Some Words From
Our Customers

Business and employees are great! Quick to answer call close to closing and were at our house first thing the next day to take care of our leaking hot water tank. Great communication and explanation of what our options were. Won’t hesitate to recommend and use this business again! Thank you!

- Kimi Funk

Not sure why our AC decided to go out on one of the hottest days of the year (117!), but Guardian responded as quickly as they could and did a fantastic job of explaining the problem and the solution. Technician Matthew Smith should be an engineer! He pinpointed the source, and had all of the proper equipment and parts. There was one more problem that he honestly discussed with me. He said the capacitor was not working as it should have been. Matt told me to run a trickle of water on it overnight to cool the capacitor down. He could have easily told me that it was broken and charged me in excess of $1500, but he offered this solution that corrected the problem the following morning. Honesty and integrity is what I admire about Guardian. You’re on our “A List!” I would highly recommend them.

- Hank Heusinkveld

My wife and I were very pleased with the timely service on our air conditioner, gas furnace, and remove and replace the water heater. Matt Smith did the reinstall of the air conditioning unit and also serviced the gas furnace. He did a great job even working overtime to make sure everything was working correctly. He explained everything to us and his personality was very personable. The men that removed and replaced the hot water heater also were very personable and answered all questions about the operation of the new heater. They did a great job on it. I appreciate Bill arranging to fix our problems in a timely fashion. There is no question that we will always be using Guardian for our cooling and heating needs. Thanks Bill and Crew Bruce and Pam Howard

- Bruce Howard

Matt Smith was wonderful! Very professional and quick to get the job done. He made sure to leave a number in case we had questions and gave advise on how to prevent the problem in future. We can’t thank Guardian Heading and Air Conditioning enough!

- Charlene DeSalme

Matt Smith and the Guardian team are the best and I while heartily think they are wonderful. They exceeded all expectations and were polite and kind. They actually care about the customer and not just money like other big companies out there. A very big thank you!!!

- Fran Warwick

At 5:45pm on a 102º evening our condenser fan and a fuse blew out. Called Guardian, got the owner, who sent his technician, Matt Smith. Took Matt less than ten minutes to identify the problem. And he had the parts we needed then and there. 30 minutes later the AC was up and running better than ever. Matt was a real pro, and in our experience he and his team from Guardian are the best in the L/C valley, by far. No better company to call.

- J Hart

Thank you for sending Matt to fix my furnace! I felt he was going to find the solution to why it wasn't working the way it was. He replaced the part that went bad and got it up and running. Very good at what he does. with a cold spell coming, I was worried about what we would do for heat and not being able to replace the furnace financially right now. He is so calming and personable and professional all at the same time. Thank you for having Matt at Guardian,! Sincerely, Shari Hoffman

- Sharon Hoffman

Matthew is absolutely amazing! One of the hottest days of the summer, 108, and my AC went down. Matthew was here for my family, working in the heat to fix the AC unit which now works! A huge thank you to Matthew! I would recommend calling this gentleman if you are ever broken down!! Excellent service!
