Keeping your AC coils clean is essential for maintaining the overall efficiency and longevity of your air conditioner. The coils in your AC, specifically the evaporator, and condenser coils, play a vital role in heat exchange. The evaporator coils absorb heat from your indoor air, while the condenser coils release it outside. Over time, these coils accumulate dust, dirt, and grime, which hinders their ability to function properly.
When the coils are dirty, your
AC has to work harder to cool your space. This increased effort leads to higher energy consumption and, consequently, higher utility bills. A dirty evaporator coil struggles to absorb heat, and a clogged condenser coil cannot efficiently release it, making the system work overtime. Regular cleaning of your AC coils helps ensure proper airflow, efficient operation, better air quality, and a longer lifespan for your air conditioner, saving you money in the long run.
Step by step cleaning process for AC coils
- Turn off the power: Before starting, ensure that the AC is switched off and unplugged to avoid electrical accidents.
- Remove the AC cover: If your AC has a removable cover, take it off to access the coils.
- Gather tools and materials:
- Coil cleaner (available at hardware stores or online)
- Soft brush (such as a paintbrush or toothbrush)
- Fin comb (for straightening bent fins)
- Garden hose or spray bottle
- Gloves and safety glasses
- Clean the evaporator coil:
- Use the soft brush to gently remove dirt and dust from the surface of the evaporator coil.
- Spray the coil cleaner directly onto the coil and let it sit for the recommended time to break down any debris.
- After the cleaner has set, gently rinse the coil with a hose or spray bottle.
- Clean the condenser coil:
- Use the same process to clean the condenser coils, which are located on the outside unit.
- Make sure to remove any large debris like leaves or dirt from the area first.
- Straighten any bent fins with a fin comb.
- Check for leaks and issues: Inspect for any leaks, damage, or signs of wear while cleaning.
- Reassemble the unit: Once the coils are clean and dry, reassemble the AC and ensure that everything is securely back in place.
- Regular maintenance: Clean the AC coils every 6 months to maintain optimum efficiency.

Maintenance tips for clean AC coils and efficient operation
- Regular cleaning: Clean the AC coils every 6 months to remove dust, dirt, and grime. This helps in maintaining smooth airflow and cooling efficiency.
- Inspect filters regularly: Check and clean the air filters every month to avoid clogging and ensure optimal airflow.
- Check for leaks: Inspect the system for any refrigerant leaks that can affect performance.
- Use a coil cleaner: Always use an appropriate coil cleaner to avoid damage and ensure thorough cleaning.
- Check refrigerant levels: Ensure that the refrigerant levels are sufficient to maintain cooling efficiency.
- Schedule professional maintenance: Have a professional check-up once a year to inspect the coils, refrigerant levels, and overall performance.
- Protect the outdoor unit: Keep the area around the outdoor unit clean and free of obstructions, such as leaves or debris, for better airflow.
- Monitor system performance: If you notice reduced cooling, longer running times, or increased energy consumption, schedule a service immediately.

Signs your coils need cleaning
- Reduced cooling efficiency: If your AC takes longer to cool the room or struggles to maintain a consistent temperature, it may be a sign that the coils are dirty and obstructing proper heat exchange.
- Increased energy bills: A noticeable spike in your electricity bills could indicate that your AC is working harder than usual due to dirty coils, causing it to consume more energy.
- Frozen evaporator coils: If you notice ice buildup on the evaporator coils, it could mean they are clogged with dirt, impairing airflow and causing the coils to freeze over.
- Warm air from vents: If your AC blows warm or hot air instead of cool air, it suggests that the condenser coil is unable to release heat properly due to dirt and debris buildup.
- Unusual noises: Hissing, rattling, or buzzing noises coming from the unit could indicate that the coils are dirty or obstructed, affecting normal operation.
- Foul odours: If you notice a musty or mouldy smell coming from the AC, it might be due to mould or mildew growth on the dirty coils, especially the evaporator coil.
