AC topping explained by local HVAC pro

8 Common Misconceptions About AC Gas Filling & Amp; How often should you do this? Refrigerant gas is essential to the operation of air conditioning systems: without it, air conditioners would simply circulate warm air in the room. That's why, with every regular use and over time, it's important to top up to ensure your air conditioning stays in top condition.

Gas refueling is a process that most air conditioning experts refer to as the Gas Air Conditioning Gasket. . It's such an essential part of ensuring the overall efficiency of an air conditioner that technicians recommend doing it once a year.

In this article, we debunk the myths and misconceptions about refilling the air conditioning and how often you should do it.

8 AC Gas Seasoning Misconceptions Debunked

No. 1 Air Conditioning Gas Seasonings Are Not Necessary

Some people think that since air conditioning machines use an AC system closed loop, the initial air conditioning gas will never need to be replaced. If you are unfamiliar with a closed loop system, it is a control system where output is fed back into the system, as input, to generate even more output. It is a cyclical process that usually does not require external effort.

Over time, some of the metal used to create the air conditioning unit will erode away, due to the formation of formic acid in the unit. This erosion causes the formation of small holes which allow the refrigerant gas to escape.

If you neglect air conditioning maintenance, these holes will only get bigger and sooner or later there will be no coolant left to keep your home cool. At best, you'll end up with an air conditioner blowing the same hot air you're trying to exhaust from outside.

Gas filling of air conditioning no. 2 not part of regular maintenance

This misconception is partly due to the fact that some people do not understand what regular air conditioning maintenance entails. But that was before the internet era. Today, most air conditioning control services are well aware of what regular maintenance entails, as a quick Google search will show what other companies are offering.

In fact, due to the way air conditioners are designed, one of the first things a professional technician does is top up the refrigerant gas. The technician will first examine the unit to determine that there are no leaks. This is done by emptying the system, before replenishing the gas supply. In other words, it's Aircon 101!

#3 It's very easy to do

Contrary to popular belief, air conditioning maintenance is not an easy DIY project.

Although some people with mechanical experience and knowledge may have no idea what they are doing, a professional expert is still needed to ensure that all appropriate safety requirements are met. Plus, there's only a limited amount of maintenance an unskilled person can do before the whole process loses its charm and the nuts and bolts start to go missing!

Air conditioning is made up of different parts. The filter, for example, is relatively easy to reach, so it's technically possible for anyone to clean it. Once the air conditioning is disconnected, you can dust it with a vacuum cleaner and then a little soapy water.

(Important: Be careful when cleaning so as not to distort the original shape of this part.)

In the meantime, the CPU and electrostatic units are a bit more difficult for the Joe to maintain medium. Minor damage to the electrostatic unit can cause the air conditioning to shut down. Checking the tightness of a circuit, as well as the pressure of the refrigerant gas, is a task beyond the reach of most owners of air conditioners. The last thing you want to happen is you do your scheduled maintenance yourself and end up messing something up in the process, or worse, forgetting to check some parts and then resuming use of the machine. air conditioner.

If something goes wrong, you definitely won't like the repair cost!

#4 It doesn't help reduce your energy consumption

The question behind this myth is “how does a well-maintained AC save energy?” ie , what effect will lack of proper air conditioning maintenance have on the energy used It seems like your energy bill should stay the same once the air conditioning is in use whether your gas is low or No. Here's where that myth goes wrong:

When the refrigerant gas runs out, the air conditioning takes much longer to cool a room.

If it used to take 30 minutes for the room temperature to drop to bearable levels and now takes 2 hours, that should be a clear indication that your power consumption is high. Filling with gas means it can cool down again faster, reducing power consumption. The only way to use less energy when the gas level is low is to not turn it on.

However, a low gas level should not cause panic. Hire the services of a professional air conditioning expert and you should be right as the rain!

Keep these points in mind:

Low gas levels are caused by gas leaks that can be easily repaired.

