AC Problems We Fix
The most common air conditioner faults, diagnosed and repaired on site across Kathmandu homes.
Not cooling properly
Weak airflow or room-temperature air despite setting the remote to 18°C. We test compressor amperage and thermistor sensors on arrival.
Water dripping indoors
Choked condensate drain tubes, cracked internal water trays, or iced evaporator coils melting rapidly inside your living room.
Gas leakage detection
Micro-fractures in copper flare nuts, service valves, or rusted outdoor coils. We locate leaks with electronic detectors and nitrogen testing.
Outdoor unit not starting
The indoor unit runs but the outdoor compressor stays silent, usually a blown dual-run capacitor, faulty contactor, or inverter communication error.
Loud rattling or humming
Harsh vibration from unaligned blower wheel drums, degraded motor shaft bearings, or broken outdoor compressor dampening pads.
Bad odour when switched on
Musty or vinegar-like smells from mould colonies and bacterial spores inside clogged aluminium fins and stagnant drain pan reservoirs.
Remote not responding
The AC refuses to switch on or change modes despite good batteries, traced to a scorched infrared receiver board or burned power PCB.
Tripping the MCB repeatedly
The breaker trips the instant the AC powers on, evidence of a compressor grounding short, seized fan windings, or stripped insulation.
Ice forming on the coil
Frost across the front evaporator blades, caused by badly restricted airflow through blocked mesh filters or low suction refrigerant pressure.

Why People in Kathmandu Call Us First
We built our reputation on doing air conditioning repairs the right way, avoiding temporary quick fixes that leave you stranded in peak summer.
8+ years on air conditioning
Master mechanics specialising in multi-brand inverter PCBs, DC fan motors, and rotary compressors, with continuous factory training.
Leak test before every gas refill
We never dump gas into a leaking system. We pressurise with nitrogen, seal brass flare joints, vacuum out moisture, then refill to exact factory gram specs.
Covers so your wall & floor stay clean
Custom waterproof catchment bags route dirty high-pressure water straight into drain buckets, never over your paint or flooring.
Fixed price agreed before work
No mystery charges or post-service surprises. You approve the exact cost of parts and labour in writing before we open a cabinet panel.
