Product Features & Fitment

Designed for maximum system efficiency and quiet operation, the Goodman AMST36BU1300 features an all-aluminum tube and fin evaporator coil with high-performance coated fin stock to protect against corrosion. Integrated factory features include an internal TXV metering device for optimized refrigerant flow in cooling and heat pump modes, as well as an R-32 leak detection sensor for A2L safety compliance.

The unit's rigid SmartFrame™ cabinet utilizes screw-less sides and back to prevent exterior condensation in humid environments, paired with glue-less foil-faced cabinet insulation. Installation and servicing are streamlined thanks to a coil mounting track for quick repositioning, tool-less filter access, easy service panels, and compatibility with 3 kW to 25 kW electric heater kits (available without heat or with sequence-controlled nickel-chromium elements of 5, 6, 8, or 10 kW).
