How Much Does an Air Conditioner Cost?

 
As summer approaches, you might be thinking that it's time to get a new air conditioner. Before you go out air conditioner shopping, however, perhaps you should get a sense of how much is this is actually going to cost you.
Central air conditioners are the most expensive of all of the available units, costing many thousands of dollars. But some small portable AC units can cost you as little as $100.

To get a high-quality portable AC unit from a top manufacturer, you can expect to spend anywhere from $300-$700. These are the most expensive of the non-central air-conditioners. You will pay a premium for the convenience of a portable AC unit.
Bear in mind, however, that Consumer Reports doesn’t actually recommend any portable AC unit. CR has tested portable air conditioners and its reviewers argue that portable units don’t cool as well as they claim.
A brand-name window air conditioner, however, is can be priced much more reasonably, running anywhere from $150-$400 for a low level of BTUs (under 8000 BTUs, for example) while a larger capacity unit can run anywhere from $400-$800. Finally a through-the-wall model can cost you anywhere from $300-$1500.

In terms of installation costs, these can vary widely depending on which type of air conditioner you plan to buy. For example, portable and window AC units require no special installation. So once you buy the unit, it that is all that you will spend except for, of course, the monthly electricity bill. A window unit might require some minor installation, but you can do it yourself and it won’t cost much at all.
For moderate installation costs, consider a through-the-wall unit. To install one of these air conditioners, you can expect that the cost will be under $300. This is pretty low because these units don’t require ductwork.
When shopping for a central AC system, the cost of the unit and installation increase considerably. If you already have a furnace in place and the duct work is already done, you can expect that adding a new central air conditioner to your home will cost about $3500-$4500. Of course, the price will vary depending on which brand you buy, which model you choose, and how big the cooling capacity is.
If you have to put in new ductwork as well as install the AC unit, the price of installing central air can jump up to $8000. If this is the case in your home, you might consider going with a ductless mini split system, which does not require ductwork.
If you're replacing old central air conditioner, bear in mind that there may be higher costs involved because the installers may need to fix the insulation in the older ductwork. 

This is important because you did not want the cool air to leak out of the ducts if they are poorly insulated. This can happen if the cool air is escaping the ducts and not making it to you room. This can cost you a ton of money and energy bills.
