An air-conditioner uses liquid or gas as a refrigerant for the air that will be delivered to cool a room or space. Freon or Puron are examples of these chemicals found inside refrigerants which are found inside the air-conditioner.
In most cases, cooling chemicals inside the refrigerant of an air-conditioner does not get used up throughout the service life of the unit. But, there are cases where the refrigerant storage leaks and the chemical seeps out slowly emptying the container.
An aircon gas top up is an option to re-fill the refrigerant storage unit with the chemical gas coolant used by your air-conditioner. The aircon technician first takes care of the hole or damage causing the leak of the substance which is followed by topping up to fill the newly-repaired container with cooling gas.
This procedure keeps the cooling process going for your air-conditioner. It is also crucial to top up your refrigerant when required to prevent your whole AC system from completely breaking down because of low refrigerant gas level.
Why It Is Important to Check and Top Up Gas?
Gas leaks happen to air-conditioners and will directly affect the unit’s efficiency. Aside from your room not getting cold enough, the compressor does not benefit from the cooling effect of the gas which eventually causes it to overheat and fail.
The evaporating coils receive the cold gas from the refrigerant and if it’s not cold the evaporator will stop operating. Refrigerant chemical leaking from your AC can be harmful to the environment if it gets to the water system.
Type of Gas Available for Top Up
In the past, Freon was the preferred type of gas used as coolants in air-conditioning units around the world. However, nowadays there are alternative chemicals used as refrigerants in newer models of air-conditioners. Let’s explore the two most popular ones used today:
The R22 Gas used in air-conditioners is are classified as HFC (Hydroflourocarbon) a type of chemical that when released to the environment will affect the ozone layer of the atmosphere. Its use is now being phased out all over the world with a few countries instituting a total ban for the use of this gas in the manufacturing of air-conditioning units.
For units still using the R22 gas, it is still an effective coolant for air-conditioning units. Manufacturers have used R22 because of low compressor displacement. This means the compressor can cool the air more efficiently and will consume less power to cool the incoming air.
An R22 refrigerant also helps in absorbing water that is produced during the cooling process away from the refrigerant system. This is crucial in keeping the refrigerant part from getting water in it which will affect how it operates.
R22 refrigerant is now an expensive chemical when the unit needs replacement. It is sold on a per pound basis which can cost up hundreds of dollars. This can prove to be costly if the refrigerant is at a low level.
R410 is the newest refrigerant being used by air-conditioner manufacturers. Puron is the most popular brand name for this chemical. Cooling efficiency is like the R22 refrigerant but is not hazardous when it gets exposed to the environment.
Storing the R410 inside the air-conditioner is much easier because a smaller amount of the chemical is needed to generate the same cooling effect. It is an economical choice for manufacturers since they have more design options for their AC units.
The refrigerant works under high pressure which makes it a more durable coolant. It also transfers heat better than an R22 which means overheating won’t be an issue when using your AC system. AC owners can upgrade for an R410 refrigerant if they want to get the many benefits of this chemical.
A jug containing R410 refrigerant weight about 25 pounds in the market and will cost at least $25 per pound. The more expensive variants can cost up to $75 per pound. After buying, make sure to get a professional aircon technician to do the replacement or upgrade.
The Process of Top Up Gas
Aircon gas top ups can only be done effectively and safely by a professional technician. They use a gauge to check for the refrigerant level inside your air-conditioning unit. It will tell them the level of gas that needs to be filled into the refrigerant storage.
A refrigerant tank will be used to charge up gas into the air-conditioner so that the gas levels go back to normal. This will be tested back again using the gas gauge to ensure that your AC will have enough refrigerant inside.
Your aircon technician will only use the right type of gas to refill your refrigerant storage. It is not safe to use an R410 tank on an R22 tank and vice versa. Aside from that, the technician will also recommend repairs to the refrigerant unit if it has damaged so that it won’t leak anymore. Other faulty components need to be checked to ensure the safety of the unit.
