Fast, Reliable AC Installation Across Loganville
AC installation in Loganville typically costs $3,500-$7,500 for a complete system replacement, and most jobs are scheduled within a few days after your free in-home estimate. We’re Coldharbour Heating & Air, and our AC Installation team has been working in Loganville’s subdivisions long enough to know the difference between a home built in 2002 and one built in 2007-and why that matters for sizing your new system correctly. Dispatch and scheduling are coordinated from our Atlanta office, but our crews live and work in the Loganville area, so we understand the local permitting quirks, the county-line confusion, and the specific cooling problems that show up in homes from the mid-2000s building boom. Call (817) 402-2972 for a free estimate with a written price before any work begins.
Why Coldharbour Heating & Air Is Loganville’s Preferred AC Installation Company
We’ve been serving Loganville since the first wave of those big two-story homes started needing real HVAC attention. Our technicians are background-checked, uniformed, and trained on nine major brands including Trane, Lennox, Goodman, and Rheem-so whichever system is in your home, we can replace it with something that actually fits. A live person answers our phone 24 hours a day, 7 days a week, and we give you a firm arrival window, not a four-hour guess.
Our 365-Day Done Right Promise means every repair comes with a written guarantee. If it fails within a full year, we come back and correct it at no charge. That guarantee is written down before the technician leaves, not offered as a verbal afterthought. We also hand you the full price in writing before a single tool comes out of the truck. That’s The Kingswell Way: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if it fails.
We recently replaced a builder-grade 3-ton heat pump in a 2004 two-story home in the Bay Creek subdivision near the Walton-Gwinnett line. The original system had a mismatched evaporator coil and ductwork sized for a model-home floor plan, causing the second floor to stay 5-7 degrees warmer than the first. After pulling the correct Walton County permit, we installed a new Trane 14.3 SEER2 heat pump, rebalanced the ductwork, and added a return in the upstairs hallway-now both floors hold within 2 degrees.
Ductless Mini Split Installation in Loganville
Ductless Mini Split Installation in Loganville is often the right fix for homeowners who’ve fought with hot second floors, converted garages, or additions that the original ductwork never reached. These systems use an outdoor compressor connected to one or more indoor wall units through a small refrigerant line-no ducts required. In Loganville’s 2000s-era subdivisions, we’ve installed dozens of these as zone solutions for homes where the builder’s original system was never designed to cool the actual living space. A typical ductless mini split installation runs $3,500-$7,500 depending on the number of indoor heads and the electrical work needed.
When Ductless Makes Sense
We recommend ductless when your existing central system is properly sized for the original footprint but can’t handle a finished basement, a bonus room over the garage, or that sun-exposed back addition. The indoor units are whisper-quiet and each has its own thermostat, so you’re not cooling empty rooms to make one space comfortable.
Electrical and Line-Hide Options
Most Loganville homes from the building boom have 200-amp panels that can handle a mini split add-on, though older or smaller services may need a subpanel. We run the refrigerant lines through walls or behind slim exterior conduit painted to match your siding-no exposed tubing snaking down the brick.
AC Replacement in Loganville
AC Replacement in Loganville is a different job than in older, slower-growing cities. Our population roughly doubled during the mid-2000s Atlanta exurban building boom, filling Walton County with large subdivision homes built between approximately 2000 and 2008. Those original heat pump and split-system installations are now 15-25 years old and hitting end-of-life simultaneously. If your system was installed when your home was built, you’re not alone in calling us this season. A full AC replacement in Loganville runs $3,500-$7,500, with the final price depending on equipment size, efficiency rating, and whether your ductwork needs modification.
The Load Calculation We Actually Do
We run a Manual J load calculation on every replacement-measuring your home’s square footage, insulation, window exposure, and duct leakage. Builder-grade systems were often sized by rule of thumb, which leads to short cycling, humidity problems, and premature compressor failure. We don’t guess.
What Happens to Your Old Equipment
We haul away the old condenser, coil, and refrigerant, and we recycle the metal through an EPA-certified handler. You won’t find a dead compressor rusting behind your fence six months later. That’s part of leaving the job site cleaner than we found it.
Trusted Brands We Service in Loganville
Our technicians are trained to service and install Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Loganville customers, we stock common parts for Trane, Lennox, Goodman, and Rheem locally, which means faster turnaround when your system needs attention during a July heat wave. We don’t push one brand over another-we match the equipment to your home’s load calculation, your efficiency goals, and your budget. Every system we install carries the manufacturer’s warranty plus our own 365-Day Done Right Promise on the installation workmanship.
