Home Warranties questions, answered by experts

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

Because they are considered cosmetic issues, refrigerator door dents are not traditionally covered by a manufacturer's appliance warranty. However, most brands will cover dents discovered upon delivery.

Reputable home warranty companies don’t have hidden costs, but it is important to understand the structure of your agreement and home warranties in general before signing up for one. The most significant and predictable cost you’ll incur is the monthly price. In addition to that, you’ll have to pay the service fee—an average of $85—every time you need to call in a professional for a repair or replacement. The service fee is usually much less than the repair or replacement would otherwise cost, but it’s worth considering in your total.

The cost to install a standby generator is considerable, but they usually come with a warranty. The number of years this is valid for and what it covers will vary. Typically, they last between two and five years, but they don’t normally cover annual services and tune-ups.

Many contractors offer warranties for their repair work. Confirm terms before hiring.
