Indoor Temperature Variation


Inverter Technology
Typical Air Conditioners

Typical air conditioners and heat pumps can cause temperature swings because of their short air cycles that turn on and off in short spurts to adjust to your preferred temperature, much like a driver in stop-and-go traffic.

Inverter Products With SmartSense Technology

Our variable-speed inverter air conditioner and heat pump with SmartSense Technology work much like cruise control—they operate in longer cycles and make many small variations to work more efficiently and deliver continuous comfort.

How is SmartSense Technology different?
Inverter Technology


The Comfortmaker Ion™ 19 Variable-Speed Air Conditioner and Ion™ 18 Variable-Speed Heat Pump are designed for our best energy-saving operation at a cost comparable to a two-stage unit, but can save you more money. Operating much like adaptive cruise control, SmartSense Technology makes many small variations to compressor and fan speed in order to work more efficiently and keep temperatures and humidity in your home steady. Increased savings from higher leaving temperatures in the cooler months and energy-wise dual fuel capability makes our inverter heat pump with SmartSense Technology a money-saver for any homeowner. And when installed as part of an Observer communicating system, both of these products will optimize to run at the most efficient level, saving you money.

Steady, Quiet Comfort

Whether it’s quiet summer days on the patio or fall evenings under the stars, your comfort will stay uninterrupted with Comfortmaker variable-speed inverter products. They run much quieter than traditional two-stage units so your time outside is peaceful. During warmer months, the air conditioner and heat pump run at lower, more efficient speeds the majority of the time, providing your home with superior humidity control and comfort. And during cooler months, the heat pump delivers higher leaving air temperatures for a steady, warming comfort.

Inverter Technology


The Ion™ 19 Variable-Speed Air Conditioner and Ion™ 18 Variable-Speed Heat Pump can be matched with a compatible indoor unit and work with most two-stage units. When installed as part of a complete Ion™ Communicating Control with Wi-Fi®1 capability, your home will not only run at optimal levels, but you can also adjust your preferred home temperatures remotely. That means when you come home from vacation, you can change your home temperature from your remote device so that it will be at the perfect comfort level when you walk through the door.
