As an HVAC expert, I am often asked about the best practices for maintaining air conditioning units. One question that frequently comes up is how often the outdoor AC unit should be cleaned. The answer is not a simple one, as it depends on various factors such as usage, location, and climate. However, there are some general guidelines that can help homeowners keep their outdoor AC unit in top shape.
First and foremost, it's important to clean the outdoor unit regularly during the cooling season. This means cleaning it at least once a month. This will help prevent dust and debris from building up and affecting the unit's efficiency. Additionally, it's a good idea to include cleaning the outside of the unit as part of your weekly household cleaning routine.
This will help keep the unit free from any surface dirt or grime that may accumulate over time. Another crucial aspect of maintaining your outdoor AC unit is replacing the HVAC filter every 1 to 3 months. This not only helps reduce dust and other irritants in the air, but it also prevents them from clogging the window air conditioning filter. A clogged filter can significantly impact the unit's performance and lead to higher energy bills.
A general rule of thumb is to clean or replace filters once a month during the season of use. However, if you only use your air conditioner occasionally, you may be able to do it every other month. It's always best to err on the side of caution and make it a monthly habit. I recommend setting a reminder on your calendar for the first day of each month to ensure you don't forget.
