Philadelphia
Furnace Repair in Philadelphia: what's different
Many Philadelphia homes have gas furnaces or boilers in the basement, often decades old. Furnace repairs commonly involve igniters, flame sensors, inducer motors and venting issues, particularly where older chimneys are still in use.
Because many basements are damp, rust on furnace cabinets and burners is common. PGW customers can call the utility's emergency line if they smell gas before arranging repairs.
If your basement is damp, ask the tech to check for rust on the burners and heat exchanger. Moisture can shorten furnace life and cause ignition problems. Ask whether a dehumidifier would help protect the equipment, and have the venting and chimney liner checked during the visit.
