If your Columbia, Mississippi home doesn’t have ductwork, that doesn’t mean your family has to suffer through hot weather with insufficient HVAC equipment. Many options are available for older homes without ducts. Between window AC units and ductless mini-split systems, however, which solution will keep your family more comfortable all year round? Read on to find the answer.

Zoned Cooling

Ductless mini-split systems can cool and heat up to four zones, each with a separate thermostat. You can achieve a similar result with window AC units, but you have to install a separate window unit in each room you want to cool. ACs also lack the added bonus of heating your rooms during winter. Ductless mini-split systems offer zoned cooling from a single system instead of requiring you to get multiple units, as you would with window ACs.


Quieter window AC units are available, but they are still one of the noisiest cooling solutions out there. Anyone who has suffered through a summer with an old AC that causes the windows to rattle will know how loud window units can get. Ductless mini-split systems, on the other hand, are extremely quiet. On average, they make less than half the noise of the typical window AC.

Cooling Capacity

Both ductless mini-split systems and window ACs have the potential to properly cool your home, but they have to be sized correctly to work effectively. A unit that’s too large will cool the room too fast and won’t properly reduce humidity (leaving you with clammy air), while an undersized AC won’t be able to achieve the temperature you want.

Though both types of AC have advantages and disadvantages, if you’re looking for comfort and energy efficiency, a ductless mini-split system is the way to go. Though installation is more expensive, ductless mini-split systems will save you money over time on energy bills. Call AC Southeast® to find a Mississippi HVAC contractor today.
