Clean and Maintain Your AC Equipment
According to Weiner, “keeping your AC and furnace filters clean can improve the system’s efficiency by 5 to 15 percent. Many systems have a filter in the outdoor condenser unit that helps keep the coils clean, maximizing efficiency. For indoor air quality and proper flow, it’s also important to replace furnace filters as needed throughout the cooling season.
Kellogg offers similar advice and adds, “I tell people to forget the standard routine of checking filters every three months and do it once a month. An easy way for them to remember is to check the filters every time they get a utility bill.” Kellogg also recommends shading your outdoor unit and making sure it is level and has at least 1 foot of free air space on all sides.
