Types of Air Conditioner and Heat Pumps

Single Stage (standard)

A single-stage air conditioner only has one motor speed. Consequently, the air conditioner is operating at its full, 100 percent capacity at all times. When the room reaches the desired temperature on the thermostat, the air conditioner motor will turn off and cease to push and blow cool air through the ducts and vents of the home. When the room temperature rises above the thermostat setting, the air conditioner turns back on again to disburse cool air through the home's ductwork system and vents.

Two- Stage

A two-stage air conditioner uses two motor speeds to blow cool air into rooms. The motor will run at 100 percent of its capacity or around 67 percent of its capacity. When it is blowing at 100 percent, that is the second stage; the 67 percent capacity is the first stage. The air conditioner is signaled which stage to use by the thermostat. For example, if you have been away from home and turned the air conditioner off, the thermostat will signal the air conditioner to use the second, full-capacity stage to cool the home quickly and reach the desired temperature set on the thermostat. Once the desired room temperature is reached, the thermostat will signal the air conditioner to drop down to the first stage

 

What is a SEER?

Each type of system also has a Seasonal Energy Efficiency Rating (SEER). The higher the SEER rating, the more efficient the air conditioner and the more money you save on electricity.
