I have been using Comfort Air services for more than 15 years and their service is always honest, of quality, timely, professional, and fairly priced. Today, I used their service on an emergency and Jesus and Clint were exceptional in all aspects. I always recommend Comfort Air to friends, family, and colleges.

Thomas and Nathan stomped through a block of muddy streets to get to my house to fix my AC almost an hour after I found the water puddling in my house. Our street outside was too muddy to drive on but that didn’t stop them. They were fast, polite and professional. I couldn’t have asked for better service and I’m grateful to them.

As a property manager in San Antonio, I’ve worked with a lot of HVAC vendors, and Comfort Air is simply the best. Adam Schmidt is incredibly responsive, knowledgeable, and always available when something comes up. Their pricing is very competitive, and their team is consistently quick and efficient. I’m genuinely grateful to have a partner like Comfort Air and a pro like Adam I can count on. Highly recommend.

Saturday morning of the Memorial Day weekend we had a plumbing problem. The sewer line was clogged and water was backing up ... Nasty! I called Primo Plumbing and they had a plumber at my home in about 90 minutes. He put a long snake down the line and got rid of the clog. Sunday morning the same thing happened again. I called Primo Plumbing and a plumber was at the house within one hour. He used the snake again and this time cleared it well. We checked the sewer flow and it is draining well. The response on a weekend is one thing but to have that quick a response on a holiday weekend is superb. I commend them greatly. September 2026, We use Comfort Air/Primo plumbing at 3 locations. 2 are residential and 1 is commercial. 2 days ago we had problems at all 3 locations. We called Comfort air/Primo plumbing and they have already repaired 2 of the locations. The 3rd location is needing a new A/C unit. They are preparing the estimate for us. We trust them so much that we are not even pricing the new A/C elsewhere. They really know how to take care of their customers.

I truly appreciate the exceptional level of service I have received from this company Over the years, I have always been impressed with their honest work and upfront quotes. I have even sent their team to my mother's home for second opinions because I know I can trust them to provide honest inspections compared to other companies. In my recent case, my technician, Luis M., was fantastic. He didn't rush the process, diagnosed the issue, and successfully fixed a joint that had been left unsoldered. I really appreciate how thoroughly he took care of the problem. Highly recommend!

Last week our AC went out and Comfort Air, who we've been using for over 5 years came out ASAP and got us up and running. We have always been impressed with the quality of technicians they have but this last guy, Fernando was exceptional. He was courteous and professional and very knowledgeable. He showed pride in his craftsmanship. Thank you Comfort Air and thank you Fernando.
