You may have read the title of this blog post and be scratching your head at this point. How is it that your heating system can even work, yet be efficient if it lacks ductwork? Your air ducts are what bring the conditioned/heated air into your living space from your HVAC systems, after all!
Well, you apparently have not yet heard of ductless systems! The fact is, you’ve probably seen them even if you didn’t recognize them for what they are. Instead of using ductwork, a ductless system includes one outdoor unit connected to up to four indoor air handlers. Each air handler can be controlled independently of one another, and is connected to the outdoor unit via a conduit containing a power line, condensate line, and refrigerant line.
These air handlers are typically wall-mounted above doorways or even floor-mounted in some cases. They are the chosen method of heating for more and more homeowners these days–and we’re about to tell you why below.
Ductless systems are incredibly effective and efficient HVAC systems, and a leading choice for many homeowners throughout Chicagoland, particularly those renting out rooms or portions of their homes. It saves energy, and subsequently money!
There are a number of options to go with when shopping for a new air conditioner. If you already have a central system in place and its aging, or you’re concerned it’s not working efficiently enough, then you may choose to go with an upgraded central system. But what if your ducts are also in bad shape? Should you replace those, too? Well, maybe—but what if we had another solution for you? 
Ductless systems are among the most popular options these days for heating and cooling in modern homes. Rather than operating via a series of air ducts connected to an indoor air handler and evaporator unit, a ductless system breaks up the indoor unit and blower fans to distribute that system throughout your home in the form of individual air handlers mounted on the walls of the rooms they’re needed in.
