Air conditioning in Hillsborough homes
Many houses in the historic district around Churton Street were built with no room for ductwork. Owners there often cool with ductless mini-splits, which run refrigerant lines through a small hole in the wall to heads mounted inside each room. Mini-split repairs call for a technician who works on that brand, so have the brand name ready when you call.
The newer neighborhoods off US 70 and NC 86 mostly have central heat pumps. Those systems fail the same way they do in Chapel Hill, with capacitors and refrigerant leaks at the top of the list once a system passes 10 years.
Historic district rules
If a repair turns into a replacement and the new outdoor unit needs a different spot or size, ask the technician whether the Hillsborough Historic District Commission has to approve the change. That question belongs at the quote stage, before the old unit comes out.

Why is my mini-split head dripping water?
The drain line from the indoor head is usually clogged or kinked, or the head has tilted out of level. A technician can clear the line and check the pitch in one visit.
