- Front Panel
The front panel is the part that is seen by a person from inside the room where it is installed and has a user-interface control, which can be used electronically or mechanically. As a rule, an older unit is of mechanical control type with rotating handles to control the air conditioner’s temperature and fan speed.
- Interior Parts
These components are found inside of your window AC unit:
- Cooling Coil
This component comes with an air-channel mounted on it. In this part, the heat exchange occurs between the unit’s refrigerant and the room’s air.
- Fan Blower
This part is a diffusive evaporator blower to release the cold air to the room.
- Capillary Tube
Such a tube is utilized as an extension gadget. It tends to be boisterous during activity whenever placed too close to the evaporator.
- Operation Panel
It is the component that controls the temperature and speed of the fan blower. The thermostat detects the return air temperature and another to screen the temperature of the cooling coil. Sort of control can either be mechanical or electronic.
- Filter Drier
A filter drier is used to eliminate the dampness from the refrigerant.
- Drain Pan
The drain pan of an air conditioner contains the water that condensates from the cooling coil and is released into the open air by gravity.
- Other External Parts
Aside from the front panel, these are the components found outside your AC unit:
The compressor is utilized to squeeze the refrigerant.
While an evaporator coil absorbs heat from indoor air, a condenser coil is a component that releases heat from the refrigeration to the external atmosphere.

Knowing What to Clean
An essential thing to consider on how to clean a window air conditioner without removing it is that you don’t have to go over all the parts. There are specific components you need to focus on because many features are hidden. While it’s enticing to break out a splash cleaner, cloth, or pail of foamy water to cleanse your window AC unit, that could be a significant misstep.
Each air conditioner unit that sits in a windowsill will have a filter, and it’s anything but difficult to track down. It is not generally easy to clean but instead needs legitimate consideration if you need to keep your unit running at top proficiency. The filter lies behind the grill, which should be cleaned once in a while, albeit a quick visual assessment tells you when is the right time.
The front panel, including the control board, is another zone to focus on. However, it will differ from one model to another. Its cabinet will take some misuse from the components outside and could require occasional TLC relying upon the conditions where you live. Other main apparent parts that are easy to clean or access in most models are drain pans and plugs.
Maintaining your air conditioning unit clean can keep you from dealing with the interior parts. However, some internal components, such as the evaporator coil, fan motor, and blower, can sometimes be filthy. It is the usual AC problem during the offseason or put idle for a long time. Hence, it is good to store your AC unit properly if used only during summer because motors are one of the most expensive components to fix or replace.
Prepare the Things to Use
Before touching any part of your AC unit, prepare first the cleaning materials you will use to do the process efficiently. In window air conditioner maintenance, you will need the following:
- Spray Bottle
- A bucket filled with water
- Hydrogen peroxide
- A dry towel
- Tap water
Start with The Filter
The first step is to know how to clean window ac filters. Unplug the unit and remove the front panel or grill to get the filter. While some models have filters that you can simply pull from the side, others need the effort to take it out. Either way, you should carefully get it without breaking the grill to avoid more replacement problems. After removing the filter, you need to check the manual to see if it will require a replacement.
Moreover, a vacuum cleaner with a decent accessory might be the effortless method to clean the filter in your window AC unit if it’s just dusty. However, if you have a messy launderable filter, such as LG, Haier, GE, and others, you should use warm water with a gentle cleanser. When you feel fulfilled, you’ll need to shake off the water from the filter and permit it to air dry.
Dusting the Grills
In some air conditioning units, dust and dirt are not visible because of the color. You can swipe a dry towel to see if you should proceed. If you want an easy way to clean it, you may take it outside and hose the dirt off. You can also use mild spray cleaners or soak it with a detergent to remove tough dirt. Most importantly, let the grills dry before installing it back in the unit.
Rinsing the Cabinet
The cabinet of a window AC unit is the housing of its interior parts that protects it from weather conditions. To clean the inner side of this component, you can use a damp rag or sponge. In any case, you may require a somewhat more real effort if your unit hangs in a window for quite a long time or more than one season.
For this outdoor job, you need to unplug the unit first and assess if your hose’s length can reach it. Practically showering down the outer part of your AC unit weekly will keep it much cleaner than you might expect and keep gunk from working up consistently. To eliminate dust or stains, you should use a scour brush with a mild cleaner.

Washing the Drains and Pans

On the off chance that your AC unit has a hose associated with the drain port on the back, eliminate it.
