Advantage 5th Gen 9k 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 — 9,000 BTU
The Advantage 5th Gen 9k BTU 115V Condenser delivers 9,000 BTU of cooling and heating capacity (0.75-ton class), sized for spaces up to 450 sq ft in standard 8-ft ceiling rooms with average insulation. At this capacity the unit targets small rooms, nurseries, tiny homes, enclosed porches, and dedicated zones that need precise temperature control without oversizing — oversized units short-cycle, which hurts humidity control and shortens compressor life.
Efficiency & Operating Cost
This unit is rated at 21.5 SEER2 and 12.5 EER2 at full load. SEER2 measures seasonal cooling efficiency — higher is better — and 21.5 puts this in the premium efficiency tier. 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 100 kWh/month — about $16/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: 115V 1-phase 60Hz (standard US 120V household outlet). Minimum circuit ampacity is 18A 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 52.5 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 highly efficient 5th Generation 9k BTU 115V Advantage condenser is a powerful, eco-friendly mini-split unit that allows you to directly control the temperature of the space it’s installed in. This system must be installed by an HVAC professional, but since it is a ductless system, the process is much less time consuming and expensive than a central system! With the capacity to achieve up to a 21.5 SEER2 rating and an HSPF2-4 of 9.0, this system will decrease energy usage while increasing how much money you save. This new generation uses R-454B refrigerant instead of R-410A, making it a much more sustainable and environmentally friendly choice, as R-454B has a GWP (global warming potential) that is nearly 80% lower than the previous refrigerant. Because of this, you can save the world just by sitting and enjoying perfect comfort in your living room! Able to cover spaces up to 400 sq.ft., the Advantage is perfect for those in need of a quiet, convenient, and proficient system that gives you all the features you need. One of those features is the Wi-Fi control module, which simplifies system setup and gives you access to operate your system through your phone and Amazon Alexa or Google Assistant. On top of these features, the Advantage has a 1 year on parts, 2 years on the compressor, meaning you can rest easy in perfect comfort knowing we’ve got your back. The 5th Generation 9k BTU Advantage condenser is clearly the right choice for anyone in need of efficient and practical comfort.
