As the summer heat intensifies in Philadelphia, ensuring your HVAC system is in top condition becomes crucial. Water leaks from your HVAC unit during these hot months can be a common yet perplexing issue. This post will guide you through troubleshooting and repairing water leaks to keep your home comfortable and your system running efficiently.

Understanding the Cause

Water leaks in HVAC units are primarily due to condensation. As humid air passes over the cold evaporator coil, moisture from the air condenses on the coil and drips into a drain pan, exiting through a condensate drain line. Problems arise when this flow is interrupted or when components fail.

Troubleshooting Steps

  1. Check the Air Filter: A dirty air filter restricts airflow, causing the evaporator coil to freeze and then thaw, leading to excessive water. Replace your filter regularly, especially during peak usage in summer.
  2. Inspect the Condensate Drain Line: Ensure it's not clogged. A simple way to clear minor clogs is by using a wet/dry vacuum to suck out debris from the outdoor end of the line.
  3. Examine the Drain Pan: Older pans may crack or rust, leading to leaks. If you spot damage, replacing the pan is necessary.
  4. Look at the Evaporator Coil: A dirty coil can cause freezing and subsequent thawing, much like a dirty air filter. Cleaning the coil might require professional help, especially if it's heavily soiled.
  5. Check for Proper Installation: Sometimes, issues arise from improper installation, causing uneven drainage or leaks. If you suspect this is the case, consulting with a professional is advisable.
