How Does The Process Of Gas Top-up Works?

Air-conditioners use liquid or gas as a refrigerant for the air that will be delivered to cool a room or space. Over time, it’s possible that there will be refrigerant storage leaks, and the chemical slowly seeps out, emptying the container.

Top-ups of gas replace the chemical gas coolant in your air conditioner’s refrigerant storage unit so that your air-conditioner can continue to work at high efficiency and last for a longer time. A multitude of factors may lead to gas leakages, but the common few include improper installation, poor quality copper pipe, as well as simple depreciation over time.

Professionals usually use a gauge to check for the refrigerant level inside your air-conditioning unit., checking the level of gas needed. Then, a refrigerant tank will be used to charge up gas into the air-conditioner so that the gas levels go back to normal.

** Do note that different companies may cover various aspects, not all companies provide the same level of service.

1. Initially, we examine the cooling coil and get a feel of it with our hands to see if a gas top-up is required.
2. If the cooling coil isn’t cold enough, we’ll check the air conditioning gas level.
3. We’ll then check the gas level in your unit.
4. The cost of refuelling the air conditioner will be determined by the amount of gas required.
5. Following that, we’ll fill up the gas tank.
6. We’ll use the gauge to check the gas level one last time.
7. Finally, we’ll examine other components to ensure that everything is in working order.

Can we top up AC gas?

Yes, AC gas can be topped up if the levels are low. However, it’s essential to address any underlying issues, such as leaks or faulty components,s before refilling the gas to prevent future problems.

How do we know if AC gas is low?

Signs of low AC gas include reduced cooling efficiency, warm air blowing from the unit, unusual hissing sounds, or ice forming on the coils. If you notice these symptoms, it’s important to check the gas levels.

Can we run the AC without gas?

Running an AC without sufficient gas can damage the compressor and other components. It’s crucial to ensure the refrigerant levels are adequate to maintain the unit’s functionality and prevent costly repairs.

How do I know if my AC needs gas?

If your air conditioner is not cooling effectively, producing warm air, or has ice build-up on the coils, it may need a gas refill. These signs typically indicate that the refrigerant levels are too low.

How long should aircon gas last?

Under normal conditions, aircon gas should last around 1 to 3 years. However, if the gas is leaking or the unit is not maintained properly, it may need to be topped up more frequently.

Why is my aircon not cold?

Your aircon may not be cooling due to low refrigerant levels, a clogged air filter, a malfunctioning compressor, or a blocked condenser coil. It’s essential to have the unit checked by a technician to identify the exact cause.
