Heating & Furnace Repair in Drexel Hill, PA
Drexel Hill's housing is dense — stone twins and rows built largely between the 1920s and 1950s, many still heated by systems installed decades ago and converted more than once. That produces a heating repair profile quite different from the newer suburbs.
PJ MAC is headquartered on Harper Avenue in Drexel Hill, so this is our home market. A person answers the phone around the clock.
Older gas furnaces and the parts that fail
On the gas furnaces common here, the failures cluster tightly: hot surface ignitors that crack and stop glowing, flame sensors that carbonise until the burner lights and immediately shuts down, pressure switches tripped by a blocked flue or a sagging condensate line, and limit switches opening because airflow across the heat exchanger is restricted.
Most of those are inexpensive parts. The diagnostic skill is telling which one actually failed rather than replacing the obvious candidate — a furnace that lights and drops out after a few seconds is a flame sensor or a grounding problem far more often than it is an ignitor.
Party-wall houses and freeze risk
In a twin or row home a heating failure carries a plumbing risk that a detached house does not. Pipes running in exterior and party walls, and in unheated third-floor spaces, can reach freezing quickly once the heat stops in January. That is why we treat a no-heat call in this housing as urgent rather than as something that can wait until morning.
Carbon monoxide
A cracked heat exchanger or a blocked flue in a party-wall building is a safety matter, not just a comfort one. If you have a CO alarm sounding, leave the house and call from outside. We check flue draft and heat exchanger condition on every heating call, whether or not that is what you rang about.
Systems we work on
- ✓Gas and oil furnaces, including older conversions
- ✓Hydronic boilers and radiator systems, still common in this housing
- ✓Heat pumps and their auxiliary heat, where the usual complaint is lukewarm air rather than no heat
- ✓Thermostat and control faults, which mimic equipment failure and are cheap to rule out
Drexel Hill Heating & Furnace Repair — Questions We Get
Do you answer overnight?
Yes — a person answers 24 hours a day, every day of the year, and Drexel Hill is our home market with the office on Harper Avenue. You will get a realistic arrival window rather than an open-ended promise.
My furnace lights and then shuts off after a few seconds. What is that?
That specific pattern is most often a dirty flame sensor. The burner lights, the sensor fails to confirm the flame, and the control shuts the gas off as designed. It is a cheap fix. A cracked heat exchanger or a flue problem can produce similar behaviour, which is why it should be diagnosed rather than guessed.
How urgent is a no-heat call in a twin home in winter?
More urgent than in a detached house. Pipes in party and exterior walls and in unheated upper floors can begin to freeze within hours in a January cold snap, and a burst pipe costs far more than the heating repair. We treat these as same-night calls.
My carbon monoxide alarm went off. What should I do?
Leave the house and call from outside, and call the gas utility if you smell gas. Do not restart the system to test it. A CO alarm in a party-wall building can involve a cracked heat exchanger or a blocked flue, and both need to be verified by someone with a combustion analyser before the appliance runs again.
Do you still work on radiator and boiler systems?
Yes. Hydronic boilers and radiators remain common in Drexel Hill's older housing and we service and repair them alongside forced-air furnaces and heat pumps.
My heat pump is blowing air that feels cool. Is it broken?
Not necessarily. Heat pumps deliver air at a lower temperature than a furnace, so air that feels cool against your skin can still be heating the house. It becomes a fault when the house is not holding temperature or the auxiliary heat is running constantly, and that is worth diagnosing because it shows up on the bill.
