4 Reasons Why Your AC is Leaking, and What to Do To Repair It

Summertime means AC time! One of the most important inventions of mankind is the air conditioning system. Even if you live in a tropical country, installing an AC at home can still feel cool and comfortable. But like any other home appliance, it might also experience problems that need immediate fixing. In this case, you should call a professional plumber to help fix your AC problems. 

Why does my AC leaking water? 

One of the most common problems in air conditioning systems is water leaks. If your AC is experiencing water leaks, we have a big problem. Here are the most common reasons why your AC is leaking and how to fix them: 

Air filter problems

One possible reason why your AC has water leaks is because of a dirty filter. Over time, your air filter will accumulate dirt such as dust and pet hair. These could affect airflow into your AC system’s evaporator coil and freeze, in worst cases.

When the condensation melts, it will lead to water leaks. More leaks mean more moisture in your home, leading to mold formation. That is why you should have your air filter changed every 30 to 90 days to prevent water leaks and prolong your AC system’s lifespan. 

Low refrigerant level 

Your AC needs a refrigerant to keep your appliance working and the room cooler. However, a leak can also cause low refrigerant levels. Low refrigerant could freeze the evaporator coil and cause water leaks once the freezing melts. Worse, it could ruin your HVAC system and have to be replaced immediately. 

To prevent matters from getting worst, you should schedule a leak detection from an HVAC expert. A temporary seal is also a good option for low refrigerant until the evaporator coil has already been replaced. 

Rusty drain pan 

If your drain pan is over a decade old, you have to replace it immediately. Drain pans are made of metal which is prone to corrosion and rusting. You can use a sealant to repair small cracks in your drain pan. It is better to replace the drain pan for large holes or cracks. 

Clogged condensate drain line 

A clogged condensate drain can also cause water leaks on your AC. Over time, icky gunk-like dirt and mold can cause clogs. Your nasty clogged drain line could back into your house and cause leaks and floods. Here are the steps you should take to fix your leaky AC unit. 

  • Turn off the AC unit first. 
  • Clean up the water if it has leaked out of the AC unit. Standing water can cause damage to the AC unit. 
  • Identify the cause of the leak. You might have to get down and dirty to determine the cause. 

You can use a wet/dry vacuum to remove the stubborn gunk or a water hose to dislodge the clog. If these methods don’t work, it is best to call a professional plumbing service in Spring Hill, TN, now!
