Why Proper Condensate Management Matters
Condensate traps play a critical role in high-efficiency HVAC systems. Without a functioning trap, negative pressure within the unit can draw unconditioned or contaminated air into the drain line, reducing efficiency and potentially introducing moisture-related issues. Replacing a worn or failed trap kit with a genuine OEM part ensures the system continues to operate as designed.
