Ask About Coverage

What to Verify

Use these checks before relying on a warranty claim or extended protection offer.

Manufacturer Warranty

Ask for the exact equipment model number, registration deadline, covered parts, compressor terms, and exclusions before installation.

Labor Coverage

Get labor coverage in writing, including term length, what counts as workmanship, diagnostic fees, trip fees, and transferability.

Maintenance Requirements

Many warranties require routine maintenance records. Keep invoices, filter-change records, and any service recommendations.

Authorization

If a brand warranty depends on dealer status, verify current authorization directly before approving the quote.

Warranty Red Flags

Pause before relying on warranty language when these details are missing.

Only verbal warranty promises are offered, with no written labor term, exclusions, or claim process.
The quote depends on brand authorization, but the authorization is not verified directly with the manufacturer.
The equipment model number, registration deadline, serial number, or maintenance requirement is missing.
A warranty is used to justify a higher price without explaining diagnostic fees, trip fees, transferability, or what happens if the company changes ownership.

Warranty FAQs

Practical questions to ask before approving HVAC work.

What voids an HVAC warranty?

Common risk factors include improper installation, missing maintenance records, unapproved parts, DIY repairs, failure to register equipment, and work by an unqualified or unauthorized party.

Is regular maintenance required?

Often, yes. Many manufacturers require regular maintenance to keep coverage valid. Ask what documentation is required and keep copies of every visit.

What is the difference between parts and labor coverage?

Parts coverage usually comes from the manufacturer. Labor coverage comes from the installing or servicing contractor and should be written separately.

How should I compare warranty offers?

Compare term length, exclusions, registration requirements, transferability, diagnostic fees, trip fees, and whether the warranty is backed by the manufacturer, contractor, or third-party provider.
