What Our Customers Say About Us

Straight from Central Texas homeowners who’ve seen the High Caliber difference — honest work, clear communication, and comfort that lasts.

My 30+ year old AC went out and I was looking for a new unit. Spoke to 5 different AC contractors, and Chris gave me a great quote. He was able to remove and install the new AC unit the next day. He made sure the new unit was working properly before leaving. He also registered the AC unit for the 10 year warranty. I highly recommend Chris if you need an AC job. Thank you

I recently had air conditioning installed in my 800 sq. ft. garage by Chris Wilcox, owner of High Caliber Heating and Air Conditioning. From start to finish, Chris was incredibly professional and thorough. I wanted a larger unit with two heads for adequate coverage, and he took the time to discuss all of my options in detail. Even though I chose the more difficult and expensive installation route, Chris remained patient and understanding throughout the entire process.

It’s hard to find tradespeople who truly care about the quality of their work, but that is not the case with Chris. He provided a quick basic quote, came out promptly to assess the area, ordered the equipment immediately, and was ready to install soon after. The entire experience was seamless, and the results exceeded my expectations. I am beyond happy with my new AC system and deeply appreciate his professionalism, responsiveness, and attention to detail. Highly recommend!

Kimberly Kennedy

I highly recommend this company! Chris came out on Saturday (quickly) and was able to diagnose a mistake made by another company and found an additional issue that we had. He took the time to explain the issues, the way to repair them, and his prices were fair. His customer service was excellent! You can tell that he really cares about the work that he does and that is very important to me. Finding a business these days that cares about quality work/quality service is so difficult but Chris made everything easy. I will be using him for all of my HVAC needs!

Malynda McNeil

I called for a second opinion and High Caliber saved me over $5000. They were transparent about scheduling and price, honest about diagnosis and professional opinion, and answered all of my questions which gave me a better understanding of my units needs and confidence in the repairs needed to be performed. I will choose High Caliber for all of my future HVAC needs!

Tony Todaro

High Caliber provided excellent service on my service call. Chris was extremely knowledgeable and was able to diagnose and repair my AC quickly and efficiently. Definitely recommend High Caliber and will use them exclusively in the future.

Jason Greenthaner

Had a company nearby come out and told me that because the systems were 2 different brands, they would not work together. They said there was a leak but they couldn’t find it and quoted $18,000 to replace both. Chris came out and within 30 minutes found and patched the leak!!! He literally saved me 18,000 dollars. I will not go anywhere else for future needs and I will always recommend him! Plus he’s honest and straightforward about the issue which is hard to find!

Haley Ellis

Thank you to Chris for getting out to our house so quickly and being great to work with!! He was on top of it and got the parts very quickly for us as well so now we are relaxing in the cool air bliss!
