GMVM97 efficiency, gas valve, and blower

Goodman's GMVM97 specification sheet titles the unit a Modulating, Variable-Speed ECM Gas Furnace rated up to 98 percent AFUE. In Goodman's product specifications table, individual GMVM97 configurations list AFUE values of 98 and 97 depending on model.

Goodman's feature list describes a self-calibrating modulating gas valve that auto-configures for each installation. The same document lists a variable-speed ECM circulator blower. Goodman describes a heavy-duty aluminized-steel tubular primary heat exchanger and a stainless-steel secondary heat exchanger.

Warranty terms as documented

Goodman's GMVM97 spec sheet states that, with online registration completed within 60 days of installation, the furnace carries a Lifetime Heat Exchanger Limited Warranty good for as long as the owner owns the home. The document states the same registration unlocks a 10-Year Unit Replacement Limited Warranty and a 10-Year Parts Limited Warranty.

Goodman's document notes that online registration is not required in California or Quebec. The warranty terms are recorded as written on the specification sheet.
