"Honest, trustworthy, and quick. My AC unit wasn’t able to keep up with the heat. Michael came out an hour after I put in the request, ran a few tests, and had it fixed in 30 minutes. He was very honest every step of the way and didn’t attempt to sell me a service or repair that I didn’t need."

"Junior and his team at Stallion came out on Labor Day weekend to get our central AC running again during 100 degree heat in Texas. They were prompt, reliable and responsive, responding to our call on a Saturday night. They came out the following morning, had it up and running again within a few hours, provided options for long term repair or replacement and saved the day!"

"From start to finish everyone I met and talked to was professional and helpful. They answered my questions and went out of their way to make sure I had the correct information and equipment I needed. I was able to talk to the owner of the company as well as the warehouse manager and service personal. The installers showed up on time and called before they arrived. They cleaned up before they left and took all the debris with them. Same for the service staff who came out the next day to make some adjustments. The installers and service people were very knowledgeable about the HVAC system knew what they had to do to get it right. Most of all they were honest besides knowing what they were doing. I have never met an HVAC company or service department that were so honest and forthright. I would recommend them to anyone. In fact, I am going to recommend them and tell my neighbors about them also. There is absolutly not question I would use them again. Dave Greer"

"July 2017 OAT +101 (F) -one of my AC units stopped working. I called them at 3:30 P.M. Wed. and they tried to to help me that same day , but of course, with the temps in the 100's they were very busy with other emergencies. They got to me first thing the next day and had my A/C up and running within a few hours. Great service! Great communication! I would definitely recommend them. They will do all my future HVAC work."

"Thomas was excellent about responding to our request for an HVAC system bid, and when chosen, they were able to schedule our installation within a couple of days. They asked our needs and made recommendations for the right equipment for our home. The crew was efficient, polite, and neat. I could not ask for more!"

"Was the fastest technician to show up to the house to fix it. He found the trouble straight away and repaired. It went and fetched apart to replace that with a new part and topped off our system. Though a service call is not free like some of the others the $75 service call fee if you do the repairs was waived. Capacitor replacement in the outside unit and a pound and a half of Freon. Our service fee was less than $200. I have had tech technicians charging me more than $200 just to replace the cap. And over $300 to top off the Freon. This company is now my favorite!"

FAQs for central a/c service or repair projects in Round Rock, TX

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
