What this specific model is sized for, how it installs, how it performs, and what it costs to run.

Room & Space Coverage — 40,000 BTU

The 3.5 Ton 42,000 BTU 14 SEER R-410A Multi-Postion Packaged Heat Pump delivers 40,000 BTU of cooling and heating capacity (3.5-ton class), sized for spaces up to 1,750 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

This unit is rated at 13.4 SEER2 and 10.6 EER2 at full load. SEER2 measures seasonal cooling efficiency — higher is better — and 13.4 meets current federal baseline. For heating performance it carries a 6.7 HSPF2 rating, which translates to roughly 200–250% heating efficiency versus resistance electric — one kilowatt-hour of electricity moves three kWh of heat into the space at mild outdoor temperatures. Running the unit 8 hours a day at full load draws roughly 716 kWh/month — about $115/month at the US average $0.16/kWh residential rate. Real-world draw is usually 30–50% lower because inverter compressors modulate down most of the time.

Cold & Hot Weather Operating Range

This system produces rated heating capacity down to 0°F ambient, strong performance for cold-climate applications where a secondary heat source isn't needed for most of winter.

Power & Electrical Requirements

Power requirement: 208-230V 1-phase 60Hz (standard US residential 240V service). Minimum circuit ampacity is 27.8A with a maximum overcurrent protection of 40A. Wire the outdoor unit with 8 AWG copper on a dedicated 40A double-pole breaker (or single-pole at 120V), with a disconnect within sight of the condenser per NEC 440.14.

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. Ships with R-410A refrigerant. R-410A is a mature, widely-serviced refrigerant; service technicians and parts are available at any HVAC supply house.

Sound Level & Comfort Features

Rated sound output is 78 dB(A) at full operation.

What's in the Box & Compatibility

Ships as a Package Heat Pump.

Frequently Asked Questions

Everything you need to know about this product

What size room will the 3.5 Ton 42,000 BTU 14 SEER R-410A Multi-Postion Packaged Heat Pump cool?

At 40,000 BTU this unit is sized for rooms up to 1,750 sq ft under standard 8-ft ceilings with average insulation. Add 10–20% for sun-exposed rooms, poorly insulated spaces, or ceilings above 9 ft.

Do I need a licensed HVAC installer?

Yes — this unit is professionally-installed. The installer needs EPA 608 certification to handle R-410A, plus standard HVAC tools (vacuum pump, manifold gauges, nitrogen kit). Expect a one-day install on a single-zone system, more on multi-zone.

Is this unit eligible for the federal 25C tax credit?

At 13.4 SEER2 this unit may not meet the 25C efficiency threshold — check the current ENERGY STAR CEE tier requirements. Confirm with your tax advisor and save the AHRI certificate from your order confirmation.

How cold can it get outside before this heat pump stops heating?

Rated heating capacity holds down to 0°F. Below that temperature most units continue running but deliver reduced output. Strong cold-climate rating — most US homes will not need backup heat.

What electrical circuit do I need for installation?

208-230V 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.
