If you are looking to retrofit a home with air conditioning that doesn't have existing ductwork, you may find that ductless AC is the perfect solution to your problem. The system is very simple to install in your home, though it helps to have a heads-up on what you can expect during the installation.
Ductless AC Requires Wall Space
One thing you need to keep in mind is the amount of wall space that ductless AC requires if you want the system installed. Every room that will be air conditioned needs to have a fair amount of space on the wall for the air conditioning unit. More specifically, each unit takes up a space that's about 3 feet wide by 1 foot tall.
If you do not have the free space on one of your walls, know that you are going to run into problems with installing ductless AC. Keep in mind that you can install one of the units near the ceiling, which will allow all the cool air to fall down to the bottom of the room in the space that you occupy.
Keep in mind that the indoor AC units are not physically installed into the wall. They are actually hang similar to a picture frame. It requires some drywall screws to keep each unit in place, which is all it takes to prevent it from falling down.
Ductless AC Requires Outdoor Space For The Condenser
You need to have a condenser located outside your home to power the air conditioning system. These units are installed on the exterior wall of the home, and are about 2 feet by 2 feet in size. The outdoor condenser is able to power several indoor air conditioning units, and if you have a very large home, you may need two condensers installed.
Ductless AC Is Connected In Several Ways
There will be a refrigerant hose that travels outside your home that connects to each room unit, which is how the refrigerant cycles through the system and cools the air. Every component of the system, both inside and outside, is hardwired to your electrical system. This means that your indoor AC units are not going to take up an electrical outlet in your room. Condensation lines will need to be installed in each room that lead to outside your home, which will help remove condensation that the inside units produce.
