The Ultimate Guide to Window AC Units Installed in Walls

Different Types of Window AC Units

Window AC units installed in walls come in various types, each with unique features and benefits tailored to specific applications. Whether you seek sleek designs, efficient cooling, or noise reduction, these units offer tailored solutions for your cooling needs.

  • Through-the-Wall Units: These units are permanently installed in an exterior wall, providing a neater appearance than other types. They offer high cooling capacity and are ideal for large rooms or spaces with limited window access.

  • Wall-Mounted Units: Similar to through-the-wall units, wall-mounted units are installed on an exterior wall but protrude slightly from the building. They blend seamlessly with the wall, maintaining an aesthetically pleasing look. These units are suitable for medium-sized rooms.

  • Casement Air Conditioners: Designed for casement windows, these units are mounted horizontally above or below the window frame. They are compact and easy to install, making them a popular choice for smaller rooms or spaces with limited vertical space.

  • Slider Air Conditioners: These units are inserted into a sliding window and extend only slightly beyond the window frame. They are convenient to install, but their cooling capacity is lower compared to other types. They are suitable for small rooms or as supplementary cooling in larger spaces.

  • Double-Hung Air Conditioners: Double-hung units are installed in double-hung windows, the type that slides vertically. They are mounted on the lower portion of the window and extend slightly into the room. These units offer good cooling capacity and are suitable for rooms with double-hung windows.

Types of Wall-Installed Air Conditioners

When choosing a window AC unit for your wall, you’ll encounter various types, each with unique features and applications. Let’s dive into the key differences between five popular options:

Through-the-Wall Air Conditioners

These units, also known as through-the-wall units, are permanently installed by creating an opening in your wall. With their external condensers and evaporators entirely located outside, they maximize cooling efficiency and minimize noise inside your home.

Wall-Mounted Air Conditioners

Unlike through-the-wall units, wall-mounted units are mounted on an existing wall. They have an indoor unit that houses the evaporator and a separate outdoor unit for the condenser. This type offers flexibility in placement and efficient cooling.

Casement Air Conditioners

These units are designed for casement windows that open like doors. They are installed in the window opening, with the evaporator facing inside and the condenser outside. Casement ACs provide good cooling capacity and convenient access for maintenance.

Slider Air Conditioners

Similar to casement models, slider air conditioners fit into horizontal sliding windows. They are also installed in the window opening, with the evaporator inside and the condenser outside. This type is ideal for easy installation and good cooling for smaller spaces.

Double-Hung Air Conditioners

These units are designed for double-hung windows that have vertically sliding sashes. They are installed in the upper or lower sash of the window, with the evaporator facing inside and the condenser outside. Double-hung ACs offer good cooling capacity and flexibility in placement.

Components of a Window AC Unit Installed in a Wall and Their Vital Roles

When scorching summer heat makes life unbearable, a well-functioning window AC unit can be your saving grace. To ensure optimal cooling performance, it’s crucial to understand the essential components that make these wall-mounted wonders work their magic.

At the Core: The Compressor

Think of the compressor as the heart of your window AC unit. It plays a vital role by compressing refrigerant, a special gas that absorbs heat. This process kickstarts the cooling cycle, sending the refrigerant on its journey.

Condensing Coils: The Heat Transformer

Positioned outside the wall, condensing coils resemble a radiator. As the refrigerant flows through them, the heat absorbed inside the unit is released into the outdoor air, leaving behind cooler refrigerant.

Evaporating Coils: Cool Breeze Generator

Inside the window AC unit, the cooled refrigerant enters the evaporating coils. These coils absorb heat from the indoor air, transforming it into cool and refreshing air that you can enjoy.

Refrigerant: The Invisible Transporter

Refrigerant is the lifeblood of a window AC unit. It continuously circulates throughout the system, absorbing heat inside and releasing it outside, transferring heat away from your living space.

Blower Fan: Airflow Manager

The blower fan is responsible for circulating the cooled air throughout the room. As it spins, it draws in warm indoor air and directs it over the evaporating coils, where it’s cooled and released back into the room.

Filter: Air Purifier

The filter in a window AC unit plays a crucial role in maintaining indoor air quality. It traps airborne particles, such as dust, pollen, and pet hair, ensuring that the air you breathe is cleaner and healthier.

Thermostat: Temperature Watchdog

The thermostat monitors the room temperature and automatically adjusts the unit’s operation accordingly. When the desired temperature is reached, it signals the compressor to turn off, saving you energy.

Remote Control: Convenience at Your Fingertips

Most window AC units come with a remote control for added convenience. With a flick of a button, you can change temperature settings, adjust fan speeds, and even turn the unit off without leaving your favorite spot on the couch.

The Inner Workings of a Window AC Unit: A Step-by-Step Breakdown

In this section, we will delve into the heart of a window AC unit installed in a wall, focusing on its crucial components and their indispensable roles in providing us with cooling comfort.

The Compressor:
The tireless heart of the cooling system, the compressor is responsible for compressing the refrigerant gas, raising its pressure and temperature. This energized gas then carries the absorbed heat away from the room.

The Condenser:
The condenser acts as the radiator of the AC unit. It receives the compressed, high-pressure gas from the compressor and releases the absorbed heat into the outside air, turning the gas back into a liquid state.

The Evaporator:
Located inside your room, the evaporator is where the magic happens. The low-pressure liquid refrigerant enters the evaporator, absorbing heat and moisture from the air, turning into a gas in the process.

Refrigerant:
The refrigerant is the lifeblood of the AC unit, circulating through the system to absorb and release heat. As it evaporates and condenses, it carries the heat away from your room and outside.

Blower Fan:
The blower fan is the unsung hero, circulating the air throughout your room. It draws warm air into the evaporator, where it is cooled, and then distributes the cooled air back into the room.

Filter:
Acting as the lungs of the AC unit, the filter traps dust, pollen, and other airborne particles, improving air quality and ensuring efficient operation of the unit.

Thermostat:
The thermostat acts as the brain, constantly monitoring the temperature and turning the AC unit on or off as needed to maintain the desired temperature.

Remote Control:
The remote control provides you with convenient control over your AC unit, allowing you to adjust settings, switch between modes, and set timers from the comfort of your couch.
