Many people are finding that mini split heating or heating and cooling units are gaining in popularity and most people have probably heard that these ductless heating systems are more energy efficient than central heating and other types of heating options. But are mini splits really good for heating homes and businesses?

To answer that question, you first need to understand what a mini-split heating system is and how it works.

Mini-split systems are comprised of a compressor or condenser that is located outside of the home or building and an air handling unit that is located indoors. The two parts of this system are linked together by a conduit that consists of a power cable, a condensate drain, refrigerants and suction tubing. In most cases mini split heating uses hydraulic power (such is found in hot water heaters) or they use propane or kerosene like space heaters may use.

When considering ductless mini-split for your home or business there are several things you will need to consider.

  • First, you need to consider the winter temperatures where you live. Areas that have frequent low temperatures during the winter months will need a larger size pump to meet those lower temperatures or else you will need to use other sources of heat along with the mini-split heating system to keep rooms in your home at a comfortable temperature when the weather gets really cold and temperatures drop below 0 degrees.
  • Second, if you live in an area that gets snow fall you have to make sure that you can mount the outside portion of unit off the ground and place a roof over it that still allows air to circulate, but prevents the unit from getting covered in snow.
  • Third, while many people place their indoor unit high up on the ceiling if you live in a colder climate you may want to place your unit closer to the floor since warm air rises you want the heat from unit to be lower so that the lower level of room will be warm as well.
  • Fourth, the initial cost for installing mini splits can be quite expensive. While this cost is made up in energy savings over time, the upfront cost may be prohibitive for some people.
  • Fifth, mini split heating allows you to select the amount of heat you want and need for specific rooms or zones in your home. Unlike central heating where every room needs is set for the same temperature mini-splits allow you to keep little used rooms set a lower temperature saving even more energy.
  • Sixth, It can be quite difficult to find a trained HVAC professional that is qualified to installed a ductless mini-split system making this system cost even more.

Mini split heating works best for homes that have an addition added on or in older homes where is there is no or limited space to put in duct work. Ductless mini-splits may also be better for small apartments or homes rather than larger homes.
