Fixing A Noisy Cassette Aircon Unit In An Office
Today, aircon units have become a necessity rather than a home appliance for the wealthy. Be it in a residential building, office building, warehouse, or rental unit, cassette-type aircon units are very essential in keeping the environment cool and habitable. In addition, because of different varying needs, there are several air conditioning options that a person can find in the market.
A ceiling cassette aircon unit in an office is indeed a great investment. As opposed to boxed-type aircon units that only offer cooling benefits to a small area, the ceiling aircon unit provides all-around cooling and can be an asset to customer services during business hours. However, as with all gadgets, an aircon unit can also run into various aircon issues from time to time. One of these is that the cassette-type aircon unit might sometimes get noisy.
What are the common types of sound a noisy cassette aircon unit emits and its reasons:
There are many different reasons that your office ceiling aircon unit might emit noises. It might be useful to remember that any sort of noise is the surest sign of a dysfunctional cooling system. Understanding the reasons this happens can go a long way in addressing the aircon issue accordingly.
This happens when the valve is controlling the refrigerant and engaging other electrical parts that are not meant to be engaged. To solve this one might need to dismantle the entire aircon unit and put things back in their proper place.
This means that the aircon unit is expanding or contracting due to temperature changes. The first thing one has to do in this type of aircon issue is to switch off the entire aircon unit. Furthermore, to prevent this from happening again it is a good idea to keep the temperature of the aircon unit at a constant rather than changing it frequently.
This is one of the most common sounds made in a malfunctioning aircon unit. It is because of the change in refrigerant flow and can be fixed by calling a professional aircon service company in charge of the aircon unit.
Here are other problematic aircon unit noises that require immediate attention:
Most aircon units produce a low-level hum, and this can be completely normal. However, if the sound is louder than usual, there’s likely an aircon issue with the fan motor.
The buzz could indicate an electrical discharge from damaged or loose wiring, which poses a significant safety risk and becomes a potential fire hazard. Calling in aid of a professional aircon servicing company and catching the aircon issue early could save on potential repairs down the track.
A high pitched squeal or squeak can be one of the louder noises produced by an aircon unit. The piercing sound can indicate that the blower motor’s belt has slipped and requires adjustment. Most modern aircon units no longer use a belt system, so this aircon issue is exclusive to older systems. And yet contemporary aircon units can also squeal if the bearings on the condenser have worn down from use or if the compressor fails. Both problems need to be addressed by a professional aircon servicing company right away before they cause the motor to fail.
Rattling noises are among the most common undesirable sounds to come from an aircon unit. It’s possible that debris has found its way into the aircon unit only to rattle and annoy. A much more serious cause is that loose parts have broken off and are now rattling around in the ducts or fan.
If the outdoor compressor has experienced damage, then a fan blade may have bent and now brush the sides of the casing. Whatever the cause, there’s potential for the damage to worsen, so call a professional aircon servicing company as soon as possible who may be able to provide a simple solution before a big one or a replacement is required.
Here are a few useful tips that might help you fix your noisy cassette aircon unit:
Disconnect the entire aircon unit:
The first step to fixing a noisy ceiling cassette aircon unit is to disconnect it. This prevents further damage and also keeps a check on the chances of accidents or mishaps. After this one must contact a professional aircon servicing company since this requires expertise and it is an office all-around cooling device, chances are that it will take more than a couple of hours to fix. The sheer size of the aircon unit needs extra technical help and unlike home units that can be fixed using smaller mechanisms such as cooling foams or insulation mats, these types of aircon units need professional help. It is also a good idea to ensure that you keep the warranty card with you in your office in times of emergency.
Warranty period and durability:
The first thing you need to check for is the date of purchase of the aircon unit. While some aircon units can be fixed over time and with added services, many times office owners find that the aircon unit is too old for it to be of any value. In cases such as these, it is better to sell off the entire thing. There are many professional aircon servicing companies in Singapore that will be willing to buy the second-hand aircon unit and you can get some of the investment money back as well.
Routine cleaning and maintenance of the condenser:
The reason many aircon units start to make a whirring noise is because of the dust accumulated in the internal units. One can hire a professional aircon servicing company to clean the condenser regularly. An unmaintained condenser could bring some serious aircon issues that will definitely bleed your pockets. A noisy air conditioner is not only an inconvenience but is also a dangerous problem. This is because it is indicative of the expanding and contracting hardware of the device. In addition, there might be internal aircon issues that are causing inefficient cooling and abnormal noises.
