Simply put, no, you cannot replace your AC unit yourself.

Even if you have the technical know-how to install an AC unit, all of the electrical components add an elevated level of risk to the process. Plus, it takes nuanced HVAC experience to ensure you get the right unit for the size of your house.

Not only can an unsupported air conditioner fall from the building, risking injuring or killing someone below, but there is also a risk of simply dropping the entire unit out the window or down the wall during installation or removal – an annual project for some window and through-wall units.

Though the lifespan of a home air conditioner varies based on many factors, those that are well-maintained should last 10 to 15 years. And by completing regular checkups and repairs – both big and small – many systems can last even longer.

Generally speaking, the average installation will take anywhere from four to eight hours, which means the process of removing the old unit and being able to turn on the new one should be finished within a day.

In ideal situations the air conditioner should be installed on the north or east side of you home, so that your home can naturally shade your air conditioning unit from the sun during the hottest part of the day. The next-best option is under the shade of a tree, preferably one which drop little debris.
