Understanding How Your AC Functions

Published on: May 2, 2012

Your air conditioning system is made up of four main systems. Maintaining these systems will help you save money on your energy bills. It is important to understand how the system functions, so you can help keep it running at peak efficiency. Maintaining the system will save you money on your energy bills.

Beginning in the attic, your ducting system delivers all the air that is heated or cooled by your air conditioning system. If there is a leak, moist air will accumulate in the attic, causing rot and mold growth. Your HVAC system has to work harder to compensate. This creates higher energy bills. Once a year, have the ducting system cleaned and inspected. This will ensure you and your family receive the highest quality air your air conditioning system can provide.

The outside condenser houses the coils, pump and the coolant. In the coils, the heat is removed from the air and cooled. The heat is exhausted to the outside. The cooled air is sent to the inside blower unit. Remove bushes, branches and other debris from around the unit. Clear any plant debris from the drain pan. Any worn belts or bearings should be replaced immediately. Bent aluminum fins can be straightened with a special comb.

The thermostat is a major component of your air conditioning system. It regulates the temperature of the air, cycling the system on and off. A digital thermostat is the most accurate device you can install for energy savings. Once a year, change the battery for the thermometer and digital display.

The inside blower unit does more than blow heated or cooled air into the ducts. It takes inside air in through a filter helping to clean the air and keeping the unit free of debris. Cleaning or replacing the filter on a regular basis will help your system run smoothly. The unit also dehumidifies the air for your comfort and prevents mold growth. Excess moisture is then drained to the outside. Pour a cup of household bleach into the drain every month to kill or prevent algae growth.

By understanding and maintaining your air conditioning system, your energy bills will be lower and you will be comfortable in your home.
