We recommend home and building owners carry out some basic maintenance on your AC unit before the onset of summer and winter to maintain good indoor air quality as well as keep energy usage down. There are maintenance procedures that you can carry out yourself to ensure that your AC is optimized for best performance during the hot and cold seasons.

Monthly or quarterly cleaning and replacement of the air filter(s) are recommended to avoid clogging. A clogged filter will result in poor indoor air quality. Once a filter is clogged and no longer able to capture particulates, the debris will simply pass around these clogged filters and will enter the coils and air stream. A clogged filter will also create more resistance requiring the fan to work hard and will consume additional energy necessary to move the air.

Trash or vegetation built up around exterior units will also affect the unit’s performance; thus, you need to keep the area around free of such. External units make use of fins to dissipate air. Regular cleaning and maintenance of your exterior coils will extend the unit’s life.
