SHORT DESCRIPTION |
Advantage 5th Gen 9k BTU 230V Condenser |
LONG DESCRIPTION |
We’re excited to announce our 5th Generation 9k BTU 230V Advantage condenser, which is a sustainable and economic system ready to provide the comfort you need and deserve. This system can achieve up to a 21.2 SEER2 rating as well as an HSPF2-4 of 9.1 thanks to its incredibly innovative design. This system, which must be installed by an HVAC professional, utilizes a much more environmentally friendly refrigerant than R-410A, which its previous generation used: R-454B. This choice ensures that the unit operates efficiently and effectively throughout its entire lifespan, reducing your carbon footprint in the process due to the GWP (global warming potential) of R-454B being almost 80% lower than its predecessor. If you need a system for a space around or up to 400 sq. ft. that is convenient, quiet, and chock full of features that create an ideal user experience, the Advantage 9k will be perfect for you. This system comes with a Wi-Fi module that, when installed, allows you to control the temperature of your room through your phone and Amazon Alexa or Google Assistant. You won’t even have to lift a finger to experience the best comfort you’ve ever felt! Once registered, the Advantage has a 2 year parts warranty and a 1 year compressor warranty, so you can rest easily with the knowledge that we’ve got your back and your comfort! The 5th Generation 9k BTU Advantage condenser truly lives up to its name when it comes to perfect, efficient, interior comfort! |
