Bryant

Bryant documents the Evolution 987M as a modulating gas furnace with a variable-speed ECM blower rated up to 98.5 percent AFUE, backed by a lifetime heat exchanger warranty on registration.

Bryant publishes a product page for its 987M gas furnace. This entry records what that page states about the furnace's efficiency, modulation, blower motor, and registered warranty coverage.

987M efficiency, modulation, and blower

Bryant's 987M product page states the furnace reaches up to 98.5 percent AFUE. Bryant describes precise gas modulation that delivers the right amount of heat for energy efficiency.

Bryant's page lists a variable-speed constant airflow ECM motor, which it says provides quiet performance and even-temperature comfort. The efficiency figure, the modulation description, and the blower type are recorded as written on Bryant's product page.

Warranty terms as documented

Bryant's 987M page states a lifetime limited warranty on the heat exchanger upon timely registration, reduced to 20 years if the unit is not registered within 90 days. The page states a 10-year parts limited warranty upon registration, reduced to 5 years without timely registration.

Bryant's page also states a Red Shield 10-year unit replacement warranty covering heat exchanger failure only, upon timely registration. The warranty terms are recorded as written on Bryant's product page and are conditioned on registration.
