The The Demo


I never give shout outs to businesses, clients, or vendors on Facebook; but if you are in need of HVAC sales or service give Southeast Heating and Air a call. Steve and his team are the consummate professionals and more importantly his service after the sale is incredible. He was by far the lowest price in town on the most superior products last year, and he logged nearly 12 hours over the past three days at my house fixing issues that were non related to his sale and install just to make sure that my family and I were taken care of. Top notch to say the least.

For the first night this summer I have AC. Steve worked hard all day putting in my new unit and repairing the wiring for the old unit that was run through the house. I cannot say enough good things.
