AfterHVAC Company in Snellville, GA
Most HVAC calls we get from Snellville aren’t simple part swaps. They’re from two-story subdivision homes built during Gwinnett County’s explosive growth between the late 1980s and early 2000s, now running original single-zone systems that can’t keep upstairs bedrooms within 10 degrees of the thermostat setting. Coldharbour Heating & Air dispatches technicians trained on nine major brands, including Trane, Lennox, and Rheem, with the written 365-Day Done Right Promise on every repair. If your system’s struggling through another humid Georgia summer, call us at (817) 402-2972. A live person answers the phone, day or night.
Why Snellville Homes Are Different
Snellville’s residential landscape was built almost entirely during one of the fastest county population booms in U.S. history. The result is a dense concentration of 2,000-3,500 square foot two-story homes, most constructed between 1985 and 2005, with ductwork run through unconditioned attics and builder-grade single-zone systems installed at construction. That equipment is now 20-35 years old and failing in clusters.
The local climate makes this worse. Snellville sits in Georgia’s humid Piedmont, where summer dew points routinely top 70°F and attic spaces regularly hit 130°F or higher. That heat load accelerates duct seal deterioration and pushes aging compressors past their capacity. Mild winters create demand for properly sized heat pump or dual-fuel systems, but original installs were frequently undersized for backup heat.
We see the same call repeatedly: a single-zone system with the thermostat downstairs while the upstairs master runs 7-10°F hotter in July. Correctly sizing and zoning replacements for these oversized two-story floor plans, rather than simply swapping units, is the defining HVAC challenge in Snellville. Many of these systems also ran on R-22 refrigerant, now obsolete, making full replacement the only legal path forward when the compressor fails.
Our Main Snellville Services
Snellville homeowners call us most often for three jobs, each with its own dedicated page and local pricing.
AC Repair in Snellville
Summer calls from Snellville usually involve capacitors cooked by attic heat, refrigerant leaks in R-22 systems we can no longer legally recharge, or compressors laboring against failed duct seals. We stock capacitors, contactors, and refrigerant-compatible components for Trane, Lennox, Goodman, and Rheem systems common to local subdivisions. Every repair comes with a written price before work starts and the 365-Day Done Right Promise. For details on same-day response and what we check first, see AC Repair in Snellville.
Furnace Repair in Snellville
Snellville’s mild winters still demand reliable heat, especially when original heat strips or gas valves fail on the first cold snap. We handle igniter replacements, flame sensor cleaning, heat exchanger inspections, and blower motor repairs on systems often squeezed into tight upstairs closets or attic platforms. Our technicians carry parts for Goodman and Rheem furnaces frequently found in local 1990s builds. Learn more about our furnace repair process and guarantee at Furnace Repair in Snellville.
AC Installation in Snellville
Replacing a system in Snellville means more than swapping boxes. We perform load calculations for two-story homes with sun-baked attic ductwork, evaluate whether zoning or ductwork re-insulation will solve the upstairs-hot-bedroom problem, and size equipment for latent humidity control, not just temperature. Installations are scheduled, not same-day, with a written fixed price and rebate paperwork handled. Read about our installation process at AC Installation in Snellville.

FAQs About HVAC Company in Snellville
We aim for same-day response on AC and furnace emergencies in Snellville, with live phone coverage 24 hours a day. Dispatch is coordinated from our Atlanta office, and most Snellville calls reach a technician within a few hours during business hours, longer overnight depending on call volume. Call (817) 402-2972 to check current availability.
Many Snellville subdivisions built during the 1990s and 2000s have active HOAs with exterior equipment placement rules. We photograph the existing pad and line set path, note any fence or screening requirements, and provide documentation you can submit to your HOA board before we schedule the install. We do not start work until you confirm approval.
We can repair R-22 systems using reclaimed or stockpiled refrigerant where possible, but EPA regulations prohibit new R-22 production. When the compressor fails or the leak is extensive, replacement with modern R-410A or R-32 equipment is the only legal and practical path. We explain this during diagnosis and provide a written price for both repair and replacement options.

What Snellville Customers Say
"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."
- Celeste Ngo"The repair was done well and quickly. Scheduling over the phone was a little clunky and I got transferred twice, but the tech himself was great and on time."
- Brett Haygood"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
