Having them installed will cost between $3,000 and $4,000. AC installation contractors can sometimes install the entire air conditioning system in around four hours or so.

Fire Hazards

Your AC unit has the potential to start a dangerous fire in your home if it overheats. To prevent this terrifying possibility, follow the maintenance tips above and avoid using extension cords near your air conditioner.

Another common mistake you can make is buying a unit that does not suit the size requirements of your home. If you purchase one that’s too small, it will not properly cool the area. On the other hand, if you go with a unit that is too large for the size of your living space, it will not cycle properly.
