Central Air Conditioning Vs. Ductless Mini-Split System

Whether it is summer or winter, you can’t deny that installing an air conditioner in your home or business cranks the quality of living up a few notches. The option of setting the air conditioner so that it turns on 20 minutes before you step inside, is just wonderful. There is nothing like coming in from the stifling summer heat, for instance, into a cool comfortable living room or reception area.

Of course, nowadays there are more sophisticated solutions, but we don’t all have smart homes which can be controlled by smartphone. It will definitely become the standard at some point, but for now most Israeli households are not equipped with smart technology. Those of us who will be looking for an air conditioner will most likely choose a mainstream device.

Essentially, there are two main kinds of air conditioners in Israel: ceiling air conditioners and central air conditioners. Each one has advantages and drawbacks, but there will usually be one which is preferable to the other. Every home and household has different needs, and in order to make a more informed decision, we’ve created this article to addresses the more important factors that need to be taken into account when installing an air conditioner. Even though this article is meant to be as comprehensive and useful as possible, remember that nothing can truly replace a sit-down meeting with a certified professional who can consult on makes and models etc. An air conditioning technician will be able to provide a much more relevant opinion, based on the circumstances and your wants and needs.

What is a Ceiling Air Conditioning?

The successor of the floor air conditioner – which, incidentally, is being manufactured less and less – is the ceiling air conditioner. This AC is comprised of two units. The first one includes the compressor, condenser, and expansion valve, and it is located outside. The second unit is located inside, and it includes the button controls (if any), and the fan. The second unit is the one which is visible, and which has the remote control sensor.

Advantages of the Ceiling Air Conditioning

This is the most widely-used model in the country. It is relatively quiet and small, cheaper to purchase, and it can be installed virtually anywhere. Obviously, the spot where it is installed will affect airflow and room temperature, which is why it is best to install the AC in a way that will enable the openings to operate without any hindrance or issue. A ceiling air conditioner is optimal for small or medium-sized rooms, and is less effective at conditioning larger areas.

Financially, the ceiling unit is more economic. Unlike a central air conditioning unit (which we will address shortly), its goal is to cool or heat a single space. Which means that if there is no one in that space, the unit can be turned off, which saves money in the long run.

Drawbacks of the Ceiling Air Conditioning

Its many significant advantages notwithstanding, there are several disadvantages to the ceiling air conditioner which need to be addressed. First of all, looks and aesthetics. The external unit of a ceiling AC is not the most attractive thing in the world, to say the least. Installing a ceiling unit can potentially harm the looks of your home. This is a serious consideration; not for all of us, but certainly for those who care about how their home looks on the outside.

Temperature changes are also a consideration. Because a ceiling unit is all about heating or cooling a single room, this could lead to temperature changes within different rooms of the same home. If one room is cool, and the other is hot, this could lead to problems.

Installation is another factor. A ceiling air conditioning unit necessitates some space within the room in which it is installed, and outside of said room. If you decide to install several ceiling units in one home, make sure you have enough space inside and outside of each room, and that each designated area possess the means for AC installation (such as an electrical socket).

What is a Central Air Conditioning?

Much like a ceiling AC, central air conditioning systems are also made up of two units. However, the crucial difference between them is that a central air conditioning system has the ability to control the temperature of several rooms simultaneously, and also regulate airflow and temperature in large areas. In a central system, the two units are set-up one next to the other, and are usually placed outside of the house. The air which the central AC provides makes its way through air ducts, and reaches the different rooms with the help of air vents.

Advantages of the Central Air Conditioning

Central air is considered to be the most quiet of all AC systems. It makes use of a single unit to provide air to several locations, and in so doing, it reduces the harm being done to your home’s aesthetics. It is a more advanced, more efficient, and more economical. When used properly, for the job it was made to do, there is no doubt that it’s a great choice.

More advanced models allow control of the AC through WiFi, and have the ability to regulate the temperature of each room separately.

Drawbacks of the Central Air Conditioning

The major disadvantage of central air is its cost. If the decision to go for a ceiling AC is one which you could technically make without consulting with a professional, in the case of central air, it is a must. The cost of an error in the case of a central air system is great. Purchase a central air system only once you have made a clear and calculated decision.

Another drawback is the issue of independence. If a ceiling AC should run into trouble, other ceiling units inside of the home will not be affected, since they are separate units. But when a central air system loses certain abilities or stops functioning altogether, the entire house is left without air conditioning, until the issue is solved.

As with the ceiling AC, installation is a major consideration, sometimes being a disadvantage. More modern homes and buildings are designed with central air in mind, and it is a standard in modern-day construction. In a home which is not set-up to facilitate a central air system, the installation of such a unit carries a lot of expenses. Readying the house and installing the system can cost several thousands of shekels. In some cases, there is even a need to lower the ceilings for the air ducts.

We mentioned that central air can be cheaper to use and economical, and this is true, but there are times when it is liable to waste money and resources. A single person located in a room – in a four or five bedroom home – will cause the entire system to function, for one person in one room.

A central air system is also the kind of AC which demands higher maintenance and regular attention. On the other hand, a ceiling AC also necessitates a check-up, at least once a year.

Which Air Conditioning Do I Choose?

After going over the advantages and disadvantages of both of these systems, the only thing left to do is to choose. This is usually not an easy decision to make, especially since it carries with it expenses, time, and energy. In some cases, it would be cheaper to purchase several ceiling units than to invest in a central air system. In other cases, the ceiling units will simply not cut it, and they will need replacing.

Choosing an air conditioner is not an easy task. Whether it is the system, make, or model – everybody has something to say. It is important to note that this article is not a definitive guide, not by any means. Heating and cooling technologies are a dynamic industry, and it is constantly evolving.

There will always be other factors and options to consider. Another issue could be the presence of babies, small children, or the elderly in the home. Another option could be a combination: central AC in some rooms, ceiling AC in others.

The best thing to do is consult with a certified and experienced AC technician, since he has the knowhow – and more importantly, the authority – to provide an adequate solution for any desire or constraint.


Our modern-day air conditioning units owe their existence to Dr. John Gorrie, who invented an ice-making machine back in the 19th century, and which contributed greatly to the advent of cooling technologies which are currently being used by countless AC systems around the world.

Buying an air conditioner can be a simple process or a harrowing ordeal, but the final result is what counts. You need to be happy with your choice, and feel comfortable with your purchase. Remember that even the best appliance in the world must be tended to and maintained. In order to prevent issues and ensure the continuous optimal operation of your device, you need to take care of it. This means cleaning out filters, adjusting temperature in accordance with the seasons and having a professional inspect your system, at least once a year.
