Installation of a central air conditioning system is a complex task that takes a
lot of time, hard work, and skill. Since the job will most likely require you to
tear up floors or take down ceilings to run ductwork, it's best to hire a
contractor to make sure the job is done right. If you try it yourself and aren't
sure of what you're doing, you could end up with a severely damaged home.
Additionally, A/C systems that aren't installed by professionals may not be
covered under your home insurance, should they become damaged at any point. That
being said, here's a look at what the installation process entails:
ComponentsHere's a list of the main
components of a central A/C System:
- Compressor and condenser (outside unit)
- Evaporator (inside unit)
- Ducts
- Pipes
- Exhaust vents
A/C Installation
The first things your contractor
will need to consider are the layout of the ducts and where the inside and
outside units of the system will need to be placed. You'll need ducts reaching
into each room of your home, with exhaust vents located in spots that will most
efficiently cool each room. Larger rooms may require multiple exhaust vents. How
the ducts run through the walls and ceiling of your home will also need to be
carefully considered. They'll need to be navigated along the most direct and
efficient paths possible. Air can lose its coldness if it travels through too
much ductwork.
To prepare your home for the ducts, paths will need to be
cleared along the duct routes. This could mean cutting through joists or
relocating wiring. All throughout this process, your contractor will need to pay
close attention to all pertinent building codes regarding ductwork.
TIP: Sometimes, window air conditioners are a
more efficient and cost-effective option than central A/C, so be sure to check
out all of your options.
In addition to hiring a contractor to do the
installation, you'll probably need to hire an electrician to the electrical
work. Your contractor will probably take care of this for you or at least be
able to give you a few leads on electricians. These professionals should have
your central air conditioning system up and running and your house cooling down
in no time!
