How to Clean AC Coils

As the scorching summer heat approaches, our trusty air conditioners become our best friends, providing much-needed respite from the sweltering temperatures. However, over time, air conditioning coils can accumulate dust, dirt, and debris, which can hinder their efficiency and even lead to costly repairs. To keep your AC unit functioning optimally, regular maintenance is crucial. In this blog post, brought to you by My Buddy the Plumber, we will guide you through the process of cleaning AC coils, ensuring your cooling system remains reliable and energy-efficient throughout the summer.

Why Clean AC Coils?

Air conditioning coils play a vital role in the cooling process. The evaporator coils are responsible for absorbing heat from indoor air, while the condenser coils release the heat outside. When these coils become caked with grime, their ability to transfer heat efficiently diminishes, resulting in reduced cooling capacity and increased energy consumption. Regular cleaning of AC coils can prevent breakdowns, extend the lifespan of the unit, and keep electricity bills in check.

Safety First

Before we dive into the cleaning process, remember that safety should always be your top priority. Make sure to turn off the power supply to the air conditioning unit to avoid any electrical mishaps. Additionally, wear gloves and protective eyewear to shield yourself from any sharp edges or cleaning agents.

Cleaning the Outdoor Condenser Coils

Remove Debris: Start by inspecting the outdoor condenser unit. Clear away any leaves, branches, or debris that may have accumulated around the unit. This step ensures better airflow to the coils.

Spray Down the Coils: Use a gentle stream of water from a hose to wash down the coils. Be cautious not to use a high-pressure setting, as it might bend the delicate fins. Direct the water from the inside of the unit outwards to avoid pushing the dirt further into the coils.

Use a Cleaning Solution: For more stubborn dirt and grime, create a mixture of equal parts water and mild detergent. Gently apply this solution to the coils, allowing it to loosen the debris. After a few minutes, rinse off the solution with water.

Cleaning the Indoor Evaporator Coils

Access the Coils: Open the access panel on the indoor air handler to locate the evaporator coils. Some systems might require removing screws, while others have simple latches.

Brush Off Dust: Using a soft-bristled brush, carefully remove the dust and dirt from the coils. Work in the direction of the fins and be gentle to avoid bending them.

Apply Coil Cleaner: Apply a no-rinse evaporator coil cleaner following the manufacturer’s instructions. This type of cleaner is designed to dissolve dirt without requiring rinsing.

Conclusion: Cleaning AC Coils

Regular maintenance and cleaning of AC coils are essential to ensure your air conditioning system performs optimally, providing you with a comfortable and cool living space. My Buddy the Plumber recommends cleaning your AC coils at least once a year, preferably before the summer season starts. However, if you’re uncomfortable performing this task yourself, don’t hesitate to reach out to a professional HVAC technician who can handle the job efficiently and effectively. Remember, a well-maintained AC system not only keeps you cool but also saves you money in the long run.
