Short answer
We handle furnace and water heater repair in Cobbs Creek, and our phone is answered 24 hours a day. A tech restores your heat or hot water, then tests the flue the two appliances usually share and checks for gas leaks and backdrafting, because a fault in one of them often traces back to the other.
Two gas appliances, one flue: how Cobbs Creek basements work
Cobbs Creek runs along the western edge of Philadelphia, where the creek forms part of the line with Delaware County. Its blocks are lined with brick rowhomes, many with front porches, and census figures reported by The Philadelphia Inquirer show most Philadelphia homes were built before 1950. In houses of that age the mechanical room is the basement. A gas furnace or boiler and a tank water heater usually stand a few feet apart, tied into the same chimney.
That shared flue is where a lot of trouble begins. When a furnace is replaced with a high-efficiency model that vents out the side wall, the water heater is left alone in a chimney sized for two appliances, and it can stop drafting. Water heaters here also fail the ordinary ways: sediment rumbling in the tank, a worn thermocouple that keeps the pilot from staying lit, a tank bottom that starts to seep. Furnaces quit on flame sensors, igniters and clogged filters.
Cobbs Creek is one of the longer drives in our Philadelphia coverage, since we start in West Deptford, cross the Delaware and work across the city to its western edge. Summer keeps us busy here as well. Philadelphia declared a Heat Health Emergency from Sunday June 22 through Wednesday June 25, 2025, and in heat like that a central air unit or ductless system that ran all season without service tends to fail. Those cooling calls come in on the same line, answered 24/7.
Most called for here
Cobbs Creek repairs, from the basement up
Furnace Repair
Basement gas furnaces stop on dirty flame sensors, cracked igniters and blocked filters, often on the first cold night of fall.
Water Heater Repair
Pilots that will not stay lit, rumbling sediment and weak hot water from gas tanks sharing a flue with the furnace.
Water Heater Replacement
When a tank starts leaking at the bottom, the new one goes in with its venting tested and corrected.
Chimney Liner Installation
A properly sized liner lets a water heater vent safely once the furnace no longer shares the chimney.
Tankless Water Heater Installation
Frees up basement floor space and ends the empty-tank problem, though it needs its own vent and a larger gas line.
AC Repair
Central air condensers working hard through summer heat waves, with weak capacitors and dirty coils at the top of the list.
On a gas tank water heater, it is usually a worn thermocouple or a dirty pilot assembly. Poor draft in the flue can also blow it out, so we test both before replacing anything.
Often, yes. They sit in the same basement and usually share venting, so the tech looks at both. If one needs a part that has to be ordered, we tell you before leaving.
It can be. It saves basement space and does not run out mid-shower, but it needs a larger gas line and its own vent. We check both before pricing the install.
Yes. We work on both sides of the city line, so a house on either side of the creek gets the same service. Call any hour and give us the address.
Leave the house and call 911 or the gas utility from outside. Once the utility has made it safe, we find and repair the cause and test every gas appliance in that basement.
