Thermostat Myths: settings that waste money

By FL-Air Heating and Cooling on November 18, 2025

Some habits that work in colder states do not work in Florida. Humidity, afternoon sun, and long shoulder seasons change the rules. These thermostat myths Florida homeowners hear all the time lead to higher bills and sticky rooms. Fix the myths below and your home will feel better without new equipment. If something still feels…

AC Maintenance

Found the problem quick, and did not charge me an arm and a leg to do it

Five star rating to a great company! Had a problem with a/c and owner Mark came out, found the problem quick, and did not charge me an arm and a leg to do it. He was very personable and explained exactly what he had to do to get me up and running again! I decided to put my system on the maintenance plan so I don’t have any surprises again! Highly recommended. Thanks, one highly satisfied customer.

5 out 5 found my new AC guy

Always worried when needing to find a honest AC or car mechanic but was lucky enough to have been referred to Mark the owner when my AC started making loud noises. He found that the shaft was slightly bent which was a cheap fix instead of being dishonest and selling me an entirely new motor. 5 out 5 found my new AC guy

I cannot say enough good things about Mark

I cannot say enough good things about Mark. We have an old unit and I was expecting to have to replace it. Mark could have told me it needed replacement and I wouldn’t have questioned it, but it was an easy, cheap fix. I will never use another AC company!!

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value

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.

Anita Akers

Very efficient at installation. Friendly and informative. Reasonable price. I'd definitely recommend them.

UPDATE: My Unit "froze up" on July 4th. Left message and they called me back at 8 am the next morning. A tech arrived before 8:30. Problem found, temporary fix made, and scheduled to be back to trace the leak this week. Very pleased with the response time and looking forward to getting the leak taken care of.

11-14-2024: Friendly, efficient service.

11-22-2024: semi-annual maintenance complete.

03-26-2025: semi-annual maintenance complete. No problems.

11-17-2025: Just had my semi-annual maintenance done. As expected, no problems and service was great.

LEE ERICKSON

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.

Austin has now been here 2 days in a row still trying to diagnose the reason I have not had AC for almost 2 weeks in this heat. I am confused since I have had 3 companies and all 3 have different answers to that question. Austin is knowledgeable and professional. I hope is is right. More important I hope he can get me AC soon.
Now I am waiting for estimates. Hope they are within my budget

Exceptional service!
Always 5-star service for past 4 years. Brandon Boudreau was by far the most thorough technician to date. Throughout the maintenance process he was informing me of current and potential issues so I could make informed decision. In addition he provided pictures for my clarity. I highly recommend this company for all of your HVAC needs. Brandon was timely and very professional, worked to ensure system was ready for the fall/winter months. Pricing is competitive, reasonable, top quality and guaranteed.

Today Brandon Boudreau with Fl-Air Heating & Cooling did 3 and a half hours of hot sweaty work in my attic removing years of growth and just nastiness from the two air handlers in my south Tampa attic. This entailed basically disassembling both handlers, removing and cleaning both blowers, cleaning electrical and all surfaces. He further installed UV lights in both units to prevent future buildups. He worked tirelessly and quietly.

I’ve used Fl-Air Heating & Cooling for years now. They are big enough to meets our needs and keep their Techs up to date, but they are still small enough to be responsive when we need them the most. Their Techs are friendly, professional and respectful and their prices are very reasonable. I wholeheartedly recommend this company.

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

D Caldwell
