Most homeowners report spending between $3,736 and $7,185 to have air conditioning installed. This price is more typical of a central A/C unit installation rather than a window central air conditioner addition which typically averages about $300. Your total cost for the job will depend on the type of system you choose.
The size of your home will determine the type of air conditioning system you will need.
There are several types of systems, including:
Window units: installed in windows as a singular A/C system unit
Split systems: either as mini-split (ductless) or central systems that are installed as inside and outside units
Central system: uses duct system that's usually combined with the heating system to cool a whole house
Portable units: comes as a split, hose or evaporative system for ease of movement around the house
A window air conditioning unit will generally suffice to keep a smaller home cool on warm spring and summer days. The cost to install a window air conditioner averages between $150 and $300, depending on the size you need. Installing a window air conditioning unit can bring added comfort for a reasonable price, but it will be less powerful than a central air conditioning system. If you have a bigger home with multiple rooms, you will probably need to have a central air conditioner installed.
