If you’re reading this article, you’re curious about Zoned Comfort Solutions™ – what they are, what they include and ultimately what they cost. Responses to each question are in this article, so let’s dig in.

Mitsubishi Electric Cooling & Heating (Mitsubishi Electric)’s ductless systems or Zoned Comfort Solutions™ are comprised of an outdoor unit connected by refrigerant piping to one or more indoor units. Indoor units come in a variety of styles, and can be networked together to create multiple zones – each controlled separately. A single outdoor unit can create one large zone, eight zones or anything in between. Likewise, a system can include ducted indoor units, ductless indoor units or a mix. What you want for your home determines how your system is configured (and how much it costs).

Zoned Comfort Solutions are sophisticated HVAC (heating, ventilating and air conditioning) systems available for use in almost all U.S. climates. These are definitely not your run-of-the-mill central systems that force you to have one thermostat for an entire floor or entire home. Zoned Comfort Solutions provide individualized zone control, allowing you to save energy and money by more efficiently controlling energy usage, while offering personalized comfort in each space of your home you want to cool or heat.


Millions of homeowners worldwide have already purchased Zoned Comfort Solutions from a Mitsubishi Electric contractor and everyone has their own reason for doing so. For most people, there’s an interest in three key benefits:

1. Zoning. When you work with your HVAC contractor to design your home’s system, you’ll decide how many rooms you want to set up as zones. Maybe you live in a so-called tiny house and want just one zone for the whole place. Maybe you have a larger home and want one zone for you, one for each of your kids’ rooms and a couple for the common spaces. By working with a trained contractor, you can vary the number and location of zones to meet your specific needs. This ability to personalize your comfort – to create specific zones based on usage and to operate those zones independently – is a big draw with this technology. This means your den and its frequently used treadmill can be set to 70 degrees Fahrenheit while your newborn baby’s room right next door can be set to 75 degrees . . . all while your unused guest room can be shut off entirely so you save energy.

2. Quiet operation. With a central system, you experience the whoosh and whistle of air moving through ductwork, the vibration of the indoor unit and the rumble of the system constantly starting and stopping. This is due to a combination of issues all stemming from the outdoor unit’s design and performance, including: a large fan with spinning metal blades creating noise; the fan and fan motor are loud; the compressor sits exposed in the unit compartment and vibrates, causing noise; and the whole unit bangs on and off.

In contrast, Zoned Comfort Solutions’ outdoor units are specially engineered and manufactured for quiet operation. The high-efficiency DC motors and the plastic fan blades are designed to minimize the dreaded chopping sound that many central systems make. The compressor is also housed in its own insulated compartment and sits on rubber feet for maximum vibration dampening. Because the compressor is INVERTER-driven, it typically runs at a low frequency to maintain the desired set point and only ramps up to rapidly cool or heat a zone. Meanwhile, you will barely notice the unit running, which will bring joy to you – and your neighbors!

Zoned Comfort Solutions’ indoor units are also incredibly quiet. They feature a small, compact footprint and have specially designed fans that deliver powerful and consistent airflow extremely quietly. Ductless and short-run ducted units operate at barely detectable sound levels.

3. Efficient operation. Zoned Comfort Solutions minimize the amount of energy used to maintain your desired indoor temperature. Conventional systems are either on or off – all or nothing, using the maximum amount of energy to cool or heat the entire house. In contrast, Zoned Comfort Solutions divide the capacity by zones, and have compressors that ramp up or down based on the needs of each zone to maintain comfort and conserve energy. Many systems are also ENERGY STAR®(link is external) qualified.

  With so many options available to you, it’s easy to see why Zoned Comfort Solutions are not as straightforward to price as some other cooling and heating systems. This isn’t a window a/c unit you can buy online and insert into your window. This is a state-of-the-art system that can be configured to your specific needs and installed many different ways. For this reason and others, a Zoned Comfort Solution must be designed and installed by a licensed HVAC contractor trained to design and install this very kind of system.

While there are seemingly countless options for your home’s new Zoned Comfort Solution, it is possible to get a sense of how much you’ll be spending.

  Components contributing to pricing

Visualize painting your home. There are lots of variables: how many rooms you’re painting, how many coats you’re applying, what brand of paint you’re purchasing, who you hire to paint, if you need to patch any walls first and so on. As a result, the cost can vary widely. The same is true for Zoned Comfort Solutions.

