If you are building a new home and strive to become more energy-efficient, you probably should install one of the most cost-effective systems to control the climate in each room all year around. Ductless mini splits allow customizing comfort in each and every room. No need to heat the kitchen or the bedroom when your living room or a kid’s room is too cool. Ductless mini splits for new home construction.

Ductless mini split technology offers a new range of efficiency and comfort—benefits that previously required higher cost or added complexity. To help you determine which mini-split system is most appropriate for your new efficient-home construction project, check these benefits and challenges:

Ductless mini splits benefits:

  • Heating and cooling available in every room
  • Conceptually straightforward system
  • Industry-leading technology “cool factor”
  • When properly installed is the most efficient system on the market (as tested by AHRI)
  • Most effective strategy for reducing overall energy use by heating the core of the home with efficient technology
  • Fewer issues with oversized ductless heads in bedrooms
  • Avoid perceived aesthetic concerns with fewer wall-mounted ductless heads

Ductless mini splits challenges:

  • Multiple outdoor units may be necessary
  • Multi-head system can be expensive
  • Choosing the right-sized system for the home can be challenging
  • Operates more effectively in homes with an open floor plan and scenarios where bedroom doors are kept open
  • Some homeowners have a negative perception of an “unsightly wall-mounted ductless unit”

Installing ductless mini splits while walls are still open allows to hide insulated refrigerant piping, communication and power wiring, as well as condensate line within walls. Additionally insulating the wall cavity with fiberglass insulation could be a wise idea to reduce possible noise and heat or cool transfer. The same could be applied to exterior of your new home, as the piping does not have to be exposed to the outside, while it also could be hidden withing exterior walls, well insulated, and pass to outside condenser through a small opening near the bottom of the house.

    I was just looking at your article, and see it should be very popular. I just want to tell you, in case you don’t already know, installing a ductless mini split in new construction is wise idea, cause you can hide all piping away from the eye. I have seen these systems on the existing homes, all piping is installed outside, pretty ugly (sorry, rather unsightly). Thanks for good ideas

    Hey Braklin, do not worry much about condensation. It happens only in 100% humidity, but in such conditions anything, and anyone will sweat. Hell, when it is like 100% humidity I am draining frakin’ “sweatfall”. So let pipes sweat too

    Quick question. I know that refrigerant lines are insulated, but if run inside of walls – do they sweat? Does this insulation, foam or microfiber rubber I guess, stop piping from sweating. I have seen insulated tubing sweating when indoors. If it is buried in the wall and condense water, it will create mold, and all sorts of problems. How to prevent this?

    I was just looking at your Ductless Mini Splits in New Construction, and have a question: is insulating the wall cavity with fiberglass insulation a good idea? I am trying to reduce possible noise and heat gain or loss. The same applies to exterior walls. Please advise
