FAQ's

What size DIY Mini Split do I need?

Get ready to tailor your comfort with precision! Here's what you need to consider:

  1. The Size of the Area to Heat / Cool (Square Feet)
  2. Your Local Climate (Is it sizzling hot or icy cold for prolonged periods?)
  3. Insulation (From drafty spaces to snug havens, insulation plays a crucial role)
  4. Basic Sizing based on Square Footage alone:
  • 9K BTU = 180 to 375 Sq Ft.
  • 12k BTU = 376 to 500 Sq Ft.
  • 18k BTU = 501 to 750 Sq Ft.
  • 24k BTU = 751 to 1,000 Sq Ft.
  • 36k BTU = 1,001 to 1,500 Sq Ft.

What is the operational temperature range for DIY Mini Splits?

The operational temperature range for DIY air conditioning units varies based on whether it's a Multi-Zone or Single-Zone system:

Multi-Zone:

For the 4th Gen Multi-Zone 18k – 36k condensers:

  • Heating: -13°F to 75.2°F (outside temperature)
  • Cooling: 5°F to 122°F (outside temperature)

For the 4th Gen Multi-Zone 48k condensers:

  • Heating: 5°F to 75.2°F (outside temperature)
  • Cooling: 5°F to 122°F (outside temperature)

Indoors, at the thermostat:

  • Cooling: 62°F to 90°F
  • Heating: 32°F to 86°F

Single-Zone:

For the 4th Gen Single Zone 12K – 24k condensers:

  • Heating: -13°F to 75°F (outside temperature)
  • Cooling: -13°F to 122°F (outside temperature)

For the 4th Gen Single Zone 36k condensers:

  • Cooling: 5°F to 122°F (outside temperature)

Indoors, at the thermostat:

  • Cooling: 62.2°F to 89.6°F
  • Heating: 32°F to 86°F

What can I do about the excess coil/line set length?

It is recommended to leave the remaining/excess line set coiled horizontally near the condenser and wrapped with protective tape. This will not impact performance whatsoever.
