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.
