At the core of every central air conditioning system lie two essential components: the evaporator coil and the condenser coil. Understanding their roles and how they work together is key to appreciating their importance and the potential costs associated with their failure.

Evaporator Coils: Absorbing the Heat

The evaporator coil is located inside your home, typically within the air handler or furnace.

Its primary function is to absorb heat from the air that's being circulated throughout your home.

As warm air blows across the cold evaporator coil, the refrigerant inside absorbs the heat, causing the air to cool down.

This cooled air is then distributed through your ductwork, providing the refreshing relief you expect from your AC system.

Condenser Coils: Releasing the Heat

The condenser coil, on the other hand, resides in the outdoor unit of your central AC system.

Its job is to release the heat that was absorbed by the evaporator coil inside your home.

The hot refrigerant travels to the condenser coil, where it dissipates its heat into the outside air, facilitated by a fan.

This process converts the hot refrigerant back into a liquid, ready to begin the cycle again.

The Refrigerant's Crucial Role

Both coils rely on refrigerant, a special substance that circulates within the closed-loop system.

Refrigerant acts as the heat transfer medium, absorbing heat in the evaporator coil and releasing it in the condenser coil.

Without refrigerant, the entire cooling process would grind to a halt. The type of refrigerant used can also influence the cost of repairs and replacements, as we will explore later.

The Importance of Functional Coils

If either the evaporator or condenser coil malfunctions, the entire cooling system's efficiency is compromised.
