It's leaking. We pressure-test the closed refrigerant loop before adding any gas, so you pay once and the fix lasts. R22 (legacy units) is priced at about $25 per pound; R32 and R410A vary by system size. If we find a leak, you'll get a flat quote for the repair before we add anything. - Leak check before refilling - no top-up if there's a leak - R22, R32, R410A refrigerant types handled - Transparent per-pound pricing (R22 from ~$25/lb) - Combined with repair when a leak is confirmed - Same-day availability for most island areas ![Gas Top-Up demonstration](/images/misc/singapore-aircon-technician-demonstrating-service-.webp) FC Aircon Servicing handles R22, R32, and R410A refrigerant top-ups across Singapore, with over 20 years of hands-on experience servicing all major brands. We often hear from homeowners who assume a quick gas refill will fix their warm rooms - but a refrigerant top-up only works when the sealed loop is intact. The reality is different. Our technicians will show you exactly how to solve this permanently. Whether you live in an HDB flat, condo, or landed property, the diagnostic process is the same. Let’s go through the steps together. ## Why We Pressure-Test Before Every Refill Our team knows that most calls about weak cooling turn out to be a physical refrigerant leak. Sealed refrigerant loops in Daikin, Mitsubishi, Panasonic, and other major brands do not lose gas naturally. A tiny gap in the copper pipework is usually letting the refrigerant escape. We have seen homeowners pay for a refill only to have the gas escape again within days. Vibration from everyday operation often loosens copper pipe connections over time. Topping up the system without finding that hole is a terrible waste of money. FC Aircon Servicing’s technicians refuse to let you pay twice for the exact same problem. A proper pressure test must always come first. This crucial step protects your wallet and guarantees a lasting fix. ### How the inspection works We connect a manifold gauge to the Schrader valve to read the existing pressure levels. An MSA Safety electronic leak detector then traces along the copper lines to pinpoint the fault. Injecting nitrogen gas into the pipes helps reveal the precise location of hidden drops. Our technicians will give you a flat, transparent quote for the repair before adding any chemical. Here are the most common places where these annoying faults hide: - **Worn copper pipe joints:** Everyday vibration loosens these connections. - **Corroded outdoor condenser coils:** Humid weather eats away at metal parts. - **Damaged indoor evaporator coils:** Dirt buildup and moisture create tiny pinholes. ## R22, R32, R410A Refrigerant Types Explained Understanding the different refrigerant types inside your aircon is essential. We work with three main refrigerants daily to keep homes across Jurong West, Bukit Batok, Tampines, and the rest of Singapore comfortable. Each refrigerant carries different rules, costs, and environmental impacts. Here is exactly what you need to know about your specific setup. ### The legacy R22 systems Our advice is to plan for a replacement if your system uses this older gas. This older chemical typically powers air conditioners that are 15 years old or more. Singapore will see a complete import ban on R22 by 2030 under the Montreal Protocol. Expect skyrocketing repair costs as supplies shrink. Prices for this phasing-out chemical keep climbing rapidly every year. A modern upgrade is the smartest financial decision. ### The transitional R410A units Our inventory still holds plenty of this gas to service existing machines. You will find this chemical in most mid-2000s to early-2020s installations. The National Environment Agency prohibited the supply of new R410A room units back in October 2022. We recognize that its high Global Warming Potential rating made it obsolete for new manufacturing. The phase-out process for this product involves a few key points: - **Slower transition:** It is not facing an immediate total ban like R22. - **Wide availability:** Parts and servicing remain fully accessible for now. - **Eventual replacement:** You will eventually need to upgrade when the unit fails. A proactive approach saves you from sudden breakdowns. ### The modern R32 standard Our customers love how easily these systems achieve a coveted NEA 5-tick energy efficiency rating. This