Pure comfort at a cost that can’t be beat, the 5th Generation 12k BTU 230V Advantage condenser is the right choice if you want practical, effective heating and cooling. This highly efficient system is able to achieve up to a 21.3 SEER2 rating, as well as a rating of 9.1 HSPF2-4, making it a great choice for anyone who wants to experience ideal comfort without paying a high price for it. Once the Advantage condenser is installed by an HVAC professional, which is a relatively simple process that won’t take long or cost much thanks to the system being a ductless mini-split, you’ll be able to enjoy comfort that’s quiet, convenient, and cost-effective.
This system, which can cover spaces around and up to 550 sq. ft., operates more effectively than its previous generation because it uses R-454B refrigerant instead of R-410A, making it better for the environment and your wallet. To elaborate, R-454B has a GWP (global warming potential), that is around 80% less than the previous refrigerant we used, meaning your carbon footprint will shrink right alongside your electrical bills. This practical system enhances the user experience greatly by including a Wi-Fi module. With this, you can control the temperature of your space using your phone and Amazon Alexa or Google Assistant. The Advantage includes a robust 1-year parts and 2-year compressor warranty with added eligibility for the MRCOOL® Care Program for extra peace of mind. The right HVAC unit, like this 5th Generation 12k BTU condenser, will definitely put you at an Advantage.

Manufacturer Warranty
Covered by MRCOOL's limited warranty. Warranty terms are set by MRCOOL and differ by product line — whether registration is required, and whether the installation has to be performed by a state-licensed HVAC contractor, is not the same across the range. In every case coverage depends on the unit being installed according to MRCOOL's instructions and all applicable codes and permits. MRCOOL's warranty document for this model is the controlling source; ask us and we'll send you the one that applies.
Professional Installation Recommended
Most HVAC equipment must be installed and connected by a licensed professional to remain safe, code-compliant, and eligible for manufacturer warranty coverage. If you're unsure about installation requirements, contact us before you order.
Make sure it is the right size, and that you have the rest of it
Most outdoor units ship alone. If you are not certain of the capacity, or of what has to go with this unit, these two will work it out with you.
Still deciding on the right equipment?
Our HVAC specialists can help you confirm sizing and compatibility before you buy.
