Step-by-Step AC Coil Cleaning Guide for Better Cooling

HVAC Maintenance

Dust on AC coils may cause your air conditioner to lose as much as 30% of its efficiency. This will result in a spike on your electricity bill, poor cooling, and system damage in the long run. Regular cleaning of AC coils enables efficient performance.

This guide by Clean Now describes the easy steps to cleaning AC coils you can perform at home.

Tools & Materials You’ll Need

Before you start, keep these tools ready:

• Coil cleaner (foam or no-rinse type)

• Soft brush or cloth

• Fin comb

• Vacuum with brush attachment

• Garden hose (low pressure only)

• Spray bottle

• Gloves and safety goggles

• Screwdriver

Step-by-Step Guide to Clean AC Coils

• Turn off AC power to the unit at the breaker for safety

• Open the access panel to reach the coils

• Brush off or vacuum the dust away

• Spray an even coating of coil cleaner onto the coils

• Let the cleaner sit and break down dirt

• Close the panel and turn the power back on

Cleaning Condenser Coils (Outdoor Unit)

• Kill the power at the outdoor unit

• Unclip the top cover or remove a side panel

• Remove leaves, dirt and debris from around the unit

Why Cleaning AC Coils Is Important

Over time, the AC coils will build up dirt, dust, and pollen on them. This will impede heat transfer and put extra wear and tear on your AC system. As a result, you may face

• Increased electricity bills

• Poor cooling performance

• Frequent breakdowns

• Reduced AC lifespan

Regular cleaning improves efficiency and keeps your home comfortable.

Types of AC Coils

Evaporator Coils

It is located inside your home, and draws heat from the room. Clean evaporator coils allow good airflow and effective cooling.

Condenser Coils

These are located outside and release heat into the air. Since they are exposed to dust and weather, they need regular cleaning to work efficiently.

Signs Your AC Coils Need Cleaning

You may need to clean your coils if you notice:

• Weak airflow from vents

• Warm or less cool air

• Higher energy bills

• AC running longer than usual

• Visible dirt on coils

How Often Should You Clean AC Coils?

For most homes, it is enough to have your home cleaned once a year, but if you are home often in a very dusty environment, every 3-6 months would likely yield the most efficient results.
