Maintaining Window A/C Units

One of the benefits of using wall air-conditioning units is that the machines merely require the user to plug them in, adjust the settings to the desired level of comfort – and nothing more.

If only that were the case. Window A/C units, like practically any other appliance, require regular maintenance. The good news is that taking the short amount of time to perform that maintenance on a regular basis should save you money in the long run, especially during those heat waves when A/C units are running around the clock.

The first task is to check the filter – and not just at the start of the season. Regularly inspecting the filter, even when summer is in full swing, will help to ensure that your air conditioner is operating at maximum efficiency. And remember: Dust and dirt that collects at the back or underside of a filter can impede airflow without necessarily being seen as doing so. A good washing of the filter on a regular basis will keep the cool air pumping all summer long.

Next, take a look at the unit’s output vents to be sure that nothing is obstructing the airflow. Cleaning the filter does no good if dirt and debris have collected in the vents.

Be sure to take a good look at the condition of your electrical cord – while the unit is unplugged. This way, you can handle the cord and inspect it closely for any wear or possible fraying, without running the risk of accidentally discovering a problem while the power is on! A damaged cord can be more than a mere inconvenience; it can allow heat and resistance to build up, resulting in greater possibility of a fire.

Finally, inspect all of the unit’s controls to ensure that all are in good working order. This includes double-checking that the controls actually do what they are supposed to do. Knobs, sliders and switches should be cleaned (including the areas underneath), so that dirt, grease or dust do not cause an obstruction – such as stopping a control prematurely, which could result in a unit that appears to only partially cool, when dirt, not the control or the unit, is to blame.
