Theisen Heating, Air Conditioning & Furnace Cleaning

Contacted Theisen for a check up and discovered I had a fire hazard with my original heater. They came out and replaced both that and AC professionally, on-time and within budget. Highly recommend!

Ryan and his Team at Theisen Heating have been a pleasure to work with. From diagnosing issues on short notice, providing very competitive bids for a furnace replacement, and then doing what they said they would do when they said they would do it, it's been a pleasure. But beyond that, even after money was paid and the installation completed, the Theisen Team navigated the power company maze to submit and then RE-submit the Power Company's rebate process -- which meant I will get a check for $2,000 as a rebate.

My two gas fireplaces were diagnosed with leaks by Cascade Natural Gas. I then called Theisen, gave them the information I had, and made an appointment. When the technician arrived, he was friendly but told me that they don’t normally work on gas fireplaces and recommended I call a different company. I wasted my time and 135 dollars because I wasn’t informed. So, if you have a gas fireplace that needs repairs, learn from my mistake and call a different company.

I’ve used Theisen Heating and AC for years, going back to when Sam and Dennis owned the business. Always expert and top notch service at a fair price. Ryan is also superb. We had a cat die in our office building and no one could find it. Ryan was the third local company we called, thinking the terrible odor was in the duct system. It wasn’t but Ryan went the extra mile to locate and extract the critter. It’s not their line of work but demonstrates the kind of commitment he gives his customers. Can’t say enough good things about Theisen and Ryan. Thank you.
