Quick Fixes for Common Condensate Drain Problems in Central A/Cs

Quick Fixes for Common Condensate Drain Problems in Central A/CsYour home’s cooling system produces gallons of condensate every day, so it’s not unexpected that problems can crop up with its drainage system from time to time. An experienced HVAC contractor can quickly fix the condensate drain problems in central A/Cs that might develop, including these common ones:

  • Algae blockages. If an algae overgrowth clogs the drain lines, backed up condensate can overflow and cause serious water damage in your home. To prevent this, your HVAC contractor can ensure that the collector pans and drain lines are in good condition and clean the lines periodically to keep algae under control.
  • Mold growth. A warm, moist A/C drain system is the ideal environment for mold growth. Once it gets established, mold can enter the ducting and degrade your indoor air quality. It can also infiltrate the evaporator coil and slowly strangle vital system airflow. If you notice signs of mold, have your HVAC pro inspect the system to find the source and have it dealt with promptly.
  • Frozen evaporator coil. If your cooling system quits working unexpectedly, and you see puddles of water underneath the unit, the coil has likely iced up. To correct the most frequent cause of icing, your HVAC specialist needs to adjust the airflow rate over the cooling coil.
  • Drain trap issues. The drain line on your A/C has a U-shaped trap that works similar to the trap on a bathroom or kitchen sink to prevent sewer gas backups. If you’re getting bad odors from your HVAC vents, you have a dry drain trap and your HVAC pro can pinpoint and fix the cause.
  • System shutdowns. Some drainage systems include a sensor inside the sealed air handler unit to detect backed up condensate and shut down the air conditioner before an overflow occurs. Once it’s triggered, your HVAC technician will need to access the compartment, clean out the pan and unclog the drain line to get your cooling system up and running again.
