Carrier AC Water Leak Repair – Clogged Condensate Drain Line

A homeowner contacted us after noticing water leaking from their air conditioning system. By the time our technician arrived, water had already begun leaking through the first-floor ceiling.

After a complete HVAC inspection, we identified the source of the problem—a clogged condensate drain line. When the drain becomes blocked, condensation cannot exit the system properly. Instead, the drain pan overflows, allowing water to leak into the home and potentially cause significant property damage.

We also found that the system was not equipped with a condensate overflow safety switch (float switch). This inexpensive safety device automatically shuts down the air conditioner if the drain line becomes clogged, helping prevent water leaks and unnecessary repairs.

Work Performed

  • Complete HVAC system diagnostic
  • Cleared the clogged condensate drain line
  • Verified and restored proper condensate drainage
  • Tested system operation
  • Recommended installing a condensate overflow safety switch (Float Switch)

The repair was completed quickly, and the total cost to the homeowner was less than $200. Regular HVAC maintenance and routine drain line cleaning help prevent unexpected water leaks, protect your home, and keep your air conditioning system operating efficiently.
