Below are the HVAC warranty exclusions that most often surprise Canadian homeowners. For each, we’ll note how to protect yourself.
1. Labour Charges (Diagnosis, Removal, Reinstall)
Most manufacturer warranties cover the replacement part itself, but not the skilled time to diagnose the issue, remove the failed component, pick up or ship the part, and reinstall/test the system. Labour can rival the part cost on complex jobs.
Dealer labour warranties, extended service agreements, or Protection Plus plans are how Canadians cap this risk.
2. Routine Maintenance Items & Consumables
Filters, belts, humidifier pads, standard cleaning, and seasonal tune‑ups are viewed as homeowner or maintenance plan responsibilities, not manufacturer defects. Skipping them can also reduce efficiency and shorten equipment life.
Enrolling in scheduled maintenance keeps you compliant with most warranty fine print, requiring annual professional servicing.
3. Refrigerant & System Recharge
Unless specifically stated, the cost of refrigerant (and labour to recover, weigh, leak‑check, and recharge) is usually excluded from basic parts coverage.
Environmental handling rules for refrigerants and specialized licensing add cost; some protection plans partially or fully cover these services when caused by normal wear.
4. Damage from Power Surges, Misuse, or Environmental Events
Manufacturer warranties are limited to defects in materials or workmanship. Damage linked to lightning, power quality issues, floods, corrosion from harsh environments, or using incompatible parts typically falls outside coverage.
Home insurance or an expanded protection plan is your safety net in this case.
5. Lack of Regular Servicing/Improper or Unlicensed Installation (Coverage Void)
Failing to have the unit installed and serviced by licensed, certified HVAC professionals or skipping the annual service required can void or downgrade your warranty. DIY repairs, mixing non‑approved components, or losing documentation are common culprits we see in the field.
Keep dated service invoices and your registration confirmation in one place. And ALWAYS make sure to do annual maintenance with a trusted HVAC professional.
Quick Reference: Covered vs. Not Covered

| Blower Motors / Controls | Typically Covered | Labour extra | N/A | Parts only; labour billed unless plan. |
| Filters / Belts / Pads | Not Covered | Not Covered | Included service item | Consumables changed during maintenance. |
| Refrigerant | Rarely Covered | Sometimes (if plan level includes) | Sometimes | Regulated handling; check plan tier. |
| After‑Hours Emergency Calls | Not Covered | Often Covered | Discounts/priority | Depends on plan tier; see WeCARE options. |
Paperwork Essentials: How to Keep Your Warranty Valid
- Register Promptly: Many brands require online registration within 30–90 days for full parts terms. Miss it, and coverage shortens.
- Document Service: Maintain dated records of professional annual maintenance (digital or paper folder). It’s the #1 proof manufacturers request before honouring claims.
- Licensed / Certified Work Only: Installation and repairs should be performed by qualified, credentialed technicians (e.g., TSSA, HRAI‑affiliated, manufacturer‑approved) to preserve safety and warranty status.
