The HVAC at our rental property went out this week and our renters have a week old new born baby at the house. Our unit was almost 20 years old 😅 I called One Hour and within 24 hours, they had a new unit installed for us. ⭐️ ⭐️ ⭐️ ⭐️ ⭐️

5 ⭐⭐⭐⭐⭐One Hour lived up to their name with call back, same day service call and installation of replacement blower motor the next day. From Wendy's response, and Trent's assessment of the problem, Dustin was able to complete the repair without any complications. They used phone and text to make things simple for all.

One Hour Heating and Air did a great job on my residential HVAC service. Dustin was super thorough on diagnosing my problem and made the right adjustment. I joined the maintenance program because it’s a good value and makes good sense

Of course my heat would go out on one of the coldest days! And on a weekend! But Roman was here within an hour, had it diagnosed and up in running quickly. Roman was very knowledgeable and explained everything fully. Although I will need additional repair in the coming days, Roman was sensitive to my need for heat and now we are toasty.

I've used one hour before, I have the maintenance plan with them. Roman came out today and was very professional and efficient. He got my furnace working again. Couldn't ask for a better guy or a better company.
