Operating Temperature Range
Customer Reviews
We put this 18K unit in our 1200 sq ft open living/dining area and it works out beautifully. The 23.5 SEER2 rating is not just some marketing hype - our energy bills dropped significantly. Even during that cold snap at -5°F, it kept us warm without any backup heat. The quiet mode is incredibly silent and the turbo mode cools the space down in minutes.
We live in Maine, so we needed a heat pump that could actually handle our winters. This 18,000 BTU unit has been a lifesaver - it maintained 70°F inside when it was -10°F outside. The premium compressor is clearly high quality. The dehumidification feature during summer is fantastic too - removes moisture without over-cooling.
I'm an HVAC contractor and have installed over 100 mini-splits. This unit is seriously impressive - the build quality is on par with brands that cost twice as much. The 65 ft maximum line length gives us a lot of flexibility for installations. The premium motor is reliable, the pre-charged line sets make installation faster, customers love the quiet operation and energy savings.
We added a 1200 sq ft family room and didn't want to take our existing HVAC out of commission. This 18K unit was the perfect solution. Heating and cooling are both excellent. The smart sleep mode is great - gradually adjusts temperature overnight so we wake up comfortable every morning. Installation with a 208V connection was straightforward for our electrician.
After researching extensively, I chose this unit for the 23.5 SEER2 rating and the cold climate certifications. Three months in and it's been flawless. The variable speed operation keeps temperatures rock solid without the on/off cycling of cheaper units. We got an Energy Star rebate from our utility that covered a good chunk of the installation. Highly recommend!
