In order to maintain its good working condition and operate properly, air conditioners should be maintained regularly. Air conditioners lose around 5% of its efficiency and effectiveness for each year that it operates without maintenance. With the help of a few maintenance procedures that are easy to do, air conditioner units can be able to operate both dependably and economically for many years. Below is a guide on how to maintain your central air conditioning system unit. 

Air Conditioner Unit 

Central Air Conditioning Systems 

The central air conditioner has two components that should be maintained regularly. The first one is the condenser. This component is located outside of your home and it is usually put on a small concrete pad. Next is the evaporator coil. Mounted on its main duct, this component is directly over the furnace. Since central air conditioning units are tied into its airflow system, this unit shares a motor, duct system, as well as the blower used for heating in order to distribute cool air in the entire house. If the air conditioning unit is working but cannot cool the house, then the problem is often traced back to its airflow system. It’s also very important to note that when you work on the air conditioning unit, its power source should always be turned off. 

Maintaining the Central Air Conditioner’s Evaporator 

The evaporator is located in the main air duct above the furnace. If the main air duct junction has an insulation made of foil at the front, then the evaporator can be accessed. This component must be cleaned annually. In order to properly clean the evaporator, you can follow this guide. 

Step One 

At the front of the junction of the main air duct, remove the foil insulation. Foil insulation can be worn out so if it needs replacement, you should do so. The foil insulation should be taped using a duct tape. Remove the tape carefully because you will need to replace it once you are finished cleaning the air conditioning unit. Behind the insulation, you can be able to access the plate. It is usually anchored in place using a few screws. You can simply unscrew and remove the plate. 

Step Two 

Using a utility brush, clean the evaporator’s under part. If you can’t reach that area, you can try sliding the evaporator outside just a little. The evaporator tray can actually slide out even though it’s connected by pipes. 

Step Three 

Clean the evaporator’s tray since it carries condensation from the component. In order to remove as well as prevent future growth of fungus in the evaporator tray, pour one tablespoon of chlorine bleach right into the tray’s whole. You can also check the tray for clogs. If it has water in it, you can use a heavy wire or a coat hanger to remove its clog. 

Step Four 

You can now reattach the plate after putting the evaporator back to its original place. After that, tape the insulation. 

Step Five 

Turn the unit back on and try checking if there is any leakage. If any leak occurs, seal them using a duct tape.  

Maintaining the Condenser 

Most of the times, the condenser component is placed outside your house. It routinely collects airborne dust, debris from surrounding plants and trees, as well as dirt. There is a fan inside the condenser unit and its job is to circulate air throughout the coil. This component should be cleaned regularly. Before you shut down the power of the air conditioning system, try checking for the air movement’s direction to find out if there is something wrong with your condenser. To clean your air conditioner’s condenser, follow this step by step guide. 

Step One 

Remove any vines, weeds and grass that are growing around your ac’s condenser as they may be interrupting or blocking the airflow. 

Step Two 

Using a coil cleaner, clean the condenser appropriately. Instructions are usually provided by the manufacturer about how to use the cleaner. Clean the coil by flushing it with water – but never use a hose. Let the coil dry before you proceed to the next step. 

Step Three 

Using a brush, you can dust the fins in order to remove the dirt that has already accumulated through time. It may also be necessary to remove your ac’s outer grill so that you can be able to reach the fins. Never use a garden hose to clean the fins since water could also cause the dirt and dust to clump and would even result to the fins compacting in mud.  

During the winter, the condenser unit’s outside part should be protected from winter weather conditions. To prevent leaf blockage or ice damage, you can cover your air conditioner with a specialized condenser cover that is designed to withstand any weather condition. 

While it is easy to maintain your air conditioner, it is still best to hire professional air conditioner repair service because they are the most experienced and knowledgeable in this field.
