Peace-Of-Mind Performance

Reduced Emissions

Households generate 72% of greenhouse gas emissions, so switching to a heat pump can make a big difference for the environment-today

Energy Savings

Energy Savings

Just like a vehicle’s MPG rating, the higher the SEER2, EER2 and HSPF2 rating (Seasonal Energy Efficiency Ratio / Energy Efficiency Ratio / Heating Seasonal Performance Factor), the higher the efficiency of your heat pump-resulting in more energy savings. Keep in mind, other factors such as system matching, sizing, ductwork and installation also impact the overall efficiency. By working with a properly trained contractor, you can be confident that you are choosing the best heating and cooling system for your home’s comfort-and your finances.

Durable Curb Appeal

Durable Curb Appeal

Curved louvered panels and rugged corner posts provide excellent protection to internal components, while modern cabinet aesthetics including the corrosion-resistant composite base pan and powder coat paint system allow your unit to put its best face forward for years to come.

Precise Comfort

Maximum Comfort

Inverter driven, variable speed compressor technology features cooling operation between 40% and 100% of capacity (with overdrive capability up to 115% in extreme conditions) to continuously meet your ever-changing heating and cooling needs. You’ll enjoy exact temperature and advanced humidity control that combine to exceed your optimal comfort expectations.


Among Heat Pumps, This One’s A Star

Earning ENERGY STAR® recognition means products meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency. ENERGY STAR certified heating and cooling equipment can enhance the comfort of your home while saving energy-which saves money on utility bills and protects our climate by reducing harmful carbon pollution and other greenhouse gases.

Quiet Operation

Quiet Operation

Efficient home comfort shouldn’t be noisy. That’s why our heat pumps are designed with acoustics in mind. Sound-dampening features such as refrigerant tubing design, fan blade approach, composite base pan and innovative compressor and drive technologies ensure that as efficiency goes up, sound levels stay low.
