A Ductless Mini Split is an HVAC unit that heats and cools a room or open space.
They work the same as large HVAC units but are built smaller to fit into a variety of scenarios.
For example, they make great units to add to a home addition, garage, or small home.
What is a Heat Pump?
A Heat Pump is a unit that can both heat and cool.
While technically all air conditioning units are heat pumps, in HVAC heat pumps refer to a unit with a reversing valve to heat when it becomes cold.
Heat pump units work the same as air conditioners only reversing the mode when it is time to heat instead of cool.
This makes heat pump units very popular since they not only cool in the summer but heat in the winter.
Benefits of a Mini Split
Today’s Mini Split units are low-cost items to both buy and operate.
They cost much less than larger HVAC units, are quiet, last longer, and have very good energy SEER ratings.
There are also many popular DIY kits since no high-cost HVAC company is needed to install one for a handy person.
The SEER ratings on new units are also very good, which makes them cost less to operate.
This low operating cost has many installing 2-3 units on large homes, which can drastically bring down heating and cooling bills.
Downside of a Mini Split
Mini split units don’t blow air through ducts and only heat or cool the room they are in.
The temperature in the rooms next to the unit is affected depending on the insulation.
Since they blow out air only in one room, more than one would be needed to cool a whole home.
It is common to see more than one mini split on a home, often with 1-3 units strategically placed.
How Does a Mini Split Work?
The main components of a mini split are the inside evaporator, outside condenser, and line-set.
Two small copper lines called a line-set to go between the inside and outside units transferring refrigerant.
This allows a mini split to transfer heat or cold into or out of a home, depending on the temperature setting.
Types of Mini Splits
There are many mini split manufacturers, from home DIY kits to dedicated units sold to HVAC companies.
In the past, most all units would only be available to an HVAC company, but now most all units can be bought online.
This is good since a homeowner can do research and read reviews to find the best unit for them.
