Maintaining the health of your HVAC system is crucial for good indoor air quality in your home. An unmaintained HVAC system can lead to several problems, including:
- Increased presence of allergens and pollutants.
- Higher energy costs due to inefficient operation.
- Reduced lifespan of the HVAC system.
Part of this routine maintenance is cleaning your AC unit regularly. Below, we list out all the steps you’ll need to take to keep your air conditioning in good shape.
1. Turn off the Power
Before you start cleaning your air conditioner, make sure to turn off the power. This step is crucial for your safety and prevents any accidental electrical shocks. Locate the shut-off box near your unit and switch it off. If you can’t find it, turn off the power at your home’s main circuit breaker.
It’s important to ensure that the unit is completely powered down before proceeding. Check by attempting to turn it on after you’ve switched off the power. Double-checking ensures that there is no residual power running through the unit.
2. Clear Debris
The next step involves clearing any debris from around your outdoor AC unit. Over time, leaves, twigs, and dirt can accumulate around the unit, obstructing airflow and reducing its efficiency. Use a garden rake to clear away larger debris, and then follow up with a broom to sweep away smaller particles.
Pay attention to the base of the unit, as this area tends to collect the most debris. Regularly clearing this area reduces strain on the unit and allows it to operate more efficiently.
After clearing the debris, hose down the area around the unit to remove any remaining dust or dirt. This step helps ensure that the surrounding area is clean and free from obstructions that could affect the unit’s performance.
3. Remove and Clean the Fan Cage
To access the interior of your AC unit, you’ll need to remove the fan cage. Use a screwdriver or wrench to remove the screws or bolts securing the cage to the top of the unit. Carefully lift the cage off and set it aside.
Once the fan cage is removed, clean it thoroughly. Use a brush or vacuum to remove any dust and debris that has collected on the blades. Cleaning the fan cage ensures better airflow and improves the unit’s overall efficiency.
4. Clean the Fins
The fins of your AC unit play a crucial role in heat exchange, so keeping them clean is essential. Use a soft brush or vacuum with a brush attachment to gently clean the fins. Be cautious not to bend or damage them during the cleaning process.
Ensure that the fins are completely dry before proceeding to the next step. Properly cleaned fins improve the unit’s efficiency and help maintain optimal indoor air quality.
5. Straighten Bent Fins
Bent fins can obstruct airflow and reduce the efficiency of your AC unit. Use a fin comb, which is specifically designed for this purpose, to straighten any bent fins. Gently run the comb through the fins, aligning them properly.
If you don’t have a fin comb, you can use a butter knife or similar tool, but exercise caution to avoid causing further damage. Straightening the fins allows for better airflow and enhances the unit’s cooling capacity.
6. Clean the Area Around the Unit
A clean environment around your AC unit contributes to its efficiency. Trim any bushes or plants that are within two feet of your outdoor unit. This clearance ensures adequate airflow and prevents debris from accumulating around the unit.
Additionally, check for any structures or objects that might obstruct airflow and relocate them if necessary. Maintaining a clear space around the unit allows for better heat exchange and reduces the risk of overheating.
7. Clean the Evaporator Coil
The evaporator coil inside your AC unit can accumulate dirt and dust over time, reducing its efficiency. To clean the coil, locate it inside the unit, usually near the air handler or furnace. If you’re unsure, consult your unit’s user manual for guidance.
Use a soft brush to gently remove any dust and debris from the coil. For a deeper clean, consider using a no-rinse coil cleaner spray. Apply the spray evenly across the coil and allow it to sit for a few minutes before turning the unit back on.
8. Change the Air Filter
One of the simplest yet most effective steps in maintaining your AC unit is regularly changing the air filters. A dirty air filter restricts airflow and reduces the unit’s efficiency. It can also lead to poor indoor air quality by circulating dust and allergens.
Check your unit’s user manual to locate the air filter compartment. Remove the old filter and replace it with a new one of the same size and type. Generally, it’s recommended to change the filter every 1-3 months, depending on usage and air quality.
9. Check the Thermostat
A properly functioning thermostat is essential for maintaining a comfortable indoor temperature. Check your thermostat to ensure it’s set to the desired temperature and functioning correctly. If you have an older thermostat, consider upgrading to a programmable or smart thermostat for better control and energy efficiency.
Follow the manufacturer’s instructions to calibrate the thermostat if necessary. Proper calibration ensures accurate temperature readings and efficient operation of your AC unit.
10. Schedule Professional Maintenance
While regular DIY maintenance is essential, it’s also crucial to schedule professional maintenance for your air conditioning unit. HVAC professionals have the expertise and tools to perform thorough inspections and address any potential issues before they become major problems.
Consider scheduling a professional maintenance check at least once a year, preferably before the cooling season begins.
