Salt Lake City-area homes with furnaces that heat the home with forced hot air do so through a ductwork system. Therefore, if you live in an older home with a furnace but no central AC, air conditioning installation is fairly straightforward.
However, when you have a boiler, your home has either radiators or radiant heat tubes beneath the floor, so there is no ductwork. For this reason, if you decide in favor of central air conditioner installation, you will need to add ductwork to your home. This adds quite a bit to the cost of your air conditioner installation, but it’s almost always feasible, and it makes your home much more comfortable and valuable, which is important if you ever want to sell it.
