Usually, an air conditioning system (or a heat pump) only operates at one speed. When the thermostat is set to 78° but it’s 80° in the house, the air conditioner turns on at the only speed it can. When the temperature goes back down to 78° again, the system shuts down.
This happens again and again as the temperature keeps rising after several minutes of remaining stable. The system starts up and runs at full speed, and then it shuts down—and this process wears down components faster than it should have to.
How Variable Speed Settings Make a System Work Better
Variable speed technology was designed to change this constant on-and-off that tends to wear out systems and raise your bills. It makes it so that the system can run at half-speed (with a dual-stage system) or various different speeds depending on your climate needs.
A variable speed system will run more frequently but at a lower setting in order to keep temperatures within one or two degrees of your thermostat settings. The advantages to this include—
- Temperature accuracy – Temperatures stay very close to what you’ve set on the thermostat.
- Lower energy bills – Running the AC at a low speed automatically saves energy.
- Quieter operation – The lower speed setting allows for quieter operation and startup.
How It Works
The way your variable speed system is connected to the compressor allows it to automatically adjust speed as needed. A motor control drive modulates the motor to slow down as needed or speed up to get the temperature to the thermostat setting faster.
Typically, you have the ability to adjust the fan to a low setting if need be. For the most part, however, you can let the system do all the adjusting for you, without any assistance.
