By FL-Air Heating and Cooling on July 29, 2025

When your AC is making weird noises, it is more than just an inconvenience. Strange sounds coming from your air conditioner often signal trouble inside the system. Whether it is a loose component, failing motor, or refrigerant leak, these noises are early warnings that something needs attention. Understanding what the different sounds mean can help…

Very professional and prompt.

Mark and his crew were great to work with. Very professional and prompt. His pricing is fair, and he takes great pride in his work. We would gladly endorse his services and can’t be more happy with his repairs and all his help.

AC repairs can be costly, but I believe Mark gave me a competitive quote without doing unneeded repairs.

Mark was very helpful! He gave my unit a prompt diagnosis and took the time to walk me through each step so that I knew exactly what the condition of my unit was. AC repairs can be costly, but I believe Mark gave me a competitive quote without doing unneeded repairs.

This a 2nd update (January 2026) to my earlier reviews. HVAC tech Ryan came to my home just a day or two after FL-Air merged with Veteran Air. My experience with Ryan, who came for routine maintenance on the HVAC system in my home. I was appreciated Ryan's manner which was friendly and professional. I was particularly impressed with his ability to explain to me his findings and answer my questions about the inspection and maintenance he provided. Excellent service.

This is an update (July 2025) to my initial review of FL-AIR Heating & Cooling almost a year ago. HVAC tech Brandt came to my home yesterday to perform routine maintenance on our air handler. He arrived on time. His manner was courteous and professional. Brandt's work was both careful and thorough from start to finish.

During a previous appointment Brandt noticed that the insulation on the inside of the handler's front panel was peeling off. He spray-glued it back into place and anchored the perimeter with a strong adhesive tape. I appreciate that he pays attention to the details.

Before leaving, Brandt gave me a brief verbal summary of all the items he had checked and serviced. In a nutshell, my experience with FL-Air has been excellent. I give them my highest recommendation.

We’ve been with them for awhile and they have always provided great service. Yesterday was the first time we needed to call them over a weekend and their response was nothing less than outstanding. Within 90 minutes of calling they had a technician at the house diagnosing and fixing the issue. From the rep on the phone to the technician onsite, they made us feel like a valued customer.

Response from the owner:Hi, Michael. We are thrilled to learn that you had a positive experience with us!

I have now hired FLheating and air for three separate occasions. Twice for duct related issues, and most recently for a very complicated upgrade of a very old AC unit.

Their technicians and staff, in particular Brandon have always been consummate professionals. They always gave all reasonable options and what to expect in uncertain areas. Fortunately, their experience and expertise is evident when everything goes perfectly well.

They clearly take tremendous pride in their work, and I would not hesitate to hire them again or refer them to anyone I know.

Response from the owner:Hi, George. Thank you so much for leaving us a stellar review!

What a great HAVAC company and service tech. This is the second time I have used them for a service call and they are so honest and efficient with their scheduling, my issue turned out to be minor one and was fixed immediately. I have since signed up for an annual service and maintenance contract which is a great deal.

Response from the owner:Hi, Kirk. Thanks for taking the time to share your positive experience. We truly appreciate it!

Mark Lang and his crew are truly the best professional HVAC company I have dealt with in decades. I particularly enjoyed Brandt the tech and will request him as my primary technician. He was kind, thoughtful and really efficient. totally transparent. SO grateful for FL-Air Heating & Cooling! and again they just keep ringing the bell! Brandt is terrific. He came over today and did a wonderful thing and I must say coral spelled KORAL is a fantastic receptionist. It’s very responsive that the entire company is a direct reflection of their owner Mark Lang, who is absolutely incredible: high integrity, trustworthy, and good employees. I endorse this company 1,000,000%.

Brandt was great. He explained everything and did not try to sell me on service or parts that I did not need. He was diligent and thorough and left his area of work neat and clean. Refreshing to have someone that cares. He even showed before and after pictures of his work. My ac guy retired and as a long time realtor it is good to have someone I can feel good about referring to others again.

In my opinion the company did a great service for me. After I have called and talked with them they sent a technician out and he was here right on time that we agreed upon. He was professional in his duties diagnosing the problem we had with our air conditioning equipment. The parts were ordered, they called and let me know the parts were in and scheduled the time for the technician to come out, the technicians was here on the agreed time. Brandon was our technician who did the diagnosed and did the work installing our parts, he worked very professional steady, and finished in a timely manner. I feel the company should be very proud of Brandon to represent their company the way he did very professional. Their prices were reasonable. I would definitely highly recommend their company. I would definitely use them in the future. I also feel that they have great service plans I would definitely recommend those also.

I keep using this company due to several reasons, they are always prompt either when I have a problem with a/c or when I need maintenance. Next is important to me as this is a trustworthy company that has always been honest with my a/c needs.One more thing is the technicians are the best, they explain and educate you on the a/c, companies don’t take the time for that anymore but this company does.

Response from the owner:Hi, Tina. Your feedback is highly appreciated. Thank you for the review!
