Can a Wall-Mounted Air Conditioner be Moved After Installation? An Expert Guide by AirGreen

As Montreal's leading HVAC company, AirGreen recognizes that you need your cooling solutions to be as flexible as possible. So, you may be wondering, can a wall-mounted air conditioner be moved after installation? Let's dive deep into this topic.

Understanding Wall-Mounted Air Conditioners

Wall-mounted air conditioners, increasingly popular in Montreal, are renowned for their efficiency, affordability, and compact design. As the name suggests, these units are installed on the wall, typically at a high level, to distribute cool air evenly around the room.

Moving Wall-Mounted Air Conditioners: The Basics

The short answer is, yes, a wall-mounted air conditioner can be moved after installation, but it is not a simple task and is not generally recommended. The process is complex and requires professional HVAC skills to be done safely and effectively.

Understanding the Installation Process

When a wall-mounted air conditioner is installed, a series of steps is followed:

  1. Choosing the ideal location for the unit, which includes evaluating sunlight exposure, electrical connections, and airflow patterns.
  2. Installing the mounting bracket, ensuring it is level and secure.
  3. Making a hole in the wall for the piping, electrical wiring, and drainage tube.
  4. Mounting the unit onto the bracket.
  5. Connecting the indoor and outdoor units using the pipes and wires.

Each of these steps is calculated and precise, making the process of moving the unit post-installation complicated.

Risks and Considerations

There are several reasons why moving a wall-mounted air conditioner after it's been installed is not typically advised:

Risk of Damage

The process of unmounting, moving, and remounting the air conditioner carries the risk of damaging both the unit and your wall. Professional technicians have the expertise and tools necessary to minimize this risk, but it is still present.

Efficiency and Performance

The location of a wall-mounted air conditioner directly impacts its efficiency and cooling performance. Moving the unit to a less ideal location could lead to higher energy consumption and reduced cooling capacity.


Moving a wall-mounted air conditioner requires professional assistance, which can be a costly service. It's often more cost-effective to properly plan the initial installation than to move the unit later.

Need for Redecoration

Since the installation of a wall-mounted unit involves drilling holes in the wall, relocating the unit may leave unsightly holes that need patching up and redecoration.

When Moving Might be Necessary

There are scenarios when moving a wall-mounted air conditioner might be necessary:

  1. Redesign or Renovation: If you're planning to remodel or renovate your space, the air conditioner may need to be moved to accommodate the new layout.
  2. Performance Issues: If the current location of the unit is leading to inefficient cooling, relocation may improve performance.
  3. Repair or Replacement: If the unit requires significant repairs, or if you're replacing it with a different model, it might be necessary to change its location.

In such cases, always enlist the help of an HVAC professional. At AirGreen, we have a team of skilled technicians ready to assist you.
