Changing your air filter is one of the easiest ways to keep your air conditioning unit running in tip-top shape. You need to regularly change all the air conditioning filters in your home.
A dirty air filter obstructs your air conditioner’s normal airflow. This makes your system less efficient which increases your cooling costs. In fact, replacing your dirty filter with a clean one can improve energy efficiency.
Plus, a dirty filter can carry dirt into your air conditioner’s evaporator coil. This will prevent your AC from properly sensing temperatures so it can adjust and keep your home cool.
So, how often should I change my air conditioner filter? It depends on the quality of your filter. Cheaper fiberglass filters should be replaced every month. Some higher-end filters can last up to 6 months.
You may need to change your AC more often in the summer months. Check on your air filters every couple of weeks. If it starts to look dirty or clogged, it is time for a new filter.
