Beyond Quiet

This heat pump has been engineered with a variable-capacity compressor which allows it to primarily run in low speed—drastically minimizing the sound of air kicking on or off inside the home. Add in a special sound-dampening system to absorb outdoor noise and you can be assured it operates at a noise level that is, quite simply, unheard of.

Smarter Together

With the help of the iComfort® S30 ultra smart thermostat, the SL25XPV heat pump unlocks a world of connectivity. It stays finely tuned to your home by using sensors to react, diagnose, and troubleshoot—all while remaining in constant contact with your dealer to ensure proactive responses. While you’re away, your thermostat can automatically change the temperature of your home to a more energy-efficient setting through Smart Away™ mode to save energy and money. And the system even responds to the outdoor environment to adjust operation to account for factors like pollen and outdoor air quality.

Not air conditioner, but air cooler

June 05, 2024

I am disappointed with the unit's ability to remove the humidity from the air. The humidity on my first floor hovers around 60% (+ or - a couple degrees). My 17-year old Trane is in the upper 40% level.
