Your AC filters are designed to filter out dust and debris from your indoor air. When you are planning out your air conditioner services for the summer season, it is important to factor in your AC filter replacement schedule. By changing your AC filters on a periodic basis, you can maximize the performance and quality of your system. Your AC filter replacement schedule is determined by the size and model of your filter. For example, a one-inch filter will need to be replaced every six to eight weeks. By contrast, a four-inch furnace will require replacement every three to six months. If you have questions about your AC service schedule, be sure to contact a company offering AC installation near St. George. With the services of a skilled technician that specializes in AC service, you can ensure that your unit is able to provide you with proper cooling throughout the hottest days of the year.
