Repair or replace: run the math

The honest read

Leans repair

Fix it — and put the anxiety into maintenance instead. Ask what caused the failure so you're not replacing the same part twice.

• At ~8 years, this gas furnace is inside its typical 15–20-year lifespan — repairs on healthy mid-life equipment usually repay.
• Sanity rule (a screen, not gospel): age × repair cost ≈ $2,400 — under the $5,000 line where replacement math deserves a real look.
• Replacement context: typical Seattle-area gas furnace replacement runs $4,000–$9,000 (Home Comfort Alliance Seattle furnace guide, 2026).

Educational guidance, not a diagnosis or a quote — the real answer needs the failed part's name and your equipment in front of a technician. Lifespans reflect our Greater Seattle service history; market ranges are published figures, not Glendale pricing.
