Durham HVAC Services

Air Conditioning and Heating That Makes Your Home Better

After hangin’ up my Air Force pilot wings, I started what would become Green Horizon One Hour in 2007. Our goal is to make your home better with the comfort provided by quality HVAC services. It’s probably why we’re the #1 installer of home efficiency improvements in the Raleigh – Durham – Chapel Hill area. Plus, those geothermal and super high efficiency systems are freakin’ cool. And everything you choose is covered by our Whole House Promise.

Raleigh-Durham HVAC Services with a Whole House Promise

We Don't Sell You Things You Don't Need

Our Whole House Promise means we won’t recommend things you don’t need. If anything we recommend and install doesn’t improve your home’s efficiency, we’ll replace it or give you 100% of your money back within one year. This way, you can be certain that our Raleigh-Durham HVAC repairs, installation, and maintenance are services that you can trust for years to come.
