4-5 ton up to 18 SEER Universal Series Condenser — Model Details
What this specific model is sized for, how it installs, how it performs, and what it costs to run.
Room & Space Coverage — 48,000 BTU
The 4-5 ton up to 18 SEER Universal Series Condenser delivers 48,000 BTU of cooling and heating capacity (4-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
This unit is rated at 17 SEER2 and 11 EER2 at full load. SEER2 measures seasonal cooling efficiency — higher is better — and 17 meets modern federal minimum standards with headroom for utility rebates in most states. For heating performance it carries a 9 HSPF2 rating, which translates to roughly 300–350% 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 678 kWh/month — about $108/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. ENERGY STAR certification makes this SKU eligible for federal tax credits (25C in 2026, up to 30% / $2,000 for qualifying heat pumps) and most state/utility rebate programs — check your state page for specific amounts.
Cold & Hot Weather Operating Range
This system produces rated heating capacity down to -2275.2°F ambient, putting it in hyper-heat territory suitable for northern climates where ducted gas is the usual backup. On the cooling side the compressor runs down to 5129.2°F outdoor ambient, useful for server rooms, grow rooms, and any space that needs year-round cooling.
Power & Electrical Requirements
Power requirement: 208-230V 1-phase 60Hz (standard US residential 240V service). Minimum circuit ampacity is 35A with a maximum overcurrent protection of 45A. Wire the outdoor unit with 6 AWG copper on a dedicated 45A 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. The system supports line set lengths up to 1645ft; longer runs are available as accessory kits. Plan the shortest practical route — every 10ft of line set adds roughly 2% capacity loss. 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 58 dB(A) at full operation.
Warranty & Certifications
Manufacturer warranty: 5 year limited extended parts warranty on parts. AHRI certified and UL/ETL listed for North American electrical safety — required for most utility rebate and tax credit programs.
What's in the Box & Compatibility
Ships as a Universal Series Heat Pump.
