The reason your air con system has a filter is both to protect the mechanics inside, as well as keeping the air clean inside your home or office. If this filter isn't kept clean you're making your air con system work harder and less efficiently, meaning your energy bill will be higher and your yearly air conditioning service may not be sufficient to keep your unit in good health. Some air con filters have to be cleaned rather than replaced and vice versa. An electrostatic filter is cleaned, while a disposable fibreglass or paper filter should be replaced fairly regularly; anywhere between once a month and twice a year, depending on the air quality in your area. Check it regularly to determine how often you should be changing yours. A filter which needs changing will look clogged with dust.

Air Conditioning Service

Hello,

If the floor or area near the furnace is a dust-bunny breeding area, vacuum or sweep prior to replacing the filter. Locate the service panel, usually on the furnace's lower front or side. Turn off the furnace, then gently pop open or pull down the panel door with your hands; tools usually aren't needed.

Thanks,
