AC REPAIR GUIDE
AC Water Leakage Repair in Kathmandu
Water dripping from an indoor AC is usually a drainage, airflow, installation, or condensate-pump problem. Aircon Engineering Solutions diagnoses the source before recommending the right repair for homes, offices, hotels, and commercial spaces.
Book Leakage DiagnosisWe inspect the drain line, drain pan, evaporator coil, filters, insulation, slope, and pump operation. The goal is to stop the leak and address the condition that caused it, not simply wipe away the water.
Common causes of AC water leakage
Blocked condensate drains, dirty filters, frozen evaporator coils, damaged drain pans, poor pipe slope, failed drain pumps, and missing insulation can all cause water to appear around an indoor unit. The correct repair depends on where condensation is escaping.
- Blocked or incorrectly sloped drain pipe
- Dirty filter restricting airflow
- Frozen coil caused by airflow or refrigerant problems
- Cracked drain pan or failed condensate pump
- Loose or poorly insulated drain connections
How our technicians diagnose the problem
A technician checks the indoor unit and drain route, tests water flow, examines coil and filter condition, confirms the unit is level, and checks pump operation where fitted. After clearing or repairing the cause, the system is run through a cooling test to confirm that water is draining correctly.
- Visual inspection and safe isolation
- Drain-flow and pan inspection
- Filter, coil, airflow, and temperature checks
- Pump, slope, insulation, and connection checks
- Cooling-cycle test after repair

Frequently asked questions
Why is my split AC leaking water inside?
The most common causes are a blocked drain, dirty filter, frozen evaporator coil, damaged drain pan, incorrect pipe slope, or condensate-pump fault. An inspection is needed to distinguish between them.
Can I fix an AC water leak by cleaning the filter?
Cleaning the filter may restore airflow when a dirty filter is the cause, but it will not repair a blocked drain, damaged pan, pump fault, or installation issue. Persistent leakage needs a full diagnosis.
Do you repair AC water leakage in Lalitpur and Bhaktapur?
Yes. Our Kathmandu Valley service coverage includes Kathmandu, Lalitpur, and Bhaktapur, subject to technician availability and appointment confirmation.
