Ductless Mini Split Installation: Why You Should Leave it to HVAC Professionals

installing a ductless mini splitDuctless mini splits have received a lot of attention in recent years for their exceptional energy efficiency and streamlined design that offer versatile installation options. Read on to see what you can do to prepare for ductless mini split installation and which steps are best left to your HVAC professional.

Ductless Mini Split Components

Ductless mini splits are often configured as air-source heat pumps that utilize the same refrigeration principles of transferring heat energy in and out of the home at the heat-exchange coils for both heating and cooling. However, in lieu of cumbersome equipment of central heat pump systems, ductless systems utilize advanced features, which make for big efficiency and comfort gains, and it’s all squeezed into three primary components.

  • Indoor air-handling unit (AHU) is a sleek and stylish cabinet containing the indoor half of the split system.
  • The outdoor unit contains the inverter-driven (variable speed) compressor, coil and other components.
  • A thin, connecting piping system that's routed through the walls, attic and/or crawl space connects the outdoor unit to the AHU.

Ductless Mini Split Installation

Ductless mini split installation varies according to the selected mounting option of the AHU and the location of the outside unit. Keep these design tips in mind for best performance:

  • The outside unit should be installed on firm footing (e.g. small concrete slab or wall mounted).
  • The outside unit should be protected from snow and ice, perhaps with a small awning or mounted to the home shell.
  • The shorter the distance from the outdoor unit to the AHU, the greater the efficiency.

With these tips in mind, you may position the outside unit near the installation mark, and do the same for the AHU. You can drill a hole about 3 inches diameter in the home shell. Or you can wait to see what your HVAC pro recommends in regards to installation details.

The sophisticated electronics of ductless systems, drainage and refrigerant charge require the skills and licensing of an HVAC professional.
