Why Coldharbour Heating & Air Is Peachtree Corners’s Preferred AC Installation Company
We’ve been serving Peachtree Corners since our founding in 2003 as an independently owned and operated member of the Kingswell network, and we’ve learned that homes here aren’t generic. The 1970s and 1980s subdivisions that make up so much of the residential base, from the neighborhoods threading off Peachtree Parkway to the streets near the Forum, each have their own ductwork quirks and humidity profiles. Our technicians are background-checked, uniformed, and trained on nine major brands including Rheem, York, and Daikin, so the person who walks through your door can work on whatever system you’re replacing.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail trees. No “call back in the morning” when your system fails on a Saturday night in July. We give you a firm arrival window, and we stick to it. Every AC installation comes with our written 365-Day Done Right Promise: if anything we installed needs correction within a full year, we return and make it right at no charge. That’s not a verbal assurance. It’s on paper before the technician leaves.
HVAC Installation in Peachtree Corners
HVAC Installation in Peachtree Corners means more than swapping out an old condenser for a new one. Most of the homes we work on here were built during Gwinnett County’s first suburban boom, from the mid-1970s through the early 1990s, with single-zone duct systems that were barely adequate even when new. Attic ductwork in these houses, especially the split-level and colonial styles near Berkeley Lake Road, frequently runs through unconditioned space with degraded flex-duct joints. A new condenser can’t fix what the ducts lose. That’s why we start every job with a Manual J load calculation, measuring insulation levels, air leakage, and solar gain rather than guessing from square footage.
For most Peachtree Corners homeowners, a full HVAC installation runs $3,500-$7,500, depending on system size, ductwork condition, and whether zoning or a second unit is needed.
When Ductwork Needs Replacing
If your attic flex ducts are original to a 1980s build, they’re likely leaking 20-30% of conditioned air into the insulation. We replace or seal duct runs as part of the installation scope, not as a surprise add-on. The written price you receive before work starts includes all duct modifications we identify during the estimate.
Load Calculations for Older Homes
We don’t size by rule-of-thumb. A 2,400-square-foot colonial on Peachtree Parkway with original single-pane windows and minimal attic insulation needs a different system than the same footprint with upgraded windows and sealed envelope. Our load calculations account for Peachtree Corners’s specific conditions, including the extra latent load from the Chattahoochee River corridor.
Heat Pump Installation in Peachtree Corners
Heat Pump Installation in Peachtree Corners has become an increasingly common request as homeowners look for efficient year-round solutions. A heat pump moves heat rather than generating it, providing both cooling in summer and heating in winter from a single outdoor unit paired with an indoor air handler. For Peachtree Corners’s climate, modern cold-climate heat pumps perform efficiently well into the 30s, covering most of our heating season without supplemental resistance heat. We install Rheem and Daikin heat pump systems sized specifically for the humidity and temperature ranges this area sees.
Heat pump installations fall within the same $3,500-$7,500 range as conventional AC installations, with variable-speed and multi-stage systems at the higher end. Many Peachtree Corners homeowners pair a heat pump with a zoning system to address the persistent hot-cold complaints common in split-level layouts.
Humidity Control With Heat Pumps
Standard heat pumps can struggle with latent load, the moisture in the air that makes a home feel clammy even at 72 degrees. We specify systems with enhanced dehumidification modes and often recommend whole-home dehumidifiers for river-corridor homes where ambient humidity runs higher than inland Gwinnett.
Dual-Fuel Options
For homeowners who want the efficiency of a heat pump with the reliability of a gas furnace on the coldest nights, we design dual-fuel systems that automatically switch between the heat pump and a gas furnace at a set outdoor temperature. The control strategy is programmed during commissioning, not left to default factory settings.
Trusted Brands We Service in Peachtree Corners
Our technicians are trained to install and service nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Peachtree Corners customers, this means we stock common parts and can source equipment quickly without waiting on regional distribution delays. We’ve found that Rheem and York systems hold up well in the high-humidity conditions along the Chattahoochee corridor, while Daikin’s inverter-driven heat pumps offer the variable capacity that split-level zoning demands. Because we work with multiple brands, we recommend equipment based on your home’s specific needs rather than pushing whatever we have in the warehouse.
Common AC Installation Problems We See in Peachtree Corners Homes
- Sizing by square footage instead of load calculation. A 1978 split-level off Peachtree Parkway with original leaky ducts and minimal insulation will fail with a system sized for new construction. We measure everything, then specify.
- Ignoring the Chattahoochee corridor’s latent load. Systems that hit 72 degrees but leave indoor humidity above 60% breed mold and generate air-quality complaints. We design for moisture removal, not just temperature.
- Installing multi-zone systems without proper commissioning. Zoning dampers and blower motors must be balanced to actual static pressure readings. On paper the SEER2 rating looks excellent, but unbalanced systems still leave upper-level rooms fighting the thermostat.
- Like-for-like swaps on split-level homes. The original single air handler serving three half-levels was barely adequate in 1980. Replacing it with the same capacity guarantees the same hot upstairs complaints. We redesign these as two-zone or dual-system installations.

FAQs About AC Installation in Peachtree Corners
Your original system was designed with one air handler feeding three half-levels, and the upper level has the longest duct runs and greatest heat gain. A straight swap won’t fix this. We redesign these as two-zone systems or add a dedicated upstairs unit, then balance static pressure until both zones hold setpoint. Call (817) 402-2972 for a free estimate on a zoning solution.
The Chattahoochee River elevates ambient humidity in lower-lying Peachtree Corners neighborhoods, adding latent load that standard systems aren’t sized to remove. We specify equipment with enhanced dehumidification and often add whole-home dehumidifiers to bring indoor humidity into the mid-40s. Call (817) 402-2972 to discuss humidity-focused system design.
SEER2 is the updated efficiency rating that reflects real-world installation conditions, including external static pressure from ductwork. A high SEER2 number on paper means little if your ducts are leaky or your installer never checked airflow. We verify actual performance with static pressure readings and refrigerant charge verification during commissioning. Call (817) 402-2972 for equipment recommendations matched to your home’s duct system.
A failed capacitor is a $150-$650 repair, not automatically a reason for full replacement. If your system is under 12 years old, the ducts are in reasonable shape, and your home’s comfort is acceptable, repair makes sense. If you’re facing repeated failures, original 1970s-80s ductwork, and persistent hot spots, replacement with proper zoning often costs less over time than band-aid repairs. Call (817) 402-2972 and we’ll give you an honest assessment with a written price for either option.
We commission every multi-zone installation with static pressure testing, damper balancing, and thermostat calibration. The system doesn’t leave until each zone holds setpoint independently. We learned this the hard way on a 1979 split-level off Berkeley Lake Road where the original Carrier air handler had left the upper level 8 degrees warm every July. After installing a two-zone Carrier system with a dedicated upstairs heat pump and whole-home dehumidifier, we spent the afternoon on readings and calibration until both zones performed. That homeowner’s humidity now sits in the mid-40s instead of the mid-60s. We apply that same rigor to every multi-zone job in Peachtree Corners.
