Furnace Repair in Detroit: what's different
Detroit furnaces work hard through long, snowy winters. Many homes have older gas furnaces in basements that have been replaced several times without venting updates, so repairs often include checking chimney liners and draft.
Common repairs include igniters, flame sensors, inducer motors and control boards. Annual carbon monoxide checks are especially important with older equipment.
Ask the tech to check the chimney liner if your water heater still vents into the old masonry chimney. When older furnaces are replaced with high-efficiency models, the water heater may need a new liner to vent safely. Also make sure the outdoor intake and exhaust are kept clear of snow.
