Ductless air conditioners have a bit of a misnomer. Consumers and homeowners alike make the general assumption that because this type of A/C does not make use of forced air from the furnace or of the home's own ventilation system that no real alterations are made to the home. That is not the case. There are definitely some perks to not having to connect a lot of tubing, hoses, and other parts, to your furnace and the vent system, but you still will need to make the following accommodations to your home for this system (should you choose to purchase it).
The Wall Unit Has to Connect to the Outdoor Refrigeration Unit
There is a unit for ductless A/C that mounts to the wall. You can mount it up high on the wall, or down low if you have a room that is full of windows with little available wall space. Electric wiring and cabling, a refrigeration hose, and another type of cabling have to connect to the back of the wall unit. Your HVAC contractor will drill a hole in the wall about three to five inches in diameter. All of the connecting hoses and cables will travel from the refrigeration unit outside through this hole in the wall and into your ductless wall unit.
Electrical Wiring and Cables Still Have to Be Connected to a Power Source
These units are not self-supplying when it comes to electricity. They do need electricity to operate, too, so that means that all electrical wiring and cabling needed to make them run will have to connect to your main electrical box. If your box cannot handle the power needs of ductless air conditioners, you will need to hire an electrician to upgrade the box before the HVAC contractor can complete the installation of your ductless system.
One Ductless System Can Cool a Couple of Rooms on a Single Floor
These systems are very good at cooling rooms. However, they can only cool a certain amount of square footage, and only on the same level where the unit is placed. Therefore, if you have more than one story to your home and a lot of square footage, you will need to repeat the above installation modifications for each wall unit. The outdoor refrigeration units can handle up to three or four wall units each, depending on the make and model of the outdoor units.

When our air conditioner broke last year, I was fairly confident that we would be left trying to choose a similar system for a bunch of money. However, our friend who works as a general contractor explained that there were all kinds of neat advances in HVAC systems that might help us out. He explained that we might be able to enjoy a quieter system or one that filters our indoor air more effectively. We liked the sound of that, so we started shopping for a new system. After finding an air conditioner that was perfect for our place, we started this blog to educate other homeowners about new technology.
