Best Air Conditioner Singapore 2016



















Air condition systems are judged by their efficiency in performance, i.e. heating, energy efficiency and cooling efficiency. Here are some of the factors to consider when buying air conditioners in Singapore.

· Maintenance
Air conditioners that work efficiently should have evaporative coolers which keep the aircons dry preventing risk of rusting and causing rust. Filters found in air conditioners require thorough cleaning frequently, depending on how dusty the house is. Failure to clean efficiently will cause the air conditioner to stop working. Also consider air conditioning devices that have condensers which can be cleaned easily by wiping or brushing off so that your house can have undisturbed air flow. Ensure you also pick air conditioning devices that have lonisers which ensure that the air conditioner is always clean by reducing bad odors in the air.

· Inverters
Ensure that your air conditioner has an inverter unit which does not take up high power usage. Most inverters alter the speed of the air conditioner depending on the response to the cooling demand. Some air conditioners have inverters that over speed hence consuming a lot of power. One should also check the energy rating of an air conditioner before purchasing. This is simply because all air conditioners come with an energy rating sticker which uses stars to value their efficiency whereby more stars means that the air conditioner is more efficient.

· Ducted systems
Air conditioners that are ducted are those that are installed in the ceiling or floor. Installing these types of air conditioners can be very costly but they are preferred by many because the whole package comes with a bunch of benefits. Ducted air conditioners have few electronic parts and few risks of developing the refrigerant leakages. However, these systems provide less accurate temperature control.

· Brands
Anyone looking to buy a good air conditioner must consider brands that are most reliable and trusted in the market. Brands such as Daikin, Panasonic and Mitsubishi are generally the most efficient options. The brands mentioned offers easy servicing but may also include additional products of installation; but this does not hinder them from providing the best performance.

· Sensors
The best air conditioners have sensors which have the ability to monitor room temperature whenever there are any changes that require adjustments.

· Timers
Air conditioners that have timers aid in setting the air condition right even when you are not around thus providing a cool environment in the house just before you arrive home.

· Noise
When buying an air conditioner, ensure that it does not have high noise levels which can ruin your sleep or interfere with your working because of the noise.

· Size
Before buying an air conditioner, make sure you consider the size because, using air conditioners that do not fit the capacity of a room is a total waste of electricity. Think about the size of the room you are going to install the aircon before buying it; because getting a size that does not suit the room will require switching the aircon on and off, which is a total waste of time and energy.

What Causes Aircon Light To Blink?
























Aircon light blinking is a common problem in homes that have air conditioners in Singapore. However, if your home is located in a place that has high humidity and temperature you will agree that an air conditioner that is functioning properly is a basic necessity in your home. If the air conditioner malfunctions just for a few minutes, the comfort of your family is disrupted. 

In most cases, an air conditioner will malfunction completely after the light starts to blink. There are cases when the air conditioner even goes off before a technician arrives to fix the problem. 
Fortunately, you can identify the cause of aircon light blinking on your own and then contact a technician with sufficient and accurate information. 

The light of your aircon can blink due to various reasons. Some causes of light blinking are possible to fix on your own while others require help of an experienced HVAC technician. 
Here are some of the causes of aircon light blinking:

· Loose connection: Loose connection in your aircon can cause the light to blink. This can be caused by a tripped circuit breaker. This problem can be solved by replacing the fuse of the breaker and resetting it. Wiring connections can also be loose in the air conditioning unit. You can join such wires on your own but if you do not know how to do it, call a technician immediately.

· Cooling level: Low charge of a refrigerant can cause the light of an aircon to blink. For old air conditioning units, temperatures below 18 degrees can affect the refrigerant negatively. This can cause the light blinking and inadequate cooling.

· Failure to service the condenser: If the condenser is not serviced properly and regularly, air circulation is eventually blocked. This increases power consumption which can cause aircon light blinking. To avoid this, the condenser should be serviced every year.

· Hiring unreliable technician: Unreliable technicians or companies lack the necessary expertise to install and fix problems of aircon units. This implies that when installing or fixing problems of your air conditioner they do not exercise the caution required and this can have disastrous effects on the aircon.

· Poor maintenance: The entire unit needs regular checking and maintenance to enhance its performance. This enables you to detect any fault on time and have it fixed by a reputable technician before it worsens.

