First of all, it is recommended that one should keep all kind of debris from the unit’s housing and there should be enough clearance. Leaves, birds, twigs, and various other kinds of trash can clog the free flow of air through the unit which in turn can cause strain on the AC thereby shooting up the electricity bill. Thus, all efforts need to be taken to remove all unwanted growth from the outdoor unit of the air conditioner.
The air filters play a significant role in the functioning of the air conditioner and nothing decreases the efficiency of ACs more than dirty filters. When the air filters are dirty, the air conditioner will have to work hard in order to produce the desired amount of cooling. This makes the unit work harder which uses more energy, shoots up the electricity bill and at the same time, the unit also gets damaged.
Attic ventilation is an important aspect that has an impact on the efficiency of air conditioners. The improvement in attic ventilation can reduce the attic temperature which in turn can make the air conditioners considerably more efficient. However, one ought to keep in mind that placement and proper sizing of the roof ventilation is one of the most effective ways to keep your attic cooler.
You will have to ensure that the ventilation fins are open properly because very often the ventilation fins are closed thus restricting airflow. A fin comb can be used to make the fins open. This will ensure that the airflow to the unit is not restricted and the air conditioner also need not work hard, thus keeping the electricity bills under control.
