What are Packaged Terminal AC?
Packaged terminal air conditioning units, PTACs, are typically selected where individual zones have an outside wall and are conditioned separately with individual occupant control. PTACs are well suited to hotels, motels, nursing homes and apartments. As the name implies, a single package contains all the components of an air-cooled refrigeration and air-handling system in an individual package.
Units are designed for through-the-wall installation, with decorative outdoor grilles as an option. Units are also available with various heating options-electric resistance or hydronic. Other variations include the Packaged Terminal Heat Pump (PTHP).
Usually these types of units come with a heating circuit, being electric strips and/or heat pump. They still still make water and it drains out the back, but they do use the water to help cool the condenser coil, so they don't run as much water out of them. On a "normal" summer day, you probably won't see any water, but just like any A/C, on humid hot days they will run water out the back! But they do do a good job of cooling and heating for the price, as long as they are sized correctly!!
How do I choose my PTAC unit?
The three most important things to keep in mind are BTUs, size, and voltage.
What are the pros and cons of a PTAC unit?
PTAC units is an efficient way to cool and heat a room. Since most units are about 42" wide you either need to install it in a large window or have a hole cut into your wall.
