MiniSplit Sizing

Most homeowners who are looking at Mini-Split projects may be able to guesstimate the sizing needed for their heating & cooling project. There are a few main datapoints that we, as Minisplit installers, look at to assess the system size:

  • Size of the area
  • Insulation coverage
  • Window coverage
  • Intended function of the minisplit

 

Most mini-split systems come in 6,000 BTU increments (half-a-ton). Typically, the smallest indoor unit size is 6,000 BTUs and can be as high as 24,000 BTU’s. Most mini-split outdoor units have a capacity range between 6,000 – 60,000 BTUs.

 

We recommend having the sizing and assessment completed by an HVAC professional so the system is properly sized and working towards meeting the projects needs. We have compiled a simplified range of capacity for indoor minisplit units that you can find below.

Do You Need An Electrical Panel Upgrade?

If you considering a minisplit system, it’s a common concern that other expenses or upgrades that may be required that can increase the overall cost.


To simplify, each mini-split outdoor unit requires two free spaces in your electrical panel; The minisplit indoor units get their power from the outdoor condensing unit and do not require additional circuits.  The electrical scope required for mini-split installation is typically one 208-220v circuit with an amperage that commonly ranges between 15 amps to 40 amps. If you don’t have free spaces in your electrical panel, a panel replacement may be necessary. In certain cases, as allowed by electrical code, certain circuits may be condensed in the panel so a full upgrade may not be required.


In projects with a tighter budget, installation of an electrical sub panel is a relatively cheaper alternative to an electrical panel upgrade; Adding a subpanel is common for installing mini-splits and done on a daily basis.


A Full Electrical Panel Upgrade can tack on an additional cost anywhere from $3,100 to $5,200 depending on the level of complexity to install or alter. An Electrical Subpanel Installation may cost as little as $1,500 to $2,000 and above.

MiniSplit Unit Types

  • Wall-mounted units: These units are mounted on the wall and are typically the most common type of indoor unit for mini split systems. They can be mounted at any height on the wall and are ideal for cooling a single room or small space.

  • Ceiling-mounted units (aka Cassettes): These units are mounted on the ceiling and are often used in commercial or industrial settings where there is limited wall space but plenty of ceiling space. They are also used in larger residential spaces where multiple indoor units are needed to adequately cool the space. Typically, to fit a minisplit cassette into a residential property, there needs to be 16.5″ of joist clearance. This joist size is uncommon in houses built before the 2010’s.

MiniSplit Outdoor Unit Location

The outdoor unit of a ductless air conditioning system is typically placed in a location that is easily accessible for maintenance and repair, and where it will not be obstructed by trees, bushes, or other objects. It is also important to ensure that the outdoor unit is properly ventilated and has adequate airflow around it.

 

 

In general, the outdoor unit is placed on a concrete pad or other flat surface that is level and able to support the weight of the unit; wall-mounting the outdoor unit is also a common option that helps to save space.

 

 

It is important to note to follow local codes and regulations regarding the placement of the outdoor unit, as these may vary depending on your specific location’s regulations.

MiniSplit Heatpump Types

A regular mini split heat pump is designed to operate efficiently in moderate climates, where the outdoor temperature typically stays above freezing. In these conditions, the heat pump can easily extract heat from the outdoor air and transfer it into the indoor space, providing both heating and cooling as needed.

 

A cold climate mini split heat pump, on the other hand, is specifically designed to operate efficiently in colder climates, where the outdoor temperature may drop below freezing. These units are equipped with special features that allow them to continue to extract heat from the outdoor air even when the temperature is very low.

 

Some of the features that may be included on a cold climate mini split heat pump include a low ambient temperature kit, which helps the unit to start and run at lower temperatures, and a defrost cycle, which helps to prevent ice from forming on the outdoor unit.

 

Cold climate mini split heat pumps may also have a higher heating capacity than regular mini split heat pumps, as they are designed to provide sufficient heat even in very cold conditions. They may also be more expensive to purchase and install than regular mini split heat pumps.
