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.

FAQ
Furnace Repair questions
Why does my Philadelphia furnace keep shutting off?+
A dirty flame sensor, blocked vent or failing pressure switch are common causes. A tech can read the error code and test each safety device.
Why does my furnace turn on then off right away?+
The most common reason is a dirty flame sensor, which can't prove the flame so the board shuts the gas off. Other causes are a weak pressure switch or a blocked vent.
Is a cracked heat exchanger dangerous?+
It can be, because it may let combustion gases mix with house air. A tech will usually shut the furnace off and red-tag it until it is repaired or replaced.
