See Costs Near You

Mitsubishi mini split systems are available in single-zone and multizone configurations of up to 8 zones.

In quality and performance, Mitsubishi mini split heat pumps and air conditioners are considered good to premium, comparable to Fujitsu, LG, and Daikin.

The Mitsubishi Hyper-heating H2i and H2i Plus options provide full-capacity heating in subzero temperatures, ideal for northern climates.

Mitsubishi mini split cost begins at around $4,900 for a small single zone system installed. Common systems for 2-4 zones run $7,500 to $11,000 installed. The largest Mitsubishi ductless systems exceed $25,000 when professionally installed.

*And yes, all Mitsubishi systems must be installed by a pro because they need a refrigerant charge, something only a certified installer can do by law.

Let’s get into the details including costs, pros and cons, available systems and options.


Who? METUS stands for Mitsubishi Electric Trane United States.

Mitsubishi ductless systems are produced through a joint venture with Trane Technologies. The 50/50 partnership was established in 2018 to produce ductless systems for both brands. They also make VRF (variable refrigerant flow) systems for commercial buildings.

So, it’s easy to compare Mitsubishi to Trane mini split systems: They are identical in all but the logo.

Mitsubishi Mini Split Reviews

Mitsubishi makes two primary ductless series.

The M-Series is for residential use; the P-Series is a light-commercial line of heat pumps and air conditioners.

The residential M-Series is the focus of this review along with the many indoor unit choices you have.

Single zone systems include one outdoor unit and one indoor unit.

Mitsubishi multi zone systems include one outdoor unit and 2 to 8 indoor units.

First, this Mitsubishi mini split review covers the outdoor units. That discussion is followed by details of your indoor unit options.

Finally, you’ll find pricing and options for both single zone and multizone Mitsubishi mini split systems.

M-Series Outdoor Units

The purpose of this section is to familiarize you with the types of Mitsubishi mini split systems, so you can choose one that is right for your needs and climate.

The goal is to give you a good overview of your choices without burying anyone in a blizzard of model numbers, though there are enough numbers here to assist you in talking with a contractor about your preferences or shopping prices online from sellers carrying some of these Mitsubishi mini splits.

The M-Series outdoor units are manufactured in seven lines:

Single zone or multizone? M-Series systems come in both configurations.

Are winters very cold? You have the high-efficiency/cold-climate H2i Hyper-heating option in both types.

What indoor units do you prefer? There are systems for you whether you are OK with Wall-mounted units only or want options such as Floor, Ceiling, Ducted or central Air Handler equipment.

More details follow, but here is a Mitsubishi mini split comparison chart that serves as a summary:

System Indoor Units Sizes Zones Efficiency
MUZ (-GL, -GS, -WR) Wall Only 9K – 36K BTU 1 16.2 to 24.6 SEER
MUY AC-only Wall Only 9K – 36K BTU 1 16.2 to 24.6 SEER
MUZ Hyper-heat Wall 6K – 18K BTU 1 21.0 to 31.1 SEER
MUFZ Hyper-heat Floor 9K – 18K BTU 1 21.0 to 28.2 SEER
SUZ Universal 8 Choices 9K – 36K BTU 1 15.0 to 20.3 SEER
MXZ-C 8 Choices 20K – 42K BTU 2-8 15.0 to 20.0 SEER
MXZ-SM 8 Choices 36K – 60K BTU 2-8 16.5 to 23.0 SEER

*SEER or seasonal energy efficiency ratio is air conditioning (AC) efficiency. HSPF or heat seasonal performance factor is heating efficiency.

Higher numbers for either rating are more efficient.

Mitsubishi Single Zone Mini Split Systems

Here are the details on popular Mitsubishi single zone ductless systems. Most are compatible with wall-mounted indoor units, but you have options for floor-mounted systems and more with the SUZ universal series.

Single Zone Standard Heat Pumps (MUZ-GL / MUZ-GS / MUZ-WR)

Wall-mounted indoor units only. These are top sellers. Suitable for most homes in cool to hot climates.

Best Use: Any climate but the very coldest. Also, a single zone system is an ideal add-on to a central HVAC system or to an addition to your home, garage conversion, workshop and similar.

Efficiency range: 16.2 to 24.6 SEER / 10.0 to 12.8 HSPF

*9K to 24K BTU units are Energy Star certified.

