Furnace repair cost by part.
Typical Marietta repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair costs in Marietta, Georgia typically range from $80 for a simple flame sensor replacement to over $3,500 for a heat exchanger. Most homes in Marietta were built around 1985, meaning many furnaces are nearing or past their expected lifespan. A diagnostic fee of $75–$200 is standard. Because Georgia follows the IECC-based state energy code, a mechanical permit is required for any repair that involves replacing major components. Licensed contractors must perform the work. Given Marietta's hot-humid climate and mixed heating needs, a heat pump is often recommended for both efficiency and cooling, and federal 25C tax credits (up to $2,000) may apply for qualifying high-efficiency systems.

Recommended unit for Marietta
Given Georgia’s hot-humid climate and mixed heating, high-seer2 heat pump is the sensible default for most Marietta homes. With a long, hard cooling season here, stepping up the SEER2 tier pays back through lower summer bills. A pro can confirm the right size and system for your home with a load calculation.

- Good to know—
Georgia follows the IECC-based state energy code; mechanical permits and licensed-contractor installs are required, and Manual J/S sizing is recommended practice but not strictly code-enforced on changeouts.

Furnace Repair in Marietta, explained.
What Affects Furnace Repair Costs in Marietta
The age of your furnace (often 40+ years in Marietta's older homes) can make parts harder to find, raising labor time. The specific component matters: a flame sensor ($80–$250) is far more affordable than a blower motor ($400–$1,500) or heat exchanger ($1,500–$3,500+). Permit fees and the need for a licensed contractor add to the baseline. Seasonal demand—peak winter or summer—can also influence pricing. Finally, if a Manual J load calculation is done (recommended but not required), that may add a modest cost but ensures proper sizing.
Common Furnace Repairs in Marietta
Flame Sensor Failure
A dirty or faulty flame sensor prevents the furnace from igniting. Typical repair cost: $80–$250.
Igniter Problems
A cracked or worn igniter stops the burner from lighting. Repair cost: $150–$450.
Blower Motor Malfunction
A failing blower motor reduces airflow or stops the fan. Repair cost: $400–$1,500.
What to Expect During a Furnace Repair in Marietta
A licensed technician will first run a diagnostic ($75–$200) to identify the issue. They will then provide an upfront cost estimate for parts and labor. If the repair requires a permit (e.g., replacing a heat exchanger or major component), the contractor will pull the mechanical permit from the local building department. The job typically takes 1–4 hours depending on the part. After repair, the system is tested for proper operation and safety.