Common AC Installation Problems We See in Loganville Homes
- Short cycling from oversized equipment. Builders in the 2000s frequently installed 4-ton systems where a 2.5-ton unit was correct, causing the compressor to start and stop every few minutes. That wears out contactors, strains capacitors, and never lets the system run long enough to dehumidify your air properly.
- Second floors that won’t cool. The dominant housing stock in Loganville is 1,800-3,200 sq ft two-story homes with ductwork sized for model-home floor plans rather than actual layouts. We find restricted supply runs and missing returns in upstairs hallways on almost every service call in subdivisions like Bay Creek and Grayson Park.
- Failed auxiliary heat strips discovered too late. Loganville sits in the Georgia Piedmont at roughly 950-1,050 ft elevation, and the I-20 corridor east of Atlanta sees disproportionate winter ice events. Heat pumps carry nearly all the cooling load through humid summers, but when that first hard freeze hits, homeowners learn their auxiliary heat strips failed years ago.
- Warranty registration gaps. Original builder warranties often expire before the first major repair, leaving homeowners surprised when the evaporator coil or heat exchanger fails. We check your remaining manufacturer coverage before quoting replacement, and we register new equipment in your name so you’re protected.
Pricing for AC Installation in Loganville, GA
We’re upfront about what AC installation costs because nobody likes a price that jumps at the door. Here’s what we see in the Loganville market:
| Service | Typical Price Range |
|---|---|
| AC Installation (full system replacement) | $3,500-$7,500 |
| AC Repair | $150-$650 |
| Tune-Up / Maintenance | $80-$200 |
Your final installation price depends on three things: the cooling load your home actually requires, the efficiency rating you choose (14.3 SEER2 is the current federal minimum, with 16-18 SEER2 available for better humidity control and lower bills), and whether your existing ductwork can handle the new system’s airflow. Because Loganville straddles the Walton-Gwinnett county line, AC installations in subdivisions near the border require confirming which county’s inspection authority applies-Walton County’s permitting office versus Gwinnett’s-a jurisdictional split that has tripped up out-of-area HVAC companies who assumed Gwinnett rules applied countywide. We handle the permit pull and inspection scheduling as part of every job. Call (817) 402-2972 for a free estimate with a written, fixed price.

FAQs About AC Installation in Loganville
If your system is 15-20 years old, needs refrigerant more than once a season, or your summer electric bills have climbed 30% or more, replacement usually makes better financial sense than another repair. A $400 repair on a system that’s already leaked out its R-22 refrigerant is money you’ll spend again next year. We give you an honest assessment-call (817) 402-2972 for a free evaluation and a written replacement quote if that’s the smarter path.
Your ductwork was almost certainly sized for the builder’s model-home floor plan, not your actual layout. Quick-build construction in Loganville’s 2000s subdivisions left supply runs too small and return air pathways missing upstairs. We measure static pressure and airflow room by room, then redesign the ductwork as part of your AC installation so both floors cool evenly. Call (817) 402-2972 and we’ll show you exactly what’s restricted.
Yes, all AC replacements require a permit, and because Loganville straddles the Walton-Gwinnett county line, the correct permitting office depends on your exact address. Homes in Bay Creek and subdivisions west of Highway 78 typically fall under Walton County; areas closer to Grayson may be Gwinnett. We verify jurisdiction and pull the permit for you-it’s included in our installation process, not an extra fee or something we ask you to handle. Call (817) 402-2972 and we’ll confirm which authority applies to your home.
We size every system with a Manual J load calculation-never rule of thumb. A 2,400 sq ft Loganville home with good insulation and standard windows might need 3 tons; the same footprint with west-facing glass and a vented crawl space might need 3.5 or 4. Oversizing causes short cycling and humidity problems. Undersizing means the system runs nonstop and still can’t keep up. Our estimate includes the full calculation so you know the number is right for your specific home.
Most residential replacements are completed in one day, assuming the existing electrical and ductwork are in reasonable condition. If we need to reconfigure ductwork for a second-floor return or modify the electrical panel, the job may extend to a second day. We give you a firm schedule with your written price, not a vague “sometime next week.” Call (817) 402-2972 to book your installation date.
Ready to replace that builder-grade system with something sized for your actual home? Call Coldharbour Heating & Air at (817) 402-2972 for a free, written estimate. We’ll show up in the window we promise, give you the full price before any work begins, and back every installation with our 365-Day Done Right Promise in writing.
