Cool Kids AC

Cool Kids AC operates out of Round Rock, Texas, and focuses on HVAC work across the area including Georgetown, Cedar Park, Pflugerville, and Hutto. They handle air conditioning repairs, full system installations and replacements, heater and furnace fixes, plus commercial HVAC jobs. The crew also takes on plumbing tasks like water heater replacements and relocations when those come up during HVAC calls. Homeowners in the hot Texas climate call them for both emergency fixes and planned upgrades on older homes that need reliable cooling and heating systems year after year.

They send technicians like JJ, Darren, and Misael out on jobs that range from quick diagnostics to complete replacements. One customer needed a water heater swapped out and moved from under the AC unit into the garage because the original setup was too small for a three bedroom house, and the crew handled the relocation at a lower price than other quotes. Another homeowner got an estimate from Darren and saw the full HVAC install finished by Misael in just four days. JJ has diagnosed weak cooling problems in under thirty minutes, tracked down parts the same day, and kept older units running through minor repairs before leading a full system changeout on a twenty three year old home.

Customers keep coming back because the work holds up, the crews show up fast, the prices stay reasonable, and updates come through clearly from start to finish. Reviews highlight solid results on both small repairs and big installations without unnecessary delays or added costs. That consistent performance across hundreds of calls in the Round Rock area builds trust for homeowners who need their HVAC systems fixed right the first time.

“I had cool kids replace my water heater. However many years ago, whoever built the house thought that under the AC was a good idea, and they put in this tiny one for a 3Bedroom/2Bath house, so it was time to replace it and relocate it to the garage. Most reasonable pricing of all the quotes I got!! Chris did such a thorough job from beginning to end - very knowledgeable and comforting while being a great guide for the younger man working with him, Trent, who also did an amazing job. It’s super nice that they make the effort to clean up after themselves and aim to have everything look better than when they started. Very much appreciated. We’ve been a cool kids house from the start :)”

“First call for an estimate with Darren to installation by Misael was 4 days! Very impressed with the communication of Cool Kids, the efficiency, and the cost. Would recommend to anyone doing an HVAC replacement. Thank you for a very good job well done!”

“Air conditioner wasn’t cooling very well and JJ was able to diagnose the problem within 30 minutes. He was able to locate a replacement part that I needed and had me up and running the same day. I was very impressed by his knowledge and honesty. I now have service company I can depend on. I have now used their plumbing service a couple of time and I give them 6 stars. Chris Salazar has been amazing.”

“We've been using Cool Kids for a while now to help keep our dinosaur A/C unit working with minor repairs and maintenance. Recently, my husband and I knew it was time to replace the original system that came with our 23 year-old home. JJ and his team did a solid job replacing our system and we couldn't be happier. He gave us a competitive quote to replace the AC unit, furnace, and ducts. They showed up on time and were in and out in a timely manner. They hauled off our old unit and were impeccable with their cleanup. We instantly felt a major difference in the flow and quality of air. Our home cools down and warms up quickly. What a difference! Also, we had a huge dust issue which is now resolved, and we couldn’t be happier with the results. Friendly, professional, and highly recommend!”

“Kool Kids AC is hands down one of the best HVAC companies you could ever work with. They’re honest with their diagnosis, fair with their pricing, and their techs are skilled, hardworking, and quick to help—whether it’s the blazing Texas summer or those rare freezing winter days. We truly love supporting local businesses, and Kool Kids AC is definitely one we’re happy to recommend!”
