Knowing The 8 Common misconceptions surrounding aircon gas topping – how often should you do it

8 Common Misconceptions Surrounding Aircon Gas Topping

Aircon gas topping is a key step to keeping your air conditioner working well. It’s when you add more cooling gas to the system. Some people think this isn’t important, but they are wrong.

Without enough gas, aircones don’t cool properly and can use more power – costing you more money! Experts say even if you lose just a little bit of gas, it can make your energy bill go up by a lot.

Looking after your aircon means checking and topping up the gas every year. This helps prevent breakdowns and keeps it running smoothly for longer. Topping up the gas is not something you should try to do yourself; it’s better to get help from someone who knows what they’re doing.

You might need more gas if your aircon stops making cold air or starts leaking water. If any of these things happen, it’s time to call in an expert.

Remember that good care will keep your unit running better and save money in the long run. The right amount of refrigerant is very important for keeping everything working right and avoiding big problems inside the machine according to Luce Aircon.

Debunking the Myths of Aircon Gas Topping

Amidst a swirl of misconceptions, it’s high time we set the record straight about aircon gas topping. Let’s dive into the common myths clouding this crucial aspect of air conditioner maintenance and reveal the truths that are often overlooked.

Myth 1: Aircon Gas Toppings Aren’t Necessary

Some people think aircon gas toppings are not needed. This is not true! Your air conditioning unit won’t work right without enough refrigerant gas. Like a fridge needs to keep things cold, your aircon needs this special gas to cool down the air.

If you don’t add more gas when it’s low, you might end up with big problems. The cooling performance gets worse and fixing it could cost a lot of money. It’s like running a car without enough oil; eventually, something will break and it’ll be expensive to fix.

So, keeping the right amount of gas in your aircon is very important for making sure it works well and doesn’t use too much energy.

Myth 2: Gas Topping Isn’t Part of Routine Maintenance

People often think gas topping isn’t needed with every aircon check. This is not true. Just like your car needs oil, your air conditioner needs gas to work right. The gas helps carry heat out of your house, keeping it cool.

Without enough gas, the system works harder and uses more energy.

Experts say you should add gas once a year to keep things running smoothly. Don’t skip this step in taking care of your aircon. If you do, you could face big repair bills later on. A professional technician can check if your system is sealed tight or if it’s leaking somewhere before adding more gas.

It’s important as part of regular air conditioning services to make sure everything is working well for when you need it most.

Myth 3: Gas Topping is Easy and DIY-friendly

Many folks think adding gas to their aircon is a piece of cake, something they can do themselves. This isn’t true! You need special tools and skills to put gas in an air conditioning system.

It’s not like putting air in your bike tires. Handling the gas wrong could hurt you or break your aircon.

Always call a pro when your aircon needs more gas. They know how to find leaks and fix them right. They have training on how to handle the gases safely and make sure everything runs smoothly.

If you try it yourself without knowing what you’re doing, you might cause big problems that cost lots of money later on. Trust the experts; they’ll keep your cooling system working great with no fuss for you!

Myth 4: It Doesn’t Affect Energy Efficiency

Some people think that not adding gas to their aircon won’t make it use more energy. This is a false belief. Aircons need the right amount of gas to work well and save energy. Without enough gas, the compressor works too hard, which uses more power and can break it.

Having enough gas helps your aircon cool your home better without using too much electricity. It’s like having just the right amount of fuel in a car – not too little, not too much – so it runs smoothly and doesn’t waste petrol.

Keeping your air conditioning system topped up with gas keeps it running efficiently and saves you money on energy bills in the long run.

Myth 5: Skipping Gas Topping Won’t Incur High Costs

Skipping gas topping can lead to big bills later on. Your air conditioner needs the right amount of gas to work well and use less energy. If you don’t add gas when needed, your machine has to work harder.

This means it uses more electricity and you pay more money for power.

Leaks in your air conditioning system can also cause harm. These leaks let out gas, which is bad for everyone’s health and safety. Fixing leaks early stops bigger problems and keeps costs down.

