PTAC is an acronym for Packaged Terminal Air Conditioner Units. These kinds of air conditioner units are usually found in hotels and apartment buildings. The unit cools a space through the use of electricity.

There are three standard sizes of PTACs: 42x15, 36x15, and 40x15. PTACs can last for several years They are normally installed through the wall or on the outside of a building. PTACs are known as unitary units, which means only one unit is needed to provide heating and cooling to the building.

There are several benefits to having a PTAC:

Temperature regulation: Depending on the season, a PTAC can easily be switched from providing cooler air to providing heat. The same basic settings are you used regardless of your room temperature needs.

Installation: A PTAC is easy to install because they only come in a few sizes. Furthermore, it is easier to install a unit that has two different functions rather than separate systems for cooling and heating.

Independent Operations: PTACs only provide temperature regulation to where they are installed, whereas a split system is needed for a whole building. With several PTAcs in certain rooms, you can change the temperature of each room as needed.

PTACs are easy to use because they come with remote controls that easily help an individual regulate room temperature. Some also come with a sleep setting so people do not worry about the possibility of being kept awake by the PTAC's operation.

There is also a benefit to business owners who install PTACs. The unit can be controlled from one location, such as the front desk of a hotel. When people come in to the room and leave at the end of their stay, the person in control of the unit can change the temperature without having to actually enter the room.

PTACs can also be energy efficient and cut energy bills anywhere from 12-20%. However, they are also expensive to purchase and maintain. They have to be cleaned frequently, and although they are energy efficient, the efficiency rating does not equal that of smaller, individual heating and cooling units.

There are four parts to a typical PTAC unit:

A wall case that holds the PTAC chassis

The chassis holds the compressor and the condenser. It also has an adjustable thermostat and fan cycle.

The room side grill is responsible for airflow of the unit.

The exterior grill which is made of heavy gauge.

When you purchase a PTAC, it is best to have a professional install it. There are five parts that are a part of every PTAC installation.

The first part is a louver, a window that is designed to let light and air into a room, but keeps out rain, sunlight, and noise.

Once the louver is installed, the metal sleeve, heating coil, the PTAC, and the room enclosure are installed. A PTAC can be installed against an outside or an inside wall. They can also be mounted in window frames.

There are several places to purchase a PTAC unit. One place is Long Island Hvac contractors
