What to Look For in an Heat Pumps

Comfort Features

Heat pumps vary in the number of stages or speeds they offer. Different speeds, or stages, can affect your comfort and the consistency of indoor temperature. The most basic is a single-stage heat pump, with airflow on or off, which can cause fluctuations to your indoor temperature and comfort. Two-stage models offer high- and low-stage heating and cooling to more efficiently heat or cool your space when outdoor weather changes to very cold or very hot conditions. These advanced features can provide more consistent comfort levels than a single-stage model. Premium, variable-speed heat pumps have multiple stages for more precise temperature control and more consistent comfort.

Humidity Control

One way to dramatically improve your home’s comfort is to keep indoor humidity levels steady throughout the year. Two-stage and variable speed heat pumps provide better control because they operate for a longer period of time at lower speeds and use less energy. These pull more humidity out of the air than models with a single-stage compressor.

Sound Performance

Variable-speed and two-stage models provide ultra-quiet operation compared to models with single-stage compressors. In addition, heat pumps that include sound blankets and our Silencer System II™ design can further reduce sound levels.

Energy Saving

Heat pumps are rated by their Heating Seasonal Performance Factor (HSPF), their Seasonal Energy Efficiency Ratio (SEER) and their Energy Efficiency Ratio (EER). These ratings are similar to miles per gallon (MPG) for a car: the higher the rating, the more energy-efficient the system.
