How To Clean a Wall AC

Regular cleaning and maintenance of your wall-mounted air conditioning unit can help keep it running efficiently and effectively. Scheduling periodic cleaning can help prevent dirt and debris build-up which can cause the unit to work harder, use more energy, and ultimately lead to costly repairs. Here are a few tips for maintaining your wall AC:

Create a cleaning schedule

Start by creating a cleaning schedule that works for you. Depending on the usage and the environment of your wall AC’s location, you may need to clean it more often. For instance, if the unit is in a dusty or high traffic area, you may need to clean it once a month.

Clean or replace the filter

The filter is the primary defense against dirt, dust, and other airborne contaminants that can accumulate inside the unit. Clean the filter regularly or replace it at least every two to three months, depending on use and the quality of the filter. Blocked or dirty filters not only reduce the airflow, but can also impact the efficiency of the unit.

Hire a Professional

7. Troubleshooting tips for common wall AC issues

Even with regular cleaning and maintenance, your wall AC may still develop issues over time. Here are some common problems that you may encounter and what you can do to troubleshoot them.

Leaking water

If you notice water pooling around your wall AC unit, it may indicate a clogged drain line. Start by turning off the unit and unplugging it from the power source. Locate the drain line at the base of the unit and use a wet/dry vacuum to suck out any debris or dirt that may be causing the blockage. Once the line is clear, pour a mixture of equal parts vinegar and water through the line and let it sit for a few minutes before flushing it out with water.

Strange noises

If your wall AC is making unusual noises, it may be a sign of a loose or worn-out part. Turn off the unit and check the fan blades and motor for any visible damage or signs of wear and tear. If everything looks okay, try tightening any loose components that may be causing the noise. If the problem persists, it may be best to call a professional for assistance.

Weak airflow

If your wall AC is not blowing enough cool air, it may be due to a clogged filter or evaporator coil. Remove the filter and clean it thoroughly before reinstalling it. If the filter is still in good condition, check the evaporator coil for any dirt or debris and clean it with a soft brush or cloth. If neither of these solutions works, it may be a sign of a more serious issue, and you may need to call a professional for help.

Remember, regular cleaning and maintenance can go a long way in preventing and troubleshooting common wall AC issues. Keep your unit running smoothly by following the tips outlined in this article.
