What this specific model is sized for, how it installs, how it performs, and what it costs to run.
Room & Space Coverage — 44,000 BTU
The 96% AFUE 3 Ton 45,000 BTU Downflow Multi-Speed Gas Furnace delivers 44,000 BTU of cooling and heating capacity (3-ton class), sized for spaces up to 2,000 sq ft in standard 8-ft ceiling rooms with average insulation. At this capacity the unit is typically used for open-plan main floors, large garages, pole barns, finished basements, and small commercial bays. For homes with vaulted ceilings, heavy sun exposure, or poor insulation, plan on ~20% more BTU per square foot than the nominal coverage.
Efficiency & Operating Cost
On the gas side the unit achieves 96% AFUE, meaning 96¢ of every fuel dollar becomes usable heat — the rest exits through the flue.
Power & Electrical Requirements
Power requirement: 120V 1-phase 60Hz (standard US 120V household outlet).
Install Difficulty — Professional Install
This is a professionally-installed condenser that requires a licensed HVAC technician with EPA 608 certification. The tech will pull a vacuum on the line set to 500 microns, pressure-test with nitrogen, release the factory charge, and commission per MrCool's startup procedure. Budget 1 full day for install on a single-zone system.
What's in the Box & Compatibility
Ships as a Gas Furnace.
Product Details
The MRCOOL® Signature Series Single-Stage 96% AFUE 45k BTU is a quiet-running and energy efficient downflow furnace unit that provides superior heating performance in a compact design. Thanks to the multi-speed high efficiency blower motor, the furnace features a 96% AFUE, and offers enhanced cooling SEER ratings when applied with properly matched cooling equipment, so utility costs will be more affordable. The unit’s durable build and finish is credited to an aluminized steel primary heat exchanger with crimped non-welded construction. For smooth ignition, the furnace features aluminized steel inshot burners and a durable silicon nitride ignitor. The single stage gas valve delivers home heating quickly and effectively. Installation is easy thanks to the unit’s compact 33 inch design and its standardized widths for easy coil fit. It can be easily vented with PVC pipe and offers a left or right utility connection. It is design certified for direct and non-direct vent applications. There is also an optional LP kit for liquid propane conversion if needed. The easily removable slide out blower design makes maintenance a breeze for a professional HVAC technician as well. For peace of mind, MRCOOL® backs this product with a lifetime heat exchanger warranty in addition to a 10-year parts warranty.
