A blower motor moves air from your furnace through ducts to heat or cool your home. Expect costs from a modest PSC swap to a higher ECM upgrade. Diagnose first, compare part numbers and warranties, and ask for post‑install amp and airflow tests before approving any work. (ASHRAE Technical Resources)
Key Takeaways
- Typical installed costs: PSC swap $250–$650; ECM upgrade $600–$1,500+.
- Always diagnose before replacing; capacitors and bearings often cause failures.
- Ask for part number, warranty, post‑install airflow verification, and amps tested.
