Today, most manufacturers offer a 10-year parts warranty on their equipment with equipment registration. Contractors, on the other hand, typically only offer a 1-year labor warranty. However, the landscape of warranties for HVAC units has changed just a bit with some manufacturers still offer to cover their equipment under a labor warranty but others are now offering these warranties through a third party. We always recommend purchasing an extended labor warranty, particularly the ones backed by the manufacturer. It’s almost a certainty that you will have an issue with your unit within the 10 year period, where in most cases, the warranty pays for itself. However, beware of companies that offer warranties beyond 10 years or even lifetime warranties on labor because, in every case, they have found catch or clause to deny the claim and have forced people to purchase service agreements that require them to complete expensive checkups twice a year. We have also seen many warranty companies go out of business or disappear, without a trace, leaving no one to honor the warranty. On a more positive note, Coleman offers a full, 10 year, no fault parts and labor warranty, through the manufacturer, which means any Coleman dealer can complete warranty service, at no cost to the homeowner.
