AC unit leaking water

Why is your A/C unit leaking water?

Why is your A/C unit leaking water? The first thing you should do when you notice that your A/C unit is leaking, is to shut off your system. This will prevent any further damage to your home. There are quite a few reasons why your unit may be leaking water. The most important thing to keep in mind is that these issues need to be looked at by certified professionals, so you can make sure to avoid any costly damages in the future.

Why is your A/C unit leaking water?

Dirty Air Filter-

A dirty air filter is one of the most common reasons for leaks. An unclean air filter blocks the airflow to the evaporator coil. If that happens the coil will get too cold, then freeze over. Once it melts, it drips an excessive amount of water that the pan may not be able to contain. It is recommended to change your air filter every 1-3 months depending on the season.

Rusted or Damaged Drain Pan-

This issue may arise in combination with damage caused by a dirty air filter. Your drain pan is susceptible to rust and can be damaged by excessive amounts of water. If your unit is on the older side, around 10-15 years, it may be time for a replacement.

Broken Condensate Pump-

If your furnace or A/C unit is stored in the attic or basement, it will have a condensate pump that pumps the water outside of your home. If this component of your unit breaks or malfunctions, it means that the water may not be pumped outside efficiently, or at all.

Clogged Condensate Drain Line-

Your drain is the most essential part of your A/C unit. These drain lines can become clogged with dirt, dust, sludge or mold. If it becomes clogged then the condensation will back up into your home. There are methods to try and fix the clog before having to replace the entire drain line, this includes using a wet/dry vac to remove the blockage. But the most surefire way to ensure a successful removal, is to hire a certified professional so they can use their equipment to remove the clog.

Low Refrigerant-

A unit that is low on refrigerant, will lower the pressure on the entire system. This causes the evaporator coil to freeze over and perform similar to when it has a dirty air filter. Signs that your A/C unit is low on refrigerant could be that your unit is not cooling like it should, or you hear a distinct hissing noise from your unit. Depending on the severity of the refrigerant leak, it could make the difference between repairing or replacing the entire unit.

It is important to take A/C unit leaks seriously. Water can do a lot of damage to your home, inside and out. A certified professional like those at AGES Services can help you maintain your home and retain its value for years to come.
