Ductless Heating & Cooling Options for a Home or Business

Believe it or not one of the most devastating aspects of any commercial or residential HVAC system isn’t the compressor, condenser, blower motor, or any of the other moving parts; it’s the thing that does supposedly nothing – the duct system. Duct systems not only carry allergens, dander, and debris to every room in the house, they are also a huge reason for energy loss simply in the transfer of air, never mind the leaks.

It’s not hard to see why many homes and businesses are researching their options for a ductless HVAC system. Eliminating the path of heated or cooled air from where it is handled to where it is delivered produces fewer allergens while also reducing energy loss. With that said, here are some of the ductless HVAC options available for homes and businesses, whether they are building new or replacing existing components.

Ductless Mini Split

The ductless mini split air conditioners are a trendy choice for both homes and businesses for a number of reasons. First of all, the lack of ducts helps lessen energy loss and creates fewer allergens jostling around the room. Ductless systems contain a compressor/condenser outside the home and copper lines carrying refrigerant to an indoor fan unit. This one-to-one setup proves ideal for cooling home renovation additions without trying to tap into the existing HVAC system or for use in a room that is unreasonably warm (facing the sun) without taxing the entire central air conditioner. With the installation of a heat pump, any ductless A/C systems will also supply warmth, serving as a full HVAC unit.
Single zone ductless systems are available in the most basic form for something like a lake house or rarely occupied room. They are also manufactured in more advanced versions that feature programming, motion sensing, wi-fi automation, and 3D airflow.

Multi-Zone Ductless Split

One hindrance of the single zone system is that the compressor can only cool one fan/vent component and therefore only one room. The easy solution is a more powerful multi-zone ductless system in which 2-4 ‘heads’ can be installed in different zones of the home or business. This proves a more cost-effective solution than running central air in a smaller square-footage home or a part-time residency. Multi-zone units also work great in a small office where multiple rooms may all want to have different temperatures (conference room, cubicles, break rooms, etc.).

Dual Condenser Units

For the most part, the maximum output that any single condenser can supply heating / cooling to is four rooms (or four fan / head units). The solution in larger homes or offices then is to install a second outdoor condenser/compressor unit which increases the output to between 6-8 different rooms. The configuration can be manipulated to the property owners needs whether they want a single control, multi-controls, or have heating and cooling in specified zones.

Installation Types

Another benefit of ductless systems is that the indoor fan units feature multiple mounting options. The fans can be placed on a wall, on the ceiling, recessed in either the wall or ceiling, or with concealed ducts. The temperatures can be controlled with a remote control and rooms are conveniently cooled without having to block the view with a window A/C unit or lose energy through a ducted system.

What Brand

Everyone has different needs and desires. That’s why Connecticut Retrofit does not sell an exclusive brand. At Connecticut Retrofit we install Fujitsu Ductless Systems, Mitsubishi Ductless AC, LG Ductless Systems and

The great thing about these various HVAC systems is that they provide options. Commercial or residential customers are not limited to a ducted air flow system and can instead choose heating and cooling options based on their home layout, health history, budget, and needs.

Ductless Mini Splits: A Maintenance Checklist for Efficiency

When traditional ductwork is not an ideal choice for your home or business, Connecticut Retrofit can install a ductless mini split instead. The advantages of a ductless system include an inexpensive installation and less operational costs when compared to traditional ducted systems, as well as simpler maintenance. Because a ductless mini split is easy to maintain, you can do some of the simple maintenance tasks yourself, without the help of a professional.
Here’s how:

