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 Multi-Position 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.