Always have pros check your system so they can find any issues before they get worse.

Myth 6: Professional Help Isn’t Required for Gas Topping

Some people might think they can top up their aircon’s gas by themselves. This isn’t a good idea. Air conditioners are complex machines with parts like the electrostatic unit and fan coil units that need special attention.

Only trained experts should handle these systems because they know how to find leaks, fix them safely, and fill the gas correctly.

Letting professionals do this job is smart because they have tools for leak detection and understand how the closed-loop system works. They ensure your air conditioning unit gets just the right amount of gas, which helps keep energy consumption low.

Remember, regular maintenance from someone who knows what they’re doing will help your aircon run better for longer.

Myth 7: Aircon Performance is Unaffected by Gas Levels

It’s not true that aircon performance stays the same no matter how much gas is in it. The right amount of gas makes sure your air conditioning system transfers heat well. If there isn’t enough, your aircon has to work harder and longer to cool down a room.

This means it uses more electricity, which costs you more money.

Keeping the correct level of gas helps avoid these problems and keeps your aircon working great. Just like a car needs the right amount of fuel to run smoothly, an air conditioner needs its gas levels checked and topped up by professionals to keep you cool without extra costs.

Myth 8: Frequent Gas Topping is Unnecessary

Many people think that they don’t need to top up their aircon’s gas often. But this isn’t true. Your air conditioning system needs the right amount of refrigerant gas to work well.

Without enough gas, your aircon can’t cool your room properly and will use more energy, making your bills go up.

Experts say that even a little less gas in the system can make a big difference. For example, if your aircon has 10% less gas than it should, you could pay 20% more on your electricity bill! So check your unit regularly for signs like warm air or water leaking.

If you see these signs, get a professional to help with topping up the gas. This keeps the unit running smoothly and stops bigger problems from happening later on.

When to Consider Aircon Gas Topping

Understanding when to opt for aircon gas topping is pivotal in maintaining the longevity and efficiency of your cooling system. Let’s delve deep into recognising the tell-tale signs that suggest it’s time to top up, alongside expert recommendations on how often this maintenance task should be performed to ensure optimal performance.

Signs Your Aircon Needs Gas Topping

Your air conditioner works hard to keep you cool. It might need a gas top-up if things don’t seem right. Here’s how you can tell:

  • The air from the aircon isn’t cold: When your room stays warm even though the AC is on, the gas might be low.
  • Your energy bills go up: If your power costs jump, it might mean your aircon is working extra hard due to low gas.
  • Ice forms on the pipes: Seeing ice on the air conditioning system’s pipes and coils can signal a gas issue.
  • The unit makes strange noises: Odd sounds coming from your unit could tell you that there’s not enough gas for proper function.
  • Airflow feels weak: Less cool air blowing out suggests it’s time for a professional check-up, possibly including a gas top-up.
  • The cooling takes longer than usual: When it seems like ages before the room cools down, this might mean the gas levels are down.

Recommended Frequency by Professionals

Aircon maintenance is key to keeping your cooling system running smoothly. Experts say you should top up your aircon gas every year. Here’s what professionals recommend:

  • Schedule a yearly check-up for your aircon gas. Just like a car needs regular servicing, your air conditioning systems need attention too.
  • Keep an eye on cooling performance. If the air isn’t as cold as it used to be, it might be time for a gas top-up.
  • Listen for strange sounds from the unit. Noise can mean there’s not enough gas and the system is working too hard.
  • Watch out for higher electricity bills. If it takes longer to cool your space, the unit uses more power and costs go up.
  • Check for ice on the coils. This could mean there’s too little gas and it’s causing parts of your aircon to freeze.


Remember, your air conditioner needs the right amount of gas to work well. Regular checks and topping up help it cool better and use less energy. Trust a pro to check for leaks and add gas when needed.

This keeps your cooling costs down and your aircon running smoothly. Take care of your air conditioner, and it will take care of you on hot days!
