Dirt and neglect are the top causes of heating and cooling system inefficiency and failure. To ensure efficient system operation, it’s important to perform routine maintenance.
Change your air filter regularly. A clean filter will prevent dust and dirt from building up in the system, which can lead to expensive maintenance and/or early system failure. Check your filter every month, especially during winter and summer months, when use tends to be heavier. Change your filter if it's dirty— or at least every three months.
Tune up your HVAC equipment. Proper maintenance by a qualified technician is one of the most important steps you can take to prevent future problems. Contractors get busy during summer and winter months, so it is best to check the cooling system in spring and the heating system in the fall. Plan the checkups around the beginning and end of daylight-saving time each spring and fall.
