After using them for my AC needs I will not use anyone else. They are the best by far! Kind, go above and beyond and always on time.

Excellent service. Professional and explained everything clearly to me. Showed up early and finished job earlier than planned. Highly recommend this company. 5 stars!

GNH installed our new HVAC system, and we couldn’t be more pleased with the results. Gragg was exceptionally knowledgeable and took the time to correct existing ductwork issues to ensure our new system operates as efficiently as possible. If you need HVAC work, these guys should be your first call.

GNH is Highly recommended, all options were detailed and quoted in writing with great pricing on all quotes. Gragg professionally explained all work to be performed and answered all questions until I was satisfied with the answers. Absolutely no pressure to push me into my decision or more costly up-sales. I decided to go with a new system due to the age of my old unit. I could not be happier with my new HVAC System! All work was finished on schedule! Thanks Gragg and Justin for the great install!

Had a motor freeze up and the ac couldn’t keep up during 100* heat. Called in the evening, came out next morning, quick assessed the issue, explained what happened and what needed done. Had the AC up and running promptly. Also had a blower motor go out a couple years ago and got the same responsive, detailed and quick work.
