Mini-splits – Heating and Cooling

Mini-splits provide heating and cooling to homes and outbuildings without all the expense of installing an HVAC system. They are a single unit that provides both heating and cooling. In comparison to an HVAC system, where you need an AC and a furnace, a mini-split does both. 

The Benefits of mini-splits 

Mini-splits have many benefits, and those include:

  • They do not require ductwork – For custom home builds or renovations, you can put the cost of ductwork into other upgrades.
  • They are perfect for add-on rooms – those without an HVAC connection – Converting your attic to an office or bedroom? You can add heating and cooling via a mini-split without investing in the ductwork. 
  • Can cool or heat multiple rooms – Some have zone systems based on their remote control. 
  • Do not require natural gas or propane – So, your heating and cooling bills may drop.
  • Mini-splits are easy to install with minimal construction. – With a bit of electrical and plumbing experience, mini-splits can be a DIY project. 
  • Are less expensive to run than an HVAC system
  • They are available in multiple sizes so you can pair the right size and energy efficiency to the area you need them to service. 

How Much Space Will A Mini-Split Service? 

Mini-splits are available in different BTU sizes. Expect that a 12,000 BTU unit will heat or cool around 500 square feet. A mini-split that is rated at 36,000 BTUs will heat or cool a space that is around 1,500 square feet. 

Mini-splits come in BTU ratings from 9,000 BTUs to 36,000 BTUs giving homeowners a range of options for choosing the right mini-split to service their heating and cooling needs. 

A tip for sizing mini-splits is to focus more on the area you need to heat or cool. Sometimes, it is more efficient to install two mini-splits to cover different areas of your home, than to expect one mini-split to cover all the space efficiently. 

Maintenance Needs of Mini-splits

A mini-split unit needs only an annual service call to keep it in top shape. With an HVAC system, you would need to have the AC serviced before the warm season, and the furnace serviced before the cool season. 

The maintenance needs of a heating or cooling appliance are often dictated by the terms of its warranty. Be sure to check out the warranty when choosing between similar units and brands. 

Are mini-splits worth it? 

Mini-splits are worth the investment; however, they can require more energy in weather that is below 47°F. A mini-split will continue to work well in temperatures as low as 5°F but they require more energy to function. 

Mini-splits also can handle cooling when the outside temperature is over 110°F. 

The range of outdoor conditions that mini-splits handle makes them applicable to many climates around Madison, WI. They have a lower cost per unit than most HVAC systems, and you don’t have to pay for the labor, material, or installation of ductwork. Mini-splits are also a good option if you are expanding a home or doing renovation work and do not want the added expense of running ducting to new units or renovated space. 

Overall, mini-splits are affordable options over more complex heating and cooling systems. With an HVAC system, you would pay for the AC and the furnace, but with a mini-split, you are paying for just one unit.
