Aircon Gas Leaking – Cause, How to Detect and Repair

Detecting and repairing an aircon gas leak may seem daunting, but with the right information, it can be a relatively simple process. There are a number of ways that air conditioning gas can leak. Detection and repair are important to avoid health hazards and maintain the efficiency of the system. In this article, we will explore the causes and effects of AC gas leakage and how to detect and fix it. We will also provide some tips on how to prevent future leaks.

When you are faced with aircon gas leaks, your first priority must be addressing the problem at hand to protect yourself and other people from danger. You should call professionals as soon as possible so they can find out what needs fixing, topping gas or replacing on this machinery before anything else happens!

What Causes Aircon Gas Leak?


Air conditioners are not immune to the effects of corrosion and can be vulnerable in some environments. Formicary corrosion causes pitting on air conditioner components and leads directly towards leaks that require repair or replacement – often at great expense! The condensing coil is constantly attacked by the chloride and fluoride ions, which cause it to leak refrigerant. This type of corrosion can be triggered in several ways, such as exposure to acetic or formic acids found on your hands when working with paints/solvents etc.

Poorly Soldered Controls of Fittings

Soldering is a common issue in the air conditioning industry. A cold joint caused by improperly melted solder can lead to gas leaking, just as an overheated or disturbed soldered will also cause gas leak intrusion from your unit’s joints which could explain why you’re experiencing such terrible smells!

Control Valves Leaky Connections

A malfunctioning Schrader valve is the most common cause of refrigerant gas leak problems in an air conditioner system. Sometimes, the seal covering this important piece gets damaged, and you will have trouble with your aircon units!

Refrigerant Lines Mechanical Damage

The act of moving refrigerant between the outdoor condenser coil and indoor evaporator of your air conditioning units can be a dangerous task for homeowners. If this line is damaged, it could lead to a gas leak that will cost you more in repairs than just buying another unit!

Signs of Gas Leakage

Frozen Evaporator Coils

When an AC refrigerant leak occurs, the moisture around these coils can freeze and thickly coat them. This leaves you with a damaged or dirty evaporator that needs cleaning before it leads to more serious problems such as gas leaking from its base, which could cause dangerous explosions! Be sure to check for last time how often your unit has been cleaned because most likely, all this entails is just a dusty air filter.

Not Enough Cooling

An AC gas leak would cause the air conditioner unit to malfunction as it does not have sufficient coolant due to coolant leaking. Your machine may even short cycle – turning off and on at short intervals! If you’re noticing that your AC is emitting warm air instead of cool air, then there’s a good chance it’s leaking gas.

Sweet Smell

If you notice a sweet, chloroform-like smell coming from your home’s air conditioning units, then there could be a coolant gas leak. This may indicate that electrical wiring in the machine has gone bad and started fires caused by freon gas burning off, giving off exhaust fumes instead of escaping through ventilation holes like normal moisture does when it evaporates over time.

High Electricity Bill

Have you been noticing your air conditioners using more electricity than usual? If so, that could be because of a leak in the refrigerant. This will cause an increase in bills as aircon leaks makes the unit work harder to provide cool air with insufficient fluids or gas!

Hissing Sound

The hissing sound of cooling pipes is an indication that there’s a gas leak in your air conditioning system. The escaping gases are coming from the thermostatic expansion valves, and they’re too narrow for them to go away without creating some noise!

The hissing sound coming from your air conditioner may indicate a refrigerant gas leak, so it’s important to turn it off and check for signs that could point toward an issue. You should also have someone who knows what they’re doing take care of this as soon as possible because there are irreversible consequences when dealing with high-pressure gas lines!

Dangers of Aircon Gas Leaks

Your Health

Many health hazards can arise from this. For one thing, it may lead to headaches and nausea due in part to CFCs, which readily absorb heat when they contact liquid or solid surfaces (including human skin). Prolonged exposure could also cause frostbite! While short-term problems include reduced coordination skills over time, chronic conditions may develop such as tremors, convulsions, and increased heart rate – all resulting from exposure to long-term ac gas leaks.

Aircon Damage

Air conditioning unit gas leaks are the main culprit for increasing your electricity bill. One study found that a leaking AC consumes almost 20% more energy, while constantly using one with an ongoing leak can put excessive pressure on compressors, leading to their ultimate failure!

Where to Find AC Gas Leak

Preventing Aircon Leaking Gas

Schedule Maintenance Checkups

The key to preventing an AC gas leakage is prevention. Don’t just contact a professional technician when there’s a problem with your unit; instead, schedule regular maintenance so that they can find any underlying issues or weak points before they turn into problems!

Use an Aircon Leak Detector

Gas leak detectors are a safe and effective way to sniff out air conditioning leaks. The device can detect traces of refrigerant gas on coils, out of pipes or even in outdoor condenser tubes without any danger whatsoever! This is much better than doing dye tests which might create toxic fumes that could hurt you and cause fires if not careful.

Be Mindful of What You Store Nearby

Don’t store anything flammable near your air conditioner, as this could create a dangerous situation if a gas leak occurs!

Check for Leaks Regularly

Even if you’re not using your air conditioner, it’s important to check for leaks regularly. This can be done by looking for any signs of moisture or condensation around the unit, as this could indicate a refrigerant leak. It would be best if you also listened for any hissing sounds, as this could also be a sign of a gas leak. If you do notice any leaks, it’s essential to contact a professional AC technician so they can fix the problem before it gets worse!

Final Thoughts

Air conditioner gas leaks are dangerous because they can increase your electricity bill, cause health problems, and damage your AC unit. It’s important to schedule regular maintenance checkups, use a gas leak detector, and be mindful of what you store nearby. You should also check for leaks regularly and contact a professional if you notice any.
