We worked with Aaron today, Oct. 8,2025. Aaron and the entire team are so professional and courteous. Aaron brought to our attention that our condenser is not performing to like it should and that it will be needing to be replaced. He mentioned that we could replace it today since he had the part available or we could just monitor it. There was absolutely no pressure to have it replaced right then and there just that it would need to be replaced soon, he left all up to me. Every technician I worked have been straightforward about what needs attention. I want to Thank the entire team at Aero Design Systems. You all are a great, friendly, honest team that performs with integrity which is hard to find these days! Keep up the good work. Thank you again!

He has helped friends of mine as well in the past with similar results, that is how I got his information. I can not say enough good things about him, an old school Austin gem.

We had a wild storm and a bolt of lightning found its way through our home (and myself, but that's another story). Nearly everything in the house with a circuit board was fried, including the A/C unit, furnace, zone control boards, and the physical air conditioner's contactor. Literally blown up! I called at 8am and Logan showed up three hours later. Basically, everything was busted or malfunctioning. Left was right, up was down, hot was cold. This lightning did a number on us. Seeing this mess, Logan called in for backup from Pete, the owner with decades of experience. Pete made it his mission to "hack" our system to making A/C for the night. It didn't seem too difficult for him, but you could tell he wasn't leaving until our baby daughter had A/C in her room (it's July). The next day, the men showed up with the replacement parts and a few hours later, we were back up and running 100%. They documented everything wonderfully for our insurance claim and even took a ton of time to chat and give me tips for the house we're building right now. I'll definitely have Pete come in and make sure the next house is configured properly. I'm sure there are other great HVAC services in southwest Austin and surrounding areas, but I won't need to find out. Pete's got my business no matter what. Thanks guys!!

Pete, the owner and his associate, showed up in his van (with their logo proudly displayed.) He introduced himself and spoke with my husband about our air conditioning issues.

He even asked about our return filters and eagerly replacefor us with the filters we had on hand. We signed up for their maintenance program, which is a great deal!! I highly recommend this company and their wonderful service !! Wonderful family owned company that makes you feel secure with their service !!! Thank you Pete and Nancy keep up the great work !! So I knew our heater/air conditioning system was starting to fail when the fan would not stop running ! I called Nancy and she scheduled Pete to come out ! He tried everything, thinking it may be our Nest Control, he even replaced it with a New Honeywell Control. Nope, it was the AC/ Heater Unit !! Our home was built in 1994 so, that's understandable!! He ordered a Nee Unit and his Crew was there the very Next Day ! Christian and Joseph did Great Work and covered Everything!! Nice !! I'm So Impressed with this Company !!

I would have never known if I tried to fix this myself. I am always hesitant about calling a company to come do work because even the smallest little thing would cost me a few hundred dollars at least. As John was fixing and replacing things, he would also give little informational tidbits and explain what things were and what he was doing along the way. I can't say I didn't learn anything because I did pick up a few things here and there. He was very knowledgeable and definitely knew what he was doing. In the end, I would highly recommend John for all your HVAC needs. He does everything carefully and professionally at a VERY reasonable price.

'Busy keeping Austinites cool... we'd like to help you..' leave your name and number. Our nearly 10-20 year old system had lost a battle against a 90 degree Austin day. I'd called a few HVAC contractors, all came to the conclusion that the Evaporator Coil had likely sprung a leak and was freezing up, causing the Fan to run for Hours...without managing to actually cool the house down. Two courses of action were available - spend a few hundred dollars adding 2-3 lbs of refrigerant to the system - to maybe get beyond the 2023 Summer Cooling System (fingers-crossed) or Replace the system entirely. I opted for the second. I'd never had to have an AC system installed/replaced before. After bidding out a few HVAC contractors in South Austin, I realized that most HVAC contractors have middlemen do actual change-out work... and later come-back to check their work. I didn't like that setup considering I'm investing $5-10,000 in parts/labor. No Thank You. Regan, the business owner of Cool Champs instead is involved from start to finish. Regan and crew did a meticulous job of pulling out the old equipment, hauling it off, installing the new equipment, and cleaning up their work area afterwards. Regan is passionate about the work he does. He welcomes questions about how the HVAC system works. How best to maintain your system, and how to keep your system running great. Anyone that has HVAC related needs should give Cool Champs/Regan a call. A great team to do business with!
