120,000 BTU Heating Capacity

The ACiQ AC-F120-80M1D is rated at 120,000 BTU input with an 80% AFUE rating, resulting in approximately 96,000 BTU of heating output. This model is a practical choice for larger residential heating applications when properly matched to the home’s heating load. Furnace sizing should always be determined by a qualified HVAC professional using a proper load calculation. Insulation levels, window area, climate, ceiling height, ductwork, and air leakage can all affect the furnace capacity required for consistent comfort.

ECM Blower and Cooling Compatibility

The AC-F120-80M1D includes a 1 HP ECM blower motor that helps maintain stable airflow as duct-system resistance changes. With five selectable blower speed modes and a nominal maximum airflow rating of 1,950 CFM, this furnace offers the airflow capacity needed for properly matched higher-capacity heating and cooling applications.

This furnace is compatible with properly matched 3.5, 4, 4.5, and 5 ton air conditioning systems at 0.5" external static pressure. The metal centrifugal blower supports dependable air circulation for heating, cooling, and fan-only operation. Actual delivered airflow will vary based on blower-speed selection, air filter type, evaporator coil pressure drop, ductwork design, and total external static pressure.

Low NOx and Fuel Flexibility

The AC-F120-80M1D is a Low NOx furnace with emissions below 40 ng/J. It is factory-configured for natural gas operation and can be converted to propane with the LP conversion kit included with the unit. A qualified HVAC professional must perform propane conversion, gas-pressure adjustment, venting, electrical work, and final system commissioning.

This furnace uses an automatic hot-surface ignition system with a durable silicon nitride igniter, eliminating the need for a standing pilot light. A self-diagnostic control board stores fault-code history and displays diagnostic information through a triple seven-segment display, helping qualified technicians identify operating conditions during maintenance or service.

Designed for Flexible Installation

The AC-F120-80M1D supports upflow, downflow, and horizontal installation configurations, allowing a qualified installer to adapt the furnace to the layout of the home. Its cabinet measures 24.5 inches wide, 33 inches high, and 28.5 inches deep, with a 23-inch supply-air width and a 22-27/32-inch return-air width.

Convenient left- or right-side gas and electrical connections, a removable bottom for side or bottom return-air setups, and flush coil compatibility help simplify system design. The cabinet is engineered for air leakage of less than 1.4% and includes adaptable furnace-to-coil mounting provisions for horizontal and downflow applications.

Long-Lasting Components and Diagnostics

The furnace is constructed with a durable aluminized steel tubular heat exchanger, metal blower wheel, and a silicon nitride hot-surface igniter. Its single-stage design provides straightforward, reliable heating operation, while the ECM blower motor supports efficient airflow management throughout the system.

A self-diagnostic control board records fault-code history and provides diagnostic information through a triple seven-segment display, helping qualified HVAC technicians identify operating conditions during service and maintenance.

Important Installation Information

This furnace is designed for indoor, site-built residential applications and must be installed by a qualified HVAC professional. It requires approved Category I metal venting and is not designed for PVC venting. The furnace is not approved for installation in mobile homes, recreational vehicles, or outdoor locations. Proper gas supply, duct sizing, filtration, combustion air, electrical wiring, venting, and start-up procedures are essential for safe operation and must follow the manufacturer’s instructions and all applicable local codes.

Warranty

Please refer to the manufacturer’s current warranty documentation for complete coverage terms, registration requirements, limitations, and exclusions. Professional installation and compliance with all manufacturer guidelines are required to maintain applicable warranty coverage.
