Keep a watch over the exterior coil: Make sure to remove debris or accumulation of unwanted elements such as grass, weeds and leaves on the exterior coil from time to time in order to allow your unit to operate smoothly. You can use garden hose to clean it. Watch out the indoor unit: Clean dust with warm water and use any soft piece of cloth to dry the indoor unit. This is important in order to ensure uninterrupted operation of the unit. Replace carbon filters: Change carbon filters at regular intervals to facilitate quality airflow. These filters need to be replaced once in three months. Make a note of runoff: It is important to check if your unit is draining rightly.

Contact any Licensed HVAC contractor for annual servicing: It will be great to hire professional maintenance services for your heating and cooling system. Regular maintenance services ensure the longevity of your unit. In addition, if the unit is well maintained, its energy efficiency and performance will also improve. You can hire these services either by making a call to the contractors as and when need arises or obtaining an annual contract. The last option is desirable as it is cost-effective and guarantees you technical support whenever required. However make sure that the professional checks several points of your unit such as electrical connection, moving mechanical components and refrigerant levels.
