Jamar was polite and efficient. He explained what was happening with my AC and provided a temporary fix for the night. Said he'll be back tomorrow to do a permanent fix. Excellent service! Jamar is very polite and efficient. Fixed my AC in less time than anticipated. You can send him back all the time. Great role model for other employees and young men his age. Albert explained everything he did for my HVAC maintenance. He was very competent and completed the maintenance required. Overall I'm very impressed with the Southern Air technicians. They have been prompt, efficient and polite. Glad that there are still companies offering great customer service.
Response from the owner:Thank you, Jeanne, for taking the time to share your feedback. We’re glad our team was professional, explained the issue clearly, and got your AC running with a temporary solution while we schedule the permanent repair.

The installation was excellent—no mess, completely professional, and the crew worked clean and efficiently. Truly a top notch job from start to finish. Service was fast, too: I called around noon on day one, and someone was out within a couple of hours. The estimator came the next day, and by the following day the new unit was installed. It’s been running like a dream. As I said, the installation was outstanding, and I’m really enjoying the new A/C unit. Thank you again for the exceptional work. This is the second A/C unit I’ve purchased from Southern Air—the first one lasted 19 years. Their sales, installation, and service are consistently top notch, exactly what you need in this Florida heat.
Response from the owner:Thank you, Gary, for your feedback and for choosing Southern Air again. We’re glad you appreciated our professionalism and fast response, and that the installation process stayed clean and efficient with your new system running smoothly. Please call us anytime to schedule seasonal tune-ups or set up ongoing service to keep everything performing its best.

Great service. He came and I had a few problems with my system. Had some leaks he helped me figure out the area and gave some advice for repairs. I will definitely be calling him back for all of my AC work. Very friendly and knowledgeable. I would recommend southern air for everyone. Also My unit was a mini split. That I installed a few years ago. He still had no problem helping with advice.
Response from the owner:Thank you, Kirk, for taking the time to share your feedback. We’re glad we could help you track down the leaks on your mini split and provide clear repair guidance, and we appreciate your kind words about our professionalism.

07/06/26 - Dylan, today, for our routine semi-annual maintenance check. In his thorough, attention to detail, Dylan ID'd a couple electrical components that were "struggling", and destined for failure, i.e., he caught them "early" - that's called "trouble-shooting expertise"! Proactive correction is so much wiser than repairs after failure!! Another Great check-up! 01/06/26 - Routine semi-annual check-up, today! All was well, and, all went well! Robert, almost always our "Go-To" Guy, always the consummate professional, was our Guy, today; performed a thorough inspection, and routine maintenance on our two A/C systems w/ an up-check on both! We're good to go for another 6 months, or, until we're not! Southern Air is a team-oriented operation w/ a deep bench of well-trained, well-motivated, wonderful technically proficient professionals, both in the field and in the office! They like what they do, they like each other, they're having fun, and it really shows!! This is a growing business that should be, if not, already, the case study focal point of college-level business operation and administration studies, locally and around the country! 07/22/25 - Today is Tuesday. This past Friday, we enjoyed our regular semi-annual check-up, and all went well; we passed the quiz!💥 Then, sometime Saturday late afternoon/early evening, things started "warming up"! By Sunday A.M., our a/c system, a mere 2 yrs old, was failing via an oscillating blower motor on our Air Handler. Mayday! Mayday! Mayday! Temp's are rising rapidly; we're in distress! Send Help!! Jamar Witt, another stellar performer from Southern Air, arrived to discover our blower motor acting up, and was able to get it squared away ... sorta! About an hour later, after a full & frank discussion, it resumed it's irregular misbehavior, again. I brought Molly up to speed, another star "weekend warrior" @ Southern Air, and she relayed to Jamar who wrote the order; and we settled in for a couple toastie days, waiting for replacement parts! Today, our parts arrived, and Jamar just departed, ~1730, having replaced our blower motor - easy-peasy! We're cooling rapidly, now, from a heat-soaked 87°! What did we ever do before a/c? 🙄 Southern Air to our rescue, again, 24/7! 👍🇺🇲
Response from the owner:We truly appreciate you taking the time to keep sharing your experiences with us—it never goes unnoticed! Robert and Gabby are both top-notch, and we're lucky to have them on the team. Thank you for your continued trust in Southern Air. It means the world to us!

    Jamar checked the air handler as it was making a strange noise. He said it most likely was doing that because the air filter was very dirty. I changed the filter last night & we could not hear it anymore. While he was here, he checked the system out & all was running ok!
    Response from the owner:Louise, thanks for taking the time to share this. I’m glad Jamar was able to pinpoint the likely cause and that changing the filter solved the noise right away. We appreciate you choosing Southern Air, and it’s great to hear everything else checked out and is running well.
