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.

Frequently Asked Questions

Everything you need to know about this product

Do I need a licensed HVAC installer?

Yes — this unit is professionally-installed. The installer needs EPA 608 certification to handle the refrigerant, plus standard HVAC tools (vacuum pump, manifold gauges, nitrogen kit). Expect a one-day install on a single-zone system, more on multi-zone.

What electrical circuit do I need for installation?

120V dedicated circuit with the disconnect within sight of the outdoor unit per NEC 440.14. An electrician will size the breaker based on the minimum circuit ampacity shown on the nameplate. Budget $400–$900 for a new dedicated 240V circuit if one isn't already present.

What if it arrives damaged or I change my mind?
