When the heat fails in Upper Darby we would rather hear about it at 11pm than at 8am. A house dropping toward freezing is a plumbing risk as much as a comfort problem, and the repair is the same repair either way.

Describe the symptom rather than the part. Working out which component that points at is our job, and it is faster over the phone than you might expect.

The usual suspects

Furnaces fail in a predictable order. Ignition components first, then airflow problems caused by a filter nobody changed, then control and safety switches, and only occasionally the gas valve or control board that a less careful diagnosis reaches for first.

Heating and cooling around Upper Darby

Around Upper Darby the fuel is usually natural gas, though propane turns up wherever the main stops short. What makes Delaware County distinctive is the age of the buildings: stone farmhouses and pre-war homes that were designed around radiators and later had ductwork threaded through them.

Those retrofits are behind a lot of the comfort complaints we are called about — rooms that never settle, and a system blamed for duct problems.

We will not patch a cracked heat exchanger. It is the barrier between combustion gases and the air you breathe, and the correct answer is replacement — shown to you, with the evidence.

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 Upper Darby — questions

Do you cover Upper Darby for furnace repair?

Yes. Upper Darby in Delaware County is inside our service area and the 19026 postal area is worked by the nearest crew. Call (215) 484-0300 at any hour, including nights, weekends and holidays.

Why does my furnace light then shut off after a few seconds?

Almost always a dirty or failing flame sensor. The furnace cannot confirm a flame, so it closes the gas valve as a safety response. It is one of the least expensive furnace repairs there is.

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.

Can you repair an oil furnace in Upper Darby?

Yes. Nozzle, electrodes, cad cell, pump pressure, filter and draft are standard work for us, not a special order.
