Maintenance for your A/C system is critical to ensure your system continues to operate properly. One way to help your system during hard running times is to clean or replace dirty filters. You should clean or replace your HVAC system filter once a month during the cooling season. Vacuum off debris, then wash the filter in warm, soapy water; be sure filters are dry before you reinstall them. Replace a filter if it's damaged.
