When Should You Use a Ductless, Mini-Split System?

When Should You Use a Ductless, Mini-Split System?Mini-split systems offer remarkable versatility for heating and cooling otherwise challenging spaces. They’re energy efficient, easy to install, and provide a good deal of design flexibility.

A mini split can be a heat pump or an air conditioner. Its two primary components include an indoor air handler and an outdoor condenser, similar to central cooling systems. Unlike central systems, mini splits don’t require ductwork to distribute the conditioned air. Instead, they blow it directly from the air handler.

Their lack of ductwork not only saves space, it also makes them ideal for conditioning garages, home additions, remodeled attics, and stand-alone buildings. Like Ducts, as important as they are in central HVAC systems, do have disadvantages in some situations. Ducts take up valuable indoor space and contribute to air leaks and thermal losses.

Pros of Ductless Mini Splits

  • Mini-split systems install quickly since there is no ductwork. Manufacturers pre-install the refrigerant, which eliminates this step at your home. Once the outdoor condenser and air handler are placed, all the HVAC technician does is connect the two with a narrow conduit that contains the refrigerant, power and the drain line. Smaller mini splits plug directly into a 110 volt outlet.
  • Many mini splits have high energy efficiency ratings, which saves money on heating and cooling.
  • Mini-split heat pumps provide affordable heat without using a combustible fuel. They’re much more energy efficient than electric baseboard or radiant heating.
  • Larger mini splits can support up to four separate air handlers, making it possible to condition an entire home. Each air handler has its own thermostat. When a room isn’t in use, you can turn the air handler off to save energy.

Cons of Mini Splits

  • Mini splits typically cost more initially than other heating and cooling options.
  • These systems work well when conditioning homes with open floorplans. Walls and hallways reduce their ability to distribute the conditioned air.

If you’re remodeling or adding to your home, few systems can match the benefits of mini-split systems. To learn more, contact Cool Power, LLC. We provide trusted HVAC services for Long Island homeowners.
