Aircon Gas Top-Up Singapore — Get Your Cold Back, Not Just a Refill
If your aircon is running but not cooling the way it used to, low refrigerant gas is one of the most common causes. Our Gas Top-Up service checks levels accurately and tops up only what's needed.
Watch for these
Signs Your Aircon Needs a Gas Top-Up
A few common symptoms that usually point to low gas levels:
Book a visit- Aircon runs but the room doesn't feel cold enough
- Ice forming on the indoor unit or copper piping
- Longer time needed to reach the set temperature
- Hissing sound near the indoor or outdoor unit
- Compressor running constantly without cycling off
The cause
Why Gas Levels Drop Over Time
Refrigerant gas doesn't get "used up" through normal operation — a drop almost always points to a specific cause.
Book a visit- Small leaks at pipe joints or flare connections over time
- Wear and tear on older units with ageing copper piping
- Physical damage to piping during renovation or nearby work
- Manufacturing or installation issues on newer units, though less common
Why choose us
Why Homeowners Choose Us
Topping up gas without checking for a leak often means doing it again in a few months — we check first.
Book a visit- Leak check included before topping up, not just a quick refill
- Correct gas type and pressure used for your specific system
- Transparent pricing based on gas type and quantity needed
- Advice given if a leak repair is needed rather than repeated top-ups
- Pressure check — current gas levels measured against system specification
- Leak inspection — piping and connections checked for visible or detectable leaks
- Gas top-up — refrigerant topped up to the correct level for your system
- Performance test — cooling output checked after top-up to confirm the fix
Comparison
Gas Top-Up vs Leak Repair
It helps to know which one your unit might actually need before booking:
Book a visit- Top-up alone suits units with a very slow, minor drop in gas over years
- A confirmed leak should be repaired first, then topped up — not topped up repeatedly
- Repeated top-ups within a short period usually signal an undetected leak
- Older units with worn piping are more likely to need leak repair alongside a top-up
How do I know if my aircon needs gas or just a service?+
If cooling has weakened but airflow feels normal, it's more likely a gas issue — our technician confirms with a pressure check on-site.
Will you top up gas even if there's a leak?+
We'll flag any detected leak first, since topping up without fixing a leak usually means the gas drops again soon after.
How long does a gas top-up take?+
Typically 30–60 minutes per unit, including the pressure check and post-top-up test.
