14 SEER 3.5 Ton Louvered Packaged Air Conditioner — Model Details
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 14 SEER 3.5 Ton Louvered Packaged Air Conditioner 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. 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 27.5A 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 AC.
