William Thomas A/C & Heating

William Thomas A/C & Heating works out of San Angelo, Texas handling HVAC jobs for homes and businesses across the region. The crew handles everything from full system installs and upgrades to repairs and routine maintenance on cooling and heating units from all the major brands. San Angelo weather swings hard between brutal summer heat and winter cold snaps so locals need techs who show up ready to keep air moving and bills in check. They run as a family style operation with techs who know the local setups and common failures in these parts. Free estimates come with new unit purchases and they service both residential and commercial properties without pushing extras.

Jobs often start with a late call like the one Gerry took at nine on a Saturday night to line up parts and schedule the Monday repair when stock ran short. Troy rolls out for service calls and walks customers through every step while pointing out what failed and what got fixed on the spot. Another crew with Lyle and Mike climbed into an attic to chase what sounded like a furnace gas leak only to trace the real problem to a line further out that could have turned dangerous fast. They cover indoor air quality work and smart controls too but stick to honest diagnostics that save money on utilities instead of selling what is not needed.

Homeowners keep coming back because the work holds up under real use and the crew moves quick without inflating costs or leaving folks in the dark on what is happening. Reviews show strong marks for clean fixes that last, same day or next day response when possible, prices that stay competitive, and direct talk from the first phone call through the final walkthrough. That steady performance across dozens of calls adds up to the kind of reputation that stands out in a place where AC failures hit hard in July. DIRT Score 4.8 from 65 reviews on Finds.

“excellent service!! technician Troy was the person that came out you couldn't ask for a better tech. he was honest, explained everything that he did while showing me what he was doing. if anyone needs HVAC service, I highly recommend this company and this technician for their honesty, Integrity and excellent work!!”

“Had a great experience Troy was the tech on site was very respectful and polite and Gerry was the individual who answered the phone 9 o’clock at night on a Saturday got the parts ordered everything taken care of and fixed on Monday they would’ve had it done the same day if parts were in to nothing to do with them fast clean and polite. I had quotes up to $1500 and they got me done and out the door for $1,100 for a new blower install everything.”

“Lyle and Mike came to my house to repair what I thought was a gas leak in my furnace which is in the attic. They found nothing wrong with the furnace, but located a leak in the main gas line some distance away. I don't want to think of what could have happened if they didn't have such good hearing.”

“I can't recommend Thomas Heating and Air highly enough! Mr. Thomas genuinely cares about his customers and consistently goes above and beyond to make sure the job is done right. Joseph came out to fix my issue and not only resolved it quickly but also took extra steps to prevent future problems. Excellent service from start to finish—this company truly sets the bar!”
