Why Is My AC Unit Leaking?

From clogged drains to refrigerant problems, the short answer is that AC units leak when something in the system is not working properly. This leaking AC issue can lead to costly repairs or water damage if ignored. At American Cool and Heat, we provide professional service to identify why your system is leaking and restore it to proper working condition. Our licensed technicians are here to deliver reliable AC repair Burbank residents (and others throughout the area) can count on.

Leaking AC

Common Causes of a Leaking AC Unit our AC Repair Burbank Pros Have Fixed 

Several issues can cause your AC to leak water, and each one requires a professional diagnosis to prevent further complications.

Clogged Condensate Drain Line

One of the most frequent reasons for a leaking AC is a clogged drain line. Over time, dust, dirt, and even mold can build up in the line, blocking the flow of condensation out of your system. When the line is blocked, the water backs up and eventually spills out of the unit.

Our technicians use professional-grade equipment to clear drain lines safely, restoring proper drainage. We also offer maintenance services that keep the lines clean to reduce the risk of future leaks.

Frozen Evaporator Coils

When airflow is restricted or refrigerant levels drop too low, the evaporator coil may freeze. Once it starts to thaw, the excess water can overwhelm the drain pan and leak onto your floors.

We address this issue by identifying why the coil is freezing in the first place. It could be due to dirty filters, blocked ducts, or a refrigerant leak. By fixing the underlying cause, we prevent the cycle of freezing and leaking from recurring.

Damaged or Overflowing Drain Pan

Every AC system has a drain pan to catch condensation, but over the years, these pans can rust, crack, or simply overflow if not emptied properly. A damaged drain pan can no longer hold the water, leading to visible leaks.

Our team inspects and replaces worn or damaged pans with durable parts designed for your specific system. Regular inspections during maintenance visits also allow us to spot early signs of wear before the pan fails completely.

Low Refrigerant Levels

Refrigerant is critical to your system’s cooling process. When levels are low, your AC has to work harder, and the coil is more likely to freeze. As mentioned above, once that ice melts, leaking often follows.

We provide safe refrigerant recharging as part of our repair service. More importantly, we locate and fix the source of the leak, ensuring your system operates efficiently without recurring problems.

Improper Installation

If your air conditioning unit was installed incorrectly, leaks may appear almost immediately. An improperly leveled system or poorly connected drain lines can create conditions where water doesn’t drain as it should.

Our installation experts ensure every unit is set up to manufacturer specifications. If you suspect poor installation is behind your leaking AC, we can evaluate the system and make the necessary corrections.

How Our Team Fixes Leaks Safely and Efficiently

When you call us for AC repair in Burbank and the nearby area, we start with a thorough inspection. Our process ensures we not only stop the visible leak but also fix the underlying issue to keep your home safe and comfortable.

  • We check air filters and airflow to rule out restrictions. 
  • We inspect refrigerant levels and test for leaks. 
  • We examine drain lines, pans, and pumps for blockages or damage. 
  • We evaluate the evaporator coil for freezing or corrosion. 
  • We confirm the system is properly leveled and draining. 

That list is by no means extensive. By addressing the full system, we prevent repeated leaks and help your AC run at peak efficiency.

Risks of Trying to Fix a Leaking AC on Your Own

It can be tempting to grab a wrench or drain cleaner and try to stop the leak yourself, but this often creates more problems than it solves.

  • Using harsh chemicals to clear a clogged drain line can corrode the system. 
  • Attempting to refill refrigerant without proper training is dangerous and illegal. 
  • Opening the unit without the right tools can damage delicate parts like the coil. 
  • DIY repairs can void warranties, leaving you with higher out-of-pocket costs later. 

Our professional technicians are trained to resolve leaks safely. We use the right tools, parts, and repair methods to restore your system without guesswork or unnecessary risks. SoCal is no place for substandard AC, as heat can be a real threat. 

Why Amateur Repairs Can Cost You More

Some homeowners turn to unlicensed workers in search of a quick fix. Unfortunately, this approach often leads to bigger bills down the line.

  • Poor workmanship may temporarily stop a leak but fail to resolve the underlying issue. 
  • Inexperienced repairers may use incorrect replacement parts. 
  • Uninsured workers can leave you liable if damage or injury occurs during the job. 

With our licensed, insured, and experienced team, you get reliable repairs backed by a guarantee. We make sure the leak is fully resolved and your AC is working as efficiently as possible.

Preventative Maintenance to Avoid Leaks

The best way to avoid a leaking AC unit is to keep up with routine maintenance. Our maintenance service is designed to catch small issues before they lead to water damage or costly breakdowns.

During maintenance visits, we:

  • Clean drain lines to prevent clogs. 
  • Inspect and replace filters to maintain airflow. 
  • Check refrigerant levels and test for leaks. 
  • Examine coils for signs of freezing or corrosion. 
  • Inspect drain pans for cracks or rust. 

By keeping your system clean and well-maintained, we reduce the chance of leaks and extend the life of your unit.

Steps You Can Take to Reduce Risk at Home

While professional care is essential, there are small steps you can take to support the health of your AC unit.

  • Replace air filters regularly to keep airflow steady. 
  • Keep the area around the indoor unit clear to ensure proper ventilation. 
  • Check for visible water near the unit and call us at the first sign of a leak. 
  • Schedule routine professional maintenance to stay ahead of potential issues. 

These simple steps, paired with our professional care, go a long way toward keeping your AC leak-free and efficient.
