They are usually located in your garage, basement, attic, or a special closet designated for this purpose. When you look at your HVAC system, you only see two boxes, one that is outside your home and the other inside your house, in the garage, attic, or basement. The outer component box is called the condenser, while the inner box is the air handler. But you need to understand what's inside these boxes to know how your central air conditioner works.
The heat exchanger is the part of the air conditioner that heats the air entering the oven from inside the duct network or from outside your home. Gas or electric burners power heat exchangers and use electric coils to heat the air. Like everything in life, when it comes to building homes, money speaks. One reason air conditioning units are installed in attics is because they are cheaper and easier to install.
It's much easier for your installer to leave ducts loose, rather than having to cover and roll them through floors and walls. This saves time, and when your contractor doesn't take as long to finish a project, you also save labor. Attic units save space: As a general rule, new residential air conditioning systems consist of two separate or split units. The outdoor unit, which is what many people refer to as “central air conditioning”, houses only the condenser and compressor.
An indoor unit contains the evaporator and the fan itself. In most cases, the interior component can be installed in a storage cabinet or utility room. Wherever you decide to install your HVAC system, you need to make sure you hire a professional HVAC installation company.
