Reviews consistently mention quick response times, clear communication from both office and technician, and neat, well-organized installations. Many customers say the team explains options and pricing before work begins and offers practical advice on repair versus replacement. Repeat clients highlight reliability over many seasons of maintenance. Several recent reviews reference efficient system upgrades and attention to thermostat and wiring details.

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.

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!

Cannot recommend this small local business enough. Was referred to them by a friend and have been pleased since. Brent and Laura are the easiest people to work with. Brent is very fair and honest in his assessment of what needs to be done on units. Laura responds quickly to calls and messages and always keeps an open line of communication.

Brent kept an a/c unit alive for years until it wasn't feasible anymore and replaced the new one in a few hours.

Brent has been our routine maintenance / tune up person for our HVAC for over a decade.

Every year I would ask "Is it time to replace our system?". Every year he would say we aren't done yet. Our original system was installed in 2002.

Well, this was the year. Woke up one morning to find the outside unit had stopped and the lines were covered in ice. Brent came over as soon as he had time to diagnose and to get us a temporary solution.

He got us estimates on 4 options right away and even called us after hours to answer our questions.

Once installation day came, he got it installed and configured. Check out the photos of before and after. It is almost a work of art! The thermostat wasn't working quite right so he took extra time to get that working properly.

The next day we had a power blip and the thermostat essentially was "bricked ". I sent a text message and he was over the next morning (a Sunday I might add to get us going again.

He is getting a newer thermostat and will get that installed as soon as he can.

Brent has always been responsive and has a deep knowledge of all things HVAC and patiently answers all my stupid questions.

Highly recommend Gatza Heating and Air Conditioning.
