What We Offer
Furnace Service in a Heat Pump Region
Gas furnaces are less common in coastal North Carolina than they are further inland, since our mild winters make heat pumps the default. But plenty of Wilmington homes do run a furnace or a dual fuel system, and when you have one, you want a company that services them properly and takes the safety side seriously.
Air Support installs, repairs, and tunes furnaces of every major brand. We are veteran owned and local, we quote flat rates before any work begins, and we treat a furnace with the care a combustion appliance deserves. Same day service is available for most furnace repairs.
Safety Comes First With Combustion Heat
A furnace burns fuel to make heat, which means a cracked heat exchanger, a failing flame sensor, or a blocked flue is not just a comfort issue, it is a safety issue. Carbon monoxide is odorless, and a furnace that is not venting properly can put a family at risk. When we service a furnace, checking that it is burning and venting safely is not an upsell, it is part of the job.
If you notice a furnace short cycling, a burner that will not stay lit, or any soot or unusual smell, do not wait. Call us and we will inspect it properly before it becomes a hazard.
Repair, Tune, or Replace
Whether your furnace needs a specific repair, an annual tune up to run safely and efficiently through the winter, or has reached the end of its service life, we give you a straight assessment. When replacement is the right move, we help you weigh a new furnace against a heat pump or dual fuel system that may fit the coastal climate better.
New system installs qualify for financing through Enhancify and GreenSky, and come with a one year labor warranty.

“Air Support was incredible! They came out same day when our AC went out in the middle of July. The technician was professional, explained everything clearly, and had us back up and running in no time. Flat-rate pricing meant no surprises. Highly recommend!”

“We had a new heat pump system installed and the whole process was seamless. Free estimate, fair pricing, and the installation was completed in one day. The team was respectful of our home and cleaned up after themselves. Can't say enough good things.”

“Being a veteran myself, I love supporting veteran-owned businesses. But beyond that, the quality of work is outstanding. They installed a mini-split in our sunroom and it works perfectly. Professional from start to finish.”