The first step to understanding the cost of your home’s new Zoned Comfort Solution is to understand the individual elements that contribute to that cost:

1. New equipment. Each Zoned Comfort Solution includes an outdoor unit, indoor unit(s), controls and parts including the refrigerant lineset, wiring and electrical accessories. The bigger and more complex the system, the more expensive. Conditioning one room or zone comes at a significantly different price than conditioning a home with eight zones. Generally, new equipment comes in at $3,000 to $15,000. Your costs will vary and may be higher or lower than this estimate.

2. Labor. This is what you pay your HVAC contractor to install the system (and remove your old system, as necessary). Contractors’ labor prices vary widely, but expect to spend an amount equal to roughly 30 percent of your equipment cost. Your specific installation cost might be less or more expensive depending on your geographic location and the specific details of your installation.

3. Possible additional costs

  • Electrical. You may need to hire a licensed electrician to install a new 240V outlet, which generally costs $200 to $1,000, but varies based on geographic location and the nature of the work being performed. The price will increase if your home’s electrical panel requires a new 240V circuit. To avoid surprises, securing an estimate before purchasing a new system is always advised.

  • Equipment pad or stand. Creating an even surface underneath the outdoor unit for proper drainage generally costs $50 to $300. Alternatively, units can be mounted on brackets so talk with your contractor about what is the best solution for your new system.

  • Ductless or ducted? Choosing ducted indoor units introduces a price that is difficult to generalize. Some homeowners might be installing ductwork for the first time while others may be repurposing some of their existing ductwork, which adds a level of complexity – adding potentially 75 percent to the labor cost. It’s best to talk directly with an HVAC professional familiar with your home for advice and estimates regarding ductwork.

  • Creating an opening in the exterior wall (for the refrigerant lineset) is often something your HVAC contractor can handle and will include in the estimate for your installation. If not, you’ll want to hire a carpenter, likely at $20 to $60 an hour depending on geographic location, level of experience and other factors in your area.

4. Controller options. There are many controller options to choose from with Zoned Comfort Solutions. What you select will affect the cost. Wall-mounted units come standard with a handheld wireless controller; otherwise, factor in $200 to $300 per controller for each zone.

5. Any additional equipment needed for unique situations. Some homes need a little extra something; this is true for older homes, high-performance homes, and homes in cold weather regions where the ambient temperature regularly drops below minus 13 degrees Fahrenheit. These homes often require specialized designs and/or equipment, all of which impacts the cost of the system. Our Hyper-Heating INVERTER® technology is developed to provide comfortable indoor temperatures in extreme cold-climate conditions (as low as minus 13 degrees Fahrenheit) while saving energy and money.

  As you can see, there are a lot of variables that affect the estimated cost of a Zoned Comfort Solution. While it is impossible to get a precise estimate of your costs without consulting a local contractor, there is some third-party data available regarding the low end of the cost range. In July 2016, the Northwest Energy Efficiency Alliance published a study[1] showing that simpler zoned comfort solution installations (defined as having one outdoor unit connected to one indoor unit) range from $3,913 to $4,633. Based on this study as well as our internal data, Mitsubishi Electric estimates that you can expect to pay – on average – between $4,000 and $5,500 for each zone (each area you want to condition). Depending on how you design your system, its total price is likely to fall within a range that averages from $4,000 to $20,000.

Your specific price range is directly impacted by the choices you and your contractor make regarding the number of zones you want to condition, whether to use ductless or ducted indoor units, if you want a standard or premium product, what type of indoor units work best and so on. The range of costs will also be determined by where you live. A licensed electrician in your area might cost more or less than a licensed electrician in another state. As a result, the answer to the question, “How much does a Zoned Comfort Solution cost?” remains a range, and perhaps a larger range than more traditional cooling and heating systems. Nonetheless, millions of homeowners have chosen Zoned Comfort Solutions because of the greater value proposition these systems offer through enhanced performance, individualized control, energy savings, quiet operation and the many other benefits we’ve discussed.
Every home, condominium and townhouse has one. It’s impossible to control. The only thing that is predictable about it is its unpredictability. It feels like it costs more than it’s worth. Most homeowners ban their family members from going near it six months out of the year. What is it? The single room that, no matter how hard you wish, hope and try, is always 10 degrees hotter or 10 degrees colder than the rest of the home.

Are You Able to Use Every Single Room in Your Home?