Ductless mini splits mesh filters need to be cleaned once or twice a season depending upon how clogged they become in your location. However, if the ductless mini split is in a laundry area or in a large facility, such as a warehouse, you might need to clean these filters every month.
Remove and clean the indoor quality (IAQ) filtration components after 400 hours of operation (about every two to six months).
Examine the evaporator (indoor cooling) coils annually for debris and clean them biannually. Use a soft-bristled vacuum attachment to clean the coils. If necessary, use a solution of bleach diluted with water to remove grime- often this activity is best left to a trained technician unless you are pretty handy.
Check the drain pan for moisture. To clean the pan, use a diluted bleach solution. If you do find water in the drain pan, often it is a good idea to contact an HVAC technician to inspect the ductless mini split.
Verify that the blower and fan wheel are in balance. If not, contact an HVAC service technician. To clean the fan, use a soft-bristled vacuum attachment for dust and diluted bleach for grime.
Check the condition of the condensing unit (located outside). The interconnecting tubing should not have any bumps, and the insulation should be in good shape. Make sure the unit is still mounted on its base well, and that the base has not moved, gotten out of level or slipped.
Remove any vegetation and clutter from within 18″ of the unit.
While you can perform simple maintenance on a ductless unit by yourself, you should schedule an annual professional inspection of the unit with Connecticut Retrofit. Our Energy Specialists can find and fix problems that you may not notice, thus extending the life of your ductless system. Lack of required maintenance can invalidate manufacturer warranties, so it is always a good idea to schedule annual or semi-annual maintenance for heat pump version of the ductless split system.

How Much Does A Ductless Mini Split System Cost?

Are you looking for a quiet, efficient heating and air conditioning solution for your home, that can severely reduce your energy costs and quickly pay for itself? Then you’ll want to consider a ductless mini-split system from Connecticut Retrofit.

Ductless is a flexible and energy saving alternative to traditional air conditioning systems, window units and oil heat. So, what can a homeowner expect to pay for this modern and convenient home comfort system?
Ductless mini-split’s have been around for more than 50 years now, but have only been available in the U.S. for  over 30 years. 90% of households in China use ductless and 80% in Europe. However, misinformation and other factors have slowed the growth of ductless in the U.S. However, education and high energy savings have the government offering rebated and homeowners taking notice. And, it’s making ductless one of the fastest growing segments of the HVAC industry.

So, how much can you expect to pay to have a ductless system installed in your home. As you can assume, it depends. Installations typically cost anywhere from $2,900 to $20,000. The price of your system is determined by four things:

The size of the unit
• The type of unit
• The number of areas (or zones) being conditioned
• The degree of difficulty of the installation (How far the indoor and outdoor units are from each other, the construction of the outer wall to be drilled to carry the line sets, etc.)

Due to the flexibility of these systems there are multiple configuration possibilities that can slide your job from the lower end of the cost range to the highest. For example, are you trying to cool one room or a whole house? The amount of windows in the room can also be a factor. A ductless system, on its most basic level, consists of:

Single Zone Installation

Professional installation of the most basic, or single zone, configuration (consisting of one wall unit and condenser) will cost around $2,800 to $4000. This layout is perfect for many kinds of applications like cooling or heating the air in a sun room, garage, attic, smaller homes and more.

A single ductless unit could be the perfect option for keeping your sun room comfortable all year long.

Multi-Zone Installation

Some homeowners will have one ductless unit installed in their home, while others install 3-5 units. It really depends on the layout of the home and what works best for the homeowner. A multi-zone system consisting of two indoor evaporator units typically run between $7500 and $8000. Up to four indoor wall units can connect to a single outdoor condenser, so a general principle in calculating the cost of more than one unit is to add $3000-$3500 to the initial $3500-$4000 for up to 4 units. After four, you’ll have to factor in the cost of an additional condenser.

Multi-zone ductless cost and estimates

Initially the cost of ductless heating and air conditioning can seem really high compared to buying a window unit. However, the benefits in energy efficiency will save you a lot in the long run. Since there are no ducts, you won’t lose energy, aka hot air in the winter and cold air in the summer, via duct work. Typical forced air systems experience duct losses equaling about 20% of energy consumption. They’re also less expensive to maintain than traditional systems. And, you can finance the project as well as a lot of rebates from the government and energy providers.

