Spring cleaning isn’t necessarily limited to housecleaning and tidying up closets. Components of your HVAC system can also benefit from some simple upkeep that may not get much attention during the major heating and cooling seasons. Circulating conditioned air accumulates dust and other contaminants that may affect system efficiency, operating costs, and reliability. Here are some suggested tasks that are appropriate for spring cleaning HVAC components.

• Change the system air filter. Particulates and pollutants accumulated during the heating season may obstruct the air filter, compromising airflow and household air quality. Most home HVAC systems benefit from a pleated cotton or polyester filter with a MERV (Minimum Efficiency Reporting Value) ranging between 8 and 12. When replacing the filter, also vacuum out any dust accumulation around the filter frame.  If you receive regular maintenance tune ups, your HVAC professional will change the filter for you.
• Clean the air vents. HVAC supply vents deliver heated or cooled air to each room, while return vents take air back to the central air handler. Dust and dirt accumulation on air-vent grills in rooms can impair air circulation and system efficiency. Remove the grilles and wash them in a sink or outdoors. Also, vacuum any dust accumulation within reach in the interior of the duct.
• Clear the outdoor AC unit. The outdoor condenser coil of a central air conditioner, typically located behind or beside the house, can also benefit from spring cleaning. Cut away weeds, bushes, or other vegetation to establish 3 feet of open space on all sides of the unit for optimum air circulation. Also remove fallen leaves, branches, or any other debris that may obstruct the fan grille on top.
• Check the condensate drip pan. Located beneath the AC evaporator coil in the indoor air handler, the drip pan collects condensation from the evaporator and channels it into the drain system. Check the drip pan for standing water, which indicates sluggish or clogged drainage, as well as the presence of mold growth and/or algae in the pan. If you note any of these symptoms, contact your HVAC contractor for professional service.
