YORK Air Conditioner Repair: Water Leak Caused by a Clogged Condensate Drain

Our HVAC technicians recently serviced a YORK air conditioner, Model TGLS100C16MP11B, after the homeowners noticed water leaking from the unit. Although the system was still cooling the home, the water leak indicated a problem with the condensate drainage system.

YORK AC Water Leak Diagnosis

During the air conditioner repair inspection, we found that the condensate drain was clogged. As the AC operates, moisture naturally collects on the evaporator coil and must be removed through the condensate drain. When the drain becomes restricted, water can gradually build up and eventually overflow.

One important detail with this type of HVAC problem is that the air conditioner may continue cooling normally. The first visible symptom can simply be a small amount of water around the indoor unit. If the restriction remains, the leak can become worse as the system continues producing condensation.

Condensate Drain Cleaning and AC Repair

Our technician thoroughly cleaned the clogged AC condensate drain line and restored proper drainage. The system was then tested during operation to confirm that condensate was flowing away from the unit correctly and that the air conditioner was operating as expected.

Regular AC maintenance and condensate drain cleaning can help prevent unexpected water leaks and reduce the risk of moisture damage around the air handler. A clogged drain may seem like a minor issue, but leaving it untreated can lead to more expensive repairs.

HVAC Tip: If you notice water around your indoor air conditioning unit, don't ignore it. Even a small leak can indicate a clogged condensate drain. Early diagnosis and professional air conditioner repair can help prevent further damage.
