Do you live in a house or work in a building where all the rooms are not utilized equally? If so, you are paying to heat and cool the entire space and only need to cool a few rooms. Depending on how large the space is, you could be wasting a lot of energy each month paying to cool or heat unused zones. A solution to this problem is a type of HVAC system called mini-splits. Mini-splits are heating and cooling systems that allow you to control the temperature in individual spaces. Basically, it gives you the option to set the temperature in different rooms or sections inside your home or office, and this can lead to big savings on your monthly bills.

How does it work?

A mini-split system works like a regular HVAC system, only it doesn’t have ductwork. It consists of:


An outdoor compressor/condenser

The outdoor unit is designed to remove hot and humid air from your home or office. It is equipped with a fan and condensing coils, and circulates excess heat and moisture outside.

An indoor handling unit

It suspends from the ceiling or mounted high on a wall and sends conditioned air directly into the designated space. It is connected to an outdoor compressor by a refrigerated line.

A remote

Because the indoor unit is attached to the ceiling or high on a wall, you use the remote to control the unit.
In a regular HVAC system, the large unit is located outside the home or in the attic. Ducts carry your home’s air to a central location, where it is cooled and then returned to your home via air ducts. But in a mini-split system, the indoor unit is located inside the room or zone that it is cooling. This indoor unit is very small and installed on the ceiling or side wall of the area it is assigned to cool.
The indoor mini-split system has cold evaporator coils inside. The unit takes the warm air that is inside your home or office and runs it over the cold evaporator coils that absorb the heat. It brings the heat to the small, outside unit where refrigerant dumps all the heat it pulled from the inside air. It basically pulls the warm air from inside the home and blows cool air back inside.

Benefits of mini-splits


They are a lot smaller than the typical HVAC system


Unlike central heating and cooling systems, mini-splits do not require ductwork


Mini-splits provide both heating and cooling by using a pump, which is more energy efficient


They are rated very high in energy efficiency. In fact, they have a 20+ SEER rating (cooling efficiency) and a 10+ HSPF rating (heating efficiency)


Mini-splits are a more affordable option if adding on to a room. Instead of having to add ductwork and expand your current HVAC system, you can install a mini-split system and save time and money.