· Lack of purifying filters: Purifying filters purify air that gets into your home through the air conditioner. They ensure that your home is always supplied with fresh and healthy air. When filters are not functioning properly or if they are damaged, your aircon light can start to blink.

· Inadequate air circulation: Inadequate air circulation causes ice to form on the windows and doors of your home. This implies that your home will no longer have fresh air.



· Leaking: A leak in the refrigerant can make the aircon light to blink. This problem cannot be solved by adding a refrigerant. Instead, your air conditioner should be checked by an experienced technician who can easily locate the leak. Once identified, the leak can be fixed or another refrigerant added depending on its nature.

· Circuit board problems: A problem in the circuit board can cause blinking of the aircon light. However, such problems are hard to fix and only an experienced technician can fix them properly.
If some of these problems are not fixed on time, they can cause a sudden breakdown of the aircon. Therefore, it is advisable to be keen on the performance and behavior of your air conditioner. If you notice that the light of your air conditioner is blinking, the first thing that you should do is to switch the circuit breaker off and then on after some minutes. The aircon will continue operating normally if the unit does not have a loose connection. 

If it does not operate normally, you should check for loose connections and wire them back if they are there. However, if you do not know how to do it, call a reputable technician immediately. It is important to note that wrong connections can damage the aircon further. 

If you cannot identify the problem using either of the ways, then use a test button of the remote of the air conditioner. This will enable you to determine the error code and then find out what is causing the light to blink on the user manual. This way, you will be able to give the technician accurate and adequate information while hiring them to fix the problem of your aircon

Why Does Air Conditioner Switch On And Off Itself

 In Singapore, having an air conditioner in your office and home is a basic need rather than a want due to the weather which is always humid and hot. Living without an air con will make life unbearable due to the constant perspiring, sweating and general discomfort you will experience from clothes clinging on to the body and many more heat related discomforts. The air con subjects one to enjoying a cool breeze and enjoys some fresh cool air that is not stuffy at all. However, in the course of enjoying your cool sensation the air-con might abruptly switch itself off and then on after a few minutes. This is quite an irritating experience and before concluding on the possible cause of this scenario, you should try establishing the cause of this occurrence before taking it for repair.

          

The action of an air conditioner switching itself on and off can be caused by several factors and thus the need for the actual cause to be established first as it could be as a result of a fault that is simple. One can establish the cause on their own if they understand the various basic parts and components of the air con. The most basic parts include the expansion valve, condensing unit, compressor, evaporating unit and the thermostat.

You can check for the do it yourself (DIY) guide online on how to check if any of these components are faulty before calling in a repair guy. This will save you some money as the professional will always charge for the diagnostic services offered. Below are some of the possible causes of the air con switching itself on and off automatically.

Accumulation of Dirt on the compressor
When dirt accumulates on the compressor of your air conditioner in Singapore, it may cause the switching on and off action. The dirt blocks the excess heat generated by the compressor when it operates normally from being ejected into the environment and this could cause the air con to go off momentarily. This action of heat being blocked from being released into the surrounding air causes both its pressure and temperature to rise.

This in turn causes the circuit of the air con to trip leading to the switching off and then on after sometime. This is a protective mechanism to protect the air con parts from damage which can be occasioned by the pressure and temperature rising high. After the compressor cools down, the conditioner reboots and resumes its normal operation.

It is important to check whether the compressor is dirty or not before you eliminate it as the cause of the switching on and off. If this is the root cause of this issue, you should ensure that the compressor is well serviced to eradicate the dirt. You could also do it on your own by taking out the coil and ensure that it is cleaned using running water.


Erratic Settings

It is important to check the settings on the conditioner as sometimes the automatic switching on and off could be as a result of some erratic settings. It is possible that a person could have made these settings when they were in the office or home and then forgot to restore them back to the original settings they found. Before resolving to call in a technician to repair it, you should first of all check the settings to ensure that they are not set to switch off and on after certain duration of time. Regular checking of the settings made on the conditioner could avoid this scenario in time. One sure way of ensuring that there are no instances of erratic settings on your air con is by taking it for servicing regularly as the professional technicians will always check this aspect every time and rectify it in time.

