HVAC Installation & Replacement in Durham, NC

Durham’s housing stock is all over the map, and that is exactly why a one-size install does not work here. Near downtown and Duke you have early-1900s urban-historic homes; Forest Hills and Hope Valley filled in through the 1920s to 40s; mid-century ranches sit between them; and the southwest side toward Research Triangle Park is mostly 1990s-and-newer growth. Each era heats and cools differently, so the first thing we do on a replacement is measure, not assume.

Repair or replace? An honest read.

If your system is still under warranty and the failure is a single part, a repair usually wins. But when a unit is past its service life, leaking refrigerant, or you are sinking money into it every season, a properly sized replacement pays for itself in comfort and lower bills. We will tell you straight which side of that line your equipment is on — even when the answer is keep it another year.

Older homes near Trinity Park and Old North Durham bring their own wrinkles. Many were built for boilers or window units and have little or no modern ductwork. A high-efficiency heat pump — ducted where the structure allows, ductless mini-split where it does not — lets us add real cooling without tearing into original plaster and trim. For the larger newer homes on the RTP side, we zone the system so the upstairs and downstairs actually hold their setpoints.

Historic Durham homes were rarely built with central air in mind. In Forest Hills, Hope Valley, and the streets around Old North Durham, we often convert a tired boiler or supplement window units with a modern heat pump — ductless where running new trunk lines would mean cutting into original plaster, ducted where the attic and crawlspace cooperate.

Retrofit constraints are real, and we plan around them: tight mechanical closets, limited return air, and electrical panels that may need attention before a new condenser goes in. We walk the house first, lay out the options, and quote what the structure actually supports — no surprises after the old unit is already out.
