“I can only give you 5 stars here, but I give you 100 stars. Contacting several HVAC Companies, I decide to use Carnes And Sons, a family-owned company, honest recommendations that met my needs (no hard sales) for the installation of new AC & Heating System. Clint and sons arrived at the appointed time, very professional, and courteous from the first correspondent to the finishing of the job.

The crew was also just as professional, knowledgeable and courteous and arrived on Monday and installed the system in 4 ½ hours. But ran into a problem with my thermostat connections (original unit over 20+ year old, so was the wiring), but left me with air up and running for the night. Returned the next day to replace wiring in the attic. A late decision on my part to upgrade the thermostat, so Clint came today to install it.

Carnes and Sons and his crew (thank you guys) are hands down one of the best contractors I've ever had to work for me in San Antonio. You get the best price in town and the superior service second to none. They are NOW my first choice for all HVAC repairs."

“I had my AC go out and I called Clint as he had installed the unit about 3 yrs ago and had given us great service. It ended up not being the AC that was bad, but my wiring from 1977 was done. He called his electrician and the electrician had a crew out the next morning and replaced wiring and the panels. Clint did not charge me for coming out.

He came out after hours and spent 30-45 minutes figuring out what was wrong,. he refused to take a payment from me. He also had shown up the day before he was scheduled as he knew we were without AC in these triple digit temperatures we were having. That was great customer and he has my business going forward. When he installed my AC 3 yrs ago he saved me $3500-$4000 on what other companies were quoting me. Good guy and good family.”

“Top 3 takeaways after using Carne & Sons to replace our interior and exterior central air units: #1 The knowledge from the first call was helpful in not wasting money because I didn’t know what I needed. I was on the phone with the owner and he was able to give direction as well as offered a free consultation. (other companies were going to charge $85 just to come out) #2 In person he was informative but low pressure with making a decision. Negotiations were fair and I got a great deal. #3 It only took 24 hours from the time I said yes, I want a new unit to the time that they were able to remove my old unit and replace it with a new one. I highly recommend using their services. Great service and great people".
