Do you service emergencies after-hours?

Yes, we offer emergency services 24-hours a day, year-round.

How much will my service cost?

The size and complexity of your HVAC issue will determine the cost. Because our trained, licensed HVAC technicians must diagnose the issue before we are able to quote you an accurate cost, we require an appointment to be set to complete a diagnostic on your system. Once the diagnostic is complete, your One Hour® technician will walk you through all costs using our Straightforward Pricing® Guide so there are never any surprise fees.

Bailey Nafziger was extremely helpful and pleasant to work with. He was able to quickly and efficiently dismantle and install the new system. Very knowledgeable and easy to work with. He explained everything about the new system as well as teaching me a few things about other components I had such as my air exchanger and dehumidifier and how to properly maintain and clean these which I knew nothing about. He definitely made this stressful situation much easier and did so in a quick manner. Highly recommended.

Brian was awesome! He taught me a lot about home electrical. He shared only a fraction of his 50 years of trade experience, and I'm forever more informed and educated because of him. Excellent service and incredibly informative. I highly recommend miser sparky to anyone, especially Brian. I only wish he did call-outs to Washington state, otherwise he'd be my go to electrician had I lived in MN.

I had a new boiler installed today with a side arm water heater and outdoor temperature. Reset it wasn’t an easy job, but Matt Cole and Tucker came to my home today and worked very hard all day and did an absolutely wonderful job. My new Boiler looks and operates beautifully. Thank you all very much for your hard work.

Jim and Ashton did an outstanding job installing our new AC and furnace! From the moment they arrived, their professionalism and expertise were evident. They took the time to explain the entire installation process, answered all our questions, and made sure we understood how everything worked before they left. The installation itself was seamless and efficient. Jim and Ashton paid close attention to detail, ensuring everything was set up perfectly and that our home was left spotless afterward. They were courteous, respectful, and truly went above and beyond to make sure we were comfortable with the new system. We couldn’t be happier with the quality of their work and the level of service provided. If you’re looking for trustworthy, skilled professionals for your HVAC needs, look no further than Jim and Ashton. Highly recommended!

We have been using One Hour and their predecessor companies for over 25 years and have always been very happy with scheduling, the service technicians and their technical knowledge and overall service experience. Recently I spoke with Kathy to set up several service appointments and Abe performed a HVAC yearly tune up. He was extremely knowledgeable and provided in depth explanations on our current system as well as suggested improvements.
