Some Words From
Our Customers

You will not find a better HVAC service than with Guardian! I got a new Daikin back in May 2024. Since then I’ve had several different technicians come out to do the regular maintenance. Every single person was great! - Isaiah, Nathan, Jeremy, Jordan, Carrington, Cayden, and anyone else who may have come out. Guardian is the Chick-Fil-A of the HVAC world 🤣. Even the internal people are amazing. I had an issue last summer and they immediately accommodated me for it. The absolute best customer service around!!! Try them out, you won’t regret it!

- Joanna Selman

We purchased a top-of-the-line Daikin variable complete HVAC system from Guardian over the summer and had a great experience- both in cost and customer service. Technician Carrington came today for our first free maintenance check on the furnace and he showed the same excellent Guardian service! He took the time to listen carefully to the details of the issue we were having with the thermostat and the fact that furnace was not cutting off when it would reach the set point. After his normal service duties at the furnace, Carrington got service manager Gio on the phone and they worked together to change/tweak several settings in the very high-tech thermostat. Then emphasized that we should call back in a few days if this does not solve the problem. Thanks so much for the great service, guys!

- Susan Coley

My Guardian appointment was for mid March, but something opened up yesterday and we were able to have them come out today. They called and let us know ow they were on the way and what the eta was. They arrived on time and were efficient and professional. We needed some minor work and were notified of another maintenence item separately. Good checkup!

- Keith Arroyo

We had Guardian install our Daikin systems, and are also having them maintain them. We've had issues with Guardian forgetting to bring air filters twice, but the quality of the techs who have come to our home have made up for that. Aspen was just at our home this morning and he is exactly who you would want in your home servicing your HVAC systems. Very kind, approachable, and professional.

- Stephen

Our family has had nothing but a phenomenal service from Guardian Home Experts. From purchasing new AC systems to maintaining regular maintenance it has been an awesome experience. The service technicians that come out are always very patient and ready to listen and answer. Any questions I have and walk me through Programming thermostats, and using the app. If anyone is looking at using Guardian Home Experts, I will definitely recommend them.

- C. Lew

Guardian replaced our water heater. The process was very simple and smooth. The technician is very knowledgeable and offered options based on our needs. I had some follow up questions and requests later. They were very patient, and did extra to make it perfect. Highly recommend them.

- Sean Cheng

Aspen was great and very knowledgeable. He was very thoughtful as well noticing my 1 year old had just went to sleep so was quiet when doing what he had to do. As well as explaining that I should keep my 1 year old out of the house when I do my vent and dryer duct cleaning. 10/10

- edwin webber jr

Tech Carrington arrived to conduct annual inspection of furnace systems. He was very professional, and courteous. He performed a thorough inspection and found a couple of issues that required immediate attention and explained why. He corrected the issues. I can strongly recommend Guardian HVAC.
