Some of our products are sold through wholesale distribution. All warranty claims require the model and serial number of the unit be provided to verify warranty eligibility. Many parts on our units are common and universal in design such as oil burner parts. The distributors stock many of these parts that can be used on our units. They also stock many Thermo Products specific parts as well. Most distributors will sell and invoice the repair part to the contractor and then process the warranty claim on their behalf. The selling price of a repair part is often more than the manufacturer's credit amount. This difference is the responsibility of the contractor.
All warranty returns and claims must go through an authorized Spirit Furnace contractor. No Warranty claims will be accepted from homeowners. For prompt warranty services, please notify the installer who will submit the warranty claim to Thermo Products, LLC.
