5 Best Ductless Air Conditioners

Is it your intention to buy the best ductless air conditioners on the market? You have now selected the appropriate link.

Some people may think that having to put up with a hot summer is inevitable if they have basements or garage workshops without a central HVAC system.

Older homes without ducting may make residents dread the summer as well.

By using ductless air conditioners to beat the heat, a cheap ductwork conversion can be avoided.

A ductless air conditioner’s air handler is mounted to an interior wall, while the condenser sits outside the home.

Up to 34,000 BTUs (British thermal units) of power may be generated by these strong AC units, which is sufficient to chill a room larger than 1,400 square feet.

Many include heating capabilities as well, which help keep a space warm in the winter and cool in the summer.

Depending on each home’s particular requirements, the finest ductless air conditioner on the market must be chosen.

This guide examines the important elements to consider when choosing one of these cutting-edge pieces of equipment.

A thorough analysis of each product’s features, characteristics, and the best reviews went into selecting the best options.

5 Best Ductless Air Conditioners: Overview

Ductless systems are an effective way to increase your comfort, no matter what obstacles your space presents.

Regardless of whether you reside in a freshly constructed residence or a former residence without ductwork, you are adding a room addition, converting an existing space, or wanting greater year-round climate control over a specific room or area of your home.

In its most basic configuration, a ductless, mini-split system consists of one outdoor unit and one inside unit linked by electrical cable and refrigerant tubing.

Without the use of ductwork, the interior unit, which is frequently wall-mounted, forces warm or cooled air into the living area.

This type of system, known as a single-zone system, is intended to deliver heating and cooling enjoyment to a single area.

One outside unit and up to five internal units are combined in a carrier ductless multi-zone system to offer comfort for the whole house.

Ductless HVAC systems are among the simplest and most adaptable to install.

This is because of the variety of interior unit types available and the fact that installation just necessitates a hole in the wall to accommodate the wiring and refrigerant line.

How Does Ductless Air Conditioner Work?

Before installing a new ductless air conditioner or replacing your existing one, it’s imperative to understand how they work.

Individual room units are linked to an outside compressor by mini-splits, often known as ductless air conditioning systems. The inside unit’s evaporator coils are refrigerant-cooled.

The warm air that escapes from the room is absorbed by the coils. The refrigerant then transfers all of the interior heat to the outer unit.

A mini-split system installs small units immediately in each room that pull in warm air and send it out as cold air, as opposed to a central indoor unit connected by huge lengths of ductwork that distributes warm and cool air back and forth.

Because they require far less invasive installation, look nicer in the area, are more energy-efficient, and operate more quietly than traditional air conditioners, mini-splits are a popular alternative to them.

5 Best Ductless Air Conditioners: Pros And Cons


  • The simplicity of installation is the main benefit of mini-split systems over conventional central air solutions.
  • Integrated zoning gives you complete control over the temperature in each space.
  • Mini-splits use heat pumps to run and may both heat and cool a space.
  • Mini-split systems that save energy don’t lose air through duct leakage. Through ducting, 20 to 30 percent of the electricity is wasted.
  • Instead of turning down the entire system, inverter compressors adapt to the demands of the system.
  • Quiet and unassuming presence in the space.
  • No inside wiring, painting, or repairing.


  • A micro split system may cost more to install than a conventional ducted system, but over time you could save money on utility expenditures.
  • Mini split units are wall mounted and visible within a room, in contrast to a conventional HVAC system. The majority of designs, however, are elegant and pleasing to the sight.
  • Filters for ductless systems must be cleaned once a month to remove dust and debris.
  • To run ductless heat, homeowners in extremely cold areas would require a fuel backup.

Factors To Consider When Choosing A Ductless Air Conditioner

Zones and Space Size

The zone design should be one of your top priorities when looking for a ductless air conditioner.

There are single-zone and multi-zone ductless air conditioning units, sometimes referred to as ductless mini splits. Multi-zone units may chill numerous rooms, whereas single-zone units only cool one.

Up to four interior air handlers can be located in various areas of the house, and multi-zone units feature an outside compressor.

A few multi-zone air conditioners can chill a whole apartment as well as a small house.

Most single-zone units can manage between 500 and 1,400 square feet, while most multi-zone units can handle up to 2,600 square feet.


The power of a ductless air conditioner is measured in BTUs, much like that of window-mounted air conditioners and space heaters. The air conditioner can create more cool air the more BTUs it has.

The square footage of the room, the level of insulation in the house, and even the environment where the property is located all affect how much electricity is needed for a ductless air conditioner.

In general, a ductless air conditioner with an output of 10,000 BTUs is needed to cool a space of around 400 square feet. A unit with an output of 21,000 BTUs is needed to cool a space of about 1,200 square feet.

A ductless mini split’s efficiency also depends on the climate and a house’s energy efficiency.

A home in a hot climate requires an air conditioner with a higher BTU output than a home of a comparable size in a location with warmer summers.

Similar to older homes that could lack these amenities, a ductless air conditioner will more readily cool contemporary homes with energy-efficient windows and insulation.

Filter Specifications

Ductless air conditioners employ filters to shield the mechanical components from debris and blockages, much like a central AC system does.

By removing impurities like pollen and dust, these filters are also excellent at purifying the air in a space.

Most ductless air conditioners include washable filters, in contrast to house HVAC systems that use disposable filters.

Just take out the filter, give it a quick water cleaning, and replace it.

By removing the need to buy replacement filters regularly, which can be expensive, this design helps to decrease costs.

