AfterHVAC Company in Roswell, GA
Dalton Heating & Air handles HVAC work across Roswell, GA with written pricing before any job starts and a full-year written guarantee on every repair. Roswell’s housing stock runs from 1970s ranch homes near the Chattahoochee to newer construction east of Highway 400, and the climate asks a lot from both cooling and heating equipment. That mix of older ductwork, humid summers, and winter nights that dip below freezing means most calls we run in Roswell involve either a worn-out capacitor or a heat exchanger showing its age. Call (361) 306-9515 and a live person answers, 24/7.
Why Roswell Homes Are Different
Roswell sits north of the Chattahoochee River at a slightly higher elevation than downtown Atlanta, which knocks a degree or two off summer highs but doesn’t touch the humidity. Homes here run their AC from May through September without a break, and the overnight lows in January routinely sit in the low 30s. That’s a long runtime for both systems, and it shows in the calls we get. Compressors in Roswell fail most often in late July after running hard for weeks, not in the first heat of June. Furnaces tend to fail on the first genuinely cold night of November, when the blower motor that’s been idle since spring finally gives out.
Housing age matters here more than in most Atlanta suburbs. The Historic District near Canton Street includes homes built before central air was standard, and many have since been retrofitted with ductwork squeezed into crawlspaces and attics. Homes in Martins Landing and Horseshoe Bend are newer but sit close to the river, where humidity cycles put extra strain on evaporator coils. East of GA-400, neighborhoods like East Cobb and Brookfield are dense with mid-2000s construction, and those systems are now hitting the 15-to-20-year mark where replacement decisions come due. The terrain matters too: Roswell is hillier than people expect, and that affects drainage around outdoor condenser units as much as it affects attic temperatures.
Permits in Roswell follow Fulton County rules for most mechanical work, and HOAs in neighborhoods like Crabapple and Edenwilde often require licensed contractors to file paperwork before outdoor equipment gets swapped. We handle that filing. It’s part of the job, not an add-on.
Our Main Roswell Services
Most Roswell homeowners call us about two things most often: an AC that won’t cool in summer and a furnace that won’t fire in winter. Heat pump installation is the third call, usually when a system from the 2000s dies and the homeowner wants to stop paying for gas.
AC Repair in Roswell
Roswell’s humid summers push air conditioners harder than anywhere north of the fall line, and the most common failures we see are refrigerant leaks at the evaporator coil, failed capacitors, and contactors that have arced themselves apart. Older Ruskin-era homes with original ductwork often show airflow problems that get misdiagnosed as a bad compressor. We trace it properly: static pressure first, then the electrical, then the charge. Most AC repairs in Roswell run $150 – $650 depending on the part and the refrigerant involved, and the repair is guaranteed in writing for a full year. Full detail is on the AC Repair in Roswell page.
Heat Pump Installation in Roswell
Heat pumps make real sense for Roswell homes because our winter lows rarely stay below freezing for long, and a cold-climate unit covers nearly the entire heating season without touching the heat strips. The catch is sizing: Roswell’s humidity means an oversized heat pump short-cycles and leaves the house clammy in shoulder season. We do a Manual J load calculation on every installation, and we quote the full job in writing before any equipment gets ordered. Installations in Roswell typically run $3,500 – $7,500 depending on capacity and ductwork condition. The Heat Pump Installation in Roswell page walks through what gets replaced and what gets reused.
Furnace Repair in Roswell
Roswell’s older homes, especially those built before 1990, still run on 80% efficiency gas furnaces with aging heat exchangers and single-speed blowers. The failures we see most are flame sensors gone lazy, pressure switches tripping on blocked venting, and inducer motors that have worn their bearings out. A cracked heat exchanger is a safety shut-off, not a patch job, and we’ll show you the crack before we tell you the repair isn’t worth it. Furnace repairs in Roswell generally run $150 – $700 depending on the part. Details, including what gets checked during the diagnostic, are on the Furnace Repair in Roswell page.
