A new AC installation in Redan, GA typically runs $3,500-$7,500 for a complete central air system, and most jobs are scheduled within a few days after your free in-home estimate.

Call (817) 402-2972 today to book a free estimate with a written, fixed price before any work begins.
We’ve been working in Redan long enough to know that a straight equipment swap rarely solves the real problem. The brick ranch and split-level homes built during the 1970s-1990s suburban boom along Covington Highway and US-278 almost always have original flex duct in the crawl space that’s sagging, pulling loose at the plenum boot, or simply undersized by today’s standards. That ductwork was never designed for modern SEER2 equipment, and ignoring it is why so many “new” systems in Redan run all day without cooling the back bedrooms.
Why Coldharbour Heating & Air Is Redan’s Preferred AC Installation Company
We’ve built our reputation in Redan by treating the house as a system, not just swapping boxes. Our technicians are trained on nine major residential HVAC brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so whatever equipment you choose, the crew that shows up can install it properly. Every installation comes with our written 365-Day Done Right Promise: if anything fails within a full year, we return and correct it at no charge.
Our dispatch office coordinates scheduling for Redan specifically, which means we understand the permitting quirks of unincorporated DeKalb County. Unlike incorporated cities with their own inspectors, Redan falls under county jurisdiction where a full AC replacement can trigger a separate duct inspection. Our crews photograph crawl-space duct condition on every initial visit so there are no permit delays after equipment arrives.
Phones are answered by a live person 24 hours a day, 7 days a week. When you’re ready to replace an aging system in the Redan Road area, near Redan Park, or off South Hairston Road, you’ll speak to someone who can book your free estimate immediately.
Furnace Installation in Redan
Furnace Installation in Redan addresses a specific need in this market: many homes here rely on gas furnaces for winter heating, and units installed during the 1980s and 1990s are well past their 15-20 year service life. A proper furnace installation starts with a Manual J load calculation to match the right BTU output to your home’s actual heat loss, not the old unit’s label. In Redan, furnace installation typically falls within our $3,500-$7,500 range for complete system replacement, depending on efficiency tier and whether duct modifications are needed.
When to Replace Rather Than Repair
If your furnace is over 15 years old, needs repeated ignition or heat-exchanger repairs, or can’t maintain even temperatures across the house, replacement usually saves money within a few seasons. We see this constantly in the ranch homes near Redan Park, where original 80% AFUE furnaces are still running but costing homeowners in gas bills and repair calls.
Gas Line and Venting Checks
Older Redan homes often have original gas lines and venting that need evaluation before a modern high-efficiency furnace goes in. Our crews check these during the estimate so the written price includes everything, not just the equipment swap.
HVAC Installation in Redan
HVAC Installation in Redan means more than hanging a condenser and air handler. It means evaluating whether your 30-to-50-year-old duct system can handle modern airflow requirements, whether your electrical panel can support a new condenser’s inrush current, and whether your home’s single-zone setup is causing the temperature imbalances you’ve learned to live with. Complete HVAC installation in Redan runs $3,500-$7,500, with the final figure depending on equipment efficiency, duct condition, and any electrical upgrades needed.
Load Calculation Before Equipment Selection
We run a full Manual J load calculation on every installation. In Redan’s humid Georgia Piedmont climate, oversized equipment short-cycles and fails to dehumidify, leaving you cold and clammy. The right size matters more than the biggest unit.
Single-Zone Limitations
Most Redan homes were built with one thermostat controlling the whole house. We can discuss zoning options or duct redesigns that address the classic complaint: the front rooms freeze while the back bedrooms stay warm.
Trusted Brands We Service in Redan
We install and service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment. For Redan homeowners, this means we stock common parts and can source units quickly without long lead times. We regularly install Trane and Lennox systems for customers who want premium efficiency ratings, and Goodman and Rheem for reliable performance at a lower upfront cost. Whatever brand you prefer, you’ll get the same written price before work starts, the same firm arrival window, and the same 365-Day Done Right Promise.
Common AC Installation Problems We See in Redan Homes
- Original flex duct sagging in crawl spaces. In Redan’s 1965-1995 ranches, decades of Georgia humidity have weighed down flex duct runs until they hang below the floor joists, crushing airflow to back bedrooms and creating condensation that breeds mold.
- Like-for-like tonnage replacements. Many contractors simply match the old unit’s size, but that original equipment was often oversized to begin with. A proper load calculation frequently reveals Redan homes need smaller, longer-running systems that actually dehumidify.
- Aging electrical panels. The original panels in Redan’s suburban-era homes may not have capacity for a modern condenser’s requirements. We check this during estimation so you’re not surprised by an electrical upgrade mid-project.
- Unbalanced single-zone systems. A single thermostat in a split-level or ranch with poor return air path design leaves some rooms overcooled and others untouched. We address this with duct modifications, not just bigger equipment.
Pricing for AC Installation in Redan, GA
Most complete AC installations in Redan fall between $3,500 and $7,500, including equipment, labor, and basic materials. What moves you within that range: the SEER2 efficiency tier you choose (14.3 SEER2 minimum versus 16+ for Energy Star), whether your existing ductwork can be reused or needs replacement, and whether your electrical panel requires upgrading to meet current code.

FAQs About AC Installation in Redan
Your system is likely oversized and short-cycling, which is extremely common in Redan’s 1970s-1990s homes where original equipment was spec’d too large. An oversized unit cools the air quickly but shuts off before it runs long enough to pull moisture out. We fix this with a proper Manual J load calculation and right-sized equipment that runs longer, dehumidifies better, and actually shuts off when the house is comfortable. Call (817) 402-2972 for a free assessment.
You don’t always have to, but in Redan you probably should. The original flex duct in these crawl-space ranches is now 30-50 years old, often sagging, and frequently undersized by current Manual D standards. DeKalb County’s unincorporated permitting process can require a separate duct inspection on replacements anyway, so we photograph and evaluate your duct run on the first visit to avoid delays. Call (817) 402-2972 and we’ll show you exactly what we found.
No. Matching old tonnage is one of the most common mistakes we see in Redan, and it leads directly to humidity problems and premature equipment failure. Your home’s insulation, windows, and air leakage have changed over decades, and the original unit was often oversized to begin with. We run a fresh load calculation to size your new system correctly for the house as it exists today. Call (817) 402-2972 to schedule a proper evaluation.
SEER2 is the updated efficiency testing standard that more accurately reflects real-world conditions, including the static pressure of duct systems like those found in Redan’s older homes. A higher SEER2 rating means lower operating costs, but only if the ductwork can deliver the airflow the equipment needs. We evaluate both together so you’re not paying for efficiency you can’t actually achieve. Call (817) 402-2972 for equipment recommendations matched to your home.
Possibly. Many Redan homes still have original panels from the 1970s-1990s that lack the capacity or breaker spaces for a modern condenser. We check your panel’s condition and available amperage during the free estimate, and if an upgrade is needed, we include it in the written price so there are no surprises at installation. Call (817) 402-2972 to have us take a look.
