Ductless Air Conditioning/Heat Pumps Complete Information

How does a Ductless Mini-Split Work?

Mini-Split units are comprised of an indoor and outdoor unit, this allows for a quieter and peaceful inside environment b enabling yourself/contractor to install louder components like compressors and motors outdoors.

Copper tubing running through a small 2 1/2-3" opening in the wall or ceiling easily connects the indoor and outdoor units.  Freon is cycled through the lines from the outdoor condensing unit to the indoor air handler, where the air is quietly distributed to the interior space.

Conventional air duct systems tend to be bulky and can require special structural attention while Mini-Split system piping can often be routed through walls and joists to maintain aesthetics.   

Keep cool the sensible way.

Hot air rises and cold air falls.  Keep this in mind as we explain how mini-split air conditioners use this principle to cool more efficiently.

In a central air conditioning system cold air originates many yards from its cooing destination, usually in a basement or a hot attic space.  This means cold air, as it travels through ductwork begins to warm up and can lose up to 25% of its cooling capacity along the way.  This adds up to extra money spent on energy bills cooling spaces you can't enjoy.

Window air conditioning units combine a noisy compressor section with the cooling coil and fan.  This process transfers noise from the compressor section into the conditioned space.  They may seem like a quick fix to the summer heat.  But, they take up your window space and they deliver cold air across the middle of the room, not across the top where the heat is.

Mini-Split Solutions.

All ductless mini-split systems cool the air without ductwork.  This is accomplished by mounting the cooling section compactly on the wall, near the ceiling.  This allows the unit to remove heat more efficiently and deliver cooling directly into the space where you need it.  The compressor section is mounted remotely outside, creating a quiet peaceful space inside.

Central Air Conditioning Problems:	Ductless Mini-Split Solutions:
Must cool entire home when only one room may need cooling.	Cool only the areas you want and not the areas where you are not.
Typical 3 ton homes are not zoned or require complex zoning systems.	Multiple evaporators make zoning as simple as setting a remote control.
Energy wasted in long lengths of uninhabited ductwork means higher energy bills.	Less than 5% cooling loss occurs in insulated freon lines compared with up to 25% through ducts.
Retrofitting homes requires cutting holes in walls, floors, ceilings, or decreasing closet space with ducts.	Requiring just a 2 or 3 inch diameter hole in the outside wall means less mess and better home aesthetics.
Window Unit Problems:	Ductless Mini-Split Solutions:
Window units block the view from almost any window.	All ductless Mini-Split units mount high on the wall so they don't disturb your view.
Compromised security by providing easy access to intruders.	Ductless Mini-Split units provide security, requiring just a 2-3 inch opening to the outside.
Window units add little to your home's resale value but, their inefficiency adds to your utility bill.	Ductless Mini-Split units add value to your home and are more efficient than old window units, saving you money.
They are noisy and unattractive.	They are quiet and attractive
Almost all window units have inconvenient manual control knobs.	Wireless remote controller puts you in control of your own comfort.