Faulty components
A malfunctioning or faulty air con component could be the cause of the irritating automatic switching on and off of your conditioner. It could be an issue with the thermostat which is the component responsible for regulating and maintaining the temperature felt in a room that the air con operates in. The thermostat functions by sensing whether the temperature in a given room is at its optimum and maintains it that way.

If it senses a change in the room temperature then it prompts the conditioner to either raise or drop the room temperature. If it is faulty, it will sense wrongly and it may thus cause the shutdown of the conditioner leaving the room hot and stuffy much to the discomfort of the occupants in the room. Professional technician ought to be called in to rectify this issue.

Another component that could be faulty and cause this issue is the circuit board which controls the air con fan. If it is faulty then the air con would have high temperatures and pressure leading to it shutting down and rebooting unpredictably. This situation would require the services of a professional repair technician to sort it out well.

Problems with the condenser could also lead to the conditioner switching on and off automatically. The condenser normally cools vapors that come from the compressor, another component of the conditioner. The switching on and off could be as a result of a blocked condenser. The solution to this issue is to ensure that the debris blocking the condenser is removed and its fins and coils are cleaned.
All the above factors are possible causes of the automatic switching on and off of your air conditioner in Singapore.

They are possible explanations of the query why air conditioners behave in this way. It is advisable to first of all establish the actual cause that could be making your conditioner to behave in the way it does before calling in the repair professionals. Frequent servicing and regular cleaning of the crucial components like the compressor and condenser could also help a big deal in ridding off this issue. Ensure that you check your conditioner regularly and also learn of ways to do self-maintenance on it to save on costs and also prevent it from getting permanently damaged which would force you to replace it.

Here are some common factors that can cause the ice formation on your air conditioner unit in your property.



1. Dirty filter
This is the most common factor that can cause ice formation in your aircon unit. When your filter is dirty, it is not able to function normally and effectively. As the result, the cool air is going to be accumulated in the system. When this situation occurs, the ice formation is going to be formed inside your unit. There are many factors that can cause dirty filter. Irregular aircon cleaning is believed to be one of the most common factors that can cause dirty filter.

It is recommended for you to clean your air filter inside the aircon unit regularly. When it is necessary, you can clean this filter at least once a month. Regular filter cleaning procedure can help you reduce the risk of ice formation inside your air conditioner unit. If your filter is damaged, you also need to replace this broken unit with the new one. Replacing your filter can help you improve the overall performance and function of your air conditioner effectively.

2. Insufficient amount of refrigerant
When you have ice formation in your unit, you should take a look at the refrigerant level in your air conditioner. This ingredient is very important to control the temperature inside your air conditioner. When your aircon unit doesn't have enough refrigerant, it is going to have unstable temperature inside this unit. This unstable temperature is going to form ice regularly. When the refrigerant is very low, the cold coil inside your aircon is going to produce ice.

If you want to solve this problem, you need to check the refrigerant level regularly. Make sure that your air conditioner has enough refrigerant, in order to avoid getting any problems in the future. Don't forget to fill your air conditioner with the right refrigerant solution, especially when your unit is running out of the refrigerant solution.

3. Humid weather
This is another common factor that can form ice on your air conditioner. Humid weather can convert water vapour into fluid on the surface of your aircon unit. This fluid is going to be accumulated in the drip pan of your unit. Because of this reason, this situation is going to accelerate the ice formation on the surface of your unit.

When you feel that the humidity level in your room is increasing, you can start turning on your dehumidifier unit. This unit is very useful to dry up humid air inside your property effectively.

7 Ways You Can Finally Stop Leaking Aircon

One of the electronic devices that is becoming overly important in many homes in Singapore is an air con. They tend to be helpful when they are regulating the level of heat in the house. Nevertheless, like any other electronic device, the air con will most likely have some faults. You may have an air conditioner that is leaking. This can be as a result of many things.

Usually, if the drainage pipe is blocked by some dirt, it will not be able to drain out the water, which in turn will cause the system to start leaking. Also, it could be as a result of poor installation of the air con, especially when it is handled by a non-professional. The system can also start leaking if there is a refrigerant absence. Here are some of the way you can stop your air conditioner from leaking. One thing you should remember is that you must switch off the system when you are attempting these remedies.

