Ductless or Mini-split systems continue to grow in popularity because they are a great choice when seeking comfort cooling or heating spaces such as offices, lobbies or windowless rooms. This type of unit is usually wall-mounted and paired with an outdoor condensing unit and avoiding duct work makes them more energy efficient as well. The Mini-split systems can be easier to install requiring just a small hole to be drilled during installation leading to reduced problems with security or leakage. When it comes to routine maintenance such as cleaning filters the ductless systems are much easier to access than many conventional AC systems that may be in a crawl space or other difficult to access area. Occupants enjoy the control of being able to enjoy different comfort zones such as producing cooling in one room and heating in a neighboring space. The United CoolAir “CoolSpot” model is another great alternative to accomplish the goals of the ductless system but installed as a packaged unit instead. At 1–3 tons of capacity, this ductless ceiling grid self-contained air conditioning system is offered as an air-cooled, water-cooled, chilled water or Magna cool precision cooling package. The CoolSpot fits easily above the drop ceiling, replacing a tile panel, and provides even air distribution through adjustable louvers and is well suited for laboratories. Additionally, there are considerable cost savings with the CoolSpot compared to conventional ductless split systems on the market.
