Best Wall Mounted Air Conditioner Option?

Whether summer or winter, you know that it’s hard to take chances with an old, unreliable AC. So, if you’re out shopping for a replacement, getting the right type of system that perfectly fits your application and budget should be your main consideration. Obviously, if you don’t need a major overhaul of your HVAC system, a central air conditioning system is out of the question. A portable unit is not a good choice either when what you need is a more powerful cooling solution. If this is the case, let’s say that your best choice would be a single-zone ductless mini split unit.

A single-zone cooling solution means it is specifically designed for cooling an individual room. The most common room air conditioners are wall air conditioner and window air conditioner. As its name suggests, a window air conditioner is typically installed in a window with a metal bracket or the so-called sleeve, which is used to keep it steady and properly supported. On the other hand, a wall air conditioner is typically placed on a wall as a mounted unit. Take note that window air conditioners can also be mounted on a wall as a through-the-wall unit. Basically, it is installed using the following procedure:

  • Dig a big square/rectangle hole in the wall
  • Have the sleeve ready
  • Position and attached the sleeve in the hole
  • Make sure that the sleeve is properly attached into the hole
  • Mount the unit in the sleeve
  • Insulate the sleeve and/or the surrounding area of the unit
  • Plug the unit into the power source

Make sure that when mounting the unit, it is properly attached into the sleeve. While these seem to be regular steps, they are not as easy as they look. One the main issues with through-the-wall air conditioners (or window air conditioners, in general) lies on installation. With the need for this bracket support and proper insulation, the installation procedure requires a little bit more work and becomes a little bit more complicated. Improper mounting and incorrect placement of the sleeve might cost you some energy dollars and a good level of comfort. The main effect of an improperly installed bracket is a restricted airflow from the unit. Things might get worse if you have poor insulation in the sleeve, which may result to warm outdoor air coming inside the room. If central air, portable, and through-the-wall air conditioners are no so viable as an option, your best choice would be the wall-mounted ductless air conditioners.

What is a Wall-mounted Ductless Air Conditioner?

A wall-mounted air conditioner is a single-room system. Unlike a central air system that requires ducts, complex installation, and usually works by distributing conditioned air through air vents, a wall-mounted unit is easier to install, less expensive, and can be set to cool a specific room, giving you a better chance of achieving precise temperature.

3 Top Reasons Why You Should Use a Wall-mounted Ductless Air Conditioner?

As a single-room solution, using a wall-mounted air conditioner gives you the benefit of having a system that is:

  • Low-cost but highly efficient. Compared with central air conditioning system and other single-room solutions, a wall-mounted air conditioner is not as pricey. What makes them even better is they are most energy-saving. In fact, some of the most cost-effective and energy efficient systems models are wall-mounted units.
  • Simple and easy-to-install. To install a wall-mounted unit, all you need to do is drill a small 3" opening in the wall and set up the piping and cable system to connect the two main units. With wall-mounted mini split system, you don’t need to spend on and install a typically costly and complicated ductwork.
  • Perfectly complements your centralized AC system. If you have an existing centralized air conditioning unit but face heating and cooling challenges in a single room, a wall-mounted air conditioner would be alternative cooling solution.

How to Install a Wall-mounted Air Conditioner?

Thru-the-wall air conditioners are usually sealed in a hole in the wall. For ductless minis split wall-mounted air conditioner, the compressor/condenser unit is installed in a suitable location outside and near the exterior wall while the indoor unit is mounted and fixed permanently on a wall.
