in the office to give quotes and told me to call the main number until someone answered.
Longer story short. I fixed the light with my 13 year olds help.
I don't understand the issue with David Grey during this time, but they were great for prior electrical needs. For this I paid for a quote I never recieved. It was a Waist of money and headache.
Right now, I Don't see myself ever using them again.

What a great experience with David Gray Services! From the technology to sales, from Staff office communications to Texting and even sending a photo of who was coming out to my home for Installation of both inside and outside HVAC Systems. Nico and John arrived on time and worked the entire day with efficiency and professionalism. They are both friendly, knowledgeable and patient. Nico really took the time to answer the ton of questions I had learning the upgraded systems. He is so kind and I thank him for his patience. Both installers respected my property and me and cleaned up when the work was done. I appreciated Charlie in the beginning when he made several calls into the office to confirm options to move forward. I appreciated Melissa, who answered my questions regarding the Club Membership therein and what that entailed moving forward. Thank you to Tom, who was generous to explain the differences regarding Variable systems to my husband. I look forward to lower utility bills with the better models! Good job to everyone on the Team and I will recommend you to everyone I know. Kudos on all departments from Sales - Service - Installation - Administration

Eric came out on time, he was very courteous and knowledgeable, Not only did he do repairs on both units, he also educated me on my HVAC System. I will definitely recommend to all of my friends and clients. This was a stellar experience.

As has been my experience with United in the past, service was prompt, professional, and courteous. I have asked my home warranty company to send heating and air conditioning repair folks only from United and not from any other company.

Our service technician Diontae was very polite and professional and explained step by step. He listened to our concerns and was able to get our AC check and made sure the air flow was flowing in the house correctly. Thank you 😊

Came to United air/Temp via American home shield warranty. I've had several warranty claims on various units so have a good basis of quality of uniteds work and priorities.

Eric, usually my technician, is always professional and on time. However United themselves do not carry parts and need to go through an ordering process that typically takes 5-10 business days. This has happened several times resulting with WEEKS of no AC service in summer in Florida.
On top of that, United won't let you schedule the install of the part until it is delivered. Potentially resulting in even further delays by multiple days.

This has happened to me multiple times already.

Getting you up and running quickly in the summer just doesn't seem to be a priority to them. ;(

UPDATE: 7/11/25:
After calling the number provided by their response to this review, and waiting for the part to be delivered... technician came by today to inform me that United had ordered the WRONG PART. And we would likely have to wait ANOTHER week w/ no A/C - this in Florida in June/July.
United's response - we will email our escalation department as that is the fastest way to get this resolved.
I would think an escalation would warrant a phone call and actuall discussion. I guess not. Will follow up on this review w/ actual timelines and when this does get resolved.

The technician was very helpful and knowledgeable.

The company overall has been very good. The service tax are always very polite and seem very knowledgeable in their work. We bought our unit from them and it was a little pricey. But it's a good unit and the workmanship was really good. Overall we're happy.

Such a great company. Recommend their full service agreement rather than home warranty for expedited repairs and preventative maintenance. Every technician we have interacted with has been thoughtful and kind.

The technician Eric Almonte did a great job on a/c maintenance...thanks so much.

The service tech was timely, friendly and knowledgeable. I’ve had my unit serviced for the past 3 years and it has always been a pleasurable experience. Definitely my go to company for a/c maintenance.

Your man was an hour late for the 9am appointment Thursday. I have a leaf cover on the condenser unit he put it back on upside down. The air handler is in the attic he did not have a ladder.I had to go get mine for him to use He said he would email me my receipt.I still have not received one.

THE SERVICE PROVIDER DID A GREAT JOB IN DIAGNOSING OUR PROBLEMS & GOT OUR UNITS UP & OPERATIONAL, PENDING PARTS THAT NEEDED TO BE ORDERED

Eric was great. He came early which was perfect for me working from home. He was very polite and informative. Took his time to make sure everything was working correctly. Provided great feed back and just overall great customer service.

Tech was on time , was professional and polite. He explained what had cause the problem and what to do to avoid it from happening again.
