Oxy Air tips and trick on how to fix leak in air conditioning unit?

An efficient and properly functioning HVAC system is essential for maintaining a comfortable indoor environment. However, if you’ve noticed water dripping from the indoor unit of your heat pump, it’s time to address this issue promptly. This common problem can be attributed to a lack of maintenance, emphasising the importance of regular servicing. In this blog, we’ll explore why water may be dripping from your indoor unit, the significance of proper maintenance, and how annual servicing can help prevent this issue from occurring.

Tip 1 – Understanding the Water-Dripping in Your Heat Pump

When water starts dripping from your heat pump’s indoor unit, it’s typically an indication of an underlying problem. The most common reasons for this issue are:

Tip 2 – Clogged or Dirty Filters: Over time, dust, dirt, and debris can accumulate in your heat pump’s filters. When these filters become clogged, they restrict airflow, causing the evaporator coil to freeze and subsequently thaw, leading to water leakage.

Tip 3 – Drain Line Blockages: Inside your heat pump, there’s a drain line that carries condensate (water) away from the unit. If this drain line becomes blocked, water can back up and overflow, causing it to drip from the indoor unit.

Tip 5 – Excessive Moisture: In some cases, especially in high-humidity environments, a heat pump may produce more condensate than usual. This can overwhelm the system’s drainage capacity, leading to water leakage.



Preventing water leakage from your heat pump’s indoor unit begins with regular maintenance. Here are several reasons why maintenance is essential:

Efficiency: Properly maintained heat pumps operate more efficiently, reducing energy consumption and potentially lowering your utility bills.

Longevity: Regular maintenance extends the lifespan of your heat pump, protecting your investment and avoiding premature replacement costs.

Indoor Air Quality: Clean filters and coils contribute to better indoor air quality by reducing the circulation of dust and allergens.

Reliability: Regular servicing helps prevent unexpected breakdowns, ensuring that your heat pump is always ready to keep your home comfortable.

Safety: Routine maintenance also includes checking for any potential safety hazards, providing peace of mind for you and your family.

Annual Servicing: How to fix water dripping from the heat pump/air conditioning unit?

Annual servicing is an integral part of keeping your heat pump in top condition and preventing issues like water dripping from the indoor unit. Here’s what you can expect during a typical annual service:

Filter Cleaning or Replacement: The technician will clean or replace the filters, ensuring unrestricted airflow and preventing the evaporator coil from freezing.

Coil Cleaning: The evaporator and condenser coils will be inspected and cleaned as needed to maximise heat exchange efficiency.

Drain Line Inspection: The technician will inspect the drain line for any blockages and ensure proper drainage.

Lubrication: Moving parts may be lubricated to reduce friction and extend their lifespan.

Refrigerant Check: The refrigerant levels will be checked to ensure they are at the right levels for optimal performance.

Overall System Check: The technician will perform a comprehensive inspection of the entire system to identify and address any potential issues.

Service Costs

Annual servicing is an additional service that is well worth the investment in maintaining the efficiency and reliability of your heat pump. The cost for this service can vary depending on the type of heat pump system you have:

Hi Wall System: For Hi Wall systems, the cost for an annual service is $195.00. This fee includes the benefits of cleaner air, energy savings, and a system that runs smoothly.

Ducted System: Ducted systems, being more complex, require a more thorough service. Therefore, the cost for an annual service for a ducted system is $350.00. This fee covers the comprehensive maintenance required to keep your ducted system in excellent condition.

Prevention is the best protection

Water dripping from the indoor unit of your heat pump is a clear sign that maintenance is overdue. To prevent this issue and ensure the efficient operation of your HVAC system, annual servicing is highly recommended. Regular maintenance not only helps extend the life of your system but also contributes to energy efficiency, indoor air quality, and the overall comfort of your home. So, don’t wait for problems to arise – invest in annual servicing to keep your heat pump running smoothly and prevent the inconvenience of water leakage.
