Single Speed, Two Stage, & Variable Speed Air Conditioner

When shopping for a new AC system, you’ll encounter three types of compressor technology: single speed, two stage, and variable speed. Here’s what each one means.

Single Speed

Single speed systems run at full capacity or not at all. They’re the most basic and least expensive option, but they cycle on and off frequently, which can cause temperature swings and higher humidity.

Two Stage

Two stage systems run at two levels — typically 65% and 100% capacity. They run longer at the lower stage, providing better humidity control and more consistent temperatures.

Variable Speed

Variable speed systems continuously adjust their output from very low to full capacity. They’re the most efficient, provide the best comfort, and control humidity exceptionally well. Contact Air & Energy at 941-778-0773.
