Capitol Air Conditioning Services Llc

Capitol Air Conditioning Services Llc works out of Round Rock, Texas, where they handle HVAC repairs, replacements, and maintenance for homes facing the area's hot summers and occasional cold snaps. Owner Martin Davis leads the crew and often shows up on jobs himself, bringing in techs like Derek and Christian for everything from quick fixes to full system overhauls. Homeowners in the area call them when units break down or when safety issues like gas leaks pop up, since the company sticks to straightforward diagnostics and solid repairs without dragging things out.

Martin Davis rolled out a full inspection and proposal when one customer needed an old air conditioner swapped, catching extra improvements along the way and finishing the install with his team. Derek squeezed in an emergency visit after another tech missed a leak, sealed it right there, and got the system running again before adding tips to keep it going. Christian showed up fast on a maintenance call, swapped a bad capacitor, handled the service in under an hour, and spotted a loose furnace exhaust pipe that he fixed to stop a carbon monoxide risk. Martin also spent hours checking every gas appliance after repeated detector alerts, sorting out a setup that had stumped others and making sure nothing dangerous slipped through.

Customers keep coming back because the crew shows up when they say they will, explains what needs fixing in plain terms, and sticks around until the job holds up. Speed stands out when units fail in the heat, while the quality of the work prevents repeat calls on leaks or electrical parts. Prices stay reasonable for the level of detail, and follow-up calls or extra checks on maintenance build trust over time. DIRT Score 5.0 from 88 reviews on Finds.

“My old system needed to be replaced & I was referred to Capitol A/C by a friend. Martin Davis came out & provided a very thorough check of my situation, and gave me a detailed proposal, which included several improvements. The team (which included Martin) that arrived to install my new air conditioner/heat pump were all very polite & professional. I highly recommend Capitol Air Conditioning from the standpoint of their knowledge, pricing, and quality of work. Look forward to working with them from this point forward for my a/c needs.”

“They were able to fit me in when my AC went out. Derek called me and was able to come earlier. He was able to find a leak that 2 other companies did not find, took care of it on the spot and we were up and running in no time! He also followed up with suggestions to help maintain our system and their rate with very very reasonable! My new AC company!”

“I had a carbon monoxide detector alert several times. It was a complicated situation that I literally would not have survived without the expert help of the owner Martin Davis. First, he and his crew came out and inspected all my gas appliances. He took several hours to complete the inspections, being very thorough. He suggested a 2nd opinion from the propane guys and worked with them on a solution. That is indeed rare to put a solution ahead of ego. Ultimately, they found an issue with the heat exchanger. He guided me through a very complicated warranty issue and defended my warranty rights with several difficult manufacturers. Of course, his team then expertly fixed the issue. He returned with his tester to confirm all was resolved and found a 2nd problem with the water heater. That 2nd visit truly shows the care and dedication he and his team deliver for their clients. There are many AC guys out there, the difficulty is finding someone who cares and will go the extra mile (and then come back) to make sure my family was safe and ac unit was performing. Doesn't get better than that!”

“My cousin, Elisa, recommended Capital AC because the did great work for her. Christian arrived within an hour of my call. He replaced the capacitor and completed all maintenance in less than an hour. He also located a loose exhaust pipe on the furnace and repaired that, preventing a dangerous carbon monoxide leak. This company has honest, caring employees and the bill was lower that I expected. I cannot say enough great things about them! Thank you, Christian, for saving the day!”

“I was incredibly delighted with the service by Mason the technician who came to my home. He was extremely thorough and gave me a 20 minute phone call about what was wrong and what he fixed. I thought the price was very reasonable for the time spent and the level of detail. I highly recommend this company!!!”
