This place is FANTASTIC! Our A/C broke probably at the same time as everyone else in San Antonio and Desiree was so very helpful and friendly on the phone. They came out and fixed it within the hour and I'm so very pleased. Thank you so much! Services: A/C system maintenance, A/C system repair

We just started an annual service plan with Flo-Aire earlier this year. They came through, checked everything and told us what to watch. We had two companies out the summer before and both told us we needed a complete replacement. We were very doubtful and decided to give it another year. So glad we did because Flo-Aire didn't try to scam us into spending thousands before we needed to. Today I called in a panic as the AC drain was clogged and water was draining outside. We've had drywall damage before and wanted to catch it in time. They rushed right over and fixed the problem. I'm so very happy with Flo-Aire and especially Mario. Highly recommended!

Was sold a defective coil. Liner kept falling off, blocking the air flow, causing my unit to freeze up. After 3 repairs, this information was shared with me by one of their techs. I was then informed that I had purchased the cheaper version of the coil and that I needed to contact the manufacturer. After calling another professional, who provided a list of everything that flo air did incorrectly, flo air did fix the coil, replacing it with a brand new one. Very nice people to work with, just disappointed with their process and the way it was handled.

We contacted Flo-Aire through their website to perform maintenance on our AC and add a float switch per the recommendation of our inspector. They contacted us right away to set up a time to come out that same week. They were a little bit late but called to let us know, which we really appreciate since we have had service personnel show up late before with no notice. Steve completed the work, answered all of our questions and was very knowledgeable. Flo-Aire is a honest company that charges fair prices. I highly recommend this small business. They complete their work on time, on budget and with communication.,Y ou are in good hands with Flo-Aire!