Sizes: 9,000, 12,000, 15,000, 18,000, 24,000, 30,000 and 36,000 BTU.

Compatible indoor units: Wall Mounted 6K, 9K, 12K, 15K, 18K, 24K, 30K, 36K BTUs.

Pros and Cons: Very good efficiency. Plenty of sizes. The compatible indoor wall mounted evaporators are good, though not the best in terms of features.

Of course, the downsides to all wall-mounted systems is that some homeowners don’t prefer to have units visible on the wall and that the evaporators are not centrally located in the zone.

Single Zone Cooling-only Air Conditioners (MUY)

These units are the same as above, but AC only.

Efficiency range: 16.1 to 24.6 SEER.

Best Use: The MUY series sells well in hot regions of the country, obviously, but they’re also popular anywhere a central cooling system doesn’t do the job in warm parts of a home. Also consider one for a renovated attic or a garage that doubles as a workshop.

Sizes: 7 sizes from 9,000 to 36,000 BTU.

Compatible indoor units: Wall Mounted AC-only 9K, 12K, 15K, 18K, 24K, 30K, 36K BTUs.

*Energy Star: All units up to 24,000 BTU are Energy Star certified.

Pros and Cons: These are affordably priced, mid-range systems with Energy Star efficiency in most sizes. A good range of sizes. But, AC-only, so obviously no heat.

Single Zone H2i Plus Hyper-heating Heat Pumps (MUZ-FS)

*Wall mounted indoor options only.

These Mitsubishi H2i Plus premium-efficiency heat pumps are suitable for very cold climates – delivering 100% of heating capacity at -5F aka 5 degrees below zero. They provide 81% heating capacity at -13F. That’s impressive.

Each size is produced in models with or without base pan heaters to prevent freeze-ups in extreme cold.

Best Use: They are built for climates with extreme cold temperatures – long periods of subfreezing weather with occasional subzero conditions. They are also the choice of homeowners that want the highest efficiency possible whenever heating their homes.

Efficiency range: 21.0 to 31.3 SEER /12.0 to 13.5 HSPF

Sizes: 6,000, 9,000, 12,000, 15,000, 18,000 BTU.

Compatible indoor units: Wall Mounted 6K, 9K, 12K, 15K, 18K BTUs.

*Energy Star – All sizes are certified.

Pros and Cons: These are Mitsubishi’s most efficient units, so electric costs are low. They are expensive, and you might not get great value (upfront cost vs operating costs) in moderate climates. Most compatible indoor types – all wall mounted – have a full range of features including timers, good air filtration and adjustable airflow speed and direction.

Single Zone H2i Heat Pump for Floor Indoor Unit (MUFZ)

*Floor-mounted only.

Best Use: Heating. If you are buying a system primarily for heat, indoor air handlers near the floor make sense. This is because heat rises, so a high wall mounted indoor unit keeps heat near the ceiling unless you also use ceiling fans.

Floor units help maintain a comfortable temperature closer to the floor, chairs, beds – places people are found.

A floor unit also makes sense where usable wall space is limited or when you want a unit on a half wall, sloped wall, or similar construction where a wall mounted unit wouldn’t fit.

Additionally, these are H2i Hyper-heat systems, which are ideal for long, very cold winters. They are Energy Star certified in all sizes.

Efficiency Range: 21.0 to 28.2 SEER / 11.3 to 13.0 HSPF

Sizes: 9,000, 12,000, 15,000 and 18,000 BTU.

Compatible indoor units: Floor Mounted 9K, 12K, 15K, 18K BTUs.

Pros and Cons: Nothing larger than 18K BTU. On the plus side, they fit some spots where a wall unit isn’t practical.

Single Zone Universal Heat Pumps (SUZ)

What’s in a name? In this case, “Universal” means that these Mitsubishi mini split heat pumps are compatible with all Mitsubishi indoor units except for Wall mounted units.

Indoor unit options: Floor, Horizontal low-static ducted, 4-way Ceiling cassette, EZ Fit ceiling cassette and indoor air handler (larger sizes).

Standard and Hyper-heating H2i systems are produced, so you have good options for any climate.

Best Use: If you want to conceal your indoor evaporator in the ceiling or walls or use existing ductwork by installing a Mitsubishi air handler, this system is your only single zone choice.

