How Central Air Works And The Importance Of Keeping The Filter Clean

Blog

You've more than likely heard that it's crucial for you to make sure you keep the filter for your central air conditioning system clean. However, many people still continue to ignore this advice, causing them higher energy bills and possibly even problems with their cooling system. To understand the importance of your air conditioners filter, you first need to understand how your air conditioner works. This will help you understand why it's so important. This article will explain your cooling system to you so you understand what the filter's role is.

The components of your system

Your central air conditioning system will have an air handler, which is generally locate d on the roof or on the side of the house. The air handler is what draws air in, cools it off and sends it back into the house.

The system also includes air ducts which run through the house into the separate rooms. At the end of each duct is a register, and this is the part that comes out of the ceiling or wall that you can adjust to control how the cool air comes in the room.

There is also the thermostat, which regulates the temperature and allows you to change the temperature settings. The thermostat is also where you will turn the system on and off.

The filter is a removable filter that's generally located in the ceiling of a hallway near the center area of your home. The filter is protected and kept in place by a slotted covering that allows air to come inside when the air handler calls for it.

How the system works

When the temperature in your home goes above the setting on the thermostat, it sends a message to the air handler which in turn will cause air from the room to be pulled through the filter and ducts to the handler itself, where the air will be moved through coils and the compressor where it will be cooled due to refrigerant in the system.

The cool air will then make its way back through the ducts where it will exit the system through the registers in each room.

Once the thermometer in the thermostat recognizes that the air in the room matches the temperature request on the thermostat, the system will temporarily shut off.

Cleaning your filter

When the air is pulled through the filter, any dust and hair in the air will come with it. The filter will catch this debris so it doesn't make its way through the system. When the filter is dirty, the air won't be able to pass through the filter as it should and this causes the system to need to work harder. This will raise your energy bills and put more wear and tear on your system.

Along with keeping your filter clean, you should also have an HVAC tech like Enright and Sons come out before the start of the warm season to make sure everything is working properly. This way, they can catch any small problems before they become large, expensive repairs.
