Ductless Mini Split Installation in Downers Grove, IL
Home | Ductless Cooling
What is Mitsubishi Electric Cooling?
A ductless mini split has three parts. An indoor unit that mounts high on the wall, an outdoor condenser, and a remote. Refrigerant lines run between the two through a hole about three inches across in the exterior wall. That is the whole install. No ductwork and no soffits to build around it.
Because there is no duct, nothing gets lost on the way to the room. A central system pushes cooled air through the whole house and gives some of it up to long runs and leaky joints. A mini split cools the room it is mounted in. Each indoor unit runs on its own setting, so one room can sit at 68 while the rest of the house stays where it is.
Most single zone jobs take a day. Multi zone systems running three or four indoor units off one condenser take longer.

Why We Install Mitsubishi Electric
Rooms a Ductless Mini Split Can Cool
These calls are almost always about one room. A converted attic that never keeps up in July. A sunroom that gets too hot to sit in by noon. Additions off the back of the house that the original system was never sized to cover. Second floors in older houses, where the duct runs were an afterthought and the bedrooms pay for it.
Plenty of houses in Downers Grove run on boiler heat and radiators, so there is no ductwork in them at all. Those get a multi zone system, usually one indoor unit in each bedroom and one in the main living space. We do the same thing in offices and shops where a single room runs hot and the rest of the building is fine.
How Does it Work?
Mitsubishi Electric Cooling products can fit into almost any space because their innovative engineering optimizes the capabilities of the INVERTER technology and R410A refrigerant for more efficient systems with smaller indoor and outdoor units. R410A refrigerant is environmentally friendly, with zero Ozone Depletion Potential (ODP). The units themselves are also made of recyclable materials.
