Split System Residential Air Conditioning
Split system residential air conditioning means that the evaporator air handler is installed inside the building, and the condensing unit with the compressor is installed outside the building.
When a split system residential air conditioning installation is ducted, air flow is distributed through ductwork from the air handler to the rooms to be cooled.
Depending on the installation, return air may flow back to the air handler through return duct,
it may return to the air handler through the space over a false ceiling,
or the air handler may be installed in a small closet in the center of the home, and the air simply flows through the rooms, through the building, and through grills in the closet door, to the centrally located air handler.
With a ductless air conditioning unit, the inside air handler is mounted on a wall, on the ceiling, or it may stand on the floor.
They are designed to cool a room efficiently without ductwork.
I have seen ceiling mount ductless systems with ductwork attatched, and installed solidly mounted inside sheetrock walls.
These installations were to make the unit blend in with the interior decor, and the result was that the ductwork and sheetrock had to be partially demolished to dissasemble the units for repairs and thorough maintenance.
Whatever type of residential split system air conditioning unit you install,
You can save some money by providing plenty of access for technicians to maintain and repair your equipment in the future.
Once again, saving a technician's time saves you money.
As one of my best teachers once advised me to tell my customers, let your pocketbook be your guide.
You can install one large split system residential air conditioning unit for the whole building,
Or you can install two or three or more smaller ones, which would allow you to run only the units you need to keep you comfortable, without having to pay the power bill of running a larger unit.
Give some thought to the design of your building,
the way you use your air conditioning,
and the effect the different types of installations will have on your power bills.
This page has been written to provide a brief introduction to these types of systems.
