Are you in search of a more efficient, cost-saving and dependable heating and cooling solution for your home? Maybe you’re living in an older home, built before central comfort systems were the norm. Or perhaps you’re thinking about an addition to your house or finishing your basement.

No matter the reason, we’re going to talk about why you should consider ductless heating and cooling.

That’s right! If you think you need to install air ducts as a distribution system to experience efficient, effective heating and cooling in your home, think again. Mitsubishi® Ductless Heating and Cooling systems are excellent for an assortment of applications and their popularity continues to skyrocket.

What precisely do we mean by ductless? True to its name, a ductless system doesn’t involve widespread ductwork to move air throughout a home. Simply stated, a ductless system runs without the use of air ducts. Instead, they depend on a main compressor unit that’s mounted outside the home along with a series of indoor air handlers. Rather than employing a series of ducts, these air handlers are linked to the outdoor unit via a small conduit that extends through the walls.

Each indoor unit can be managed and adjusted to heat or cool a particular area. That’s because air is blown directly into a space instead of being moved through ductwork to reach its destination.

And since a ductless system is devised to transfer outside air to heat or cool a specific space in your home, your HVAC system is much easier to manage, service and maintain.

Ductless HVAC systems keep your home at a steady comfort level, deliver cleaner air and can cut your energy costs by as much as 50 percent. Plus, they are an efficient way to expand your comfort level, no matter the challenges your space presents.

Okay, you’re going to need to have your ductless system serviced at times. After all, what HVAC system doesn’t? In most instances, however, routine maintenance is no more than keeping indoor filters and outdoor coils clean and these tasks can normally be completed by the homeowner. 

Note: You might hear ductless systems referred to as mini-split, multi-split or variable refrigerant flow (VRF) heat pumps or air conditioning systems.


    • Ductless systems provide an excellent heating and cooling answer for older homes that were not built with ductwork. Even difficult-to-maintain rooms are controlled with a multiunit system, as each area includes its own control unit.
    • For empty nesters who don’t intend to heat or cool rooms no longer in use, you might be enticed to close the HVAC vents in those vacant rooms. But this can result in pressure imbalances and even mold problems. It’s far better to install a ductless system in, for example, the master bedroom and set the home’s central thermostat to run at a minimal level.
  • Ductless systems only use as much energy as required to heat or cool a specific space, making them far more energy efficient than most other types of traditional heating and cooling systems.
  • A ductless system is also a cost-effective technique to deliver comfort to a room that you may have not been using due to its being too hot or too cold.

Mitsubishi® ductless systems are the perfect solution for sunrooms, guest rooms, workshops, nurseries, artist studios, garages, basements, home offices, even “man caves.”

Oh, about that new addition! Expanding your ducted system often includes lowering ceilings or otherwise taking away space. Ductless systems are the easy choice to do away with this step of construction when adding a new room. Rather than expanding the home’s current ductwork or pipes or adding inefficient electric heaters or portable air conditioners, opting for a ductless system can supply heating or cooling at a lesser operating cost.

Going ductless is also the perfect upgrade to inefficient baseboard heaters and loud, view-obstructing air conditioners. Rather than expanding your home’s current ductwork or adding electrical heaters, a ductless system delivers economical heating and cooling that’s also much quicker and less costly to install.


That’s right, with a ductless system, you no longer have to depend on space-eating window air conditioning units for your summer cooling. Not only are these window units unattractive and underpowered, but they can also make your home less safe.

Bottom line: Ductless systems not only rid of bulky and difficult-to-install ducts, but they also deliver cost savings and flexibility that a traditional HVAC system simply cannot offer.

HVAC Fact: Did you know that ductless systems have been around the U.S. since the 1970s? It’s also a principal system employed throughout homes in Europe and Asia because of their efficiency.


Quick, easy installation saves time, money . . . often, in just one day.

Ducted systems can often take several weeks to install, they disrupt everyday life in the home and can take up precious space with their size. 

Due to their simplicity, ductless systems provide easier, faster installation in nearly all homes. Let’s face it. It’s far simpler to fish a narrow bundle of insulated refrigerant lines throughout a house than to retrofit cumbersome HVAC ducts. No pricey or invasive ductwork is needed and there is only one small disruption to the property. The outdoor unit is positioned beside your home and small piping running to the indoor unit(s) involves no more than a three-inch hole in the wall. 

