For people who live in a moderate climate, residential apartments, and compact spaces, it is fairly easy to install a wall-mounted AC unit and manage it all year long.
These systems follow a ductless and compartmentalized approach, yet the energy efficiency is much higher than ducted air conditioning systems. Before you buy a wall-mounted ductless AC unit, make sure you know the basics given here.
Installation of Wall-Mounted Air Conditioner
A wall-mounted air conditioner is the easiest to install compared to a central air ducted system. It requires a solid wall strong enough to hold the mounting plates, and you can place the indoor unit anywhere in your room. However, remember that it should be around six feet high on the wall and not face a door directly.
For better air circulation, keep the layout of your room in mind so that nothing obstructs the airway. For the outdoor condenser unit, you can place it anywhere outside your home with a clear heat exchange zone. There should be no plants or walls around the outdoor unit, only a few feet of clear air to release the heat.
Working On A Wall-Mounted Air Conditioner
A typical wall-mounted air conditioner is the indoor half of a ductless mini split. It hangs high on an inside wall and connects to an outdoor unit through a small hole, about 3 inches across, that carries two copper refrigerant lines, a power and control cable, and a condensate drain line. No air travels through that hole.
The indoor unit’s fan pulls warm air from the room across a cold coil. Refrigerant in the coil absorbs the heat, the compressor in the outdoor unit pumps that heat outside, and the cooled air blows back into the room. In heating mode the same system runs in reverse as a heat pump.
Most of the efficiency comes from two things: an inverter compressor that slows down instead of switching on and off, and the absence of ductwork, where central systems lose part of their cooling through leaks and hot attics.
Benefits Of A Wall-Mounted Air Conditioning Unit
If you want to lower the energy costs while prolonging the life of your AC, a ductless AC unit could be your best option.
- No Ductwork Hassle: A wall-mounted AC unit requires no ductwork for cooling. It is a single unit that can operate extremely well in small spaces. You can save your money by investing in this system.
- Better Cooling Control: Ductless AC units provide you complete control over cooling. These individual units work for one room, leaving all other places warm.
- Energy Saving: The wall-mounted units are fixed on the wall with no air gaps behind them, unlike window AC. Thus, you can save both energy and money by investing in this system.
Cost of Installing A Wall-Mounted Air Conditioner
The price of a wall-mounted mini split depends on how many indoor units you need, the size (BTU) of each one, the length of the refrigerant line run, and whether the electrical panel needs a new circuit. A single room is the lowest-cost job; a multi-zone system for a whole house costs several times more.
