Advantage 5th Gen 12k BTU 115V 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 — 12,000 BTU
The Advantage 5th Gen 12k BTU 115V Condenser 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 21.2 SEER2 and 10.1 EER2 at full load. SEER2 measures seasonal cooling efficiency — higher is better — and 21.2 puts this in the premium efficiency tier. For heating performance it carries a 8.7 HSPF2 rating, which translates to roughly 250–300% 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 136 kWh/month — about $22/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.
Power & Electrical Requirements
Power requirement: 115V 1-phase 60Hz (standard US 120V household outlet). Minimum circuit ampacity is 19A with a maximum overcurrent protection of 20A. Wire the outdoor unit with 12 AWG copper on a dedicated 20A 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 82ft; 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-454B refrigerant. R-454B is the EPA 2025-compliant low-GWP replacement for R-410A, required for new-manufacture equipment — lower global-warming footprint without an efficiency penalty.
Sound Level & Comfort Features
Rated sound output is 54 dB(A) at full operation.
Warranty & Certifications
Manufacturer warranty: 1 Year on parts, 2 Years on the compressor. 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 Mini-Split Condenser.