Need Hyper-heating? You have two options: Standard SUZ heat pumps deliver 75% heating capacity at 5F; SUZ Hyper-heating units provide 100% heating at 5F.

Efficiency Range: Standard – 16.0 to 22.3 SEER / 11.6 to 12.6 HSPF // H2i Hyper-heating – 15.0 to 20.3 SEER / 9.0 to 11.0 HSPF

Sizes – 9,000, 12,000, 15,000, 18,000, 24,000, 30,000 and 36,000 BTU.

Compatible indoor units:

  • Low Static Horizontal Ducted: 9K, 12K, 15K, 18K BTUs
  • 4-Way Ceiling Cassette: 9K, 12K, 15K, 18K BTUs
  • EZ Fit Ceiling Cassette: 9K, 12K, 15K BTUs
  • Multi-position Air Handler: 12K, 18K, 24K, 30K, 36K BTUs

Pros and Cons: You have indoor options including wall-mounted. However, ceiling, and ducted indoor units are often more expensive than wall-mounted evaporators both for the equipment and installation.

Mitsubishi Multi Zone Mini Split Systems

There are two primary choices – Standard and Smart Mitsubishi multizone systems.

Standard Multizone Heat Pump (MXZ-C)

*Multiple indoor unit options. You have your choice of systems with or without H2i high-efficiency performance.

Best Use: When you want a variety of indoor units – or an air handler to work with existing ductwork – then this is a good multizone option.

If your climate has stretches of subzero weather, choose the H2i low-temperature version. They are slightly more efficient in Heat mode, but the major benefit is that they can continue to deliver full heating at a lower outdoor temperature.

Efficiency range: 15.0 to 20.0 SEER / 9.0 to 10.3 HSPF for non-H2i systems // 15 to 18.0 SEER / 9.5 to 11.0 HSPF for H2i systems

Sizes: 20,000, 24,000, 30,000, 36,000 and 42,000 BTU. *The 36K and 42K sizes are not available with H2i Hyper-heating.

Ports: The condensing units come with 2, 3, 4, 5 or 8 ports. Not all ports need to be used on the 8-port units.

Compatible indoor units:

  • Standard / Premier Wall Mounted: 6K, 9K, 12K, 15K, 18K, 24K BTUs
  • Deluxe Wall Mounted: 6K, 9K, 12K, 15K, 18K BTUs
  • Designer Wall Mounted: 9K, 12K, 15K, 18K BTUs
  • Floor Mounted: 9K, 12K, 15K, 18K BTUs
  • 4-way Ceiling Cassette: 9K, 12K, 15K BTUs
  • EZ Fit Ceiling Cassette: 9K, 12K, 18K BTUs
  • Low Static Horizontal Ducted: 9K, 12K, 15K, 18K BTUs
  • Multi-position Air Handler: 12K, 18K, 24K, 30K, 36K BTUs

Pros and Cons: You have a choice of 4 Wall-mounted styles, 2 Ceiling cassette types, Floor units, several Concealed/Ducted types, and the option to use an air handler if you have existing ductwork. If you have existing ductwork but want to switch to a mini split system, these units can give you that when you choose the central air handler option.

Smart Multizone Heat Pumps (MXZ-SM)

These are the premium Mitsubishi multizone mini split systems. You have standard and H2i Hyper-heating choices, though the H2i systems don’t come in 60,000 BTU sizes.

How do these differ from the Standard heat pumps above? Higher efficiency. Quieter operation. They have salt spray protection for coastal climates and are compatible with P-Series commercial systems.

They are similar in that they give you the full range of indoor unit choices plus the option of H2i cold-temperature heating.

Best Use: If higher efficiency is essential, consider this system. Of course, it makes sense in coastal areas too where corrosion and early failure of parts is a hazard.

Efficiency range: 17.8 to 23.0 SEER / 10.7 to 12.5 HSPF in non-H2i systems // 16.5 to 23.0 SEER / 11.0 to 12.5 HSPF in H2i systems.

Sizes: 36,000, 42,000 (H2i only), 48,000 and 60,000 (non-H2i only) BTU.

