What Is an HVAC Warranty?
An HVAC manufacturer’s warranty is an agreement that the manufacturer of a product will cover any necessary repairs and replacements for a specified period. Most manufacturer warranties cover defective parts for up to 10 years, but do not cover labor or installation costs.
Your HVAC warranty is more than just fine print — it’s your safety net when something goes wrong. But here’s the thing: one missed maintenance visit, a lost receipt, or a simple paperwork slip-up can leave you footing the bill. The good news? With a little know-how (and a trusted HVAC partner), you can keep your coverage intact and your home comfortable for years to come.
There are several benefits to having a system or appliance warranty. For example, if your air conditioning suddenly stops during a heat wave, a warranty can help you find a covered technician and avoid out-of-pocket repair costs.
Types of HVAC Warranties
Not all warranties are the same. Most homeowners will have one or more of these:
- Manufacturer’s Warranty – Covers defects in parts such as compressors, coils, and motors. Typical coverage lasts 5–10 years.
- Installer/Contractor Warranty – Covers the quality of the installation itself. Usually 1–2 years, but it varies by contractor.
- Extended Warranties – Add extra years of coverage for parts and sometimes labor.
Example: Hillside’s Elite Diamond Contractor status with Mitsubishi lets us offer an exclusive 12-Year Extended Warranty — far beyond what most companies can provide.
What’s Covered
Warranties generally protect you against unexpected part failures, such as:
- Compressors
- Condenser and evaporator coils
- Blower motors
- Certain electronic components
Some warranties also include labor — but always read the fine print to be sure.
What’s Not Covered
It’s just as important to know what’s not included:
- Improper installation by an unqualified contractor
- Skipped or irregular maintenance
- Normal wear and tear
- DIY repairs or modifications
- Using non-approved parts
Protecting Your Warranty
1. Save Your Documents Safely
Your warranty isn’t much good if you can’t prove it exists. Keep:
- Warranty paperwork
- Proof of purchase/installation
- All maintenance records
Store these in a home binder, fireproof safe, or digital cloud folder. If you ever need a repair claim approved, having these handy can be the difference between full coverage and a big bill.
2. Don’t Break the Warranty
- Use licensed, certified HVAC technicians.
- Follow the maintenance schedule exactly.
- Avoid any unauthorized changes to your system.
3. Where to Find Warranty Info in an Existing Home
If you’ve moved into a home with an HVAC system already installed:
- Check the owner’s manual or inside the unit’s access panel.
- Look for a warranty sticker or card.
- Contact the manufacturer with the unit’s serial number to confirm coverage.
4. Does the Warranty Transfer?
Many manufacturer warranties can transfer to a new homeowner — but only if you register it within a set timeframe (often 30–60 days after closing). If you’ve just bought a home, contact the manufacturer immediately to keep the coverage.
Why Maintenance Matters
Skipping maintenance is one of the fastest ways to void your warranty. Most manufacturers require documented annual service by a qualified professional. Our maintenance plans make it simple — we handle the scheduling, service, and recordkeeping so your warranty stays protected.
