Most home air conditioning systems are split systems, meaning they have two constituent units. The outdoor unit houses a condenser that ejects hot air and contains connective refrigerant tubing. The indoor unit, known as the air handler, disperses cool air through the vents in your home. When you're upgrading your HVAC components or installing a new system, you can get either a single-speed or a variable-speed air handler.

Variable-speed air handlers offer several advantages over single-speed systems. Whereas single-speed systems always run on "high," a variable-speed air handler offers a range of settings, which can reduce your power use -- and your utility bills. If you need to cool down your house only a little bit, you can use a lower setting, which draws less energy.

Other advantages of a variable-speed A/C:

- It's quieter.
- It produces no sudden blasts of cold air through your vents. The system reaches your desired temperature gradually.
- It's better at combating humidity.

Finally, variable-speed air handlers are easier to work with in households with zoned climate systems, which allow pinpoint control over different rooms or stories in your home. Zoned systems allow you to maximize energy savings and extend the life of your HVAC system.