Compatible indoor units:

  • Standard Wall Mounted 9K, 12K, 15K, 18K, 24K, 30K, 36K BTUs
  • Deluxe Wall Mounted: 6K, 9K, 12K, 15K, 18K BTUs
  • Designer Wall Mounted: 9K, 12K, 15K, 18K BTUs
  • Floor Mounted: 9K, 12K, 15K, 18K BTUs
  • 4-way Ceiling Cassette: 9K, 12K, 15K BTUs
  • EZ Fit Ceiling Cassette: 9K, 12K, 18K BTUs
  • Low Static Horizontal Ducted: 9K, 12K, 15K, 18K BTUs
  • Multi-position Air Handler: 12K, 18K, 24K BTUs

Pros and Cons: You have multiple indoor unit choices. Systems with and without H2i Hyper-heat technology are available.

But with premium quality, efficiency and options comes a higher cost. There are no options under 36,000 BTUs.

Mitsubishi Mini Split Indoor Units

Mitsubishi gives you lots of choice for the Indoor side of the equation.

These units are also called evaporator units and air handlers, though in our discussion, we use the term “air handler” to refer to a central unit connected to ductwork.

Mitsubishi M-Series Wall Mounted

There are three tiers of units: Standard (called Premier in multizone systems), Deluxe and Designer.

Here are your options. Remember to check the information above to see which outdoor units and indoor units are compatible.

Standard Wall Mounted / Premier Wall Mounted

Mitsubishi literature uses both the terms Standard and Premier when discussing these units.

They work with the widest range of outdoor units, both single zone and multizone, and they are Energy Star certified for energy efficiency.

Wall units are a good choice for affordability and good energy efficiency. In fact, they are your only choice in several Mitsubishi mini split series.

Sizes: 9,000 to 36,000 BTU.

Features: Washable nano platinum filter is antibacterial. Smart Set saves your previous settings, so you can return to them with two presses of a button. 12-hour timer. Auto-restart returns the system to previous settings when power comes back on after an outage.

Pros and Cons: Very good efficiency. Good features and a nice range of sizes up to 3 tons / 36,000 BTUs. There is no WiFi option. They are the most affordable choices for Mitsubishi indoor units.

Deluxe Wall Mounted

Deluxe units work with single zone and multizone systems.

These units have most of Mitsubishi’s top features. They are compatible with Mitsubishi’s most efficient mini splits plus you have options for extremely cold conditions – They work with H2i and H2i Plus Hyper-heating systems. You can enjoy full heating capacity down to 5F (H2i) or -5F (H2i Plus).

Sizes: 5 sizes from 6,000 to 18,000 BTUs.

Features: Modes – Your options are Cool (AC), Heat, Dry (dehumidify without cooling) and Auto modes. In Auto mode, the system will choose the right compressor speed and airflow to reach the thermostat setting and keep the temperature there.

Stays cleaner longer. The patented “electric dual barrier coating” is designed to shed dust and dirt so that it doesn’t build up inside the unit, reducing efficiency and performance.

3D i-see Sensor senses movement and locates occupants of the room. Then, you can choose to have airflow directed at you or away from you. When the room is empty, the unit switches to Energy Saving Mode.

Modes are Auto (set your preferences, and the unit will determine which mode is best for meeting them), Heat, Cool, Dry/Dehumidify and Fan-only.

Advanced filtration using nano platinum antibacterial, deodorizing, and electrostatic anti-allergen filters.

Pros and cons: These are the most feature-rich options and support the most efficient and low-temperature outdoor units. As a result, the cost of Mitsubishi Deluxe wall mounted units is higher than the Standard units.

Designer Wall Mounted

The Designer Series EF units only work with multizone systems.

Choose Gloss White, Gloss Black, or Matte Silver in these stylish indoor units. If a wall mounted system is right for you but you prefer better aesthetics, these are your best choice.

Sizes: Four sizes from 9,000 to 18,000 BTU.

Features: The features are similar to the Standard wall mounted units but offer better aesthetics – but only if you want to draw attention to the indoor units. They offer good filtration, auto restart and Economy mode for cooling. A remote is included.

Pros and cons: They are your most stylish option, but again, are only available with multizone Mitsubishi mini split systems. And the capacity is limited to just 18,000, which is right for a zone of up to about 400 square feet.

Designer wall-mounted air handlers cost more than Standard/Premier units too.

Floor Units

Floor-mounted evaporators can be installed directly on the floor or low on a wall. Partially recessed installation is possible to reduce the obstruction into the room.

