HVAC Companies St. Augustine

I was investing in a old home that never had central heat and air, Zach and his team Brandon and Mike installed central ac and the attic space for the new duct work was very small but they did all the duct work, the new vents and returns and outside unit all looks perfect. So professional and hard working..very fair price...I gave 5 stars but they deserve 50 stars. I highly, with great confidence recommend AC Heros..I will never use anyone else

Zach kept me informed every step of the way. Job started and finished on time. Techs were informative, courteous and professional. Easy interaction with updates, payment and receipts. I appreciate that Zach took the time working on a warranty issue with my 2 yr old Trane unit. Highly recommend.

~ Bish

Outstanding timely service, repaired previous companies poor work, at a great price. Not only was the work great quality but was in and out in half the estimated time. Thanks again Mr Berry

~ Dick Hedges

Jeff was able to diagnose my issues and tell me exactly what the fixes were. He gave me a few options to help prolong my old unit but just like a bandaid it was going to be temporary so I opted to replace it all together. He was able to source a unit, which is a feat in of itself right now with how parts are and get it installed quickly. He is extremely knowledgeable and will be the only person I trust with my AC needs moving forward.

~ Brian Rumbles

I had a good experience with this company. They were always on time and did what they said they were going to do. It is nice to a reliable HVAC company that I can call on.

Jeff was an absolute pleasure to work with. He saved my family by getting our AC unit back up and running. Thank you Jeff.

My AC went down on Thanksgiving Night. Someone was out Friday morning to diagnose the problem to repair. The part was ordered and they were back on Saturday to install the new coils and repair the filter on the outside unit! Very Professional and honest work! I highly recommend them for your AC needs!

~ Nicholas Biscoito

~ Evelyn Zapata

My system was making noise. I have a condo and National works on condos. Some AC companies do not. Luckily it was a very minor problem but the guys who came checked it all out. They were knowledgeable, responsible and professional. The price was good and I would use them again.

~ Linda Green

I contacted Danny from National Air and Heat regarding my AC unit freezing up and leaking. They came out same morning and Alejandro had my AC fixed and refilled with refrigerant within 30 minutes. It was a easy process from start to finish and they were very professional taking caring of the issue in a timely manner and reasonably priced. I will definitely use them going forward

~ Joel Milanes

Called them at 4pm and they were to our house by 5:30pm and fixed the problem! Pricing was fair as well. We will definitely be using them in the future 🙂

~ Jacques Mercer

Called for AC not working first thing Monday morning and the tech had the AC working quickly. Two hours after the call the technician was at my door. This is the second time I use National and I am a satisfied customer.

~ Jorge Garcia

United is “outside the bubble” regarding The Villages. They offered a quote for installing a mini-split including blown insulation for the lanai and surge protection. The job was done on time and at a cost several hundred dollars less than competition. It’s my understanding they do a good bit of installation for the Villages. I’m happy to recommend.

~ Bill H.

This company is amazing! I had a new rooftop ac installed from another company that was a nightmare. Rainwater poured into my condo for two years. I couldn’t find anyone who knew how to fix it or just didn’t want to get involved. When I called United I knew they were the one! They were amazing & the owner went above and beyond all expectations!
