If you're reading this from the comfort of your home, there's a good chance your space is being cooled or heated by a split system. This is the most common type of air conditioning system, and for good reason—it’s efficient, effective, and flexible for a wide variety of home layouts.

In this post (and the video below), we’ll walk you through how split systems work, the different types available, and how to choose the right system for your home.

What Is a Split System?

Split systems get their name from the fact that the components are—quite literally—split between an indoor and outdoor unit.

The outdoor unit (also called a condenser or compressor) is responsible for compressing refrigerant and pumping it to the inside.
The indoor unit works with the refrigerant to produce cooled or heated air, which is then delivered throughout your home via a duct system.

This design makes split systems incredibly efficient and adaptable to most residential HVAC needs.

How to Determine What Size Split System You Need

The easiest way to determine what kind of split system you need is to look at the data stickers on your current indoor and outdoor units. You can usually find them on the side of your units or, if a furnace, inside the cabinet door.

How to Choose the Right AC System for Your Home

Choosing the right system depends on a few key factors:

✔ Home Size & Layout

Larger homes may require a central air system, while smaller spaces or add-ons could benefit from a single-zone mini split.

✔ Ducted vs. Ductless

Homes with existing ductwork may lean toward central systems, but ductless options are a perfect solution for homes without ducts.

✔ Energy Efficiency

Look for high SEER-rated systems to save on energy costs in the long run.
