Why does my AC have water dripping? How much do AC repairers cost in Australia?

Few things cause homeowners as much concern as a water leak, except perhaps the fear of mouldy carpet, which happens to be the top household fear searched on Google.

Both leaks and mould can result from an AC unit leaking water. If you’re here, it’s likely because your air conditioner is leaking, and you’re seeking solutions to fix it.

Ignoring AC water leaks can lead to costly and time-consuming repairs.

But don’t fret—you’ve come to Sealed, where we specialize in finding solutions to ensure your AC unit operates as efficiently as possible.

Why does my AC have water dripping?

If you’ve ever noticed water dripping from your air conditioner (AC) unit, you’re not alone. It’s a common issue that many people encounter, but understanding why it happens and what you can do about it can help you keep your home comfortable and your AC functioning properly.

Firstly, let’s break down why your AC might be dripping water:

1. Condensation: One of the primary reasons for water dripping from your AC is condensation. When warm air from inside your home is pulled into the AC unit, it passes over the evaporator coils. These coils are very cold because they’re filled with a refrigerant that absorbs heat from the air. As a result, moisture in the air condenses on the coils, much like how water droplets form on a cold drink on a hot day.
2. Drainage Issues: Your AC system is designed to collect this condensed moisture and drain it away from the unit through a drain line. However, if the drain line becomes clogged or blocked, the water can’t properly drain, leading to overflow and water dripping from the unit.
3. Dirty Filters: Another common culprit is dirty air filters. When the filters are clogged with dirt, dust, and other debris, airflow through the system is restricted. This can cause the evaporator coils to become colder than usual, leading to excessive condensation and potential water leakage.
4. Low Refrigerant Levels: If your AC system is low on refrigerant, it can cause the evaporator coils to become too cold, leading to excessive condensation and water dripping.
5. Improper Installation: Sometimes, the root cause of water dripping from your AC unit is improper installation. If the unit is not installed level or if the drain line is not properly connected, it can lead to drainage issues and water leakage.

Now that we’ve identified some common reasons for water dripping from your AC unit, let’s discuss what you can do to address the issue:

1. Check and Clean the Drain Line: Start by inspecting the drain line for any clogs or blockages. If you notice any debris, carefully remove it using a vacuum or a pipe cleaner. You can also flush the drain line with a mixture of bleach and water to clear out any buildup.
2. Replace Dirty Filters: If your air filters are dirty, replace them with clean ones. This will help improve airflow through the system and prevent the evaporator coils from becoming too cold.
3. Schedule Professional Maintenance: Regular maintenance by a qualified HVAC technician can help prevent issues like clogged drain lines and low refrigerant levels. A professional can also ensure that your AC unit is installed correctly and functioning properly.
4. Monitor Refrigerant Levels: If you suspect that your AC system is low on refrigerant, contact a professional HVAC technician to inspect the system and recharge the refrigerant if necessary.

Is it bad to run AC with a leak?

Running your air conditioner (AC) with a leak might seem like a temporary solution to keep your home cool, but it can lead to various problems and potentially costly consequences. Let’s delve into why it’s not advisable to run your AC with a leak and what could happen if you do.

1. Refrigerant Loss: One of the primary concerns with running an AC with a leak is the loss of refrigerant. Refrigerant is the substance responsible for cooling the air in your AC system. When there’s a leak, refrigerant gradually escapes from the system, leading to a decrease in cooling efficiency. As the refrigerant level drops, your AC will struggle to maintain the desired temperature, resulting in increased energy consumption and higher utility bills.
2. Reduced Cooling Capacity: As the refrigerant continues to leak, the cooling capacity of your AC diminishes. This means that your AC will take longer to cool your home, or it may not be able to reach the set temperature at all. You might notice that certain rooms feel warmer than others, or that your AC runs continuously without adequately cooling the space. Ultimately, running your AC with a leak compromises its ability to keep your home comfortable during hot weather.
3. Increased Wear and Tear: When an AC system operates with low refrigerant levels due to a leak, it puts additional strain on its components. The compressor, which is responsible for circulating the refrigerant, has to work harder to compensate for the loss. This can lead to overheating and premature wear and tear on the compressor and other vital parts of the AC system. Continued operation under these conditions can significantly shorten the lifespan of your AC unit and may result in the need for costly repairs or replacement.
4. Icing and Frost Formation: Another consequence of running an AC with a refrigerant leak is the potential for icing and frost formation on the evaporator coils. Refrigerant leaks can cause the evaporator coils to become colder than normal, leading to excessive condensation and the formation of ice or frost on the coils. This further impedes the heat exchange process and reduces the efficiency of the AC system. Additionally, ice buildup can damage the coils and other components if left unaddressed.
5. Environmental Impact: Refrigerant leaks not only affect the performance of your AC system but also have environmental implications. Many refrigerants used in AC systems, such as hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs), are potent greenhouse gases that contribute to ozone depletion and global warming. By allowing refrigerant to leak into the atmosphere, you’re not only wasting a valuable resource but also contributing to environmental harm.

Running your AC with a leak is not advisable due to the potential consequences it can have on your comfort, energy efficiency, and the lifespan of your AC system. If you suspect that your AC has a refrigerant leak, it’s essential to have it promptly inspected and repaired by a qualified HVAC technician. Addressing the leak early can help mitigate further damage and ensure that your AC operates efficiently and effectively.

How much do air conditioning repairers cost in Australia?

Air conditioning specialists may bill by the hour or by the job. Here’s a rough estimate of hourly rates:

• For domestic air conditioning, it could range from $80 to $110 per hour plus GST.
• For commercial air conditioning, it might be between $80 and $140 per hour plus GST.

The total cost depends on factors like the type of service needed, the duration of the job, whether replacement parts are necessary, and your location. Rates can vary locally, so it’s best to request quotes from at least three air conditioning technicians near you for an accurate estimate.

Air conditioning repair costs can vary based on the type of system you have. Typically, you might expect:

• Ducted air conditioning repairs: $70 to $130
• Split system repairs: $85 to $160
• Gas heating repairs: $95 to $180
• Inverter air conditioning repairs: $100 to $190
• Multi-split system repairs: $120 to $220
• VRV system repairs: $140 to $250

The nature of the problem also influences repair costs. For instance:

• Replacing air filters might cost $70 to $100.
• Resetting the thermostat could range from $108 to $250.
• Replacing a circuit board might cost $120 to $600.
• Replacing refrigerant might range from $160 to $400.
• Fixing leaks could cost anywhere from $225 to $1,600, depending on severity.

Regular servicing, which typically costs between $75 and $200, can help prevent costly repairs by reducing the risk of problems, maintaining efficiency, and prolonging the unit’s lifespan. It’s recommended to schedule professional servicing at least once a year to keep your air conditioner in top condition.
