Single Speed, Two Stage, & Variable Speed Air Conditioner

When shopping for a new air conditioner, you’ll encounter three main compressor types: single speed, two stage, and variable speed. Here’s what you need to know about each.

Single Speed

A single-speed AC runs at full capacity whenever it’s on. It’s the simplest and least expensive option, but it cycles on and off frequently, which can result in temperature swings and higher energy bills.

Two Stage

A two-stage unit can run at full or partial capacity depending on the demand. On milder days, it runs at lower capacity, saving energy. It’s more comfortable and efficient than a single-speed unit.

Variable Speed

Variable speed compressors can modulate their output continuously to match exactly what’s needed. The result is the most consistent comfort, best humidity control, and highest energy efficiency — with the highest upfront cost.

Which Is Right for You?

For Florida’s climate, a two-stage or variable speed unit is almost always worth the investment. Contact Air & Energy at 941-778-0773 to find the right AC system for your Bradenton home.