A multi-zone configuration comes with an additional energy saving benefit. The homeowner can control the temperature independently in each room an air handler is installed in. So, if you’re not using a room, you won’t have to keep it heated and cooled like the rest of the house.

Finally, you’ll need a qualified installer, like Connecticut Retrofit. If you’re interested in a ductless system for your home, give CT Retrofit a call at 860.238.3112 or click the button below to schedule an appointment.



Ductless Mini-Splits – Your Highest-Efficiency Heating & Cooling System

A mini-split air conditioning system, also called a ductless mini split system, is a smart alternative for uncomfortable homes where traditional cooling and heating systems aren’t getting the job done.

Traditional approaches to cooling and heating include use of air conditioners, ducted air-based central cooling and heating, hydronic radiators (water-based heating) or electric space heaters.

Ductless minis, on the contrary, are ideal for homes where installing ducts would be expensive or infeasible. They have no ducts, so they avoid the energy losses associated with the ductwork of central-forced air systems. reports that duct losses can account for more than 30% of energy consumption for space conditioning, especially if the ducts are in an unconditioned space, such as an attic.

With a ductless mini split system, its air-source heat pump can run in “reverse,” supplying hot air in the winter and cool air in the summer. If you’ve ever waved your hand over your AC unit outside on a hot day while it’s cooling your house, you probably noticed the outdoor unit was blowing hot air. During cold weather, the heat pump component reverses this cycle to move this heat into the house.

The main advantages of mini split air conditioning systems are their small size and flexibility for zoning or heating and cooling individual rooms. Many models can have as many as four indoor air-handling units (for four zones or rooms, each with its own thermostat) connected to one outdoor unit. The number depends on how much heating or cooling is required for the building or each zone (which, in turn, is affected by how well the building is insulated and air sealed.) A home that includes a mini split system along with proper insulation and air sealing will provide the highest level of comfort.

The hook-up between the outdoor and indoor units generally requires only a three-inch hole through a wall for the conduit. A homeowner can locate the outdoor unit as far away as 50 feet from the indoor evaporator. This makes it possible to cool rooms on the front side of a house, but locate the compressor in a more advantageous or inconspicuous place on the outside of the building.

In comparison to other add-on systems, mini splits offer interior design flexibility. The indoor air handlers can be suspended from a ceiling, mounted flush into a drop ceiling or hung on a wall. Floor-standing models are also available. Most indoor units are about seven inches deep and have sleek, high tech-looking jackets. Many also offer a remote control to make it easier to turn the system on and off when it’s positioned high on a wall or suspended from a ceiling.

With a split system, you no longer have an obstructed view of the outdoors, since your windows are free of cumbersome window-mounted air conditioning units. Split systems can also help keep your home safer, because there is only a small hole in the wall. Traditional through-the-wall and window-mounted room air conditioners can provide easy access for intruders.

Top 5 Questions About Ductless Air Conditioners – Answered!

So, you’re looking to cool a room (or two…or three) in your Connecticut or Rhode Island home, but you don’t want to mess with installing extra ductwork to cool them. Or maybe your home does not have ductwork at all.

You’ve heard of ductless mini-split air conditioners. They sound interesting, but you have lots of questions.

You’re not alone.

Many New England homeowners have questions about ductless mini-splits and ductless ac. We aim to answer the top 5 ones in this article.

“What is a ductless mini-split air conditioner?”

A ductless mini-split AC is just as it sounds: it’s a mini version of a split central air conditioning system. But it does not use ducts to deliver cool air, so it avoids the energy losses from leaky ductwork.

A ductless mini-split air conditioner is made up of 3 main parts:

A condenser unit located outside your home
An evaporator/blower unit located in the room where you need cooling
A conduit that links the outdoor and indoor unit (the conduit houses the power cable, refrigerant tubing, suction tubing and condensate drain)
They’re small, quiet and have several placement options for effectively cooling different rooms in your home.

