A Packaged Terminal Air Conditioner (PTAC) is the solution to the problem of cooling extra spaces in your home. You may be thinking about how to cool as well as heat your room that you have just added to the house. This extra space may not get cool and heat efficiently as your current HVAC may not have that much capacity. Moreover, the ductwork for your HVAC can be costly. PTAC units are commonly used in hotels as a cooling system as well as a heating agent. One of its main advantages is that they are energy efficient and inexpensive means of heating and cooling a room. There are a variety of sizes and prices in which PTAC units come. The price of a PTAC unit ranges from $388 to $533 US Dollars. These units are available through commercial distributors only.

Step 1 - Find a Suitable Location

The PTAC unit can be installed inside an existing window frame or you may choose another site too. The thing that you should check is what is outside the window or wall on which you are planning to install your PTAC unit. In order to make sure that the unit is able to cycle hot air out and intake cool air, leave a clearance of about 6 to 8 inches. Check that there is no shrubbery or hedges resting on the exterior of PTAC unit. A finished opening is required by a PTAC unit. From side walls, a clearance of 4” should be maintained. When frame walls or a brick surface is to be used, use wood studding to surround the case so that installation screws can be firmly anchored.

Step 2 – Secure the Case

In order to install the unit, you should slide the metal casing into wall spacing or a window. By screwing the sides into studs, the wall sleeves should be made firm. Make sure that you don’t drill into the bottom of the casing. As condensation is gathered in a pan which is present at the bottom of the unit, so try to secure the case over that.

Step 3 – Plug In

There is an outdoor grill in the wall sleeve for the outdoor venting. Push the chassis into place after securing the wall sleeve. Now, the unit is ready to be plugged in. The fan and thermostat controls can be adjusted now.

Step 4 – Caulk

To ensure an air tight seal, all the four sides on the exterior of the case should be caulked.
