Furnace repair cost by part.
Typical Maryland Heights repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Maryland Heights, MO, furnace repair costs are influenced by the age of the home—median built in 1974—and the mixed-humid climate. Typical repairs include flame sensors ($75–$250), igniters ($150–$425), blower motors ($375–$1,450), control boards ($300–$750), and heat exchangers ($1,450–$3,400+), plus a $75–$200 diagnostic fee. Missouri has no statewide mechanical code, so permit requirements vary locally; check with the city of Maryland Heights. Most homes use gas furnaces, and a gas furnace with AC is a common system choice. The federal 25C tax credit offers up to $600 for qualifying high-efficiency central AC, but not for furnace repairs.
