H & H Heating and Air recently installed a complete HVAC system for me and I couldn’t be happier with it! Don and Donnie did a great job installing everything and explaining certain, key aspects of each unit. They were very knowledgeable, honest and didn’t try to up-sell me on anything. They’re good people and good people are sometimes hard to find these days. Hire them with confidence and you won’t be disappointed.

Don has been taking care of my A/C and heating needs for nearly 12 years. After bad experiences with another company, he came in and has done such a great job, that I'm still using my original unit and it is going strong! Call Don and son they will take care of your unit because they are professional and they care about their customers!
