Ductless Mini Split Air Conditioner System

Ductless mini split air conditioners, also known as ductless air conditioners or ductless mini split systems, are all the rage these days.  They have been on foreign soil for quite some time but, until the last ten years, not so much in the United States.  Think of a Mini Split as a window air conditioner on steroids.  Then take that window air conditioner and chop it in half.  Now you have a ductless mini split air conditioner.  We regularly sell and install ductless mini split air conditioners throughout the Orlando area.

When Might A Ductless Mini Split Air Conditioner Be A Good Choice For You?

Ductless mini split air conditioners are a very good choice in cases where ducts cannot be run.  I just installed one today near downtown Orlando where the customer converted a garage into a office.  The roof was flat too install air ducts.  Another great advantage of ductless mini split air conditioners is the energy savings over a forced air system.  Energy is expensive, which means that if you save electricity, you save money.  The forced air system uses up to thirty percent more energy than a mini split just to transport the air through the ductwork.  The mini split has no ducts, which means that it costs less money to run, particularly in a smaller space.

Cool Only Where And When You Need Cooling

Another savings of electricity on a ductless mini split air conditioner is that it is, by its very nature, a zoned system.  When a room is occupied, the evaporator for that room can be turned on, and when leaving that room you can turn it off,  just like a light switch.  Every space can have its own evaporator and be turned on and off when needed, as opposed to a central air conditioner, which is designed to condition many rooms at one time.

Mini splits are flexible in that they can be additions to existing central air conditioners if a home or business expands beyond the capacity of the existing system, yet the new space is too small for a central system.  Beyond using mini splits as additional capacity units, homes and businesses are using them to satisfy the whole space conditioning.  This second setup requires a larger outdoor unit (condenser) which consists of the compressor, the coil and fan motor.  The outdoor unit may be a three ton unit paired with a combination of indoor evaporators that total three tons.  The indoor unit may have 3 one ton evaporators, or 1 one ton with 4 half ton evaporators or a variety of other combinations.  This type of setup, including the ductless mini-split, is very efficient.

Installing Ductless Mini-Split Air Conditioners Is Not A DIY Activity

Installation is not as simple as the advertisements suggest.  There are refrigeration and power lines that need to be connected from each indoor unit to the outdoor condenser.  The outdoor condenser needs power run to it from an electrical panel.  A electrical disconnect needs to be at the condenser.  The condenser needs to be mounted on a stand or platform on the ground.  Each indoor evaporator needs to be mounted to the wall with a hole or chase running through the wall or ceiling for the pipes, wire and drain line.  A condensate line needs to run from the evaporator to a place where water can go.  Sometimes the drain needs to be pumped by a pump which requires its own installation and power source.  Once everything is in place, the refrigerant lines need to be pressure tested for leaks.  Any leaks must be repaired.  If no leaks are present, the system must be vacuumed down to pull out all air. Then the valves need to be opened to let the gas flow from the condenser into the rest of the system.  At this point, electricity can be engaged and the system checked for proper operating temperatures, pressures and electrical consumption.  Also the condensate drain system must be observed to ensure proper flow of water.

A Final Word Of Warning About Ductless Mini-Split Air Conditioners

Many companies are selling ductless mini split air conditioners online to consumers directly.  However, these units must be installed by a licensed Orlando HVAC technician or the warranties on these systems are voided (not to mention you probably will not know how to install them yourself in the first place, as you might have deduced from the installation description above).  And most Orlando HVAC companies will not install these when purchased directly by the consumer.