       


1. Clean The Blocked Filters 
Suppose the filter of your AC is blocked, mostly due to the dirt piling up, it will mean that the air flow is restricted. For that reason, the temperature of the coil may drop, which will result to moisture in in the filter. The moisture will then condense on the coil and it will finally freeze, thereby, forming some ice flakes. The ice flakes will be blown out of the system, which will come out as a water leakage, dripping out of the system. 

To fix this, you will be needed to check if the filters are dirty and in case they are, you will be needed to clean them with a hosepipe or a shower head. Make sure that you have removed every dirt that has accumulated in the filter, then you can use an antiseptic spray to kill any possible bacteria and mold. 

You might want to check the aluminum coil that is mostly located behind the filters of the air con. Suppose the coil is covered with dry lint, you may vacuum it with the brush attachment of the vacuum. If the coil is extra dirty, a garden spray bottle and a strong grease can help to clean it. Use the grease to spray along the coil and allow it to stay for about 5 minutes, then rinse it with the spray bottle. This will help to enhance the air flow in the system and it will also get rid of any possible dirt in the system. Before cleaning the system, ensure that you have read the manufacturer’s instructions carefully. 

2. Diagnose A Blocked Drain
Normally, if the drain of the system is blocked, water will leak from the system via the air outlets. This will mostly flow on the front part of the air con. You will need to check if the plastic tray is overflowing. The plastic tray is basically meant to trap all the condensate that is given out when the system has been set to a cooling mode. The only thing to do here is to drain the water, in order to clear the drain and avoid further blockage.

3. Set The Heat Pump To The Lowest Setting
This will help to diagnose the insufficient refrigerants. Usually, suppose the air filters and the heat exchange are clear enough and air is flowing swiftly, then the system will be able to give out enough cool air in the room. Nevertheless, suppose there is a shortage of the refrigerant, the system will not cool the room swiftly and water will start leaking from the air con. 

To correct this, you will need to adjust the setting of the heat-pump. The heat-pump should be set to the lowest setting, then it should be left for some minutes. After that, you can check the coil for exchanging heat, which is mostly located under the filter. If it is covered with ice, then you will know that the system has a fault and it will need enough refrigerant to enhance the cooling process.

4. Follow The Right Installation Method 
Lack of proper installation is one of the challenges that causes the air con to leak. Basically, if you have a window air air con, you should install it in a slanting angle, with the rear being partially lower. Doing this will help to allow the water to drain easily to the drain that is at the back of the system. This is a step that will help to avoid any possible leaking. Generally, you must ensure that you understand the right and recommended way of installing an AC.

5. Control The Temperature 
When you have an outside temperature being lower than the inner temperature, the air con might start to leak. This is mostly when there is a humid climate. Suppose the outside temperature is lower than 15C, the system may be filled with ice at night. The ice will melt the next morning and it will start leaking out of the system. You can fix this by switching the system overnight, then switch it back on the following day. Also, you may set the system to Fan Only at night, which can avoid the leakage. 

6. Prevent The Air Leakage 
Suppose warm air that is coming from the outside can get around the AC, the system will be surrounded by cooler air that is also dry. As the warm and cool air meets, condensation will take place. Suppose water is coming out of the system from the front area, you will need to check where the water is coming from. You can add a foam insulation to the system to prevent the warm air from getting through the system. 

7. Call A Professional 
One of the surest things to do in order to completely stop a leaking air con is to call a professional to fix the problem. The technician will be able to inspect the system and resolve where the leak is coming from. This will be easier since they will have the technical know how of how to diagnose and fix the fault with your system.

You can easily fix a leaking air con, but relying on a professional technician can help to ensure that the system is fixed as expected and that it any possible accidents are avoided.

What Causes Aircon Hissing Sound And How To Solve It


A hissing sound is usually indicative of a mechanical issue with the internal working of the aircon. Any mechanical issues with this device should never be ignored. This is because the aircon, or air conditioner, has become an integral part of any home especially now when most people are aware of the impact of air quality on long term health. The presence of harmful particulates in the air that people breathe has been linked to countless respiratory complications and even to some forms of cancer. This is why even if the air conditioner ensures that the air people breathe is ideal and clean, it is important not to forget that mechanical issues with the aircon can end up hurting peoples health not only directly, but also adversely.



