Take Charge of Your Home Climate

  • Protect Your Wallet: Eliminate the high labor fees of traditional HVAC installation. The Quick Connect® line sets are pre-charged and secure easily. You do not need vacuum pumps or special trade skills.
  • Eliminate Hot Spots: The "Follow Me" remote function ensures the temperature is right where you stand. The system works hard to balance the air across large rooms.
  • Weather-Proof Comfort: It warms your home when it is -13°F and keeps it cool when it reaches 122°F. Harsh forecasts will not disrupt your indoor environment.
  • Quiet Power: Despite its high capacity, the system stays unobtrusive. You get massive airflow without the distracting roar of older units.
