Heat Pumps & Mini Splits [Ductless Systems]

Efficiency is always a priority goal when it comes to home heating because a more efficient way costs less than something inefficient. For us, one way to increase efficiency is by using a ductless system. A ductless system is composed of one outdoor heat pump and one or more evaporator units indoors - more than one evaporator unit is called a mini split system.

The heat pump’s job is to either take away heat from the house or bring heat in from the outside - it all depends on the homeowner. Now, you may be asking yourself: what makes a ductless system more efficient? Well, heat is simply energy and that energy is gradually reduced or lost as it makes its way around the house via extensive air ducts.

Installing a ductless system is an easy job for our trained specialists. The installation primarily revolves around the setup of the outdoor pump with the indoor unit. Having a ductless system in the home is advantageous because of the versatility. You can choose which rooms to have these systems so that you’re not wasting money by heating unoccupied rooms.

The installation may be quick but it can take longer depending on how intricate you want the system to be. You may choose to only have one outdoor pump and one indoor unit but you can always choose a mini split system to create multiple zones inside your home.