 
Hissing as an auditory cue

The necessity of knowing how to detect and correctly diagnose the signs that indicate mechanical trouble in an aircon cannot be better emphasized when the above factors are considered. In order to acquire this vital knowledge, one has to first be in a position to identify the visible and auditory cues indicative of mechanical trouble. The most common and most notable auditory cue is the hissing that is often heard from the aircon unit. It is important to note that this hissing sound does have different levels of intensity. High intensity hissing is usually an indicative of a greater extent of mechanical damage to the aircon, with low intensity hissing indicating lesser damage. However, this need not be the case always as is demonstrated below.

Causes of aircon hissing sound

Any possible number of aircon components can end up being the culprits behind the hissing sound. These components include the following:

1. The aircon’s compressor

The aircon has a compressor whose function is to turn the low pressure refrigerating gas from the evaporator, inside a room, into a high pressure gas that then flows to the condenser located on the outside. The compressor is composed of a powerful motor that is able to force refrigerant into a thick-walled metallic chamber. More and more air molecules are forced into the chamber, which forces the refrigerant molecules closer together causing a rise in the temperature of the gas. This chamber is designed to withstand high amounts of pressure and temperature. However, with the passage of time, these walls can fail and crack. 

When the air inside the chamber is compressed beyond a certain pressure level, the temperature inside the chamber rises causing the crack on the walls to widen. The widened crack then lets the compressed gas to then leaks through the wall. This leak is what is responsible for the hissing sound. The high intensity hiss from the compressor is typically heard a few minutes after the compressor comes on. The hissing sound will be heard from the air conditioner unit located outside the building.

2. Refrigerant lines

The pipes through which the aircon's refrigerating fluid flows are referred to as the refrigerant lines. The fluid flowing through the lines from the condenser to the evaporator is usually in the high pressure liquid form. This line thus bears the highest pressure and is therefore the one with the highest probability of producing a leak. The pipe does eventually crack allowing the refrigerant under high pressure to escape thereby producing the hissing sound. This hiss is usually a low intensity continuous sound that is heard from one of the visible lines moving into the house from the condenser located outdoors.

3. Expansion valve

Compressed high pressure, high temperature gas from the compressor flows to the condenser where it is cooled to a high pressure low temperature liquid. The liquid then flows to the evaporator located inside the house. In order for the liquid to effectively cool the warm air going into the evaporator, it must be first converted into low pressure gas. For this to happen the high-pressure, low-temperature liquid has to pass through an expansion valve. It is at the expansion valve where the transition from liquid to gas takes place. This transition results in extremes of pressure across the valve which over time can cause the valve to fail. The failure is usually evident on the high pressure side of the valve. The result is a high intensity intermittent hiss that is usually heard a few minutes after the compressor powers up.

4. Condenser and evaporator coils

The final candidates for hissing noise that might be heard from an aircon unit are the condensation and evaporator coils themselves. The condenser coil located on the outside of the home is the coil with the higher probability of developing a leak. This is because refrigerant enters and leaves this coil at high pressure. The evaporator coil can also develop a hiss after a prolonged service life. It is however a lot more difficult to detect a leak from the two coils as this tends to be masked by the humming of the fans. These fans are responsible for air circulation across the coils. The hissing from the condenser coil is however more detectable due to its higher intensity.

5. The solution to the hissing from the aircon

In all scenarios it is not advisable for just anyone to try and stop the hissing from the aircon. The first reason revolves around the nature of the refrigerant. The chlorofluorocarbons that were initially used as refrigerants were phased out due to their link to ozone layer depletion. However the refrigerants currently in use do possess a certain extent for poisoning when inhaled. These refrigerants include sulphur dioxide, ammonia and gaseous alkanes such as propane and butane.

A person is required be in the possession of specialized equipment in order to handle an aircon. This equipment prevents of the potentially poisonous gaseous chemicals from escaping into the atmosphere. The second reason arises from the fact that the refrigerant is usually under high pressure and is either extremely cold or hot. This in itself is adequate to cause substantial bodily harm. It is therefore more prudent to seek the services of a qualified air conditioning technician when a hissing sound is heard from the aircon, than to try to resolve the issue by oneself.