Bear in mind, your Schultheis Brothers’ team is trained and highly experienced in the installation of Mitsubishi® ductless heating systems.


Ductless heating and cooling systems provide an array of custom options. 

For instance, many homeowners prefer separate areas of their home to have different temperatures, a scheme identified as heating and cooling zones. Each of these zones will contain its own thermostat, so you only need to heat or cool the space when it’s occupied.

You can also maintain the rooms you mostly live in at specific temperatures for comfort. Keep the kitchen a bit cooler than the rest of the house or maintain the garage at a comfy temperature even in the winter. It’s your choice. 

Even difficult-to-maintain rooms are easily managed with a multi-unit system. It bears repeating that each space has its own control unit. You can also better heat or cool spaces where a duct system just can’t reach or work quickly enough.

Moreover, these indoor units can be mounted on a wall, floor-mounted or installed as ceiling cassettes. Such wall units are offered in a variety of sizes best suited to how you use the room, as well as being provided in an assortment of colors to blend with your furnishings. Most indoor units have a profile of roughly seven inches deep and normally come with sleek, modern looking covers to fit nearly any interior décor.

Keep in mind, too, that ductless systems are not just for a single room. Depending on the model, the outdoor unit can deliver heat and cooling for up to eight different zones or rooms in your home.

You can even manage your home’s heating and cooling from the palm of your hand. Comfort is more than controlling the temperature. It’s being able to do it effortlessly. Wireless remote control is just another option allowing ductless systems to offer personal comfort from every angle.

Plus, for smartphone users, as the saying goes, “There’s an app for that.” In this case, the app gives you total control over your home’s heating and cooling no matter where you are.

One more thing – most ductless systems are intended to keep a room cool in temperatures up to 115 degrees F. and warm in temperatures as low as -15 degrees F. So, while your neighbors down the street might be sitting wrapped in blankets watching the Steelers play this winter, your living space will remain comfortable throughout the entire game and beyond.

Your Shultheis Brothers professional can help you determine the best location(s) for the indoor unit(s) based on your preference and the layout of your home.


Imagine someone whispering to you standing five feet away – that’s how quietly a ductless system operates. It’s heating and cooling that’s truly ultra-quiet.


As we’ve described, in a conventional heating and cooling system, conditioned air is moved through your home via a system of ductwork, found throughout the home, including in the crawlspace, attic and walls.

Often, aluminum tape is applied to seal any seams in the ductwork, while insulation separates the ducting from areas such as in your attic. If this isn’t installed properly, however, there will be air leaks leading to an inefficiency, eventually costing you added dollars. The U.S. Department of Energy calculates that “duct losses account for more than 30 percent of energy consumption for space conditioning.”

Again, no ducts, no worries! There’s no such energy loss because the system doesn’t use ductwork. Having no ducts also means that the entire system doesn’t have to start up each time you switch the system on and off.

Ductless systems are also much smaller, which means less power usage. In addition, the temperature-controlled air of a ductless system is delivered directly into a room instead of an entire home. This means you don’t have to heat or cool a room that isn’t occupied.

Simply put, modern ductless systems are designed to provide the best energy efficiency available today.


As a traditional heating and cooling system moves air from the outdoors through ductwork, it’s also deploying dirt, dust and dander into the home. This debris as well as pesky allergens can reduce your indoor air quality, increasing the risk of allergy symptoms and possibly leading to some serious health concerns for allergy sufferers.

Filters in ductwork are usually installed to catch this debris and allergens, but not always effectively. Moreover, if the filters become jammed up and not routinely switched out, less air will be able to move into the home.

Without adequate airflow, sooner or later, you’ll feel and smell the dust and allergens even more. Also, clogged filters cut the flow of conditioned air into your home, causing the system to struggle trying to heat and cool the home.

With a ductless system, there’s no risk of debris, allergens or other pollutants moving from the outside to the inside of your home.


Ductless systems not only save money, but they also lessen your home’s carbon footprint. 

These systems employ up-to-the-minute improvements in chemical technology, slashing the would-be harmful effects on the environment. Most ductless systems utilize R410A refrigerant, known for its zero-ozone depletion capability, which simply means your system will have less impact on the environment.


Absolutely! Single or multi-zone, heating and cooling or just cooling. Whatever your requirements, whatever you space, however you want to use it, a ductless system provides customizable solutions that are installed trouble-free, conserve energy, are quiet and environmentally friendly.
