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:

The Size of the Area to Heat / Cool (Square Feet)
Your Local Climate (Is it sizzling hot or icy cold for prolonged periods?)
Insulation (From drafty spaces to snug havens, insulation plays a crucial role)
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.

Can I mix and match Wall Mount and Ceiling Cassettes Air Handlers?

Yes, of course! Get in touch with one of our HVAC experts and we can put together a custom package for you.

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:

Heating: 5°F to 75°F (outside temperature)
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.

Bought 3 already!

So far I've purchased 3 of these units. And they all work really well! Very happy. HVAC Kingdom make things easy for me

Highly Recommended HK!

Great pricing at HVAC Kingdom and the system itself is quality and easy to install! I did most of it myself and just got an electrician to do the electrical work

Just What I Needed

Got this mini split installed and did a significant amount of research before hand. MRCOOL was the way to go because they were the only true DIY on the market. HVAC Kingdom helped me pick the right size system for my space. Friendly staff and lightning fast delivery!

Very happy with everything!

Had installed a unit at my home so knew what to expect. Install went reasonably smooth . There up and running and daughter is happy. Performing as expected

Great product - no complaints!

I've had this installed for a few weeks and so far no issues!
