Singaporeans have embraced the usage of air conditioners as standard home equipment. It cools the home, allowing us to live in a more pleasant atmosphere during the summer months.

These technologies have become so common that it is virtually hard to envision living without one of these devices. So in every home, you must not overlook the aircon services and maintenance system for it to run smoothly and provide adequate aircon gas on schedule.

As a result, it is important that we routinely top up aircon gas to achieve optimal performance. However, if you’re unsure how frequently you should top up your air conditioner gas, below are some guidelines.


Aircon Gas Top-Up: When You Need It and Misconceptions To Avoid

Paying attention to when your aircon at home or workplace is acting up can prevent many unexpected costly challenges. Best to head these signs:

1. Aircon can’t be turned off

Typically, an air conditioner must operate for a short time and be turned off after the room reaches the desired temperature. However, if we see that our air conditioner continues to run without being able to stop, then it is time to get an aircon repair and troubleshooting service. We must transport it to a service centre for this issue to replenish the air conditioning gas.

2. Odd noises emanate from air conditioning system

An air conditioner that is brand new or has been adequately maintained does not create a lot of noise. Despite this, components begin to wear down and get loose, resulting in noises. Recharging the air conditioning system with high-quality air conditioning gas, such as Freon gas, is an important aspect of appropriate maintenance.

3. Air conditioner cycles turn on and off often

A brand-new and properly functioning air conditioner should be able to run at a set cycle. It should be turned on for the selected time before being turned off again. If this occurs, your aircon unit may need a gas refilled by a reputable air conditioning service company. With EconCool, you can resolve this aircon gas top-up issue promptly.

4. Aircon is unable to create cold air

This is the quickest and most reliable way of determining whether or not the air conditioning gas needs to be recharged. Overall, the gas assists in converting heated air into a more pleasant temperature by cooling it down. That’s the general rule of thumb. Consequently, if our system cannot create cold air, we will surely ensure that the gas is insufficient. Because cold air is distributed evenly throughout the house, it is simple to put our air conditioner together such that it will no longer create cold air. As a result, a high temperature in the home indicates that the gas level has dropped.

5. Water leaking from aircon

This is another great way of determining whether or not we should top up the air conditioning gas. Water leaks in the aircon unit often indicate that a gas top-up is necessary. A water leakage occurs due to insufficient vaporisation activities in the boiler. When the gas is low, the vaporisation process is not completed completely.

However, the leaks may be a result of other factors as well. If this is the case, it is critical to consult with an expert who can diagnose and resolve the problem related to a gas shortage.


The air conditioning system’s operation depends on refrigerant gas — your air conditioner will only circulate hot air in the room if you don’t have it. So to keep the air conditioner in good working order, it must be filled every time it is used regularly and over time.

Most air conditioning specialists use aircon gas top-up to describe the process of gas replenishing. This is integral to maintaining the air conditioner’s overall performance, and the technician suggests doing it once a year.

Top 3 Misconceptions About Aircon Gas Top-Up

As the best aircon servicing company in Singapore, our fair share of experience in the field has allowed us to often hear our customers complaining and gullibly believing what their neighbours, aunts, uncles, parents, etc. have been telling them.

So after gathering some of the most common ones we hear our customers say about aircon gas top-up, we hope this can serve as a lesson for you always to be better; do better.

  • You don’t need to add gas to your air conditioner

Some think the original air conditioning gas doesn’t need to be changed because the air conditioner has a closed-loop system. The output is fed back into the closed-loop system to make more output. This is a recurring process that requires no outside help.

Some of the metals used to make air-conditioning equipment will rust over time because of the build-up of formic acid, which can cause small holes to form, letting refrigerant gas out.

If you don’t take care of your air conditioner, the holes will get bigger and bigger, and soon there will be no coolant to keep your home cool.

  • ANYONE can do aircon gas top-up

Contrary to people’s belief, air conditioner maintenance isn’t a simple DIY project. Even though some people with mechanical experience and knowledge might not know what they’re doing, a professional expert is still needed to ensure that all safety rules are met.

Parts of an air conditioner, for example, the filter, are easily accessible and can be cleaned by anybody. After disconnecting the air conditioner, clean it with a vacuum and soapy water. (Be cautious while cleaning not to alter the part’s original form.)

The central and electrostatic components are more difficult to maintain. Any damage to the electrostatic unit might disable the air conditioner. Most air conditioner owners can’t check a circuit’s tightness or the gas coolant’s pressure. The last thing you want to do is DIY your planned maintenance, ruin something, or worse, and restart your air conditioner.

  • Save more money on electricity bills when aircon gas is low

When it comes to air conditioning, many people feel that their energy costs should be the same once they start using it, no matter how low their gas is.

If your refrigerant gas level is low, your air conditioner will take longer to cool your space. In other words, if your room temperature was formerly bearable for 30 minutes, but now it takes two hours, this is a vital sign of excessive energy usage in your home.

Filling up the gas implies that the unit may cool down more quickly, lowering the energy it uses. When your gas tank is low, the only method to save energy is not to use it.


There is no need to be alarmed if your aircons’ gas levels are low. We sincerely hope this has been helpful for you and that it prevents any costly damages on your end.
