All systems have a point where repair is no longer enough. For the central air conditioning in your home, you have a few options for replacement. One is to remove the air conditioner and heater and install a heat pump.
Since air conditioners and heaters are usually installed simultaneously in a new home, they will likely be ready for replacement around the same time. With a heat pump, you can take care of all your heating and cooling needs, throughout the year, with a single unit.
