I've been a customer of Gatza Heating & Air Conditioning for many years. This company was built on a foundation of true professionalism and integrity. It's always a pleasure to work with Brent and Laura.
Christopher Riffel
Brent and Laura Gatza are excellent! Brent replaced and upgraded my HVAC system to a 2 stage system in 2024 (under 20k, including labor) and things have been great. He got 3 bids, walked us through the right system, and was able to do the install by himself within a week of the bid in a 2 day job and went the extra mile to make sure the electrical was run to the thermostat to hook up to my ecobee, and he made no mess, it actually looks better and sealed up the exterior better than it was previously. Not to mention the price was better than the big name companies. Humidifier filters are ignored by some companies on maintenance but Gatza is on top of this too! Great for maintenance visits twice annually, they do it all!

I had an amazing experience with Gatza Heating & AC repair! From the moment I called, their customer service stood out — friendly, professional, and genuinely eager to help. They responded incredibly quickly and had a technician at my home the same day, which was a lifesaver during this summer heat.
They were knowledgeable, efficient, and explained everything clearly. What really impressed me was how affordable the repair ended up being — no surprise fees or upselling, just honest, quality work at a fair price.
It’s rare to find a company that checks all the boxes: fast response, excellent customer service, and affordability. I’ll absolutely be using them again and recommending them to friends and family!
