What Voids Your Warranty
⚠️ Lack of maintenance:
Most manufacturers require annual professional maintenance. If you can't prove maintenance was performed, warranty claims may be denied. Keep all receipts. See our maintenance checklist.
⚠️ DIY repairs:
Attempting repairs yourself typically voids warranty coverage. Always use licensed professionals.
⚠️ Improper installation:
If original installation didn't meet code or manufacturer specs, warranty may be void. This is why choosing a reputable installer matters.
⚠️ Missing registration:
Many manufacturers require product registration for full warranty. Without it, you may get only a basic 5-year warranty instead of 10.

Extended Warranties: Worth It?
Extended warranties can make sense if:
- You're buying budget equipment
- You want peace of mind
- You plan to stay in your home long-term
They're probably not worth it if:
- You're buying high-quality equipment
- You maintain your system religiously
- The cost is more than 10% of system cost
