The exterior of an AC unit is exposed to various elements, such as dirt, dust, and debris, which can accumulate and hinder its performance. Cleaning the outside of an AC unit is crucial to ensure optimal efficiency and extend its lifespan.

Here are some helpful tips for cleaning the outside of an AC unit.

Turn off the power

Before cleaning, turn off the power supply to the AC unit. Also, unplug the unit from the power source.

Remove debris

Start by removing any debris or clutter around the AC unit. Trim any overhanging branches or vegetation blocking the unit's airflow. Sweep away leaves, grass, or dirt from the surrounding area to keep it clean and clear.

Clean the fins

The fins, located on the exterior of the AC unit, are responsible for dissipating heat. They can accumulate dust and debris over time, reducing airflow and efficiency. Use a soft brush or a fin comb to clean the fins, being careful not to bend or damage them. Avoid using excessive pressure or sharp objects that could cause damage.

Rinse with water

Once the fins are brushed clean, use a garden hose to rinse the unit's exterior. Start from the top and work downward, washing away any remaining dirt or grime. Be cautious not to spray water directly into the electrical components or the motor.

Straighten bent fins

Bent or misaligned fins can obstruct airflow, reducing the AC unit's performance. Use a fin comb or a blunt object to carefully straighten any bent fins, ensuring they are all aligned and unobstructed.

Check the condenser coils

The condenser coils can also collect dirt and debris. Inspect the coils for any visible dirt or clogs. If needed, use a coil cleaner or a combination of mild detergent and water to clean them. Use water to rinse thoroughly and allow them to dry completely before reassembling the unit.

Remove pests

AC units can attract pests such as insects, rodents, or birds, which can create nests or cause damage. Check for any signs of pest infestation and take appropriate measures to remove them safely, following local regulations and guidelines.

Regular maintenance

To keep the outside of an AC unit clean and functioning optimally, incorporate a regular HVAC maintenance routine. Aim to clean the outside of the unit at least once a year or as needed, depending on the environmental conditions.

Call an expert for assistance

If you're unsure or uncomfortable with cleaning the AC unit, it's best to seek a competent HVAC specialist to avoid any potential damage or accidents.
