If you’ve noticed that your aircon isn’t cooling as effectively as before, one possible reason is that the refrigerant, or commonly known as “aircon gas” might be running low.
Many homeowners wonder how long aircon gas lasts and when it’s time for a refill. Understanding this can help you maintain your unit’s performance and prevent costly repairs in the future.
In this guide, we’ll explain how long aircon gas typically lasts, signs that it might be running low, and maintenance tips to help you keep your cooling system in peak condition.
For most air conditioning units, the aircon gas can last anywhere between 8 to 10 years, as long as the system is well-maintained and there are no leaks.
Unlike fuel, refrigerant doesn’t get “used up” during operation. Instead, it continuously cycles through the system to absorb and release heat.
However, if your aircon is not serviced regularly or has small leaks in the piping, the gas level may decrease much faster.
In such cases, you may need a top-up every 1 to 3 years depending on usage and the unit’s condition.
There are several factors influence how long the refrigerant lasts before it needs a refill:
If your aircon system wasn’t installed properly, there’s a higher risk of gas leakage from the start. Professional installation ensures tight sealing of pipes and correct gas pressure levels.
In countries like Singapore where air conditioners are used almost daily, the system undergoes more wear and tear, which may affect the longevity of the gas.
Inverter aircons often use newer refrigerants like R32 or R410A, which are more efficient and environmentally friendly. These gases tend to last longer compared to older types such as R22.
Regular aircon servicing helps detect early leaks, clean clogged filters, and keep the system running efficiently. Without it, small leaks can go unnoticed, shortening the gas lifespan.
If you suspect that your aircon gas is running out, here are some signs to watch for:
If you notice one or more of these symptoms, it’s best to call a professional technician to inspect and refill your aircon gas if necessary.
While some homeowners consider DIY solutions, it’s not recommended to refill aircon gas on your own.
The process requires specialized tools, proper safety measures, and knowledge of gas pressure levels. Incorrect handling could damage your system or even pose health risks.
Instead, contact a licensed technician who can safely check for leaks, vacuum the system, and refill it with the correct type and amount of refrigerant.
To extend the lifespan of your aircon gas and avoid unnecessary refills, follow these simple tips:
By maintaining your unit well, you’ll not only preserve the gas but also improve energy efficiency and extend your aircon’s lifespan.
The cost to refill aircon gas in Singapore typically ranges from $60 to $150 per unit, depending on the type of refrigerant and the size of your system.
Older models using R22 gas are gradually being phased out, so switching to a newer inverter model may save you money in the long run.
Regular maintenance from a trusted service provider can prevent expensive refills and ensure your aircon runs optimally year-round.
