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.

“Duct cleaning and sealing. Tylor Robinson was very knowledgeable and efficient when working on my hearing/AC system. Along with Mikey Lienhard, the job went smoothly and was completed within the estimated time frame. At the end, Tylor clearly explained the process again and results I will see. I was very pleased.”

“I highly recommend one hour heating and AC! They came out at my earliest convenience (could've been Sooner but due to work schedule I needed the next day). Waved my fee to dispatch since I was a first time costumer, and found the issue with my furnace blowing cold air. I recommend them as well as the monthly family subscription! Jason was an amazing technician who was friendly and professional and explained things. I recommend him to anyone!”

“James Schmidt was out on a Sunday call today for no heat. James was the most knowledgeable HVAC tech we ever had come out. He identified a few key problems to why we were not getting heat and suggested several solutions and scheduled a replacement for our exhaust fan for the system when the part arrives. (Preventative due to a loud bearing going bad.) We ended up making three upgrades to our system and will be looking for a dehumidifier for the basement to prevent further issues, much thanks to James. Its never fun to spend $$$ on your system but im confident with his guideance.. Please give this man a raise!”

“James is just a wealth of knowledge on anything HVAC. We scheduled a routine furnace maintenance. He went over and above by performing a test to show us if our Furnace and Central Air was efficient for our home. He went over all of his findings and made recommendations that would be helpful to make our Furnace work more effectively for us. We were going to make an appointment to have this work completed, but he was able to do the work right away. James is very pleasant to work with , he took the time to answer all our questions and showed us exactly how the system worked. I highly recommend him for any for your HVAC needs.”
