Outdoor AC Unit Not Running: Quick Fixes and When to Call

By FL-Air Heating and Cooling on October 21, 2025

You hear the indoor fan, but the house is not getting cool, and the temperature keeps climbing. Walk outside, and the condenser is silent. When the outdoor AC unit is not running problem shows up, the system is only moving indoor air around. No heat is leaving the home, so rooms feel stale and warm…

AC Repair

Quickly diagnosed the problem and had my A/C working within about an hour.

Ryan came out to get my A/C working again after being without air for a couple of days. He actually beat me to my house and waited patiently for me to get there. He quickly diagnosed the problem and had my A/C working within about an hour. Highly recommend.

What I witnessed then was the most masterful, well mannered, highly disciplined crew of people come into our home to do their work.

Mark Lang and his crew are truly the best professional HVAC company I have dealt with in decades. I have owned homes up and down the east coast and have had to deal with HVAC issues at all of them. We knew our system was at its end of life and finally it happened. The evaporator on our 3rd story finally bit the dust. I had already pretty much made up my mind to go with another highly reputable firm when I reached out to Mark to see if he was interested in what I had going with a very competitive bidding war. He said yes and I welcomed him out. No only did he send his estimate in less than a day, what I saw for good brand units was incredibly aggressive. I picked apart his proposal from top to bottom, he was very clear that there would be no hidden costs and that his estimate was his word. I went with a new company. What I witnessed then was the most masterful, well mannered, highly disciplined crew of people come into our home to do their work. The guys are buttoned down and know exactly what they are doing. They replaced two zones, air handlers, hurricane package, sensors with safety off switches, they tore out our old wooden platform which one company said, “Oh you should just keep this, you don’t need air braces”. I went with the air braces for aesthetics as well as more stability. Mark then showed me the platform they removed. It was beginning to rot and I made the correct choice. There are all kinds of HVAC companies out there. As far as I am concerned, FL-AIR is my company choice for ever.

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.

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.

Tina Pennino

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!

Kirk “Captain Kirk” Diaz

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.

Echo EliteTeam

Always the best AC company. When you have a problem with your AC and you call Florida Air, they will be there to take care of it. I will never use another AC company. If I could give 100 stars i would.

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.

Mary Ellen Kirby

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

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