AfterHVAC Company in Marietta, GA
Marietta’s mix of 1960s brick ranches, 1980s subdivisions, and newer infill construction means no two HVAC jobs look the same. Add north Georgia’s humid summers and the occasional hard freeze, and you get systems that work year-round and fail at the worst times. Dalton Heating & Air handles AC repair, heat pump installation, and furnace repair for homeowners across Marietta. If your system is down, call (361) 306-9515 and a live person answers, day or night.
Why Marietta Homes Are Different
Marietta’s housing stock spans seven decades. Homes near the Square often have original ductwork sized for older, less efficient equipment, while neighborhoods like East Cobb and Indian Hills run everything from 1990s heat pumps to modern variable-speed systems. What that means in practice: a straight swap rarely works here. Duct transitions, electrical service, and condenser pad placement all vary by era and by lot.
Humidity is the other factor. Summer dew points in Cobb County routinely sit in the low 70s, so an oversized air conditioner cools the air without removing enough moisture. Homes end up clammy at 72 degrees, and that drives calls. We size and commission every install to Marietta’s actual humidity load, not just square footage. Terrain matters too: properties up toward Kennesaw Mountain and along the ridge lines see more wind exposure, which shortens the life of poorly anchored condenser units.
Our Main Marietta Services
Most Marietta homeowners call us for one of three jobs: a system that stopped cooling, a system that stopped heating, or a planned replacement before the season turns. Each has its own dedicated page with local pricing and detail.
AC Repair in Marietta
When a central air system quits in July, you need a diagnosis that holds up. Our Marietta AC repair calls start with a written price before any work begins, and every repair is guaranteed in writing for a full year. We work on all nine major residential brands, including Rheem and Carrier, and our trucks carry the common capacitors, contactors, and condensate parts so most repairs finish in one visit. Full detail, including costs and what to check before you call, is on the AC Repair in Marietta page.
Heat Pump Installation in Marietta
Heat pumps make sense in Marietta’s climate, since they handle both cooling and heating in one cabinet. The catch is sizing: undersize it and you run strip heat all winter; oversize it and you get humidity problems in summer. We size every install with a load calculation, not a rule of thumb, and quote a fixed price in writing before ordering equipment. Brands like York and Daikin are common choices here, and we walk through the rebate paperwork with you. Details are on the Heat Pump Installation in Marietta page.
Furnace Repair in Marietta
When temperatures dip into the 20s, a dead furnace is more than uncomfortable; it can freeze pipes in crawlspaces and along uninsulated exterior walls. Our furnace repair service in Marietta covers gas and electric units, from failed ignitors to blower motors. Every job includes a written price before work starts and a one-year written guarantee. If the repair fails in that year, we come back at no charge. See typical costs on the Furnace Repair in Marietta page.

The biggest price drivers in Marietta are system age and refrigerant type. Older R-22 systems cost more to recharge than newer R-410A units, and parts for 20-year-old equipment are sometimes special-order. Whatever the job, you get a written price before any work starts, and that price does not change at the door.

FAQs About HVAC Company in Marietta
For a complete AC or furnace failure, we dispatch as soon as a technician is free, which is usually same-day. Emergency calls get priority, and our phone line is answered by a live person 24/7. Normal tune-ups and estimates are scheduled for a set window, and we arrive inside it.
Most full system replacements in Marietta require a mechanical permit through Cobb County. We pull the permit for you and schedule the required inspection as part of the job. Repairs and tune-ups generally do not require a permit.
Many Marietta neighborhoods, especially in East Cobb, have rules about condenser placement, noise levels, and visible equipment. We work with your HOA’s specific requirements before installation day, and we note any constraints on the written quote. Call (361) 306-9515 for an exact quote, estimates are free.
