High indoor humidity with AC running: causes and solutions

By FL-Air Heating and Cooling on September 19, 2025

If you are dealing with high indoor humidity with AC running, you are not alone. Florida homes can feel sticky even while the thermostat shows the right temperature. The issue usually comes down to airflow, runtime, controls, or a fault that keeps the system from removing enough moisture. This guide explains the common causes, safe…

I own a property in the area, I live 3 hrs away. Called Mark and he was willing to go out and inspect what the issue was. He was prompt in diagnosing the problem, quoted me a fair price and fixed the issue. Highly recommend him…

Could not ask for nicer and reasonable personnel

We had an issue on a late Saturday afternoon and they responded and helped us with our issue. We then scheduled a maintenance appt. we are now on a maintenance program that works for us. Everything was explained to us and answered all questions we had. Could not ask for nicer and reasonable personnel. Highly recommend.

I highly recommend Mark and his team for any A/C needs. Mark is not only a family friend but a true professional who always makes sure we are well taken care of every single time.

They have completed two A/C installations for us, and both were done efficiently, cleanly, and with great attention to detail. Everything was explained clearly, and the work was completed on schedule.

We also use them for regular maintenance, and they are always responsive, reliable, and thorough. It’s hard to find someone you can fully trust with your home, but Mark consistently delivers quality service and peace of mind.

If you’re looking for dependable, honest, and skilled A/C professionals, Mark and his team are the ones to call.

Response from the owner:Thanks for the fantastic review! We're happy to have served you well.

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.

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

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.
