Understanding Evaporator Coils

Delve into the world of evaporator coils, vital components cloistered within the air handler that is crucial for an efficient HVAC system. Discover how these unsung heroes can accumulate grime and why keeping them pristine is pivotal for your comfort and health.

What are evaporator coils?

Evaporator coils sit at the heart of your air conditioning system. They are usually made up of copper tubes that weave through a series of aluminium fins, forming a component inside the air handler or furnace where heat transfer occurs.

As warm air from your home blows over these cold coils filled with refrigerant, the heat is absorbed and cool air is pushed back into your house.

This crucial mechanism doesn’t just chill your indoor environment; it helps dehumidify the air as well. Over time, dust and grime can settle on these coils, inhibiting their ability to absorb heat effectively.

Keeping them clean ensures that your AC runs efficiently, reducing energy consumption while maintaining comfort in your living spaces.

How do they get dirty?

As your air conditioner works to cool your home, air from inside the room passes over the evaporator coils. This air often carries various particles with it, including dust, dirt, and pollen.

These particles can stick to the moist surface of the evaporator coils. Over time, this grime builds up and forms a layer of dirt that can obstruct airflow and impair heat exchange.

Moisture also plays a part in making these coils dirty. The cooling process causes condensation on the coils—like water droplets on a cold glass on a hot day—and this damp environment becomes a magnet for more debris and microorganisms.

Without regular cleaning, this combination of moisture and contaminants not only affects efficiency but could also turn into mould or mildew, which further degrades your system’s performance and potentially impacts indoor air quality.
