Atomic Ac & Heating

Atomic AC & Heating serves homeowners and businesses throughout Round Rock, Texas as a full service HVAC outfit handling both residential and commercial work. Based in nearby Hutto, the company concentrates on AC repair, system replacements, heating fixes, and maintenance plans that keep equipment running through the area's punishing summer heat and occasional cold snaps. Local customers count on them for straightforward troubleshooting and installations that match the demands of homes and larger properties in the Greater Austin region. The crew stays ready for both routine upkeep and sudden breakdowns that leave people without cooling when temperatures climb.

Branden often starts jobs by visiting the site himself to inspect problems and lay out clear options without pressure. In one case he responded within hours on a 90 degree day when a system quit right before guests arrived, sending technicians to diagnose the issue fast. Tad and Chance handled another project with steady professionalism from the first call through completion, while Jay and Tad once arrived the same afternoon a homeowner noticed no cooling, fixed the unit on site, and got everything running again before the day ended. Their bids frequently come in well below larger competitors for full replacements.

Customers keep returning because the work holds up, responses arrive quickly even on short notice, prices stay competitive, and updates flow without gaps during every visit. These strengths show up across hundreds of jobs where technicians diagnose and correct problems without delays or added costs. DIRT Score 5.0 from 369 reviews on Finds.

“We have worked with Branden and his crew for a few years - they are the best! Most recently, our AC stopped working on a 90 degree day and we had guests coming into town. Within just a couple hours of reaching out, Branden had someone at the house troubleshooting the problem. His team is very thorough, honest, and fair in their pricing. We like that they are family-owned and they seem like just generally good people as well. They are our go-to HVAC company - we trust them and recommend them to everyone.”

“Atomic AC & Heating is a no brainer option for AC replacement. The owner, Branden, personally came to my house to inspect the issues I was having then discussed my options without making me feel like I needed a degree in HVAC. His bid was half of the big brand companies in the area. My situation turned from collecting bids to emergency overnight. Branden accepted my call after hours and had a crew at my house the next morning to replace everything. The crew was not interuptive (I work from home) and the install was surprisingly fast. An inspector came out within an hour of the install crew leaving to double check everything and answer my questions.”

“The service techs, Tad and Chance, were courteous and professional. In fact, the entire process from start to finish with Atomic was highly professional. We will not hesitate to use this company again in the future.”

“I called Atomic A/C repair in the mid afternoon after turning on my system and realizing that it was not cooling. Jay and Tad from Atomic A/C came out on short notice the same day to repair our A/C system. They were able to diagnose and repair the A/C system on site while we waited. They were very conscientious and courteous. I highly recommend them and Atomic A/C repair.”

“Walter Filter Replacement. We couldn't get our filter off for our water softener so a repairman came first thing the next morning to replace it for us. Thanks for your prompt service! No charge.”
