Dirty Ac Filter

Dirty Filters will cause your equipment to work harder than it should. This results in energy waste and even possible internal damage to your air conditioning unit. Become familiar with the type of filter your system requires. If you have a washable, that is reusable, make sure it is completely dry before replacing.

All of the return registers/ grilles should be kept free of obstructions such as furniture, dirt and debris. This will hinder proper air flow.
 
Improving indoor air quality starts with cleaning your humidifier reservoir regularly. Cleanliness of your humidifier will prevent build up of mold and mildew.

Unrestricted air flow to the outdoor unit is extremely important. Remove trash leaves, grass and tree trimmings that are in close proximity. Any debris that collects around the air conditioner will cause your unit to work harder than intended, resulting in using more energy and higher utility bills. The outdoor coil on a heat pump or air conditioner can become obstructed by dust, leaves and yard trimmings. You can use a garden hose and apply gentle, water pressure over the coil, to remove any blockages. Gentle! The blades are fairly fragile on the coil and can be easily bent. Be sure and run water in a downward motion.
