Furnace Heat Exchanger Warranty — What Is Covered and What Is Not
Published: July 23, 2026 — BC Wide Home Services Ltd, doing business as BC Wide Heating & Air Conditioning — Greater Vancouver, BC
Warranty Types
Heat exchanger warranties come in two types: limited lifetime (covers the original owner for life but usually excludes labour after the first 5-10 years) and standard 20-year (covers the heat exchanger for a fixed period). Both cover the part only — you pay labour.
What Voids the Warranty
No annual maintenance records, installation by unlicensed contractor, operation without a filter, use in a commercial application, flood or fire damage, and modification of the equipment. Keep your annual service receipts to maintain warranty validity.
Filing a Claim
Contact the installing contractor with model/serial numbers. The contractor inspects the heat exchanger and photographs the defect for the manufacturer. Approval takes 1-7 days. You pay labour and the manufacturer provides the replacement heat exchanger or a credit toward a new furnace.
