Ductless Mini Split Installation: Not for Amateurs, but You Can Do Some Pre-Installation Work Yourself

ductless mini splitMany homeowners love the idea of saving a buck with do-it-yourself projects. In many cases, the results are just as good as a professional contractor’s work. When it comes to installing a ductless mini split, it’s possible to get the project started on your own, but it’s important to have a trained HVAC technician do the “heavy lifting.”

Ductless mini splits are essentially heat pumps that warm or cool your home by quietly blowing the conditioned or heated air directly into a room. Mini splits are the perfect solution for retrofitting a historic home without the cost and hassle of installing intrusive ductwork. In fact, many new homes are being built with ductless technology, thanks to the energy efficiency, convenience and savings associated with it.

What Does Installing a Ductless Mini Split Entail?

Fully installing a mini split system requires specific tools and knowledge that are nearly impossible for a layperson to acquire. In addition, in most areas, one must be certified to work with the gas, refrigerant and electrical connections needed to complete installation.

It is possible, though, to do some pre-installation work on your own before your trusted contractor finishes the job. Homeowners with some construction experience and basic tools should be able to:

  • Drill the three-inch hole in the wall where the unit will be placed
  • Run the copper tubing and connections outside
  • Hang or install the indoor air handling unit
  • Unpack the compressor from the box
  • Prepare a concrete pad or other flat surface
  • Place the outdoor compressor unit on the flat surface

To ensure proper installation, leave at least the following jobs for a professional contractor:

  • Setting gauges
  • Completing the couplings
  • Vacuuming the lines
  • Testing for leaks in the tubing
  • Releasing the refrigerant
