What Kind of Air Filter Should I Use?
Al from A & A Cooling & Heating LLC in Apache Junction, Arizona recommends using an inexpensive air filter and checking and replacing the filter for proper airflow. Other types of air filters such as washable filters, allergen sensitive filters, etc actually “restrict” airflow due to dirt build-up and can be damaging to your unit. Utilizing an inexpensive air filter but checking it every 2 weeks and changing it monthly is the key to the lifespan and efficiency of your AC unit.
