West Mifflin Furnace Repair Service

Most furnace breakdowns announce themselves early: a furnace that clicks but never lights, cycles on and off every few minutes, or blows lukewarm air is asking for attention before the first hard freeze. West Mifflin homeowners call us for honest furnace diagnostics on gas, oil, and electric systems — repaired same-day whenever parts allow. Around Pittsburgh that includes mill-town housing along the rivers, streetcar-suburb twins, and hillside homes with furnaces in stone cellars.

  • Banging, scraping, or squealing from the cabinet
  • The blower runs constantly and never shuts off
  • Rising gas or oil usage with no change in thermostat habits

What's Included

  • Ignition system repair — hot surface igniters, spark modules, pilots

  • Inducer motor and pressure-switch faults
  • Limit switches, thermostat circuits, and control boards
  • Heat exchanger inspection with carbon monoxide testing

What Does Furnace Repair Cost in West Mifflin?

Common furnace repairs — igniters, flame sensors, capacitors — are typically inexpensive parts with quick labor. Inducer motors, blower motors, and control boards cost more. A cracked heat exchanger on an older furnace is usually the tipping point toward replacement, since the part often costs nearly as much as a new unit. You'll get honest numbers either way.

Furnace Repair in West Mifflin — FAQs

My furnace won't turn on at all — what should I check first?

Before calling: confirm the thermostat is set to Heat and calling above room temperature, check the furnace switch (it looks like a light switch near the unit), check the breaker, and make sure the filter isn't fully clogged and the front panel is seated. If those are fine, the fault is likely internal — igniter, pressure switch, or board — and needs a technician.

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

That's usually a dirty flame sensor — a $15 part that keeps half of Pennsylvania warm. The furnace lights, the sensor can't confirm flame, and the board shuts gas off for safety. It can also be a blocked flue or a failing pressure switch. It's one of the fastest, cheapest repairs we do.

Do you repair oil furnaces in West Mifflin?

Yes. Oil heat is still common in Pennsylvania, especially in homes off the gas grid. We service oil burners — nozzles, electrodes, fuel filters, cad cell sensors, pumps — and can also quote oil-to-gas or oil-to-heat-pump conversions if you're weighing a switch.

Should I repair or replace a 20-year-old furnace?

A 20-year-old furnace is on borrowed time — typical lifespan is 15–20 years. A small repair to limp through a season can be reasonable, but a major one rarely is, especially when a new 95%+ AFUE furnace cuts fuel use significantly. We'll price both so you can decide with real numbers.

My mill-town house has radiators — who actually works on these anymore?

Fewer companies than there should be, which is exactly why we vet for it. Steam and hot-water systems are common across the Mon Valley and older Allegheny County boroughs, and our network includes technicians who service boilers, circulators, steam vents, and zone valves routinely — not as a sideline.
