How Is Package Unit Installed?

 Before we delve into the installation of packaged units it is important that we understand the basics of a packaged unit. To put it simply, a packaged unit contains both the heating and cooling systems one at a time. Such units are more suitable for homes which do not have enough indoor space either for a furnace and coil or an air handler. The specialty of packaged units is that all their parts are contained in one outside unit that sits either on one part of the roof or in one side of the building. Generally, packaged units are available in two different footprints that is the small and the large. The size of footprint that is required for a home depends on the tonnage and the installation requirements of the particular building.

When it comes to the installation process, it is seen that packaged unit of a smaller footprint can be installed quite easily while the larger unit has the advantage of more installation flexibility. If you want you can install a larger footprint either on the roof or on a slab while a packaged unit of smaller footprint can be installed only on a slab.

 Before a packaged unit is finally installed there are some pre-installation check points that need to be kept in mind. They are the following:

• The installer should carefully check the structural length of the supporting members
• There should be adequate provision for servicing of the unit as and when required
• There has to be uninterrupted power supply along with good air duct connections
• Proper draining facilities are also a mandate for the installation of a packaged unit

Once these pre-installation checks are done, the next important aspect is to choose the location. It is mandatory that the location is on a solid foundation preferably a concrete slab or a rooftop. In case you are installing the packaged unit on a slab it must be kept in mind that it is above the ground level and the surrounding area needs to be conducive for drainage. The heat pumps of the packaged unit has to be installed in areas which has continuous snow accumulation or areas which is exposed to subfreezing temperatures for long period of times.

 The next important aspect in the installation of a packaged unit is the ductwork. It is a better idea to use the industry given manuals when you are sizing or designing the duct system. Overall it needs to be kept in mind that the unit has to be placed close to the space which has to be either heated or cooled. Ducts should clearly run to supply and return outlets. Similarly, all wiring should be done in accordance to the law to avoid all kind of difficulties at a later stage.

Once the installation is complete you should never try to run the unit in a voltage lower than the one mentioned by the manufacturer. Last but not the least, even if you do the whole thing all by yourself getting a professional contractor to check it once is a better idea.