Homeowners especially like floor units for Heat mode, since heat tends to rise, and these units keep the air warm at “living level.”

Sizes: Four sizes from 9,000 to 18,000 BTU.

Features: Both single zone and multizone floor units are produced. All floor indoor units have H2i Hyper-heating performance for rapid heating in very cold conditions.

You’ll also get a full-feature remote, Energy-saving AC Mode, advanced filtration, Smart Set settings saver, Auto restart after outages, 24-hour, and Weekly timers.

Pros and cons: The floor units include most of Mitsubishi’s most popular features. These models offer versatile installation. The rapid-heating and low-temperature heating are nice features for extreme cold weather.

All sizes are Energy Star certified. Five fan speeds and adjustable directional vanes allow you to control airflow. WiFi is optional.

These units do not include the dual barrier coating which helps internal parts shed dirt and dust, so you might have to remove the cover and clean them more often – every few months.

4-way Ceiling Cassettes

These popular units require recessed installation into the ceiling. They’re typically placed at the center of the ceiling to provide balanced airflow to all parts of the room or zone.

They are sized to fit between joists spaced 24”. As a result, they’re also termed 2’ x 2’ cassettes. Specifically, their size is 22 7/16 square.

Sizes: 4 sizes from 9,000 to 18,000 BTUs.

Features: They can be paired with standard or Hyper-heating outdoor units in condensing unit sizes from 20K to 60K BTUs.

The 3D i-see sensors, 8 of them, detects both the number and location of people in the room and directs airflow accordingly. It can reduce heating or cooling as needed, so the room remains comfortable, and the system is energy efficient.

Airflow can be set to Direct or Indirect depending on whether you want a breeze or wish to avoid drafts. The fan has 5 speed settings.

The system will turn off when the room is unoccupied. You can adjust the off period from 60 to 180 minutes.

You have five controller options for wireless remote and wired thermostats.

Pros and cons: The benefits include great features and wide compatibility with single and multiple zones.

But recessed ceiling cassettes cost more than wall units for both the equipment and installation.

EZ Fit Ceiling Cassettes

These slim-profile units work with most M-Series standard and H2i condensing units. They are ideal for regions with significant air conditioning needs because they are ceiling mounted, and cool air settles in a room.

Unit size is roughly 44” x 14 3/4”. They’re designed for ceilings with joists spaced 16”.

Sizes: 3 sizes – 9K, 12K and 18K BTUs.

Features: Smart Set (remembers previous settings and returns to them next time), Auto restart, low-temperature cooling for computer rooms, 24-hour and 7-day programmable timers.

The vanes can be set to oscillate back and forth plus side to side.

Pros and cons: Excellent feature package. A remote controller is standard, but wall units are optional. WiFi is optional too.

The units include just the standard filter, not the air cleaning or deodorizing filters. An electrostatic anti-allergen filter is an option.

Also, cost to install is higher than installation labor charges for wall-mounted units.

Ducted Units

These units are used in configurations with an indoor air handler. Instead of a duct system as found in standard split HVAC systems, these units use ductwork that runs directly from the air handler to each zone.

These are the most concealed indoor units. Only the air intake and output grille are visible, and they are flush to the ceiling.

Units can be used with standard and H2i condensing units.

Sizes: 4 sizes from 9K to 18K BTUs.

Features: Each has 3 fan speed settings, and the installer chooses one of four static pressure levels to produce optimal airflow.

Pros and cons: Efficiency levels are good at 18.8 to 22.0 SEER and up to 13.1 HSPF heating efficiency.

Up to 3 ducted indoor units can be used in any system – and they can be used in configurations with other indoor unit types such as wall or floor styles.

WiFi is optional. Wireless and wired controllers can be selected.

Because installation is more invasive and requires duct runs, installation costs might be higher than for other types.

Multi-position Air Handlers

Mitsubishi indoor air handlers are similar in function to standard split system air handlers. They can connect to existing ductwork or use individual ducts running to each indoor location.

These air handlers can be configured with Mitsubishi SUZ universal condensing units and most multizone systems.

Sizes: 6 sizes from 12K to 42K BTUs.

Features: The air handlers can be installed for upflow, downflow and horizontal airflow. It uses a standard air filter, similar to those in a furnace or split systems air handler. The units support standard and H2i Hyper heat systems.