Type of Installation

Installation by a professional is necessary since installing a ductless air conditioner sometimes necessitates challenging procedures like brazing copper connections and wiring high-voltage lines.

Some versions, nevertheless, are intended for do-it-yourselfers.

These ductless micro splits come with comprehensive instructions made especially for do-it-yourself installation, so there are no specialized tools or difficult chores needed.

This can save installation expenses by several hundred dollars.

Depending on the kind of installation, labor charges to install a ductless air conditioner might cost between $300 and $1,000, according to HomeAdvisor.

Energy Rating

A ductless air conditioner’s energy efficiency is expressed in terms of SEER and HSPF. I advise looking for SEER (20 or higher) and HSPF (8 or higher) when it comes to ductless air conditioners that are energy efficient.

Heating Performance

Many ductless air conditioners also operate as heat pumps for central HVAC systems, similar to how many AC units do so.

As a result, they can manage the environment in a house all year, negating the need for separate heating and cooling systems.

Heat-pump technology is used by ductless air conditioners to produce warm air.

The BTU output and the coverage of the chilling function are often mirrored by the heat-pump function.

However, bear in mind that in areas with subzero temperatures, a heat pump might not be sufficient for warming a space.

Sound Level

Ductless air conditioners utilize a condenser to chill the air, much like central air conditioners and window air conditioners do.

At roughly 50 decibels, which is comparable to the sound of a typical conversation, these condensers are very loud.

Noise is normally not an issue with the compressor of either a central AC or ductless air conditioner unit because it is situated on the exterior of the house rather than in the window.

Air handlers in central air conditioning systems and ductless mini splits use fans to transport the cold air produced by the compressor throughout the house.

However, most central air conditioning systems locate their air handlers, which may be rather loud in the attic, which solves the noise problem.

The air handler of a ductless air conditioner is fixed to the wall of the space it is cooling.

A ductless air conditioner utilizes a significantly smaller fan than a central air conditioner air handler since it does not need to circulate air across a house.

The quietest setting for this little fan is roughly 40 decibels, or the volume of a whisper.

Some ductless versions have additional silent settings, which let them function at decibel levels that are as low as 35.


The fact that ductless air conditioning systems are more aesthetically pleasing than window air conditioners is one benefit.

Although window air conditioners are an efficient way to cool a space, their boxy design and placement in a window might be unattractive.

In contrast, ductless mini split air handlers are discretely mounted on the wall close to the ceiling.

They also have simplified designs that make it possible for them to blend in with the space more naturally.

The majority of ductless air conditioners have dimensions of 10 to 12 inches in height, 30 to 40 inches in width, and 6 to 8 inches in depth.

Extraordinary Qualities/Features

Multiple settings on ductless air conditioners make them simpler to use. The unit’s remote control is used in “follow-me” mode to determine the ambient temperature.

Most ductless micro split air conditioners offer 24-hour timers that let you program the unit to turn off after a specific period.

For maximum comfort, the temperature gradually rises while you are sleeping.

For systems that only provide climate control while being used, as in a garage, turbo modes quickly cool or heat an area.

The air handler of the unit may run in whisper-quiet modes, which can lower the noise to as low as 30 decibels.

Frequently Asked Questions

Frequently Asked Questions

1. What are the disadvantages of ductless air conditioning?

The cost of mini splits is by far its biggest drawback. Typically, they cost around what conventional AC systems do. The system must be properly sized. Short-cycling, which wastes energy and makes it difficult to effectively control the temperature or humidity, frequently results from oversized or improperly mounted equipment.

2. How Long Does A Ductless System Last?

A ductless HVAC system can run for 20 years or longer. That’s more years than the typical HVAC system would last. With routine maintenance, the majority of conventional furnaces and central air conditioners last up to 15 years.

3. Can ductless AC be installed in any house?

Yes. This not only creates a variable indoor climate, but it may also raise your heating and cooling bills significantly. It’s time to think about a ductless mini-split system rather than carrying on in this manner. Although any type of house can have these systems installed, the greatest prospects are frequently the older ones.

4. How much electricity does ductless AC use?

The quantity of indoor units you have and are using at the same time is one of several variables that affect this. With a single area micro split, you can anticipate using 500–700 watts of electricity each hour. Multiply this by the number of areas that are currently in use for multi-zone mini splits.

5. How big of a ductless AC do I need?

You must multiply the area’s square footage by 25 to obtain the actual BTU rating. Therefore, if you multiply 1,000 square feet by 25 to get BTUs, you get 25,000 BTUs.

5 Best Ductless Air Conditioners: My Final Thought

Because there are so many options, it could be difficult to find the best ductless air conditioner for you. I suggest deciding on a dependable brand first before considering the features.

A multi-zone design will enable you to control more than one area if you need to cool more than one room. Alternatively, if you simply want to focus on one room, a single-zone model will do.

Once you’ve decided on a single or multiple-zone ductless air conditioner, the strongest model with the highest British Thermal Units (BTU) should be taken into account.

If you’re in charge of a sizable area, live in a hot climate, or have poor insulation in your home, the BTU is especially important.

The higher the BTU, the more energy is required to maintain a constant temperature in response to these larger demands.

After electricity, you should take into account any other factors that are significant to you and will have an impact on your daily life.

To save money over time and keep your house warm in the winter, you could wish to purchase a type that also serves as a heater.

If you wish to reduce evening interruptions, devices with specific sleep modes might be most suited to your lifestyle.
