First, we’ll give you some information on mini split heat pump systems. If you’re good to go on the what’s and why’s, then jump down to our top 10 ductless mini split system list and reviews. On the other hand, if you’re thinking through ductless mini split vs. standard split system heat pumps, the upfront information will be of use.

What is a Ductless Mini Split Heat Pump System?

A ductless mini split HVAC system includes two main component types. The first is the outdoor unit called a condensing unit. It contains the compressor which cycles refrigerant through the system to move heat from one location to another – either into or out of your living space.

The second type of equipment is one or more indoor air handlers. The air handlers are connected to the outdoor condenser by refrigerant lines, a power cable and a condensation drain line.

Mini Split Sizes: Outdoor condensing units are available in 9k to 60k BTUs. The one you choose will depend primarily on the amount of space you need to heat and cool but also the layout of your home, how well your home is insulated and your climate.

Single vs Multi-zone Systems: A single zone system, meaning it has one air handler, can be used in a single room, apartment, small home with an open floor plan, or a converted attic or garage. They are ideal for cottages and cabins too.

A multi-zone system, a system supporting two to eight air handlers, can be used to heat and cool an entire home or other building with clearly defined rooms/zones.

Did you know? Air handlers, the indoor units, are available in 9k to 30k BTUs.

Each indoor air handler is installed in a specific area or room, referred to as zones, and all handlers are connected to the outdoor unit. Each air handler can be independently controlled with a thermostat or remote. Your HVAC contractor can help you decide where to place the air handlers to provide the most effective and energy-efficient layout.

Can the total capacity of the air handlers/indoor units exceed the capacity of the condensing unit? Yes, it can, but it should not exceed it by more than about 15%. For example, if you need a 36,000 BTU condensing unit for a three-zone installation, the easiest choice would be three 12,000 BTU air handlers for a total of 36,000 BTU.

But if one of the zones is larger, installing a 15,000 BTU air handler (9% over capacity) or 18,000 BTU (16% over capacity) air handler in that zone would be acceptable. Just keep in mind that you’ll still only get 36,000 BTU of heating and cooling across the multiple zones.

This is where the thermostats for each zone come in very handy. Reduce the heating/cooling in a zone not being used, so you have sufficiently warm or air-conditioned air in occupied areas.

How a Ductless Mini Split System Works

A mini split provides heat, air conditioning, dehumidification, and the flow of fresh, filtered air.

When the mini split is in air conditioning mode, the air handler pulls the warm air from inside your home over cold evaporator coils where heat is absorbed by the refrigerant. The heated refrigerant is pumped outside where it disperses the heat. The cooled air is sent back into the living space.

When the system is in heating mode, the refrigerant absorbs heat from outside and brings it inside where it is released in the coil in the air handler. It is then blown into the room. Due to the thermodynamic properties of refrigerant, heat can be absorbed from the air in outside temperatures as low as 20 F below zero.

However, as the outside temperature sinks, your mini split heat pump will lose efficiency and effectiveness. Still, the physics of refrigerants are very impressive!

Why Choose a Ductless Mini Split System?

Ductless mini split heat pumps are heating and cooling systems that can be installed in a home without central ductwork. That is a huge advantage in terms of installation ease and cost.

They are a good choice if your home has hot water or radiant heat, or if you put an addition on your home and don’t want the expense of adding ductwork. They can also be used in areas where supplemental heating or cooling is needed – many homes have rooms far from the central air handler that always seem to be cool in winter and warm in summer. They’re ideal locations to be served by a mini split heat pump.

Cost of Ducted vs Ductless HVAC:

If you want to add heating and air conditioning to a home without central ductwork, your options are to install a standard split HVAC system plus central ductwork or skip the hassle and expense and install a mini split system.

Installing ductwork plus the heat pump will cost between $10,000 and $25,000 in a typical 2,000 to 2,500 sq. ft. home. Prices for a ductless mini split are between $4,000 (for a large single zone unit) and up to $18,500 (for a large multi-zone unit).