Electric heat kits from 3kW to 10kW can be added to the air handler to use as emergency heat if the condenser fails or for additional heating in extreme cold.

Pros and cons: Your system can be configured with just an air handler or with an air handler plus conventional indoor units powered by a single condensing unit outside.

For example, if you have a 48,000 BTU outdoor unit, it can be used with a 24,000 BTU air handler plus a pair of 12,000 BTU wall units. Mitsubishi calls these “hybrid” systems.

All units are Energy Star certified, though efficiency isn’t as high as levels possible with a combination of outdoor unit and wall-mounted indoor unit.


Here are your 3 options.

Base: All Mitsubishi mini split systems have a base warranty of 7 years on the compressor and 5 years on all other parts.

Timely registration: Register your system within 90 days of installation, and the warranty is enhanced to 10 years on the compressor and parts. *California law prohibits requiring warranty registration. All warranty are automatically 10 years in CA.

Diamond Contractor: A Mitsubishi Diamond Contractor is one that has met a range of criteria for Mitsubishi training, customer service and experience. The warranty on most systems is enhanced to 12 years on all parts when installed by a Mitsubishi Diamond Contractor.

This is essentially the exact warranty that Fujitsu offers – a three-tiered system based on timely registration with an upgrade if you choose a brand-certified installer.

How Long Does a Mitsubishi Mini Split Last?

Mitsubishi mini split systems last 15-25 years with 17-20 being average. You’ll get the best longevity from your system with regular cleaning and maintenance by an HVAC technician.

Is Mitsubishi Better than Daikin?

Yes, in terms of highest efficiency. For Mitsubishi, it is 33.1 SEER. The Daikin Atmosphera is a 27 SEER system, Daikin’s most efficient. Mitsubishi and Daikin mini splits are considered premium brands.

One advantage Daikin gives you is the use of R32 refrigerant in some systems. R32 has a lower global warming potential, or GWP, than the R410A used in Mitsubishi systems and most other brands.

Is Mitsubishi Better than Fujitsu?

No. The two brands are very comparable. The top efficiency ratings and the length of the warranties each brand offers are nearly identical.

Choosing a Mitsubishi Mini Split

Here are steps homeowners take when considering the purchase of a ductless or mini split HVAC system.

  1. Zones: Decide whether you need a single zone or multizone system. This is an easy decision for most.

Single zone scenarios:

Converted attics or garages. Additions with just one room, like a bedroom suite, home office or gourmet kitchen. An upper room that is hot in summer and needs extra cooling.

Multizone scenarios:

Anytime you intend to heat and cool more than one room – whole house heating and cooling or a multi room addition.

  1. Climate: Consider your weather throughout the year

The more extreme the weather, the more it makes sense to choose a system with higher Energy Star certified efficiency.

When stretches of weather well below freezing temperatures or even subzero temperatures, then an H2i Hyper-heating system is a cost-effective choice.

In moderate climates, a standard-efficiency system is the best value.

  1. Size the system: It is vital to know the heating and cooling load required for your home. There are DIY sizing apps and online tools. But your most precise load calculations will probably be attained by an experienced mini split specialist.
  2. Get at least 2-3 written estimates from local installers. You can combine step 3 above with this one.

Step 4 gives you the opportunity to compare prices “apples to apples,” but you can compare the costs and benefits of different systems for your home – such as an H2i system vs a standard system.

Mitsubishi Mini Split Return on Investment – ROI

In terms of brand, a Mitsubishi system brings a good return on investment compared to brands considered budget or cheap (MrCool, Pioneer, Blueridge or even Gree).

Mitsubishi is thought of as a good-to-premium brand in the tier with Daikin, LG, Fujitsu, Carrier/Toshiba, and Trane (most consumers don’t realize Mitsubishi and Trane mini splits are identical).

ROI keys are choosing a system right for your climate, having it properly sized and not overspending on indoor units. Let’s take these in order.

Climate: If you spend top-dollar on an H2i or other super-efficient system, but you live in a moderate climate, it will be a waste of money – one you won’t get a good return on.

In terms of sizing, a correctly sized system will make your home comfortable all year. If it’s too large or too small, it will give you hassles while you live there – and might cause issues at sale if the buyer has a knowledgeable home inspector check it out.

Indoor equipment: Standard wall units are the most affordable and bring the best ROI. The more you spend on indoor units, the lower the return on investment.
