From your toothbrush to your car tires, and everything in between, find out when to replace the things you own.
HVAC (heating, ventilation and air conditioning) filters should be replaced once a month during high-use seasons like summer and winnter, and once every three months during low-use seasons like spring and fall. You can easily tell if they're ready to be replaced when they look dirty. Dirty air filters can cost you $200 - $300 more a year in energy costs since the unit has to work harder than it would with a clean filter.
