HVAC Warranty Basics
HVAC warranties protect against manufacturing defects, but coverage varies widely. Understanding parts, labor, and transfer conditions helps you pick systems that match your ownership timeline and risk tolerance.
Limited Parts Warranty
This covers parts that fail due to factory defects. Most top brands offer 10-year parts coverage. You must register your equipment within 60–90 days after install.
Heat Exchanger & Compressor Coverage
These are the most costly parts to replace. Furnace heat exchangers and heat pump compressors often have 20-year or lifetime coverage. Labor is not included unless you buy extra protection.
Labor Warranty
Most makers do not cover labor costs. Portland contractors usually offer 1–2 years of workmanship coverage. You can buy extended labor plans for 5–10 extra years of protection.
Transferability
Many brands let you transfer the warranty when you sell your home. There is usually a small fee and a 60-day deadline. This can boost your home's resale value.
Portland Warranty Priorities
Local weather, wildfire smoke, and utility conditions influence warranty value. Plan for corrosion, power quality, and IAQ equipment when evaluating coverage.
Salt Air & Moisture Exposure
Portland's wet winters and nearby coast can cause rust and corrosion. Look for warranties that cover coil coatings. This matters most near the Columbia River or coast.
Wildfire Smoke & IAQ Accessories
Air cleaners, ERVs, and UV lights often have shorter warranties of 1–5 years. Pair them with maintenance plans to protect your investment during smoke season.
Electrification Incentives
Heat pump rebates need proof of proper setup. Keep your warranty papers with your Energy Trust records. This helps avoid issues during audits or when you sell.
Utility Power Quality
Power surges and brownouts can void your warranty. Add surge protectors to keep coverage on motors and inverters. This is critical for PGE customers.

Registration & Documentation
Most warranty problems stem from missed registration deadlines or missing paperwork. Follow these steps to keep coverage intact.
- Collect model and serial numbers for each indoor/outdoor unit, thermostat, and IAQ accessory on installation day.
- Register equipment on manufacturer portals (Trane, Carrier, Lennox, Mitsubishi, etc.) within 60 days. Save confirmation emails as PDF.
- Upload commissioning reports, AHRI certificates, and installer invoices to a secure folder. These documents prove professional installation.
- If selling your home, submit transfer paperwork and fees within the manufacturer’s required window, typically 60–90 days post-closing.
- Log maintenance visits, filter changes, and software updates. Warranty claims frequently request service history, especially for inverter heat pumps.
Extended Warranty & Service Plans
Decide whether to add extended labor coverage, service memberships, or home warranties depending on how long you plan to own the home and the complexity of your HVAC system.

How HVAC Warranty Claims Work
When issues arise, fast documentation and communication keep HVAC downtime minimal. Follow this workflow with your Portland contractor.
1. Diagnose & Document
Contact your installing contractor first. They diagnose failures, capture error codes, and confirm if the issue is covered under warranty.
2. Verify Registration & Maintenance
Provide proof of registration, invoices, and maintenance logs. Expect manufacturers to request filter change or tune-up records before approving claims.
3. Submit Claim & Await Authorization
Contractor files claim with manufacturer portal. Authorization typically arrives within 24–72 hours for major brands; expedite by responding quickly to info requests.
4. Parts Procurement & Labor Scheduling
Once approved, parts ship to the contractor. Labor is billed according to standard rates; extended labor plans cover or reimburse costs depending on program rules.
5. Follow-Up & Record Keeping
After repairs, keep service summaries and shipping records. Update your warranty folder to simplify future claims or home sale disclosures.
