2. Why Gas Top-Ups Aren’t a Long-Term Solution
Repeated aircon gas top-ups are unusual, especially after repairs or part replacements. If it becomes recurring, don’t just refill and move on. Schedule a professional inspection with Newway to identify hidden issues and perform accurate diagnostics.
Noticing that your aircon needs gas top-ups a little too often? It’s time to dig deeper. Unlike fuel in a car, aircon refrigerant doesn’t run out over time. Instead, it circulates in a sealed system, built to last for years without needing frequent AC gas refills. So if your aircon is not cold and keeps needing gas, it could be a sign of a leak or another issue. In this article, we’ll break down what might be causing the problem and how to fix it.
The most common reason for repeated aircon gas top-up requests is a refrigerant leak within the system. These leaks typically occur due to small cracks, loose fittings, or corrosion along the refrigerant lines. An aircon refrigerant leak is especially common in older units or systems that haven’t been well-maintained over the years. Left unchecked, even minor leaks can lead to poor cooling performance and increased energy consumption.
What to look out for:
A professional leak detection test during aircon servicing can help confirm the issue before it worsens.
Your aircon’s ability to cool effectively relies on maintaining the correct refrigerant pressure throughout the system. Two key components control this:
This component compresses the refrigerant and circulates it through the system.
The expansion valve regulates the flow of refrigerant into the evaporator coil.
If either of these components is faulty, it can cause a refrigerant pressure imbalance. This means the pressure is either too high or too low in parts of the system. When this happens, your aircon may struggle to cool your space properly, even if there’s enough refrigerant in the system. You might notice that the unit is running, but the air remains warm or only mildly cool. Over time, this imbalance can also put additional strain on the system, leading to reduced performance and higher energy costs.
Improper aircon installation in Singapore can lead to long-term performance issues, especially when it comes to refrigerant levels. During installation, it’s crucial to charge the system with the correct type and amount of refrigerant. Without meticulous handling, you’ll keep experiencing issues even after an aircon gas top-up.
For instance, overcharging the system may create excessive pressure, putting unnecessary strain on components. On the other hand, if the system is undercharged, there won’t be enough refrigerant to effectively absorb and release heat. This can result in poor cooling and higher energy consumption as the unit struggles to maintain the desired temperature. That’s why it’s crucial to have your unit installed and serviced by trained professionals who follow manufacturer guidelines.
Like all appliances, air conditioners naturally wear down over time. In humid climates, constant usage can cause seals to weaken, coils to corrode, and small refrigerant leaks to develop. Therefore, look out for signs your aircon may be reaching the end of its lifespan:
If these issues keep recurring despite regular maintenance, it may be more cost-effective to consider replacing the unit rather than continuing with frequent repairs.
Repeated aircon gas top-ups are unusual, especially after repairs or part replacements. If it becomes recurring, don’t just refill and move on. Here’s what to remember:
If your aircon is not cold despite multiple gas top-ups, schedule a professional inspection with Newway. Our experienced team can identify hidden issues and perform accurate diagnostics to keep your unit running efficiently year-round.