These “hot spots” and “cold spots” can be extremely frustrating for homeowners. Window air conditioners and space heaters can help, but they also cost a lot of money to operate. As a result, most homeowners shut up those rooms in the heat of summer and cold of winter. Closing off access to a den, rec room or even a bedroom is impractical. It reduces living space and can cause frustration among family members. Thankfully, homeowners need not suffer any longer. Ductless systems can be used to control the temperature of a single room, improving comfort and reducing energy costs. These ductless cooling and heating systems have two main components: an indoor unit that is mounted either on a wall or ceiling and an outdoor unit that houses the condenser. The two components are connected by a small conduit rather than ductwork, and offer cooling and heating in one system, which makes these units easier to install and far more efficient than window ACs or space heaters. Single-room solutions are effective for homes that have:
  • Livable attics or basements
  • Sun rooms that homeowners would like to use as livable space in winter
  • Garages that have been converted to livable space
  • Hot spots and cold spots – rooms that just never feel as comfortable as the rest of the house
  • Guest rooms, rec rooms or other rooms that are only rarely occupied

Turn Your Entire House Into Livable Space

Split-ductless systems are ideal for cooling or heating single rooms that get used, but not all the time. Rather than cranking the thermostat up or down to reach a single room, ductless systems can be used to achieve comfort in those spaces only when they are occupied. If no one is in the room, there is no need to pay to cool or heat that area. If you own a home, you should be able to use each room in that home whenever you want. Shutting off a single room in the winter and summer made sense several decades ago when there was simply no other option. Thanks to home zoning, there is no longer a need to board up livable rooms. Zoned systems provide families with almost unlimited, customizable options that allow them to keep their houses open year-round, without throwing money out the window.

Sept 3   Are you looking for an efficient, low-cost solution to satisfy room temperature troubles? No matter what size space you’re trying to cool or heat, discover energy efficient savings and eco-friendly solutions, while keeping the temperature just right inside your home. Imagine the possibilities with a ductless temperature controlled system.

Where’s All the Money Going?

Central air and other similar ducted systems are catch-all heating solutions that lack the precision and control of their ductless counterparts. When a forced air system works to cool or heat your home, you have little control over where that air goes. This means that vacant rooms are getting the same amount of energy and service as your favorite spots in the house.

It’s wasteful, inefficient and expensive to cool or heat the basement storeroom the same way you cool or heat the kitchen or bedroom. But a ducted system doesn’t allow for that kind of precise control. So the cold or warm air flows throughout your home and you see the results of this inefficiency on your utility bill every month.

How can you target the specific rooms you use the most and divert some of the energy and costs from the ones you don’t?

Where Traditional HVAC Falls Short

There are several ways that traditional systems fall short:

  • Thermostat placement is rarely conducive to providing accurate comfort control in other areas. For example, thermostats can often be found in a home’s master bedroom. When the temperature in that room is adjusted, the children’s room across the hall may not be receiving the comfort that it needs.
  • Ductwork tends to run through uninsulated spaces, which leads to thermal heat loss. If there is a leak in the ductwork, or if flex-ducting is pinched due to improper installation, duct-loss will lead to wasted energy as the system has to compensate for the wasted energy.
  • Lastly, conventional systems use a standard single speed compressor that can only run at full speed. This means that the system works at full capacity until the desired temperature is achieved, then shuts off. As the temperature changes, this cycle repeats and can create uncomfortable drafts and expensive energy spikes.

The Targeted Solution

Would you like to get back in control in less than two days? An easy-to-install ductless system has proven technology that is far more energy efficient than traditional HVAC and up to 40 percent more efficient than window units.

Here’s a how a ducted system works inefficiently; it notices that the temperature is, for example, two degrees higher than what it ought to be. It turns on, works frantically to pump cool air throughout the home and when it senses the temperature has lowered, it shuts off. Gradually, the space warms again.

On the other hand, the Mitsubishi Electric ductless system uses an INVERTER-driven compressor to provide exact control 100 percent of the time. They constantly adjust to even the slightest temperature changes in the room so that it doesn’t fluctuate – and they don’t waste money or energy on the zones where you spend little time.

The ductless unit is installed to deliver room-by-room comfort in the spaces you choose. The majority of your cooling and heating energy (and money) goes where you need it, and not where you don’t. In this way, you get personalized comfort in the rooms you use most. This is known as “zone control”.

Even More Ways to Save

Most ductless systems have earned the ENERGY STAR, which means savings as they operate, as well as applicable ENERGY STAR rebates. Some units are eligible for state or federal tax credits, or local utility discounts. The biggest long-term savings comes from using a system that works efficiently. According to the ENERGY STAR website(link is external), “Replacing your system with an ENERGY STAR certified model could cut your heating and cooling costs by 30 percent.”

Big or small, no matter where you live, outdated technology costs more to operate. Ducted systems work round-the-clock sending cold or warm air to vacant rooms and they also use unnecessary energy as the temperature naturally fluctuates. INVERTER-driven compressors in ductless systems ensure the optimal efficiency of the energy they expend; you save even more by concentrating your temperature control efforts in only the rooms that matter.
