If you don’t have access to central air conditioning in your home, you might need to install a window mounted air conditioner to make it through the summer months.
While having a central air conditioning system is very convenient, having separate units in different rooms can have its advantages. You could install a more powerful unit in the rooms where the sun hits more directly, and some choose to use fans to redirect the air from an air conditioning unit to other areas.
You have many options to choose from, and the units can be found all the way up to 23,000 BTUs. The thing to consider if you go with a unit that is 10,000 BTU or more is that they can be very heavy. It is a good idea to have some type of additional support for the unit to make sure that it is securely attached. It should also be installed in the shade if at all possible, to make it more efficient.
