Clogged, dirty filters block normal airflow and reduce a system’s efficiency significantly. 正常气流受阻, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil’s heat-absorbing capacity. 更换脏的, clogged filter with a clean one can lower your air conditioner’s energy consumption by 5% to 15%.
For central air conditioners, filters are generally located somewhere along the return duct’s length. Common filter locations are in walls, ceilings, furnaces, or in the air conditioner itself. Room air conditioners have a filter mounted in the grill that faces into the room.
Some types of filters are reusable; others must be replaced. They are available in a variety of types and efficiencies. Clean or replace your air conditioning system’s filter or filters every month or two during the cooling season. Filters may need more frequent attention if the air conditioner is in constant use, 是否处于多尘的环境中, 或者你家里有毛茸茸的宠物.
关键的考虑
Make sure that around outdoor air conditioning units and heat pumps there is at least 2 feet of clearance from plants and storage items.
检查通往房屋的制冷剂管路. 如果绝缘缺失或损坏，请更换.
冷凝器必须保持水平，才能正常工作. 如果不是的话, then problems with drainage and premature wear and tear will occur. The unit must be level in both orientations, (north/south and east/west). 如果不是的话, adjust the height and level the unit by adjusting the leveling feet, or by shimming the feet with wood shims slightly to achieve level. 如果机组严重错位, 然后修理或更换单元所依赖的垫, 和/或调整景观等级.
To lubricate the fan bearings and clean the condenser on the inside, 你必须先关掉机器的电源. Open the disconnect metal electrical box near the unit, then remove the power plug which activates the box or turn off the power with the shutoff handle or remove the fuse plug. Also turn off the power to the unit at the main electrical service panel. Wait a few minutes before proceeding with any further maintenance steps. This will allow any stored electrical charge that may reside with the unit’s capacitor to dissipate.
To access the outside and inside of the condenser coil you must remove the protective side grille. You also need to remove the top panel that protects the fan, 电动机, 以及冷凝装置的内部.
移除格栅, remove the screws holding the side and top panels in place, 用十字头, flat-blade screwdriver or socket driver as required and place the screws in a secure area.
小心, pull the side grille away from the unit and lift the top panel which may also support the fan 电动机. Carefully support the top grille with the 电动机 and fan making sure not to stress the electrical wire connectors.
Locate the fan 电动机 oil ports above the fan blades and place a few drops of lightweight household oil into each port.
Clean dirt, leaves, and other debris from outside the condensing coils. Check the condensing coil fins and fan for damage from wind and hail. Vacuum the outside of the coil fins using a soft bristle brush attachment. 吸尘时不要把翅片弄弯.
一旦外部相对清洁, 用带喷枪的软管清洗内部, spraying water from inside the coil through to the outside of the coils, 哪一种能清除被粘住的碎片. 不要喷风机电机或电线.
Vacuum out or remove by hand any debris littering inside bottom of unit.
If your unit has no bent coil fins, then replace the grille cover. 如果你的单位有弯曲的鳍, they should be straightened out as much as possible for proper performance of the unit. 联系 Oak View Mechanical to have the fins properly combed straight.
To power the unit back on after it has been shut off more than three hours, proceed by switching the thermostat inside your home to the “off” position. Restore power at the outside electrical disconnect box and service panel. Turn the thermostat to “cool” to power the unit back on.
While these maintenance procedures outlined within are manageable by homeowners, we recommend that they be performed by licensed HVAC contractors, who also run diagnostic tests to ensure that the system is operating optimally.
