Air Conditioner (AC) Buying Guide: Everything To Know Before Purchasing AC
Air Conditioner( (AC) is an electronic device that can lower the temperature of a closed space. The first AC was invented in 1902 by a skilled engineer named Willis Haviland Carrier. Willis studied thermodynamic flow mechanics and his invention was based on that principle. You can easily buy an AC from brands like Walton, Samsung, Gree, XIAOMI, Haier, Media, General, etc. If you have wondered; of all the Air conditioners available in the market, which AC is best for you? Our Brief Guide on AC will walk you through all the information you must know before buying an AC.
Why Would You Need an Air Conditioner (AC)?
In Bangladesh, excessive heat during the summer is a major issue. The temperature can go up to 39 degrees Celsius or even higher in rural or urban areas. Air Conditioners (AC) can provide comfort against such terrifying heat. Back in the day, Air Conditioners (AC) used to be very expensive but today we have a wide variety of choices available to suit different budgets and requirements.
An AC works in the same method as a refrigerator. It reduces the temperature with the help of 'refrigerant'. This chemical substance gets vaporized after absorbing some of the room heat, and the rest of the heat is ventilated through the exhaustion panel of the device. In this way, it helps you to get cozy and chilled out in the burning summer atmosphere of our country.
Air conditioners of today also come with many advanced and smart features, like controlling the humidity. Today, you can also get Smart ACs in Bangladesh from globally acclaimed brands such as Samsung and VIOMI by Xiaomi . A Smart AC can communicate with your smart home gadgets and intelligently take care of the room climate using Wi-Fi over your router. You can also turn the AC on or off and adjust AC settings over the internet, using any smart device such as a laptop, mobile phone, or even a smart TV.
The most important factors to consider Before Buying an Air Conditioner (AC)
Are you considering getting an AC? There are a wide number of things to consider. But Only a few actually have importance. Below are the most important factors to keep in consideration before buying your AC.
Types
Air conditioners come in two main types - window AC and split AC. The key difference between them is that the window type is an all-in-one device, while the split type works by using two separate units. One, that stays inside your cooling area and cools your space by blowing cold air into the room. The other part is called the outdoor AC unit, which is responsible for heat exchange. Split-type AC is the most popular type of Air conditioner since these offer the latest technology, pleasant looks, and lower electricity bills. Let’s understand the split AC indoor variants better from below.
Multi-Zone Split
In multi-zone split-type AC, more than two indoor units are paired with a single outdoor unit. Multi-zone split air conditioner allows independent air conditioning of more than one zone, which is an affordable solution for many homes.
Cassette AC
Cassette AC are the ones you have most likely seen in large spaces like office buildings, restaurants, or shops. These AC are used to cool large areas easily since they come with up to four air outlets. You can pair the heat exchanger (outdoor unit) and cooler (indoor unit) by using slim piping or ducted vents. In case the AC installation area comes with a duct system (also called air vents), the cassette is connected to the duct system for complete centralized air conditioning. In this sense, it is also called a central AC or duct-type vent system AC. These are the most efficient way of air cooling for places with large gatherings, such as shopping malls. Remember, to install these ACs, you’ll need to have a dust system facility pre-built at the installation zone.
Floor Standing AC
The only single-unit AC in modern times can be found in floor-standing ACs. Floor stand air conditioners work in a pretty similar way as an air cooler. They stand on the floor and provide rapid cooling for a particular zone. These ACs are made portable with the help of caster wheels under them. Floor-standing AC is used where a permanent AC is not suitable.
Tonnage
When you want to buy an Air Conditioner (AC), the size is the first thing that should be considered. AC size is closely related to the area it can cover. An oversized Air conditioner can cool your room faster but the power consumption will be expensive. In contrast, if the AC coverage of your unit is not enough for the cooling area in consideration, your air conditioner will suffer. So, you will need one that balances both. Usually, an AC’s cooling capacity or AC coverage is measured in Tonnage. Tonnage refers to the cooling capacity of an Air Conditioner (AC). Here, one ton is defined as the amount of heat required to melt a single ton of ice in one day. Depending on the design and type, Air Conditioners (AC) can have various capacities ranging from 1 TON to a massive 5 TON!
