Advantage 5th Gen 18k BTU 230V 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 — 18,000 BTU
The Advantage 5th Gen 18k BTU 230V Condenser delivers 18,000 BTU of cooling and heating capacity (1.5-ton class), sized for spaces up to 900 sq ft in standard 8-ft ceiling rooms with average insulation. At this capacity the unit handles medium primary rooms, master suites with attached bath, converted garages, and workshops. If your space includes a sunny west-facing wall or a finished bonus room above it, lean toward the upper end of the coverage range.
Efficiency & Operating Cost
This unit is rated at 19.2 SEER2 and 10.8 EER2 at full load. SEER2 measures seasonal cooling efficiency — higher is better — and 19.2 meets modern federal minimum standards with headroom for utility rebates in most states. For heating performance it carries a 9.6 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 225 kWh/month — about $36/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: 208-230V 1-phase 60Hz (standard US residential 240V service). Minimum circuit ampacity is 15A 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 98.4ft; 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 56 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.
Product Details
The 5th Generation 18k BTU 230V Advantage condenser is the right choice for anyone who needs fast, efficient, and effective home comfort. While this ductless mini-split unit must be installed by an HVAC professional, it’ll be a much cheaper and faster process than a typical installation of a central system, as it is a ductless mini-split unit. It’ll also be worth it because this system is incredibly convenient and user-friendly, thanks to features like its Wi-Fi Module! This feature enables integration with your phone and allows you to use Amazon Alexa and Google Assistant, which lets you literally speak your comfort into existence. When it comes to its operation, this system uses significantly less energy than its previous generation because it uses R-454B instead of R-410A. R-454B has around 80% less of a GWP (global warming potential), which allows the system to be much more eco-friendly, reducing your carbon footprint while you enjoy perfect comfort. Use of this refrigerant also enhances the efficiency of this system, so this condenser can achieve up to a 19.2 SEER2 rating and a 9.3 HSPF2-4 rating. This system is perfect for a space that is up to and around 800 square feet. We’ve got your back when it comes to this unit, too. Once you register, you are entitled to a 1 year on parts, 2 years on the compressor on this unit. Let the 5th Generation 18k BTU Advantage condenser give you the comfort you deserve at the price point you want.
