One of the most common alternatives to ducted forced-air heating and cooling systems in modern homes is the ductless mini split system. Rather than operating through a network of air ducts connected to an indoor air handler and evaporator unit, ductless systems basically break up the indoor unit and blower fans—air handlers—and distribute conditioned air into the individual rooms of your home, independently of one another.
If you’ve ever been in a friend’s home and seen something up on the wall that sort of resembles a window AC, but doesn’t go back through the wall, what you’re looking at is part of a ductless system. Those wall hanging units are hooked up to a single outdoor cabinet, creating a central heat pump system, but without ducts.
For most people, spring is the time to schedule some preventive maintenance for their air conditioners in preparation for summer. For some people, however, no amount of maintenance will be enough to get their system through another summer. In times like those, all you can really do is replace the system entirely. If you’re looking for a new system to replace your old air conditioner, you should consider all the options available. Changing the type of air conditioning system you use might fit your individual needs a lot better. A ductless system, for example, might just be the perfect air conditioning solution for you.
