What goes wrong
On oil-fired furnaces, which are still common in parts of Pennsylvania, the list is different: nozzle, electrodes, cad cell, fuel pump pressure, filter and chimney draft. A filter clogged after a delivery stirred up tank sediment is a routine finding.
Heating and cooling around Duncannon
south-central Pennsylvania sits on a fuel boundary. Around Duncannon natural gas serves the built-up areas while propane and oil cover the farms and the properties between them, so we stock for all three.
Agricultural buildings and farmhouses in Perry County often run oversized equipment installed when the building was far draughtier than it is now, which causes short cycling and uneven heat.
What happens when you call
We show you what we found. That matters most when the answer is bad news — a condemned system should come with evidence, not just an assertion.

Furnace Repair in Duncannon — questions
Do you cover Duncannon for furnace repair?
Yes. Duncannon in Perry County is inside our service area and the 17020 postal area is worked by the nearest crew. Call (215) 484-0300 at any hour, including nights, weekends and holidays.
How often should I change the filter?
Check a one-inch filter monthly and change it every one to three months. More furnace failures trace back to a neglected filter than to any other single cause.
Is it safe to keep running a furnace that short cycles?
It is not usually an immediate hazard, but it is wearing out the ignition components and costing you fuel. Worth fixing promptly rather than living with.
My furnace stopped right after heavy snow. Related?
Very likely. High-efficiency furnaces vent through plastic pipe out a sidewall, and snow or ice over that termination stops the furnace firing. Clearing it is often the entire repair.
