Lithonia takes its name from the Greek words for stone and city, and granite has shaped the area since its quarry days. Today, homes around Lithonia range from older houses near the historic downtown to large subdivisions built in the 1980s, 1990s, and 2000s, many within sight of Arabia Mountain’s rocky outcrops.
Ace & A HVAC, Heating & AC Repair offers furnace repair in Lithonia, GA from a family-owned company that has served greater Atlanta since 1975. We treat every customer with honesty and respect.
Not every furnace problem is obvious. You might need a repair if you notice any of the following.
A sulfur or rotten egg smell can mean a gas leak, so leave the house and call your gas company first.
Granite sits close to the surface across much of the Lithonia area, and thin soil over solid rock doesn’t absorb water well. Heavy winter rains run off quickly and can collect around foundations, raising humidity in the basements and crawlspaces where furnaces are installed. Over time that moisture corrodes burners, heat exchangers, and electrical connections.
Newer subdivision homes have their own challenges. Larger floor plans mean longer duct runs and furnaces that work hard to reach every room. We often find clogged condensate drains on high-efficiency models, worn blower motors, and failing flame sensors in systems that haven’t had regular maintenance.
Whether your furnace is a decades-old standard model or a newer high-efficiency unit, our team is ready to repair it. Technicians complete factory training every year and service all major brands, so they understand the differences between older and newer systems. We test safety controls, gas supply, ignition, airflow, and venting on every visit.
You’ll always receive a written estimate before repairs begin. Financing is available for larger jobs, and our 24/7 emergency service is there when your furnace quits at night or on a weekend.
Brenda called us one December evening because her furnace fan kept blowing even though the burners had shut off and the house was getting colder. She’d lived in her Lithonia home for about ten years and had never had a problem like it.
Our technician traced the issue to a tripped rollout switch, then found the cause behind it, a cracked heat exchanger letting flames escape the burner area. He shut off the gas, showed Brenda the crack, and explained why repairing that furnace wasn’t safe. With a written estimate in hand, she chose a replacement, and our team had her home warm again the next day.
For more than 50 years, families across greater Atlanta have trusted us with their heating. Here’s why Lithonia homeowners do too.
