Replace The Air Filter(s)
A clean filter saves you money by helping ensure top system efficiency. Studies have shown that dirty air filters in your heating and cooling system greatly reduce the efficiency of your system, wasting money and energy. They can also reduce comfort by restricting air circulation, and can shorten the life of your equipment.
When replacing your filter(s), always use the same size and type that was originally supplied or consult with your service technician for recommendations. Be sure and replace it with the arrows pointing in the direction of the airflow.
When disposable filters are used, they MUST be replaced every month with the same size as originally supplied. Optionally, you may clean or replace your filter(s) twice a month during seasons that require the system to operate more often.
When washable filters are used, they MUST be washed every month. Dirt can be removed by washing the filter outside with a garden hose. A water spray will typically be all that is required to remove the dirt. If deeper cleaning is required, a gentle cleaning solution may be applied to the filter before clear rinsing with water.
Ask the technician where the filter is located in your system and how to service it.
Maintain Free Outdoor Coil Airflow
Efficient operation of your system depends on the free flow of air over the outdoor unit’s coil.
Do not plant flowers or shrubbery right next to the unit. Additionally, make sure that nothing is stacked against the sides of the unit or draped over it.
Buildup of snow or ice can restrict air flow. As soon as possible after accumulation, clean snow or ice from area around the outdoor unit.
Clean The Finish
To keep your system looking new for years, clean the exterior finish with soap and water. For stubborn grease spots, use household detergents. Do not use lacquer thinner or other synthetic solvents as they may damage the finish.
