Cleaning the air conditioner is a major step in maintaining the efficiency and the usability of the unit. Therefore, it is highly advisable to know the different steps in keeping your unit clean and free from any leaks and dirt that may hinder the unit from functioning well.
Here are some of the steps on how you can easily clean and maintain your air conditioner.
First things first
Make sure to turn off the unit before you do anything to prevent electrocution. For those who are not familiar with the do’s and dont’s of handling electric appliance, please be cautioned to seek help or guidance from someone who has an in-depth understanding of the product.
Clean the Evaporator
If the evaporator of your air conditioning unit is accessible, it is advisable to clean it annually. However, if the plenum (closed space used for airflow) is covered with a sheet metal box, do not try to open it.
For those who have accessible evaporator, you can remove the foil-wrapped insulation and remove the tape cautiously. Remove the screws and lift off the plate. Using a stiff brush, clean the lower side of the evaporator. You may also use a big hand mirror to make sure that you can clean all areas.
Next, clean the tray below the evaporator by pouring one tablespoon of household bleach to avoid fungus growth. Once you have cleaned this, you can now reinstall the plate and put the unit back into place. If you find any leaks once you turn on the unit, you can seal it by using a duct tape.
Check and clean the condenser
The condenser of an air conditioning unit is prone to dirt and airborne dust. In order to make sure that the condenser is functioning well, you can clean it by using commercial coil cleaners that can be bought from HVAC-R supply stores.
See to it that when you clean the condenser, you clean the fins carefully with the use of a soft brush. A fin comb may also be used to straighten any bent fins.
During fall and winter seasons, make sure to cover the outside condenser units to protect them from ice damage and leaf blockage.
Maintaining the Freon
Sustaining the refrigerant of the system is crucial because once it malfunctions, it affects the efficiency of the unit. If the insulation is damaged, it will not cool down the establishment properly. Thus, it should be replaced. Have a professional replace the damaged coolant line insulation as soon as possible. Do not attempt to charge your unit’s refrigerant lines by yourself.
Test/Replace the Thermostat
You can find the thermostat of your air conditioning unit behind the control panel. You can test or replace the thermostat by removing the grille and control panel from the unit. To make the replacement or testing easier, tag the location of the sensing bulb before you uninstall the thermostat.
Test the thermostat by using an ohmmeter and turn the temperature control dial to the coldest setting. The thermostat is functioning properly if the meter reads zero, however, if the meter reads higher than zero, you must replace it with a new one but of the same type.
Check the Fan
If the fan is noisy or if it malfunctions, it may have dirty or loose blades that can be solved by cleaning or tightening them.
Open the cabinet of the unit and clean any debris with a soft cloth and vacuum. Check if the fan has loose blades and tighten them by using screwdrivers, if necessary. To check if the fan is defective, use an ohmmeter. You can know that the motor is running properly if the meter reads between 3 to 30 ohms. If the reader is at either zero or a high number, you have to replace the motor immediately. Although you can change the motor by yourself, it is more advisable to have a professional check and change it for you to avoid any untoward incidents.