is the current default for all new installations across the island. It boasts a significantly lower Global Warming Potential of just 675. We always check your exact model to ensure absolute compatibility before beginning work. The refrigerant type is permanently fixed by your hardware. You cannot simply pump a modern chemical into an old legacy machine. ## How Much Does a Refrigerant Refill Cost in Singapore? FC Aircon Servicing keeps pricing fully transparent so you know exactly what to expect. Unlike a routine aircon servicing visit, a refrigerant refill depends heavily on your specific unit size and the gas type required. Average market rates in 2026 show that a complete top-up ranges from S$60 to S$200. Our standard quotes for the chemical itself are completely separate from any required patching work. Here is a breakdown of the typical per-pound rates you will see today: | Refrigerant | Typical per-pound rate | Typical system charge | | --- | --- | --- | | R22 | From ~$25/lb | 1-2 lbs (System 2), 3-5 lbs (System 4) | | R32 | ~$30-$40/lb | 1.5-2.5 lbs (System 2), 3-5 lbs (System 4) | | R410A | ~$35-$45/lb | 2-3 lbs (System 2), 4-6 lbs (System 4) | A standard R32 refill on a compact System 2 runs roughly $60 to $100. We see larger System 4 setups demanding more volume, which typically costs between $120 and $200. Budgeting for proper leak detection helps you avoid repeated fees. A professional nitrogen pressure test usually adds an extra $150 to $350 to the final bill. ### How Do We Compare to a Typical Provider? | Feature | Typical Provider | FC Aircon Servicing | | --- | --- | --- | | Leak check before refill | Often skipped | Mandatory on every job | | Pricing transparency | Quoted after work | Written quote before any work starts | | Refrigerant types | R22/R410A only | R22, R32, and R410A | | Availability | Business hours | 24/7 including weekends | | Experience | Varies | 20+ years, 1,000+ jobs completed | ### How to Avoid Common Gas Top-Up Pitfalls Our technicians always warn homeowners that skipping the diagnosis guarantees the problem will return. Unscrupulous contractors might skip the leak check entirely just to make a quick buck. Paying S$50 for a careless job costs more when you have to repeat it two weeks later. If your unit needs deeper attention, a chemical wash [/aircon-chemical-wash/ →](/aircon-chemical-wash/) or chemical overhaul may be the better first step before any refrigerant refill. ### Next steps for a cooler home Here is how to make the most informed decision for your property. For deeper context on which chemical your unit uses and when to plan a replacement, see our refrigerant types guide [/guide/r22-r32-r410a-aircon-refrigerant/ →](/guide/r22-r32-r410a-aircon-refrigerant/) .

FC pressure-tested first, found the leak in the indoor coil, fixed it once - problem gone." Aravind Kumar Sengkang ★★★★★ "Old R22 unit, needed a top-up. Honest about the phase-out, did the work, told us when to plan a replacement. No upsell." Mei Ling Bedok ## Gas Top-Up — common questions Why won't you just top up my gas? Because most low-cooling cases aren't low refrigerant - they're a leak that's been losing refrigerant. Topping up a leak buys you about a week; finding and fixing the leak gives you back the unit. What does R22, R32, R410A mean? Different refrigerant chemistries. R22 is the legacy refrigerant being phased out worldwide (still in older Singapore units). R32 is the current Singapore standard. R410A is common in mid-2000s to early-2020s units. We handle all three. How much refrigerant does my unit hold? Depends on system size and pipe length. A System 2 typically holds 1-2 lbs; a System 4 holds 3-5 lbs. We charge to manufacturer spec, not estimate. Can I top up R22 forever? Practically no - R22 is being phased out worldwide and prices keep rising. For R22 units past 10 years, we usually have a frank conversation about R32 replacement. Will a gas top-up fix poor cooling immediately? Only if low gas is the cause. If the coil is dirty, the filter is blocked, or the compressor is weak, gas top-up won't help. Diagnosis matters. Do you do same-day gas top-up? Yes - refrigerant is standard van stock. Most callouts include the top-up in the same visit if no leak is found. ## Related guides for Gas Top-Up Dig deeper into the decisions, costs, and troubleshooting that come up around gas top-up.
