Showed up on time, very informative. Used him through our warranty service. Fixed our furnace and ensured it fired up appropriately. Even showed us how to use our air filter attached. Easy $100 for him as our furnace leak was just a loosened joint. I was skeptic given reviews, but also didnt have a choice of who warranty picked. I am satisfied with service.

DO NOT USE THIS SERVICE!!! Been dealing with or AC unit not working for a month and still not resolution, will not answer or return calls. This man is a scam and a terrible person to work with! Beware!!! Refer to the reviews on the BBB for more information. Call anyone else besides Derwin!!!!!

Derwin Hairston is a good man and his company is reliable,dependable,and trustworthy I recommend to use to service if anything was to ever need fixing in your house. I say that because I use this service before and I love it. I will use it again
