Numerous issues can occur with residential and commercial aircons when they are not adequately cleaned and maintained. Some of these include a faulty compressor, filthy air ducts, a defective inverter, and even aircon water leaks. Though these issues can be resolved via an aircon repair or replacement, an aircon gas top-up is also a feasible solution.


Why Do Some Units Require An Aircon Gas Top Up?


One of the advantages of having an aircon gas top-up performed is that it can enable a malfunctioning aircon to start working correctly once more. In fact, this particular aircon service can enhance an aircon in such a way that it produces cool and refreshing air much more efficiently.

Normally, an aircon gas top-up is required when an aircon unit starts releasing hot air. This is because lack of cold air usually results from low refrigerant levels. Remember that the condenser of any installed aircon requires enough refrigerant so that it can turn heat into liquid. Only when the evaporator receives an adequate amount of liquid can cold air be distributed.

In other instances, you will need to have an aircon gas top-up performed when you are experiencing an aircon water leak. Low refrigerant levels usually result in a decrease in aircon pressure which results in the evaporator coils becoming frozen. Once the ice on these components melts, water begins to collect on the drain pan which ultimately overflows.

Failure to have an aircon gas top-up performed when needed can result in major damage to your unit. When an air conditioner does not have sufficient gas levels, it can begin to overwork. This can ultimately lead to various aircon components sustaining damage which might prevent you from having enough aircon energy savings.


The Importance of Aircon Refrigerant and Why You Should Check It Periodically


Aircon systems require refrigerant gas to disperse cold air. This applies to all units irrespective of aircon brand or model number. Always remember that refrigerant gas ensures that the parts of an aircon function properly and at the proper rate.

Lack of refrigerant gas may result in heat accumulation within the condenser. Besides that, it can lead to the build-up of moisture and dirt inside the evaporator. When such issues are left unattended, various aircon emergencies can develop. Examples include a corroded gas storage chamber, smelly aircon, and damaged tubing.

You can see to it that your aircon works properly by monitoring your refrigerant gas levels from time to time. Moreover, this will help to prevent damage to vital aircon parts which might warrant expensive aircon repairs. You will also be able to decrease your aircon’s electricity consumption as a result.


Different Aircon Gas Types


Although the specific brand of gas an office or HDB aircon installation requires depends on its manufacturer, most aircons employ the following gas types:

  • R-22 Gas – older air conditioner models are more likely to run on this particular type of gas. Furthermore, it is widely used by car aircons, mini-split units, portable units, window units, and refrigeration systems. That said, the use of R-22 gas has declined over the years due to its environmentally harmful composition. As a matter of fact, its manufacture and usage in various residential and office aircons have been banned.

Normally, it costs $100 to $350 to refill R-22 gas. For older models, however, the price is estimated at $600 and above.

  • R-410 Gas – referred to by some as Puron, this type of gas is widely employed for most aircon installations today because of its decreased impact on the environment, its minimal production cost, and its efficiency. Generally, a refill for this gas costs $350. However, this price can vary based on the size of the unit undergoing a gas top up.
  • R-404 Gas – this specific gas type was once regarded as a viable alternative to R-22. However, its use in most modern aircon installations has either been banned or phased out in most countries due to its toxicity and its devastating environmental effects. 

Check the seal of your aircon’s refrigerant gas or its packaging to determine precisely what type of gas your Daikin aircon or Mitsubishi aircon requires. After you have identified the name, model, and model number for your aircon’s gas, you can proceed to order it easily online.

Always keep in mind that it is essential to obtain the correct type of gas for your aircon. If your unit employs a particular gas type other than the one it needs, it can end up experiencing some aircon issues such as the following:

  • Faulty condenser or compressor can result in excess moisture
  • Noisy Aircon
  • Poor Air Quality
  • Bad Aircon Smell
  • Overheating
  • Higher Power Usage


How Is An Aircon Gas Top Up Performed?

Aircon gas top-ups typically do not take too long to finish. As a matter of fact, the following steps can be finished in just an hour:

  1. The technician checks the condition of the aircon. This process includes detecting aircon leaks and other issues that might be preventing the unit from functioning as needed.
  2. Once they have confirmed that there is a lack of refrigerant gas, the technicians insert a tube into the tiny pipe behind the unit. This provides it with a connection to both the gauge and gas tank.
  3. At this stage, the technician makes use of the gauge to calculate how much gas should be refilled and the cost for this amount.
  4. Upon determining the specific amount of gas that needs to be refilled as well as its price, the technician goes on to do an aircon gas top up.
  5. After the gas top up process has been concluded, the technician switches on the installed aircon. As the unit powers up, they make sure to see if there are other aircon repair symptoms that need to be addressed.


Important Things To Take Note Of When Availing An Aircon Gas Top Up


If you think that your unit requires an aircon gas top-up, here are some essential points to take note of:

  • Before proceeding to perform an aircon gas top up, reputable aircon servicing companies always see to it that a series of tests are done. This includes the detection of aircon water or gas leaks and faulty or dirty aircon parts. Avoid any aircon maintenance company that fails to carry out this procedure.
  • Well-trained aircon technicians always inspect the type of gas an aircon requires before performing an aircon gas top up.
  • Before you decide to avail of an aircon gas top-up, do not forget to consider the type and size of the aircon you have installed.
  • Be sure to confirm that your aircon problems are not caused by any other issues that could be resolved through a simple aircon repair before you have an aircon gas top-up performed.
  • Have an aircon gas top up performed at least once a year to prevent any issues that might cause your aircon to require additional maintenance.
