There are many small AC systems that can be used in place of a central AC system. Window and portable units are popular, but there are also some a few different types of wall-mounted units to consider. This article compares wall units to through-the-wall units. These new systems are similar in many ways, but they have some important differences that you want to consider.
Interior wall-mounted units are those that are powered by electricity and can be mounted to the inside of any wall. Basically, these are the same as portable units, except they are mounted from the wall, rather than standing in the middle of the room. Many people like having wall units because they are out of the way and there are no cords to trip over. However, a wall-mounted unit has no connection to the outside of the home. That is, is uses electricity to pump cold air, but it doesn't suck heat out of the room and disperse outside of the home like a traditional AC unit does. Having the entire system on the interior of the home usually results in a less effective unit. These systems have very limited range and can only work in small rooms.
Through-the-wall units are connected to the outside of the home. That is, on the inside you will have the same pump that blows cold air into your home, but the outside will have an evaporator wear warm air can be dispersed. Basically, this results in a far more fluid exchange of heat and a more efficient system. But, while an interior wall mounted unit can simply be hung from the wall, a through-the-wall unit, as the name implies, needs to be installed through the wall. Basically, you need to create a hole in your wall for the unit to fit into.
This level of construction is often too much for homeowners and they prefer just have interior units. However, if you are willing to have a permanent unit that can be seen from both inside and outside of your home, you can enjoy greater efficiency. Through-the-wall units, with their two-part operations (condensation and evaporation) will provide more cold air for less money.
Of course, you will need to spend more cash on their installation, but you will save money in the long run. You can run a more comfortable and greener household with a through-the-wall unit. Contact a company, like Day's Appliance Repair Heatg & Air Condtng Co, for more help.
