Helpful HVAC Maintenance Tips To Know if Your System Is Leaking Water

June 29, 2023

Have you ever walked outside and found the condenser unit of your AC system leaking water? Maybe you have seen a puddle of water accumulate indoors after your AC runs for an extended period – in either case, if your air conditioning system is leaking water, it’s important to schedule a visit from an air conditioning repair professional immediately.

Is Water Leaking From My AC Normal?

Typically, you can expect some water to leak from your air conditioning system. However, it is crucial to understand the difference between a normal amount of water and when your air conditioning may be leaking too much. In this guide, we’ll detail reasons why your air conditioner could be leaking in excessive amounts. Keep reading to learn why your air conditioner is leaking water and when to call an HVAC maintenance expert to help keep your Temecula-area home cool and comfortable. 

Reasons Your AC Could Be Leaking Water

The following are examples of issues that can be the cause of your HVAC system leaking water:

  • A clogged condensate drain can be the culprit. From time to time, your condensate drain can become partially or completely clogged from a buildup of dirt, rust, algae and other debris.
  • Check if your drain line is disconnected. If your air conditioner was not properly installed, the drain line can loosen over time and cause the pipe to detach from its connection. Similar to when your condensate drain is clogged, a disconnected drain line could be the cause of your air conditioner leak.
  • AC running in cold temperatures could cause a leak. In Murrieta and surrounding areas, it can be easy to let your air conditioning keep running after it’s necessary. If your HVAC unit is attempting to cool your home when the outdoor temperatures drop below 60 degrees Fahrenheit, the cooling coils can freeze and cause your air conditioner to start leaking water.
  • The condensate drain may be cracked. Over time, the condensate pan in your HVAC unit can rust and crack. When this happens, the drain pan is no longer sealed and could cause water to leak from your AC system. 
  • You have dirty filters in your AC unit that need to be replaced. A dirty air filter will restrict airflow over the evaporator coils. As a result, the coils get too cold and freeze over. When they melt, the extra moisture will drip into the condensate pan, causing it to overflow. 
  • Your refrigerant levels may be low. Similar to a dirty air filter, low refrigerant levels may result in a lower amount of pressure in your HVAC unit. This may cause your evaporator cables to freeze. When this happens, it can cause the drain pan to overflow and leak water. 

How Much Water Leaking From My AC Unit Is Too Much?

During operation, your AC unit may produce very minimal amounts of condensation. The amount of condensation that is produced, however, may depend on various factors, most importantly the thermostat setting and the outside temperature.
