Furnace Repair in Smyrna

Gas & Electric Furnace Repair Backed by Experience Since 1981

If your furnace won’t start, blows cool air, cycles repeatedly, or makes unusual noises, the cause needs to be identified before you decide what to do next. Ronald Smith Heating & Air repairs gas and electric furnaces for homeowners and small commercial property owners in Smyrna.

Because different problems can produce similar symptoms, we assess the system before recommending a repair. Diagnostic work may cover the thermostat, air filter, airflow, ignition system, burners, blower motor, heat exchanger, and safety controls.

Call (770) 766-9212 to schedule service for a furnace that isn’t heating your home or small commercial space properly.

Carrier-Recognized Service from NATE-Certified Technicians

We’re a family-owned and operated company, a Carrier Factory Authorized Dealer, and a recipient of the Carrier President’s Award. Our team includes NATE-certified technicians who service both older heating equipment and newer systems.

We identify the condition behind the symptom, explain what we find, and discuss the available options. That means evaluating whether a repair is practical rather than treating every heating problem as a reason to replace the furnace.

Signs Your Furnace Needs Professional Repair

Call for service when the furnace won’t start, produces cool air, runs in short cycles, or leaves some rooms noticeably colder than others. Burners that won’t remain lit and repeated thermostat adjustments can also indicate a problem that requires diagnosis.

Warning signs to note include:

• No Heat: The furnace doesn’t start or runs without producing warm air.
• Weak Airflow: Little air reaches the supply vents while the system is operating.
• Unusual Sounds: Banging, rattling, squealing, or other new noises occur during operation.
• Frequent Cycling: The furnace starts and stops more often than usual.
• Persistent Odors: Burning or fuel odors continue rather than clearing quickly.

A carbon monoxide alarm, strong fuel odor, or suspected combustion problem requires immediate caution. Leave the area and contact emergency services or the appropriate fuel provider from a safe location. Don’t attempt to inspect or restart the furnace.

What Happens During a Furnace Diagnosis

We begin by asking about the symptoms, when they started, and whether the furnace starts, stops, or makes unusual sounds. We then inspect and test the relevant components to narrow down the likely cause.

Before work begins, we explain our findings and discuss the proposed repair or maintenance options. If the furnace’s age, condition, or repair history makes replacement worth considering, we can explain why and help you compare it with the proposed repair.
