What Is a Split HVAC System and How Does It Work?
If you've ever heard the term split system and wondered what it means, you're not alone. At Estes Services, we're here to help Atlanta homeowners understand their options when it comes to heating and cooling systems — and how to choose the one that keeps your home comfortable year-round.
What Is a Split System?
A split HVAC system is one of the most common types of heating and cooling setups for residential homes. It's called a "split" system because it has two main components:
An outdoor unit, which contains the compressor and condenser coil
An indoor unit, which includes the air handler or furnace and the evaporator coil
These two units work together to heat or cool your home by circulating refrigerant between them. Depending on the season, the system either absorbs heat from inside your home and releases it outdoors (for cooling) or draws in heat from outside and transfers it indoors (for heating).
How Does a Split System Work?
A split system uses refrigerant lines, ductwork, and airflow components to manage your home's temperature efficiently.
In cooling mode, the refrigerant absorbs heat from indoor air and moves it to the outdoor unit, where it's released.
In heating mode, if paired with a heat pump, the process reverses — bringing heat into your home.
This setup allows for efficient and consistent comfort throughout the year.
Why Split Systems Are a Popular Choice
Split HVAC systems are ideal for many homeowners because they offer:
Energy efficiency: Properly sized split systems deliver powerful heating and cooling with lower energy use.
Year-round comfort: Combine an air conditioner with a furnace or a heat pump for full seasonal control.
Quiet operation: Indoor components operate with minimal noise compared to window units or packaged systems.
Flexible installation options: Works well in new builds or existing homes needing a system replacement.
If you're considering upgrading your home's HVAC setup, Estes Services can help you find the right Carrier split system for your needs.
