What our Customers are Saying

Very professional, Very reliable! My husband had had eye surgery when our furnace quit I had called another company but they were 4 hours late. When they were here they didn’t fix what they said. After a cold night, they came back. After a long drawn-out affair, we called DJ, and within 2 hours of trying to work us in DeGraffenreids was here within 45 mins the furnace was fixed and it runs great! If you need a reputable, reliable company we totally recommend DeGraffenreids!!

Diana Dinwiddie

I cannot say enough wonderful things about the folks at DeGraffenreid Heating and Cooling. Cherish answers the phones and is so good about calming your heating/cooling panic and handing you over to DJ to ask questions of a technical nature if needed. Sheldon is the epitome of the perfect service person; he knows his craft well, is super friendly, and very clean and courteous. Folks, there is absolutely no reason to look further than DeGraffenreid for all your HVAC needs! Thank you DeGraffenreid—you are a blessing to our community!

I own a general contracting business and have been using DeGraffenried HVAC for years. I rarely ever get an estimate on a project from anyone else because they are always priced very reasonably and always do a fantastic job. Highly recommended.