It is essential to choose an air conditioner with the right tonnage according to the size of your room. For rooms smaller than 130 square ft. a 1 Ton AC is good enough. However, for a room anywhere around 185 square feet, a 1.5 Ton AC is needed to ensure effective cooling. For a bigger space like a conference hall, the required capacity is 2 to 5 tons.
Aluminum Coil or Copper Coil?
The Compressor Unit of an AC consists of cooling coils. Because of the Thermal conductivity properties, Most manufacturers use Copper coils or Aluminum Coils. ACs with Aluminum coils cost significantly lower but Aluminum Coils do not last long and malfunction after a few years of usage. Although Aluminum Coils reduce the cost significantly, they tend to last way less than Copper coils. On the other hand, Copper coils are less corrosive with a better heat Transfer rate. Even though the Copper cooler coil ACs cost more, they will last a really long time without any major malfunction.
Efficiency and Energy Rating
Energy efficiency rating is one of the most important things of concern when it comes to AC. We all want an AC that ensures maximum cooling with minimum power consumption. Every AC comes with an energy rating applied to them. This rating is set up by the Bureau of Energy Efficiency or BEE. The Efficiency and Energy Rating is usually represented with a label indicating its energy efficiency on a 5-star scale. It is calculated by taking the cooling capacity of the Air Conditioner (AC) and dividing it by the total power consumed. A 5 Star Air Conditioner can save up to 35% of electricity consumed. But usually, a 5-star AC will cost more. The Energy rating is important because it ensures better cooling while lowering electricity bills.
Non-Inverter AC or Inverter AC?
Inverter Air Conditioner (AC) usually means the AC uses an inverter technology that converts DC (Direct Current) power to AC (Alternating Current) power. Regular Non-Inverter Air Conditioner (AC) compressor motors have an on or off switch but Inverter Air Conditioner has a more dynamic switching frequency allowing for the compressor to adjust the tonnage as per your needs. In Non-Inverter ACs, the compressor fan always switches between on and off based on the cooling temperature of the room. In the case of the Inverter AC, the compressor always stays on. After reaching the desired cooling the motor stays running at a minimal speed and maintains the desired temperature.
Because of staying always on, inverter AC motors do not consume a peak level of electricity on startup and shut down like the non-inverter ACs. Inverter air conditioners in turn save a lot of electricity. However, Inverter ACs also cost more than non-inverter variants. In a nutshell, an Inverter AC is power-saving and better than a non-inverter 5-star rated AC of the same specifications.
Other Features To Consider Before the Final Purchase
Apart from the Energy rating, Inversion technology, and coil materials, there are a few other key points, to mind. They are:
Filters
The filters in the Air Conditioner (AC) remove or traps any unwanted particles from the outside air. These particles include substances like dust mites, bacteria, pollen, and other allergens. There are various types of Air conditioner filters available: Anti-bacteria filters, Dust filters, Lead filters, and many more. The filters also avoid dust mites evaporating in the air.
Heaters
Most AC models come with built-in Heaters for cold weather. With just one button press, The AC will convert into a Room Heater.
Auto clean Function
Many Air Conditioner (AC) models have an auto-clean function to clean the mold and bacteria formation on the internal part which affects the cooling functionality and life span. Some newer air conditioner filters can clean up automatically by blowing a burst of air onto the AC filter
Dehumidifier
A dehumidifier removes excess moisture from the room while cooling. A room covered in a high level of moisture causes stickiness and sweating resulting in bacteria growth in the environment. The dehumidifier removes excess moisture to give a cozy, comfortable feeling.
Advanced features
Some Air Conditioners (AC) come with many advanced features Like adjustable timers, auto-detecting sensors, temperature or humidity adjustment, Wi-Fi, Smart Connectivity, and Remote Application Control.
