Depending on the year, air conditioning can be a lifesaver. However, air conditioning can easily be taken for granted. Whether it’s an external unit powering a central air system or a good old-fashioned window unit, it’s important to keep your air conditioning system in good working condition.
One of the most simple, yet effective, ways to keep your air conditioner working properly is to clean or replace the filter. It can be very easy for the filter to become dirty, which blocks the air from being pulled into the unit, leading to inefficiency or damage. So be sure to regularly remove the filter to vacuum or hose off dirt and debris.
Of course, other maintenance tasks can be done to keep your air conditioner in good condition. Often, though, these require powering down and opening up the unit; for these, it may be a better idea to hire a professional.
