SHORT DESCRIPTION

Advantage 5th Gen 12k BTU 230V Condenser

LONG DESCRIPTION

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 500 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 warranties, which are a 2 year parts warranty and a 1 year compressor warranty, will protect your peace of mind as you enjoy the perfect temperatures for you! The right HVAC unit, like this 5th Generation 12k BTU condenser, will definitely put you at an Advantage.
