Signs You Need an Aircon Gas Top Up

You may need a gas top up if you notice any of the following:

Warm aircon

Your aircon is blowing warm or mildly cool air despite being set to the lowest temperature

Slow cooling

The room takes significantly longer to reach a comfortable temperature

Ice on unit

Ice or frost is forming on the indoor unit or refrigerant pipes

If you are seeing more than one of these signs, there is a good chance your refrigerant levels are low.

Our Aircon Gas Top Up Process

We follow a structured, step-by-step process on every job. 

01

Full System Inspection

Our technician inspects your indoor and outdoor units for visible damage, wear, or loose fittings before touching the refrigerant

02

Gas Level Check

We check your refrigerant levels using a gas gauge to determine if a top-up is needed and how much refrigerant is required.

03

Identify the Correct Gas Type

Different aircon models use different refrigerants. We check your unit’s specifications and top up with the correct gas (R22, R410A, or R32) in the right quantity.

04

Recharge and Test

We refill the refrigerant to the manufacturer’s recommended level and test the system for cooling performance, pressure, and proper operation before we leave.

Why Choose Jex Aircon for Your Gas Top Up?

Proper Process

Some aircon companies skip steps during a gas top-up, which can cause more harm than good. Our technicians follow the correct process on every job.

No Shortcuts

Topping up without checking existing gas levels, using the wrong refrigerant, or introducing moisture into the system can damage your compressor and shorten your aircon’s lifespan. We make sure none of that happens.

Correct Refrigerant, Correct Quantity

Overcharging or undercharging refrigerant can damage your compressor. Our technicians are trained to refill to exact manufacturer specifications every time.

All Brands, All Refrigerant Types

From older R22 units to the latest R32 models, we handle every aircon type across Singapore’s residential and commercial properties.

Transparent pricing

No hidden fees. No hard selling. We tell you what needs to be done and why, and you decide.

Island-Wide Service

We cover all areas of Singapore. From HDB flats in Tampines to offices in the CBD, our team comes to you.

Very irresponsible and incompetent workers. Constantly late for appointments even turning up when dark. Failed flaring job causing gas to run out in a month. Subsequent appointments with only single worker with no gas. Supervisor Muru unapologetic, dismissive and rude. An entire bunch of work permits holders running the show. The business owner Jack Soh will only double charge despite a failed job. Unscrupulous!

I wanted to instal a system 4 aircon in my old 4 room HDB flat. I correspond with Jex aircon via WhatsApp and I am very pleased with the assistance and advise of Kristin. First, she gave me an estimate of the cost, then she arrange a site visit. Jack came to do the site visit and explained clearly where the aircon can be installed and how the pipes will run. I requested for more detailed information on the materials to be used and Kristin answered all of them. I asked further questions on changing the location of the compressor, warranty and cleaning up the place. Kristin patiently answered all my questions and even sent me a photo of my HDB flat to confirm that the compressor can be placed outside the room I wanted as other neighbours had done the same thing. Kristin had impressed me by doing such a good job and deserved a compliment. I hope her bosses will read this post and acknowledge her good work. The installation will be done on 24 sept and I am confident of the service of the company

Jex Aircon supplied and installed a mitsubishi system 4 for my new flat a d they were very professional about it! They were knowledgeable and had great recommendations such as reminders about not positioning the bedroom aircon at the foot of the bed so that servicing would not require people to go to the bed, as well as warning us about putting the aircon above the TV in prevention of potential leakages. We proceeded with installing above the TV anyway for aesthetic purposes oops. Still a really great experience with them, not to mention their prices were very competitive and affordable!

​Engaged them for a chemical overhaul to fix a leaking aircon. The technician arrived on time, thoroughly cleaned the unit, flushed the drain pipe, and checked the gas levels. ​ Highly recommended!

Frequently Asked Questions

1. Why Does My Aircon Need a Gas Top Up?

Your air conditioner runs on a closed loop. The refrigerant inside does not get used up, it circulates continuously. So if your aircon is low on gas, it means refrigerant has escaped through a small crack, loose fitting, or worn-out component somewhere in the system.

This can happen to any unit. It is not always about age or brand. Wear and tear accumulates gradually even on well-maintained units.

The good news is that a gas top up usually restores your cooling effectively. For most units, the next top up is only needed after a year or more.

If your aircon loses gas again within a short period, that points to a more significant leak. At that point, a leak check, though time consuming and expensive, is worth considering to find and fix the source. Otherwise the costs add up over time.

At Jex Aircon, we will let you know honestly what we observe during the top up and advise whether further checks make sense for your unit.

Our gas top up prices start from $100 and depend on the size of your system. However, our aircon gas top up prices are the same regardless of whether your unit uses R22, R410A, or R32. View our full pricing above or WhatsApp us with your model number for a quick quote.

The most common signs are warm air blowing from the unit, a room that takes longer than usual to cool down, ice forming on the pipes or indoor unit, and unusually high electricity bills. A hissing sound is a strong indicator of an active gas leak.

No. Handling refrigerant requires specialised equipment, technical training, and licensing. Improper handling can damage your compressor, void your warranty, and pose a health and safety risk. Always use a qualified technician.

We carry out gas top ups for all aircon brands available in Singapore, residential and commercial. If your unit cools a space, we can do gas top ups for it.

A standard top up takes about 30 minutes per system. 

Under normal conditions, a well-maintained aircon should not need regular gas top ups. If your system is frequently losing gas, it means there is an ongoing significant leak that needs to be repaired, not just topped up repeatedly. We recommend a full inspection if you have needed more than one top up in the last 6 months.

Not always. Poor cooling can also be caused by a dirty evaporator coil, a blocked filter, or a faulty compressor. None of these require a gas top up. Our aircon technician will diagnose the actual cause before recommending any service.

R22 is an older refrigerant being phased out globally. R410A is the current standard in most Singapore homes. R32 is the newest generation, found in high-efficiency models released in the last few years. Using the wrong refrigerant will damage your unit, which is why we always verify the correct type before topping up.

Yes. We cover all residential and commercial areas across Singapore from the north to the south, HDB estates to landed properties and office buildings.
