HVAC reviews in Jacksonville, Florida

Daniel was absolutely amazing. We’re selling our home and he made sure to go the extra mile to ensure all the inspectors issues were addressed. I initially had two appointments set one for service and one for maintenance but he was able to address both, saving us time. We appreciated his attention to detail and helping us take the most cost effective route. Our buyers are pleased and I’m sure they’ll continue on with AC Designs because of it.

1/6/26. DJ was excellent. He has knowledge of our system, was friendly, helpful and even removed shoes on carpet floors. Much appreciated! He was very thoughtfull in dealing with our many questions - especially about safety concerns. He deserves the 5 STARS!!

Costs were higher than expected for replacing cut off box thus unsure about that. With service agreement, that made it a little easier to accept.

Very good company, very professional and satisfied. looking forward to call you again if needed.. thanks

The price and install were great, especially the better price than anyone else by a long way. We had some issues in installation but these were resolved before long.

I had multiple quotes and these guys were by far the cheapest, they got me on the schedule the next day, and did a great job. Thank you!

Excellent service. Most reliable and affordable,

This is a good place to get work on or replace you a/c unit.They don’t seem to have a lot of overhead (big facility, trucks, employees and advertising), so I was able to save a lot on my new unit..My son does A/C work and said they did a nice job.

Once the appointment was set. Nick and Enkiel explained everything and went to work They replaced the Air handler in the attack and the Condenser outside. Tested it afterwards well done Thank you

Excellent service, came quick, and very cheap!

Thank you very much for the fast and good service.

Great service, I got stuck with no AC on my rental, these guys were quick to respond, show up and deal with the issue all with a fair price and professionalism.

Great people that you can trust loyal and quick service I am very happy with them good people!

Great people very honest high recommended

Nick and his team did a great job and responded very quickly to come out and give me a great price with great service

Always on air recently replaced my ac unit. From my very first phone call with them I knew these guys were the real deal. They came out right away, replaced my 4 ton AC condenser on the same day, and even changed all the filters in my house at no additional charge. I highly recommend this Company.

Had a good experience with this company they came on time had professional service a lot of knowledge I will definitely use them again if I need any other HVAC services

I called a few big HVAC companies in Jax and their quotes were insane. Then I found Nick from Always On Air. He gave me a fair, honest price without the corporate markup. Professional, fast, and saved me a lot of money. Highly recommend

The technician came out to repair our heating system. He was so knowledgeable on how the whole system works and taught us how to keep maintaining it to working properly. Our heat works better than it ever did before!!!

Our heater went out on one of the coldest nights of the year. I called Always On Air AC and Niko and his crew were at my door within two hours. They diagnosed the issue quickly, had the parts on the truck, and got the heat back on before the house even got cold. Professional, fair pricing, and absolute lifesavers. Highly recommend

​I had a great experience with Always On Air AC. Niko and the team were professional, arrived on time, and fixed my unit quickly. It’s hard to find an HVAC company you can actually trust, but these guys are honest and fair with their pricing. Highly recommend!

Great service
Very fair price
And I got a quick response when I call them.
