I can't say enough good things about Guardian. Duane (the owner) is friendly, professional, trustworthy, and just super good at his job. I would not hesitate to recommend Guardian for your HVAC needs. I know that this is the company I will be calling for future maintenance of my system and for replacement when that time comes. Don't hesitate -- call Guardian if you need HVAC service .

Guardian is such a great company. They responded within an hour after I left a message. They came out same day and fixed my problem. Duane is very knowledgeable and kind. I highly recommend this company and will definitely use them again if I were to run across another problem. They were recommended to me by a friend and I’m so glad.

They came out on a Sunday to get my air conditioning back up and running. Then when I needed a new system (mine was 22 years old) they beat the other bid by a lot with a better system. Great company to do business with, these guys are great.

Duane and Aaron did a tremendous job installing our new AC unit. They were very fair with their pricing, didn’t try to over sell me and were extremely professional/knowledgeable. Everything looks amazing and is running much more efficiently. My family will definitely be using Duane and Aaron for any of our future HVAC needs. Thank you so much for the great work.

My heat went out in the night and it got down to 50 degrees in my home with my 4 month old, 2yr old, and 7 yr old daughters. I was desperate and called Anthony's heating and cooling. They came out and told me that the part needing fixed would be around $1,300 and then sent out a sales guy to try to sell me the bottom barrel furnace for nearly $5,000. In getting another quote, I called Duane(sp?) and gave him the details on everything and my experience. At this time, I was on Day 2 of no heat. Duane said he'd have to check on the part after I texted him some photos. He called back within 1 hour
