SHORT DESCRIPTION

Advantage 5th Gen 18k BTU 230V Condenser

LONG DESCRIPTION

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 2 year parts warranty and a 1 year compressor warranty on this unit. Let the 5th Generation 18k BTU Advantage condenser give you the comfort you deserve at the price point you want.
