Have you checked your air filter lately? Make sure to check your filter every month, especially during heavy use in summer. If the filter looks dirty, change it. At a minimum, change the filter every 2 months. A dirty filter will slow down air flow and make the system work harder to keep you cool — wasting energy. A clean filter will also prevent dust and dirt from building up in the system — leading to expensive maintenance and/or early system failure.
