Furnace repair cost by part.
Typical Farmington Hills repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Farmington Hills homeowners pay between $85 and $225 for a furnace diagnostic, plus labor and parts for repairs. With a median home age of 47 years and cold Michigan winters, common repairs include flame sensors ($90–$275), igniters ($175–$500), and blower motors ($450–$1,650). Michigan requires a mechanical permit for furnace work, and the state's sub-zero design temperatures mean equipment must be sized for severe heating loads. Dual-fuel systems are a strong fit here, combining a gas furnace with a heat pump for efficiency in cold weather.
