It’s easy to forget about your air conditioner’s outdoor unit. After all, the cool air and comfort it provides are felt inside your home. However, maintaining this outdoor unit, also known as the “condenser,” is important for the overall efficiency and longevity of your air conditioning system.
In this blog, we’ll guide you through how to clean your outdoor AC unit to keep it running at its best all year long.
The Important Role of the Outdoor AC Unit
The outdoor unit, commonly known as the condenser unit, houses essential components like the compressor, condenser coils, and condenser fan. These parts work together to release the heat absorbed from your home’s indoor air, allowing the cooled air to circulate back inside. Over time, dust, dirt, leaves, and other debris can accumulate on the condenser coils and fins, impairing the unit’s ability to release heat. This build-up forces the unit to work harder, increasing wear and tear and leading to higher energy consumption.
Gather Your Cleaning Tools
Before diving into the cleaning process, double-check that you have the necessary tools on hand. Here’s a list of items you’ll need:
- Garden hose or water hose
- Coil cleaner (specifically designed for AC units)
- Soft bristle brush
- Shop vac
- Fin comb
- Butter knife
- Screwdriver
- Spray nozzle
- Vacuum
- Protective gloves and eyewear
How to Clean Your Outdoor AC Unit: Step-by-Step
Have you gathered the necessary tools and materials? As you can see, you’ll need many pieces of equipment, including a garden hose, a coil cleaner, a soft bristle brush, and a fin comb. It’s also a good idea to have a screwdriver handy to access some parts of the unit.
Are you ready to begin? Let’s dive into how to clean your outdoor AC unit:
Step 1: Turn Off the Power
Safety first! Locate the electrical disconnect box near the outdoor unit and switch off the power. If you can’t find the disconnect box, turn off the breaker that supplies power to the AC unit. This step is critical to prevent any electrical accidents.
Step 2: Clear the Area Around the Unit
If you want to maintain a clean AC condenser, start at square one. Remove any large leaves, plants, and other debris from around the unit. Clearing at least two feet around the unit helps guarantee proper airflow. Trim back any overgrown vegetation that could obstruct the airflow or drop debris into the unit.
Step 3: Remove the Outer Covers
Using a screwdriver, remove the screws that hold the outer covers or the top grille in place. Carefully lift off the cover, and do not disconnect any electrical components. If your unit has a fan attached to the cover, gently set it aside, ensuring the wires are not strained.
Step 4: Clean the Condenser Fins
The condenser fins are delicate and can easily bend, so use a soft bristle brush or a fin comb to gently clean between the fins. Remove any dust, dirt, and other debris lodged in the fins. For stubborn dirt, you can use a fin comb to straighten and clean the fins.
Step 5: Vacuum the Interior
Using a shop vac, carefully vacuum any debris inside the unit. Be cautious around the electrical components and wiring. This step helps remove any loose dirt and debris that could obstruct airflow.
Step 6: Spray the Condenser Coils
Apply a coil cleaner to the condenser coils, following the manufacturer’s instructions. Let the cleaner sit for the recommended time to loosen any dirt and grime. Then, using a garden hose with a gentle spray nozzle, rinse off the cleaner from the coils. When you clean AC condenser coils, avoid using a power washer, as the high pressure can damage the delicate fins and coils.
Step 7: Clean the Fan Blades
Wipe down the fan blades with a damp cloth to remove any dust and dirt. Check for any damage or wear and tear on the blades, then replace them if necessary.
Step 8: Reassemble the Unit
Once everything is clean and dry, carefully reassemble the unit. Replace the outer covers and secure them with screws. Confirm that all electrical components are connected properly.
Step 9: Restore Power
Switch the power back on at the disconnect box or breaker. Set your thermostat to cool mode and check if the unit is running smoothly. Listen for any unusual noises; loud sounds could signal a problem that needs professional attention.
Common Mistakes to Avoid
When cleaning your outdoor AC unit, avoid these common mistakes:
- Using a Power Washer: The high pressure can damage the delicate fins and components. Stick to a garden hose with a spray nozzle.
- Skipping Safety Measures: Always shut off the power to the unit before starting any cleaning or maintenance tasks.
- Ignoring the Fins: Bent or clogged fins can significantly reduce efficiency. Take the time to clean and straighten them properly.
- Using Harsh Chemicals: Only use coil cleaners specifically designed for AC units. Harsh chemicals can damage the coils and other components.
When to Call a Professional
While regular cleaning can be done by most homeowners, some tasks are best left to professionals. If you notice any of the following issues, it may be time to call an HVAC technician:
- Strange Noises: Unusual sounds coming from the unit can indicate trouble with the fan, compressor, or other components.
- Reduced Cooling: If your AC unit isn’t cooling as effectively as before, it may need a professional inspection.
- Frequent Cycling: If the unit turns on and off frequently, this could suggest there’s an issue with the thermostat, refrigerant levels, or other parts of the system.
- High Energy Bills: A sharp rise in your energy bills can signal a problem with the AC unit’s efficiency.