They also come with a remote control so they’re convenient to use.

“When would I need a ductless mini-split air conditioner?”

Because mini-splits don’t need ducts and therefore require minimal installation, they’re great for adding cooling for:

Home renovations
Home additions
Sun rooms
Zoning (great for homes where the upstairs is unbearably hot during the summer)

“Doesn’t a window air conditioner serve the same purpose as a mini-split air conditioner?”

Yes, in some ways. Both can be used to cool a single room without ductwork.

But a mini-split can add more evaporator units (up to 4) to one condenser unit. So technically it can cool up to 4 rooms. Mini-splits are also much more energy efficient than window units and last longer, too.

A window air conditioner’s main selling point is that it’s relatively cheap. But they can also be a safety hazard since burglars could get into your home by removing the window unit.

Learn more about the pros and cons of a mini-split air conditioner vs. a window unit.

“Is it easy to install a ductless mini split system?”

Yes and no.

It’s not something you want to DIY install.

But it is relatively easy for a qualified, professional contractor to install. The installer will need to determine where to place the inside and outside unit and then drill a 3-inch hole through a wall for the conduit.

And the conduits come in several lengths, so you could easily cool a room in the front side of the home with the inside evaporator unit, while the outside condenser unit remains inconspicuous in the back of your home.

Another reason why you don’t want to DIY is that you’ll need a professional to decide the right size (tons) mini-split you should install:

Too small and the system will struggle to cool the room, increasing your energy bills.
Too large and the system will short cycle, meaning it will cool the home too fast. This wastes energy and won’t properly dehumidify the room.

“How much does a ductless mini-split air conditioner cost?”

The cost depends on several factors, including:

Energy efficiency rating (SEER) chosen
Size (tons) of the system
Number of evaporator/blower units
And then there’s the cost of installation, which depends on what the contractor charges.

But in general, a mini-split will cost $1,500 to $2,000 per ton (12,000 Btu per hour) of cooling capacity, according to the U.S Department of Energy. That’s about 30% more than central AC systems (but that’s not including ductwork). And may cost twice as much as window units of similar capacity.

How Ductless AC Works


There are many ways to configure this modern and versatile system for all your comfort needs. Highly efficient and effective, a ductless system is the ideal primary heating and cooling solution for your home or business in Connecticut.




View Fujitsu Brochure


Ductless splits, also called “Mini-Splits” pump cooled or heated refrigerant directly to the wall or ceiling-mounted air-handling unit, and each unit has its own wireless electronic temperature control system otherwise known as the remote.

Here’s how the system works in a single room

The indoor unit uses refrigerant to cool or heat the air and quietly pushes the cold air where you need it in your living space.
Refrigerant and electrical lines connect the outdoor unit to the indoor unit through a 3″ opening in the exterior wall.
The outdoor unit’s heat pump cools or warms refrigerant and sends it back inside to the air handler, which is always monitoring the room for changes in temperature and sends cool air to the areas of the room that need it.

What’s The Difference Between A Single Zone And A Multi Zone

Single Zone

Perfect for additions, basements, sunrooms or any other space that offers a comfort challenge.

Ductless is a perfect solution for homes with problem rooms that just neverfeel comfortable. You know, a great room with a high ceiling, or large glass exposure. A sun room or addition. Even a converted attic, or a remodeled room over a garage.

Ductless systems allow you to pinpoint the area of your home you want to condition, which always takes some of the load off your existing HVAC system, saving you money.

Multi Zone

Keep all the rooms of a house at maximum, individualized comfort levels without all the ductwork.

With a ductless system it’s easy to select exactly how much you want to cool or heat each room or zone of your home to accommodate your family’s desires and lifestyle.

With a ductless system solution from Connecticut Retrofit, you can eliminate energy use in the rooms you’re not using, or design a climate in your home based on the factors that make you and your home unique.