The sooner you discover the leak and the newer your air conditioning, the easier it will be to repair.

#5 The impossibility of refueling gas in the air conditioning is cheap

Do you know the myth of ostriches who bury their heads in the sand hoping that their problems disappear? It does not work with air conditioning. Failing to fill the air conditioner with gas will lead to bigger problems for you and your wallet.

#6 Can be done without professional help

If you have nothing to do with your time, give it a try alone air conditioning maintenance can seem quite tempting because it won't cost you nothing. However, if done without the proper measures, doing it yourself can come at an even higher cost.

Finally, think about your safety. If your air conditioner is placed in an accident-prone area, it may be best to call in the experts. Not only will they have the right equipment to reach these areas safely, but they will also be well trained to deal with situations presenting various risks.

#7 Your air conditioner can work well even without it

As you expect your vehicle to work well without regular maintenance, this misconception is another notorious example of common air conditioning myths we can easily dissipate. Your air conditioner may work just fine for the first few months, but with regular use and lack of maintenance, it will eventually falter and require your full attention or, worse, your wallet.

Unlike vehicles, air conditioning units usually don't have indicator lights that let you know when things are going wrong. You will only notice one day that instead of lowering the temperature of the room, the air conditioning will blow hot air. So schedule a service appointment with your trusted air conditioning expert to avoid unwanted expenses.

#8 Not related to the overall performance of an air conditioner

Air conditioners account for about 40% of total energy consumption in Singapore. Part of the reason that number is so high is that most people only think about maintenance when something goes wrong with their air conditioner.

That is, they wait until the gas levels in their air conditioners get so low that they become energy inefficient. Only then do they contact an air conditioning technician.

This is medicine after death. Air conditioning maintenance should be done as a preventive measure against a shorter lifespan and unwanted expenses.

In terms of performance, it will be impossible not to feel the difference between a well-maintained air conditioner and one that is just waiting.

For example, air conditioners that have not been repaired or used for a long time tend to produce a musty smell from accumulated dust. Performance will be mediocre at best, or at worst it will cause you health problems.

How to check if a top-up of air conditioning gas is necessary and how often should it be done?

1. When the air conditioning no longer blows cold air

When the air conditioning starts to show signs of warm air levels, it's time to consider topping up the air conditioning gas.

To test it further, you can place your hand in front of the vent and examine it closely. If it emits the slightest trace of hot air, you should contact a professional as soon as possible.

2. When water starts leaking from the air conditioner

Water leaks from the air conditioner prevent proper vaping. And the main reasons why vaporization does not take place could be the lack of enough gas to complete the process.

3. Poor overall performance

Air conditioners are made to be heard, not heard. If yours is making noise, there is probably something wrong.

4. Ice deposits on coils

Some problems cannot be detected with the naked eye, such as ice deposits on air conditioning coils.

Without regular maintenance to detect and fix this problem, slightly frozen coils can cause corrosion inside the air conditioning unit. The only way to avoid this is to anticipate it with standard air conditioning service procedures.

5. When the air conditioning turns on and off

If the air conditioning power keeps flashing, it means there is no ghost in your house, you just have need an expert to monitor it.


When the air conditioning runs continuously

The air conditioning is equipped with controllers that test the ambient temperature, thus adjusting its cooling system to save energy. If your air conditioner isn't adjusting because it doesn't think the room is cooling, that's a sign there's a problem. For this, you can check and closely examine the operation of the air conditioning thermostat before concluding that an air conditioning gas recharge is necessary.

7. If recommended by a technician or air conditioning expert

It's a breeze.

If an expert tells you that the A/C gas needs to be filled, they do.

Result? A/C gas refill should be done regularly, along with periodic maintenance, for the following reasons:

Keeps your air conditioner running at maximum energy efficiency

Prevents a flurry of mechanical failures that could occur due to low gas level

Allows the air conditioning to cool the room temperature as it should

Just a 10% drop in gas can lead to a 20% increase in your air bill electricity, so don't delay maintenance.
