Single Stage Heat Pump Vs. 2 Stage

Hot summer days can be more comfortable with a heat pump.

A heat pump is a furnace and air conditioning system provided in one unit. Heat pumps monitor the air temperature outside your home and provide either warm or cool air depending on preset conditions. Many manufacturers use two-stage heat pump technology that allows the unit to operate at a high level on warm summer days and a low level during milder weather, improving performance over single-stage devices.

Steady Temperature

A two-stage system operates on its low setting a majority of time to meet your home's cooling needs. This provides a more steady flow of air, resulting in more even temperatures throughout the home.

Humidity Control

Two-stage heat pumps remove twice the amount of humidity from the air compared to single-stage models. Increased moisture removal is beneficial in the reduction of mold and other humidity-related problems.

Operating Noise

Because a two-stage heat pump often cools your home on its low setting, the unit operates at a quieter level and is more efficient than a single-stage system.
