What does furnace repair typically cost in Upper St. Clair?

Repair costs vary by issue. Simple adjustments and sensor replacements can start under $250, while more extensive repairs like heat exchanger work may range up to $2,500. We provide detailed estimates before any work begins.

How long will a furnace repair take?
