Air conditioners (AC) are a lifesaver in the hot summer, but if not maintained properly, they can be dangerous.
One of the most common issues is a gas (coolant) leak, which can lead to poor cooling and even cause fires.
Let’s understand how AC gas leaks happen, the risks involved, and how to prevent them.
Why AC Gas Leaks Happen
There are various reasons why an air conditioner may stop working, but a gas leak is one of the most common and often overlooked issues.
Refrigerant gas is necessary for the AC to cool the air. If it leaks, the AC won’t cool properly. Worse, the leaking gas can be highly flammable.
While newer gases like R32 are less flammable, they are not entirely safe. A spark near a gas leak can lead to a fire.
Risks of Gas Leaks in ACs
Gas leaks in ACs can lead to serious consequences, including:
Cooling Failure: The AC will not cool the room efficiently, making it uncomfortable during hot weather.
Fire Hazards: Refrigerant gases are flammable. Even though R32 is less flammable, it still poses a fire risk if there’s a spark nearby.
Therefore, if you notice any problems with your AC, it’s crucial to have it checked right away.
How to Prevent Gas Leaks in Your AC
Though gas leaks can happen over time, there are steps you can take to minimize the risk:
Use Copper Coils: Copper coils are more durable than aluminum and don’t rust easily. This helps prevent leaks that can happen due to oxidation.
Proper Outdoor Unit Placement: Install the outdoor unit in a shaded area. This helps keep the system cooler and increases its lifespan.
Cover the Unit in Off-Season: When the AC isn’t in use (like during winter), cover the outdoor unit to protect it from dust and moisture.
Regular Servicing: Have your AC checked by a professional regularly to catch small issues before they become major problems.
Causes of AC Fires and How to Avoid Them
Gas leaks are a major cause of fires in ACs, but other factors can contribute to fires as well. These include:
Incorrect Installation: Poor installation can damage the AC, leading to various issues, including fires.
Loose Wiring: Faulty wiring can cause short circuits, which may start a fire.
Clogged Vent: A blocked vent causes pressure to build up in the compressor, which can cause it to overheat and burst.
How to Avoid Fires in Your AC
Get Professional Installation: Always have your AC installed by a professional to avoid any installation errors.
Check the Wiring Regularly: Ensure that wires are properly connected and in good condition to avoid short circuits.
Address Gas Leaks Immediately: If you notice a gas leak, turn off the AC immediately and get it repaired by an expert.
Keep the Blower and Vents Clean: Ensure proper airflow by cleaning the blower and vents to prevent pressure buildup in the compressor.
By following these preventive measures, you can significantly reduce the risk of gas leaks and fires in your AC.