The initial costs aren’t greatly different, but a ductless mini split has lower upfront costs and will be much more efficient than a central system, saving you money on energy bills every month. It is easy to see that ductless/mini split HVAC systems are the equipment of the future in most climates – even in those with cold winters.

How a Mini Split System Differs from a Standard Heat Pump

Mini splits differ from theregular air heat pumps in that standard split systems rely on central ductwork to circulate the warmed or cooled air through the home. A ductless mini split does not require any ductwork, of course.

Installation steps include holes about 2 inches in diameter drilled through exterior walls to accommodate the connections between the outside and inside units. These are the refrigerant line set, electrical power supply and drain line that drains away condensate accumulating during an air conditioning cycle.

Ductless Mini Split Options

Mini split heat pumps offer a wide range of options that allow you to tailor your system to fit the layout of your home or other area you want to heat and air condition.

In open areas, a single-zone system, or a two-zone system with one indoor air handler at each end of the space is ideal.

In areas divided into smaller rooms, a multi-zone system or multiple single-zone systems make more sense, depending on the size of the rooms/zones.

Here is an overview of your equipment choices.

Compressor/Condenser capacity: 1.0 ton to 5.0 tons, or 12,000 to 60,000 BTUs. In most systems, the largest size is 48,000 BTU.

Air Handler capacity: 9,000 to 30,000 BTUs per handler.

Efficiency – 18.0 SEER cooling efficiency and 9 HSPF heating efficiency to 42 SEER and 15 HSPF. The higher the rating, the more efficient the unit. In our opinion, the growing efficiency ratings of mini split and even standard air source heat pumps will continue to threaten the geothermal heat pump industry and cause prices of geothermal systems to become increasingly competitive.

Installed cost range: $4,000 (single zone) to $18,500 (multi-zone)

Average Cost: A four zone, 36,000 to 48,000 BTU system installed will cost $9,500 – $13,500.

Choosing and Configuring a Ductless Mini Split System

Before you choose a mini split system, you need to know the square footage of the entire space you need to cover and the square footage of each of the zones included. These measurements will give you direction on the total capacity required and the size of the air handlers for each zone.

Then you will decide on the design of the system, the number and size of air handlers, and where they should be placed in the home to provide the most efficient layout. The dealer or an HVAC contractor can guide you in configuring the best system.

Sometimes you can find a complete package that includes the condenser and the needed number of air handlers, but most often, you will purchase the compressor/condenser and air handlers separately.

This gives you the flexibility to choose the best condenser for your needs and the number, style, and BTU level of each air handler.

Note: The total BTU capacity of the air handlers should only slightly exceed the total BTU capacity of the condenser. For instance, with a 48,000 BTU condenser, ideal choices for air handlers would include four 12k air handlers (48,000 BTU total) or three 18k air handlers (54,000 BTU total).

Below are some common condenser and air handler configurations:

18,000 BTU Condenser: (9k + 9k) or (9k + 12k) air handlers

24,000 BTU Condenser: (12k + 12k) or (9k + 9k + 9k) air handlers

36,000 BTU Condenser: (12k + 12k+ 12k) or (18k + 9k + 9k) or (18k + 12k +9k) air handlers

48,000 and 60,000 BTU Condensers: Once you get into the high BTU levels, there are a range of combinations for air handler configurations depending on the number of zones you need to cover. With 48,000 BTUs you can cover 5 or 6 zones and with 60,000 BTUs can cover up to 8 zones.

Tip: You can place the higher BTU air handlers in rooms you need the most temperature control. Also, in very hot climates, you will need higher BTU air handlers to maintain comfort.

The indoor air handlers are available in a variety of installation options:

Wall Mounted – These work well in all room types. They are the most affordable and come in several styles.

Ceiling Mounted – Installed in the center of a room or zone for optimal coverage of the entire area, ceiling mounted units work well if you have limited wall space.

Ceiling Cassette – These are recessed into the ceiling and are the least conspicuous option.

Floor Mounted – These units are installed low on the wall near the floor and are a good option when wall space is limited, or you prefer the air handlers be less conspicuous. Floor units tend to have higher capacity too.

Concealed Duct – These are installed into existing ductwork just inside the air grate.
