What Is A Ductless Mini Split?
There are many variations on the mini-split systems, and they can be broken down into two different types: packaged and unitary.
Packaged units typically include the evaporator coils, blower fans and condensers in one package commonly mounted on a wall of an unheated area. In contrast, the indoor fan coil is usually mounted inside an interior closet or on a wall.
The packaged models may vary from manufacturer to manufacturer, but they will always include all parts needed for installation.
Unitary systems do not have condenser coils or outdoor fans; rather, they will include only an indoor fan coil with factory-mounted refrigerant lines and an electrical connection.
An air conditioner's capacity is measured in "tons" (12,000 BTU equals one ton of cooling). A "heat pump" or "reverse cycle" can heat as well as cool; these are typically referred to as 2-1/2 or 3-ton units.
A 5 Ton Ductless Mini Split System:
The most common mini-split systems will come in sizes ranging from 1-ton (12,000 BTU) up to 5 tons (60,000 BTU), although some larger low ambient capable models can go even higher than that! Mini-splits are available for both residential and commercial applications. You would generally use a single-zone system; a two-zone system would be used for a larger space such as a living room and bedroom or office space.
The majority of mini-split systems have built-in wall mounting brackets that will allow the installation of an air conditioner to be reasonably simple if you know what you are doing. If not, it is recommended that you get a qualified contractor familiar with mini-splits to ensure it gets done correctly.
Some things to consider when installing your mini-split unit: The "low voltage" wiring connections should only be attempted by those who know how to work safely with electrical wiring; an improper hookup could turn your whole house into a live wire! Be sure the installation location you choose has adequate ventilation and airflow to keep the unit from overheating.
As with any electrical device, it is required that a licensed electrician perform all of the wiring associated with your ductless mini split installation.
How Much Do They Cost?
The most common factors in determining the cost to install a mini-split are your home's location and whether or not you will require a separate outdoor condensing unit. If a wall is in the way, an indoor mounting bracket must be purchased in addition to labor costs that may incur.
In some cases, if exterior walls are concrete or brick, that can add time and labor expenses for proper sealing of lines between inside and outside so there isn't a loss of efficiency from air leakage. Make sure your contractor budget's enough time before they begin work on estimating installation costs of your new ductless mini-split.
