Do I Really Have to Change My Air Filter Often?
Yes. Changing your air filter at least once every six months will not only help you save on your monthly bills but also will help extend the life of your system.
All of the air in your home circulates and re-circulates through the same filter attached to your indoor unit. Designed to remove dust particles to keep the air you breath clean, filters become clogged, causing your system to work less efficiently and costing you more to operate it. If left unchanged long enough, your system could fail completely.
