What this specific model is sized for, how it installs, how it performs, and what it costs to run.
Room & Space Coverage — 12,000 BTU
The Olympus ENERGY STAR 12,000 BTU 1 Ton Ductless Mini Split Heat Pump Condenser- 230V/60Hz delivers 12,000 BTU of cooling and heating capacity (1-ton class), sized for spaces up to 600 sq ft in standard 8-ft ceiling rooms with average insulation. At this capacity the unit is ideal for bedrooms, home offices, sunrooms, and single-room additions up to the stated square footage. Rooms with one exterior wall and average shading sit comfortably in the middle of the coverage range.
Efficiency & Operating Cost
This unit is rated at 24.6 SEER2 and 13.7 EER2 at full load. SEER2 measures seasonal cooling efficiency — higher is better — and 24.6 puts this in the premium efficiency tier. For heating performance it carries a 10.7 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 117 kWh/month — about $19/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.
Power & Electrical Requirements
Power requirement: 208-230V 1-phase 60Hz (standard US residential 240V service). Minimum circuit ampacity is 3A with a maximum overcurrent protection of 15A. Wire the outdoor unit with 14 AWG copper on a dedicated 15A 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
Operating sound level ranges from 22.5 dB(A) on low to 36 dB(A) on high — the low end is whisper-quiet, below a normal conversation (60 dB) and comparable to a library reading room. Sleep mode automatically raises cooling setpoint 1–2°F over 7 hours to match the body's natural temperature drop and cut overnight energy use. Quiet mode caps fan speed and compressor rpm for an extra 2–3 dB drop in sound output.
Warranty & Certifications
When you register your unit within 60 days of purchase you get 5-year on parts and 7-year on the compressor through MrCool's registered warranty program. AHRI certified — required for most utility rebate and tax credit programs.
What's in the Box & Compatibility
Ships as a Mini-Split with remote control included.
