Common Causes Behind an Air Conditioner Leak

Aug 11, 2022 | HVAC

Although routine maintenance by a professional cooling and heating installation technician ensures your air conditioner runs smoothly, it can run into problems that hinder its performance. One example is a water leak directly from the system, which can lead to water stains and puddles beneath it. This can be caused by several problems, including: 

Air Conditioner Leak

Faulty Drain Pump

This type of problem can often be confused with a clogged drain line. However, this component pulls water from the overflow pan. If this isn’t working the way it should, the water overflows and drips directly from the air conditioning unit. This problem can only be addressed by a professional technician.

Clogged Drain Line

If you hired an air conditioning services professional and they determined that the drain pump is working properly, the issue is elsewhere. It is likely that the leak may be coming from a clogged drain line. When this happens, water cannot escape and will get backed up, causing the condensation to come back inside and leak inside your home. This can sometimes be remedied with a simple wet/dry vacuum, but if it doesn’t work, let the technician take care of the issue.

Cracked Overflow Pan

The overflow pan can sometimes take damage, which can cause a crack along the bottom. This issue is fixed with a specialized tape or adhesive to stop the leaking. But this is only a temporary solution, and depending on the damage, a full replacement may be better in the long run.

Low Refrigerant

A low refrigerant charge can affect the pressure inside the AC unit. This causes the evaporator coil to freeze, which then results in leaks. Other signs of low refrigerant include hissing or bubbling sounds. Get in touch with your local technician as soon as possible to prevent your AC from getting damaged further.
