Coldharbour Heating & Air is an HVAC company serving Redan, GA, where the work is shaped by one thing: aging all-electric heat pumps in mid-century brick ranch homes fighting Georgia humidity. Most houses here went up in the 1970s and 1980s, and many still run their original systems. When a July heat wave hits Redan, those heat pumps fail hard and fast. We answer the phone with a live person 24/7 at (478) 223-8776, and we give every homeowner a written price before any work begins.
Why Redan Homes Are Different
Redan’s housing stock is dominated by single-family brick ranch and split-level homes built in the 1970s and 1980s. That means slab foundations, brick veneer, and ductwork that often runs through unconditioned attics or crawlspaces. In a humid subtropical climate, that ductwork absorbs moisture, loses efficiency, and can develop mold issues that a standard tune-up won’t catch unless the technician knows to look. The technician who shows up in Redan has to understand how these older homes actually move air.
The climate is the other half of the equation. Air conditioning runs almost year-round here. Summer highs push into the 90s, and the humidity means an undersized or aging heat pump can’t hold temperature even when it’s technically running. Afternoon thunderstorms are common, and power surges from those storms are the leading cause of blown capacitors and fried control boards on Redan streets. A technician who doesn’t know this pattern will misdiagnose the problem and replace the wrong part.
The soil matters too. Redan sits on acidic Georgia red clay, and we regularly see heat pump condensers with rusted fins and corroded coils at ground level. That corrosion isn’t cosmetic. It raises head pressure, makes the compressor work harder, and shortens the life of the system. Homeowners who get a yearly inspection catch it early. Homeowners who wait until the system quits in August usually need a much bigger repair.
Styles & brands we work with
Our Main Redan Services
The two calls Redan homeowners make most often are for AC repair and furnace repair, but a growing number are calling about full AC installation when the old heat pump finally gives out. Each service has its own Redan page with pricing, what to expect, and the written guarantee.
AC Repair in Redan
Redan’s AC repair calls spike after storm season, and the most common culprit is a blown capacitor from a power surge. We also see frozen evaporator coils from low refrigerant, clogged drain lines feeding into slab foundations, and contactors that have welded shut after years of cycling. Because so many Redan homes run all-electric heat pumps, the same outdoor unit handles both cooling and heating, which means a neglected AC problem in August becomes a heating problem in January. Every repair is covered by our 365-Day Done Right Promise: if it fails within a year, we come back and fix it at no charge. See AC Repair in Redan for full pricing and what the repair includes.
Furnace Repair in Redan
Furnace repair in Redan is less about furnaces and more about heat pumps running in heating mode. Georgia winters are mild, but a heat pump that can’t switch to heat or a dead auxiliary heat strip leaves a home cold and damp. We see failed reversing valves, bad defrost control boards, and heat strips that burned out because a clogged filter choked airflow. The same homes with original 1980s ductwork lose heat into the attic before it ever reaches the bedrooms. Every repair gets a written guarantee valid for 365 days. See Furnace Repair in Redan for what we service and what it costs.
AC Installation in Redan
When a Redan heat pump reaches 15 or 18 years old, repair after repair stops making sense. The homes here need systems sized for Georgia humidity, not just square footage, and the ductwork often needs attention at the same time. We install high-efficiency heat pumps and split AC systems matched to the house, and we give a written fixed price before any equipment is ordered. No same-day install promises; this work is load-calculated and scheduled. See AC Installation in Redan for system options and what a new install runs.

Prices in Redan run higher on homes with original 1980s ductwork because a simple swap often uncovers air leaks that need sealing before the new system will work right. Older brick ranch homes also tend to need electrical panel upgrades when moving to a higher-efficiency unit. Whatever the job, you get a written price before the first tool comes out, and that price doesn’t change at the door.

FAQs About HVAC Company in Redan
Same-day service is typical for Redan during peak cooling season. Scheduling is coordinated from our Atlanta office, but crews are dispatched locally. If you call us at (478) 223-8776 before noon in July, we’ll usually have a technician there that afternoon.
Most full-system replacements in DeKalb County require a mechanical permit, and the contractor pulls it. We handle the permit paperwork on AC installations. Repairs and maintenance don’t need a permit. We’ll tell you upfront if your job requires one.
The number one call after a strong summer thunderstorm is a blown capacitor from a power surge. Older heat pumps with original electrical components are especially exposed. A capacitor swap is one of the least expensive repairs we do in Redan, and it usually gets cooling back within an hour.
