One of the affordable steps to improve the operation of the system is to keep the filters clean. Many have an average life-time of three months, but, they should be examined monthly, especially throughout the summer months. The harder the system works, the more likely the filter will become dirty. This makes all the parts of the system work harder to cool the home and can raise energy costs.
To check filters, hold them up to a light. If the light is no longer able to pass through the filter, it is time for a replacement. Choose a pleated filter for much better air quality and filter efficiency.
The area around the outdoor unit should also be kept clean and clear. As a safety precaution, make sure to turn the thermostat off and the circuit breaker to the on position. Ensure anything blocking the units top or sides are removed. Look all around the unit, and remove plant growth, debris and grass clippings caught in the walls of the coils For Information . Cottonwood pollen can create air blocking clogs.
If necessary, use a soft bristle brush to delicately sweep debris from the fins. Fins bend easily, so brush in line with them and be gentle. Be sure any dust or dirt are removed from the fins. This step reduces the resistance for air to go through the coils and improves system efficiency.
Landscaping growing near or touching the unit should be cut. Avoid using a weed eater as it is possible to cut electric cords and damage fins. Hand clippers or garden shears are a better choice, but make sure to look out for electrical hookups.
Inspect the condensate drain. This drain allows the water that condenses in the unit from the moisture in the air to drain outside the home or into a floor drain. The primary cause of clogs is microscopic slime growing in the water. If water is not draining from the unit to the floor drain or outside the home when the unit is running, there is probably an obstruction. If water is collecting around the base of the air handler, there is a guaranteed obstruction. It is best to switch off the unit immediately to avoid even more water damage. Call a certified specialist to do the repair.
Each year the system should be checked and cleaned by a certified specialist. The specialist will certainly ensure the coolant levels are balanced. Operating a system that is low on coolant increases wear and tear in addition to increased energy expenses. Preventative maintenance is the very best way to ensure the home remains cool and the cooling system works efficiently all summer long.
