Coldharbour Heating & Air is a North Druid Hills HVAC company built for the area’s specific homes. The mid-century ranch and split-level houses here, built mostly between the 1950s and 1970s, run into problems newer subdivisions rarely see: undersized 100-amp panels, original galvanized ductwork, and attic runs that bake in Georgia heat. That shapes every job we do, from a simple capacitor swap to a full AC installation. Call (478) 223-8776 to reach a live person, any hour.
Why North Druid Hills Homes Are Different
North Druid Hills sits on rolling, wooded terrain just across from Emory University and the CDC, and that geography shows up inside the walls. The ranch and split-level houses along streets like Biltmore Drive and Houston Mill Road often sit on slab foundations with supply ducts run through unconditioned attics. In July, those attics hit 130°F or more, and a poorly sealed duct system can bleed 20 – 30% of its cooling before it reaches a register. A technician who knows North Druid Hills starts there, checking for collapsed flex runs and torn duct tape before condemning a compressor.
The electrical side matters just as much. Many of these homes still run on 100-amp service, which was fine for window units in 1968 and is marginal for a modern heat pump. When we quote an AC replacement in the area, we often have to include a dedicated circuit, and that explains a portion of the local price range. Summers here are genuinely humid, with daytime highs regularly above 90°F, so the system isn’t just fighting heat, it’s fighting moisture. That’s a DeKalb County problem, not a generic Georgia one.
Styles & brands we work with
Our Main North Druid Hills Services
Most calls we take in North Druid Hills fall into two buckets: a system that quit and needs AC repair, or a heating system that has to be patched through winter, which is our furnace repair work. There’s also a third, growing category: homeowners planning a full AC replacement before the next summer.
AC Repair in North Druid Hills
When a North Druid Hills air conditioner stops cooling, the work usually traces back to one of three things: a failed capacitor, a refrigerant leak, or a condensate drain that’s clogged shut with Georgia humidity. Capacitors and contactors are quick, same-day fixes. A leak takes longer because we find it, repair it, and recharge the system, and in North Druid Hills, we also check the attic ductwork while we’re up there, since a 60-year-old flex run can mimic a compressor problem. Every repair gets a written price before work starts and a 365-day guarantee. See AC Repair in North Druid Hills for full pricing and details.
Furnace Repair in North Druid Hills
North Druid Hills winters are mild, but they dip below freezing enough that a dead furnace on a January night is an urgent call. The most common repairs we make are igniter replacements, flame sensor cleanings, and inducer motor failures, often on gas furnaces tucked into the same tight crawlspaces that make this area’s retrofit work so particular. We carry common igniters and sensors on the truck, so most furnace calls in the area are finished the same visit. The technician writes the price before touching a tool. Read more on our Furnace Repair in North Druid Hills page.
AC Installation in North Druid Hills
A new system in North Druid Hills is rarely a like-for-like swap. Because the housing stock predates modern efficiency standards, we routinely have to correct undersized return ducts, add a dedicated 240-volt circuit for a heat pump or air handler, and seal the attic runs before the new equipment goes in. That’s the honest version of what a good North Druid Hills installation looks like, and it’s why our quotes are itemized and written in advance. We size equipment to the house, not to a rule of thumb. Details on AC Installation in North Druid Hills.

What North Druid Hills Customers Say
"Honest to a fault. Two companies told me I needed a whole new unit. Coldharbour said mine had years left and just needed a cleaning and a part. Saved me thousands."
- Marcus Reilly"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
- Russ Tiedemann"AC died overnight with a newborn in the house. They bumped us up the list and had it running by noon. I about hugged the guy. Fair price even on a rush call."
