This York furnace is built to be one of the most serviceable units in the industry, with a compact cabinet design that fits easily into a variety of residential installation spaces such as basements, closets, alcoves, attics, recreation rooms, or garages. It features redesigned 1/4-turn knobs for quick and easy door removal, along with enhanced safety upgrades including a 100% shut-off main gas valve and a blower door safety switch. Front-facing screws help reduce both installation and service time, while a stainless-steel secondary heat exchanger provides long-lasting performance. Fold-up duct flanges allow for faster, easier connections, and the five-speed, direct-drive ECM blower motor improves SEER2 ratings while using less electrical power. In addition, performance testing shows less than 2% airflow leakage, supporting efficient and reliable operation.
