How Air Conditioners Work

Air conditioning systems are essential for maintaining comfortable indoor temperatures, especially in places like Air Conditioning Nowra, NSW, where hot summers demand reliable cooling. 

However, one of the common issues faced by homeowners and businesses is water leakage from air conditioning units. 

If you’re dealing with this issue, it’s essential to understand the causes and solutions to prevent further damage to your building.

How Air Conditioners Work

Before diving into the reasons behind water leakage, it’s helpful to understand how air conditioners function. Systems like split-system air conditioners work by removing humidity from the air. 

This process results in condensation, which is collected and drained away through a condensate drain line. When this process encounters a fault, water may begin leaking.

Common Causes of Air Conditioning Leaks

Clogged Drain Line

One of the most frequent reasons for water leaks is a clogged drain line. Dirt, debris, or mould can block the drainpipe, causing water to back up and overflow. This is particularly common in humid areas like Nowra, NSW, where moisture levels are naturally higher.

Dirty Air Filters

If your air filter is clogged with dust and debris, it can restrict airflow. This leads to the evaporator coil freezing, and when the ice melts, it can cause excess water to overflow, leading to leakage.

Improper Installation

Incorrect installation, especially of split system units, can result in improper drainage. If the unit is not level, water may pool and leak instead of draining properly.

Low Refrigerant Levels

When refrigerant levels are low, the pressure in your system drops, causing the evaporator coil to freeze. As the ice thaws, it may produce more water than the system can handle.

Damaged or Rusted Drain Pan

Over time, the drain pan, which collects condensation, can become corroded or cracked. This leads to water leaking from the air conditioning unit.

Blocked Condensate Pump

In some systems, a pump is used to remove condensation. If the pump malfunctions or becomes blocked, it can cause water to overflow.

Preventing Water Leaks in Air Conditioning Units

To avoid water leaks and keep your air conditioning system in Nowra functioning efficiently, consider the following tips:

Regular Maintenance

Schedule routine servicing for your air conditioner to clean filters, check refrigerant levels and inspect the condensate drain line.

Replace Air Filters

Ensure air filters are replaced every few months, especially in high-use seasons.

Check Drain Lines

Inspect and clean the condensate drain line to prevent blockages.

Ensure Proper Installation

Work with professional HVAC technicians in Nowra, NSW, to ensure your air conditioner is installed correctly.

Inspect the Drain Pan

Regularly check the condition of the drain pan for any cracks or rust.

When to Call a Professional

While some minor issues like cleaning the drain line or replacing filters can be handled on your own, certain problems require professional assistance. For example, if you notice persistent water leaks despite your efforts, it may indicate a deeper issue, such as a refrigerant leak or damaged components.
