Installing an Air Conditioning Unit

How does AC work? When you think of a central air conditioning unit, you probably think of a huge unit that sits in the middle of a big warehouse. That warehouse would be able to maintain temperature control all day long. The same principle applies to air conditioners as they are essentially large industrial units that are cooled by an evaporative cooling fan.


How does Central AC work? Central AC works by using ductwork and registers (fixtures) to transport hot air from outdoors, to the unit. Essentially, the machine pulls hot air from the outside, cools it in the unit, and then pushes it through the house via the ducts. Although you may have seen pictures of huge machines that look like giant air conditioners, these are just industrial machines. A new central air conditioning unit is a lot simpler and more energy efficient than the old units were. The newer units are also more reliable, more durable, and easier to install.

Before installing a new system in your warehouse or factory, be sure to check the existing ductwork and electrical wiring to make certain that you can still obtain power during a power failure. You should consult with the manufacturers of the AC equipment to see if your existing wiring and ductwork will be adequate for your new unit. It will also be necessary to upgrade the insulation on the building’s walls and floors to ensure proper ventilation. If you are planning on using a gas furnace for your new system, you will need a carbon monoxide detector and testing kit.

How is AC powered? Your new air conditioner works on AC (alternating current) which is provided by your local utility company. AC is converted into DC (direct current) by a set of coils in the wall and floor of the buildings. These coils to convert the AC to the alternating current needed to warm and cool the rooms. The AC then passes through a control circuit before it reaches the compressor to convert the AC into cooled air.

Are there any special preparations that need to be made before installing a new AC unit? If so, these preparations should be made prior to beginning the installation process. First, any existing insulation must be removed and any loose tiles or insulation must be properly secured. Next, any plumbing that is involved in the heating or cooling of the space must be isolated and no fixtures should be installed where water pipes enter. Any vents that are open should also be closed.

Any equipment in your heating and cooling system should be unplugged prior to hooking up the AC to the units. Also disconnect the electrical connections from the components. This includes all of the air conditioning and heating unit’s controls. Also, before hooking the units up, any wires that are part of the heating and cooling system should be disconnected. It is very important that any wiring be correctly terminated to prevent any potential electrocution hazards.

Some individuals are intimidated by the prospect of having their new AC unit installed. If this is the case, then you may want to consider hiring a professional installation technician. Many experienced contractors will come into your home and complete the job with no fuss or bother, saving you the time and aggravation of trying to do it yourself.

Finally, the contractor will install the new system. He or she will also set up the new unit according to the HVAC industry specifications. After the installation process is completed, your new system should operate at its maximum efficiency. Following these installation techniques should help to ensure the optimal performance of your new system.
