When you decide you need a new air conditioning system for your home (and now would be a great time to do it and beat out the worst of the summer heat), you’ll have to make a few decisions. If your previous AC was a standard central system, then the easiest choice is to put in a similar type of air conditioner. You can make upgrades, such as going for a higher efficiency unit or one with a variable speed blower fan. But the new air conditioner will do the same essential job as the last one.
But … there’s another option, which is to install a heat pump. A heat pump is similar to a central AC—and takes up the same amount of space inside and outside the house—but it can switch the way it operates so it can work as a heater when necessary.
