We’ve seen the difference a clean air conditioner can make on those hot summer days. Keeping your AC in good shape is essential for a comfortable journey, and cleaning the coils is a key part of that.
Dirty coils can make your system work harder, reducing efficiency and cooling power.
Let’s go through a step-by-step guide to ensure your air conditioner is running at its best, complete with product recommendations to help you along the way.
Gather Your Supplies
Before you start, make sure you have everything you need. You’ll require a few essential items: a coil cleaner specifically designed for RV air conditioners, a soft brush, a vacuum with a brush attachment, a fin comb, a screwdriver, and safety gloves.
Having the right tools on hand makes the job easier and ensures you don’t damage any components during the cleaning process.
Product Recommendations:
- Coil Cleaner: Nu-Calgon 4291-08 Nu-Brite
- Fin Comb: Rectorseal Fin Comb Tool
Turn Off the Power
Safety first! Before you do anything, make sure the power to your RV’s air conditioner is turned off. You don’t want to risk any electrical accidents.
Turn off the power at the breaker box and unplug your RV from any external power source. This step is crucial to avoid any shocking surprises while you work.
Remove the Cover
Now, it’s time to get to the coils. Use a screwdriver to remove the screws securing the air conditioner’s outer cover. Carefully lift the cover off and set it aside. This will give you access to the coils and other internal components.
It’s a good idea to take a picture of the unit before you start removing parts, so you remember how everything goes back together.
Clean the Evaporator Coils
The evaporator coils are usually located at the front of the unit. These coils can accumulate dust and debris, reducing their efficiency. Use your vacuum with a brush attachment to gently remove loose dirt and debris.
Be careful not to bend the delicate fins.
After vacuuming, spray the coils with a coil cleaner. Let the cleaner sit for a few minutes to break down the grime, then use a soft brush to scrub away any remaining dirt. Rinse the coils with water if the cleaner instructions recommend it, and let them dry completely.
Product Recommendation:
- Soft Brush: OXO Good Grips Scrub Brush
Clean the Condenser Coils
The condenser coils, typically found at the back of the unit, also need attention. Follow the same steps as for the evaporator coils: vacuum the coils to remove loose debris, apply the coil cleaner, let it sit, and then gently scrub with a soft brush.
The condenser coils are crucial for releasing heat from the AC unit, so keeping them clean is essential for optimal performance.
Straighten the Fins
Over time, the fins on your coils can get bent, restricting airflow. Use a fin comb to straighten any bent fins carefully.
This tool is designed to fit between the fins and gently realign them without causing damage. Properly aligned fins improve airflow and help your AC unit run more efficiently.
Inspect the Filter
While you’re at it, check the air filter. A dirty filter can hinder airflow and reduce your AC’s efficiency. If the filter is reusable, clean it according to the manufacturer’s instructions.
If it’s disposable, replace it with a new one. Regularly maintaining the filter keeps your air conditioner running smoothly and your indoor air quality high.
Reassemble the Unit
Once everything is clean and dry, it’s time to put your air conditioner back together. Carefully replace the cover and secure it with the screws you removed earlier.
Double-check that everything is properly aligned and tightened. If you took a picture before disassembly, refer to it to ensure everything is in the right place.
Restore Power and Test
With the cover back on, restore power to your RV’s air conditioner. Turn the breaker back on and plug in your RV. Turn on the air conditioner and let it run for a while.
Check to make sure it’s cooling effectively and that there are no unusual noises or issues. If everything seems to be working fine, you’re all set for a cool and comfortable summer.
Schedule Regular Maintenance
Regular maintenance is key to keeping your air conditioner in top shape. Aim to clean the coils at least once a year, or more often if you use your RV frequently in dusty or pollen-heavy areas.
Regularly cleaning the coils helps maintain efficiency, reduces the risk of breakdowns, and extends the life of your air conditioner.
