Moreover, a dirty AC system can also lead to poor indoor air quality, which can negatively affect your health and comfort. Airborne contaminants like bacteria, mold, and dust may circulate throughout your home and cause or worsen allergies, asthma, and other respiratory problems.
To avoid these issues and ensure your AC unit’s maximum performance and longevity, it’s crucial to clean the coils outside regularly. This guide will provide you with easy-to-follow instructions on how to do it safely and effectively, along with some helpful tips on maintaining your AC system and common mistakes to avoid.
2. Understanding the Components of an AC System and the Role of Coils
Before we dive into the details of how to clean AC coils outside, it’s important to understand the components of an AC system and the role of coils in its functioning.
The Components of an AC System
An AC system comprises several components that work together to cool your home or office space. The main components include:
- The compressor
- The condenser
- The evaporator
- The expansion valve
- The refrigerant
The Role of Coils in an AC System
Coils are an integral part of the AC system and play a crucial role in the cooling process. There are two types of coils in an AC system – the evaporator coils and the condenser coils.
Evaporator coils are located inside the air handler unit or the indoor unit and absorb the heat from the indoor air. The refrigerant inside the coils evaporates and cools the indoor air, which is then circulated back into the room.
Condenser coils, on the other hand, are located in the outdoor unit and function by releasing the absorbed heat from the evaporator coils into the outdoor air. The refrigerant inside the coils condenses as it releases the heat, and the process repeats.
In summary, the coils in an AC system facilitate the movement of refrigerant between the indoor and outdoor units, which is responsible for cooling your home or office space. Without clean coils, the AC system would become inefficient and struggle to perform its role effectively.

Follow these step-by-step instructions to safely and effectively clean your AC coils.
Step 1: Turn off the power to your AC unit. You can do this by switching off the circuit breaker or unplugging it.
Step 2: Remove any debris or dirt from the exterior of the AC unit with a hose or brush. Be careful not to damage the fins of the AC coils when using a brush.
Step 3: Remove the fan from the top of the AC unit. Use a screwdriver to detach the screws and carefully lift the fan away from the unit. Be careful not to damage any wiring connected to the fan.
Step 4: Use a coil cleaner to spray the coils from the inside out. Be sure to follow the manufacturer’s instructions for the specific coil cleaner you are using.
Step 5: Let the coil cleaner sit for 10-15 minutes to allow it to penetrate the dirt and debris on the coils.
Step 6: Rinse the AC coils with a hose, starting from the inside and working your way out. Be careful not to use too much pressure as this can damage the coils.
Step 7: Reattach the fan and screws and turn the power back on.
Regular cleaning of your AC coils outside is essential to maintain the efficiency of your AC system and prolong its lifespan. By following these step-by-step instructions, you can safely and effectively clean your AC coils and keep your HVAC system running smoothly.
4. Best Practices for Maintaining Your AC System and Extending Its Lifespan
Regular maintenance is the key to extending the lifespan of your AC system and optimizing its performance. Here are some best practices that you should follow to keep your system in top shape.
Replace Air Filters Regularly
Air filters play a critical role in protecting your AC system from dust, dirt, and other airborne particles that could damage the coils and reduce the efficiency of the system. Over time, the filters become clogged and less effective at trapping particles, which makes it harder for the system to circulate air properly. To avoid this problem, replace your air filters every 3-6 months, or more frequently if you have pets, allergies, or live in a dusty area.
Keep the Coils Clean
As we discussed earlier, dirty coils can reduce the efficiency of your AC system and lead to higher energy bills, more frequent breakdowns, and shorter lifespan. To prevent this, clean your coils at least once a year, and more frequently if you live in a dusty or humid climate. Follow the steps outlined in the previous section to safely clean your AC coils outside.
