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, Ohio typically range from a $55–$150 diagnostic fee plus parts and labor. Common repairs include flame sensors ($60–$200), igniters ($125–$350), blower motors ($300–$1,150), control boards ($225–$600), and heat exchangers ($1,150–$2,700+). Marietta's median home age of 68 years means many furnaces are older and may require more extensive repairs. The city's mixed-humid climate and reliance on gas heating make timely repairs essential. Ohio requires mechanical permits and post-install inspections, though permitting is handled locally, so check with Washington County or Marietta's building department. For major repairs, a high-efficiency gas furnace with a compatible AC system is recommended.
