This is the reality of living in the UAE, where summer is usually very hot: the climate is characterized by high temperatures ranging from 40 to 48°C (104-118°F). This makes it extremely important for every home to consider installing a good efficient HVAC system. However, with numerous combinations of systems and types in the market today, it may be daunting to make the right decision when selecting an air conditioner. The guide below will help you understand the main aspects to consider when choosing the right air conditioning system to purchase for your home in the UAE by giving you the necessary tips on how to achieve the best ratio of performance and cost in relation to efficiency.

Types of Air Conditioning Systems

Before going deeper into details let us first have a look at some of the categories of air conditioning systems that are present. Each is good in its own way, depending on your home design, your purse and your demands in terms of temperature.

Central Air Conditioning

Central AC systems distribute cool air all over the house via a system of ductwork and vents, knowing the temperature of the house at all times. This is even more beneficial in a large house with many rooms because the system is made in a manner that it will cover a large area well. However, central AC systems cost more in terms of initial installation and these features such as duct-work. They also require constant overhaul to ensure high efficiency in the UAE region where dust is common.

Split Air Conditioners

Picture showing: Central air conditioners are used very rarely in UAE compared to split air conditioners which are very common. These systems consist of two parts: an outdoor unit which consisted of a compressor and an indoor unit which released cooled air. Window ACs are suitable for air conditioning of specific rooms or zones only and are less complicated as compared to central ACs. They come with reasonable energy efficiency and can be bought at much lower prices depending on their size and required capacity, so they can be used both in small apartments and in large houses.

Window Air Conditioners

Window AC units are cheaper than central Air Conditioner and usually an AC unit is installed in a window or a wall of the house. It is portable, easy to fit but the best results it gives is for smaller spaces of a house. They are not as energy-efficient as split or central AC systems but they are very useful for individuals with a limited budget or for the cooling of a particular zone of the house.

Ductless Mini-Split Systems

Like its name suggests, the ductless mini split is a type of split system AC, but it doesn’t use ducts. These systems are suitable for homes that have no ducts or that would need expensive duct systems. The features include; It is highly customizable hence saves energy and has the ability to cool different rooms separately.

Portable Air Conditioners

They can be easily transported from one room to another because of this portability they have. This means that they are very easy to install and do no need to be permanently installed into the systems. Nevertheless, they are not as productive as other types and should be used only occasionally or only for short periods in a hot climate area such as UAE.

Energy Efficiency

Energy efficiency is therefore an important consideration when choosing an air conditioning system in the UAE as temperatures are high more often and the systems used are likely to operate most of the time. This is true, and to be more specific, selecting an energy-saving model can save a lot of money on electricity to be paid every month and help the environment as well.

The better the rating of the system – SEER (Seasonal Energy Efficiency Ratio) the better the systems’ efficiency. The number of SEER represents how efficiently the unit works, therefore the higher the SEER rating, the more money you will save. Inverter technology units are also more energy efficient. Inverter ACs’ compressors operate at variable speeds that depend on the cooling required; therefore, these devices utilize less energy but provide a uniform cool temperature.

In the UAE which experiences very high temperatures energy conservation is not only about how much money you save, but it’s about giving value, cooling output per dollar spent.

Cooling Capacity (BTUs)

Air conditioning power is stated in BTU – British Thermal Unit, which is an indication of the amount of heat and air conditioning unit can remove from a room or house in one hour. There is high importance that you get to select the appropriate size of the AC and that of your space. An overly compact unit will fail to adequately cool the area, while an overly massive one will cool the room quickly, but the air will feel clammy because the room’s moisture has not been adequately removed.

Here’s a rough guideline for room sizes and corresponding BTU requirements:

• 150 - 300 square feet: 5,000 - 7,000 BTUs

• 300 - 450 square feet: 8,000 - 10,000 BTUs

• 450 - 600 square feet: 10,000 - 14,000 BTUs

• 600 -1,000 square feet: 14,000 - 18,000 BTUs

In larger homes or villas which are common in the UAE hail and frosty climate, it may be wise to seek the services of an expert to determine the right BTU for the specific home layout, insulation type and amount of sunlight that the room will be subjected to.

Smart Features and Control Options

Convenience and control are indispensable values for many people in a modern house. Modern air conditioners are designed with smart control options that can make the entire cooling process better and more effective.

• Wi-Fi Connectivity: This feature provides you with an opportunity to operate the air conditioner via a smartphone application. You set the temperature, have control over cooling schedules and even control the energy used from the comfort of your home so that your home is cool when you get in without having to use a lot of energy.

• Programmable Thermostats: A programmable thermostat checks your air conditioner to run at the set times and judiciously turns on or off as set. This can help to reduce lots of energy for example during those times that you are not in the house.

• Sleep Modes and Timers: These options help you maintain a comfortable temperature during the night and save energy by gradually adjusting the temperature or turning the unit off automatically after a certain period.

Noise Levels

Sound produced by an air conditioning unit can become a problem and particularly if it is installed in a room that neighbors bedrooms or living space. While window or even portable air conditioning units tend to be noisy ones, split and ductless mini-split systems tend to be quieter. Exposure to noise is measured in decibels (dB), and quiet-unit ranges between 50-60 dB.

If you prefer your environment especially during night to be free from noise, then ensure that the AC systems have quiet mode or low noise.

Installation and Maintenance

The cost and expenses incurred during installation will, depending on the air conditioning system that is adopted. Central AC systems are relatively more expensive to install and this is because they require duct work more than the split systems which require little or no work and can be installed within a short time only.

With the UAE’s desert climate exposing any building to dust on an almost constant basis, maintenance is crucial for the longevity and performance of your air conditioning equipment. Dynamic objects such as dust and sand by moving into the system can block the passage and hinder the flow of air by blocking the filters and hoods hence requiring more power for the same amount of airflow. Filters should be cleaned or replaced every few months while the entire system should be checked once a year to be certain that it is functioning properly.

Brand and Warranty

For this reason it becomes necessary for anyone in need of an air conditioning system to opt for a reputable brand that offers a sound warranty for the equipment. Some of the top air conditioner manufacturers from different parts of the world include Daikin, LG, Samsung, Gree, Mitsubishi Electric which manufacture efficient air conditioners for the UAE climate.

Ensure that the unit is fully protected by warranty that should include the compressor as well as the other components. It may take between 5 to 10 years on a compressor warranty but on the part and the labor it may be for only one to two years.

Budget and Cost Analysis

Last but not the least; your budget target will define the most suitable air conditioning system for your home. Frankly speaking, it may be quite captivating to have models with extended functionalities, but there are many inexpensive models that provide powerful cooling and, at the same time, do not consume much energy.

Portable air conditioners and Window AC units are clearly the cheapest ones.

Split systems on the other hand are cheaper than the other systems and come with relatively flexible design and great energy factor therefore good for most homes.

While these are more costly than other forms, they may be beneficial particularly if you are using your house for large-family living and do need a consistent cool temperature flow.

Do not be blinded by the mark up price—take into consideration life cycle costs, efficiency, and cost of repairs when devising your choice.

Final thoughts 

Selection of a proper air conditioning system for your home in UAE depends on your specific requirements, energy consumption concern, your pocket and the area of your home to be air-conditioned. Whether you’re choosing a central AC system for big houses or split AC for specific rooms, purchasing a quality, energy-saving air conditioning system will guarantee that your house is comfy all seasons.
