AIR QUALITY & VENTILATION
Duct Cleaning and Ventilation Service in Kathmandu
Ventilation systems need clean pathways, working fans, suitable filters, balanced airflow, and safe discharge routes. Aircon supports inspection, cleaning, repair, and improvement of ducted HVAC and ventilation systems.
Request Ventilation AssessmentA ventilation assessment identifies restricted airflow, dirty filters, blocked grilles, fan problems, leakage, poor fresh-air delivery, and exhaust issues across the building.
Signs of a ventilation problem
Stale air, odour, uneven airflow, noisy fans, dusty grilles, condensation, excess humidity, or poor exhaust can indicate a filter, fan, duct, control, or design issue. The visible symptom may be away from the actual fault.
- Weak or uneven airflow at grilles
- Persistent odour or stale indoor air
- Noisy or vibrating exhaust fan
- Dust around supply or return grilles
- Condensation or humidity concerns
What the service can include
The service scope depends on access and system design. Inspection may include filters, grilles, fans, ducts, dampers, belts, motors, controls, exhaust routes, and fresh-air intake. Cleaning methods should protect the building and the equipment.
- Filter and grille inspection or cleaning
- Fan, motor, belt, and control checks
- Accessible duct and plenum inspection
- Fresh-air and exhaust path review
- Airflow observations and recommendations
Commercial and critical environments
Offices, hotels, restaurants, healthcare spaces, and industrial areas have different ventilation needs. A site-specific plan should consider occupancy, hygiene, heat, moisture, kitchen exhaust, access, and operating schedules.
Service coverage
Our engineering team supports AC systems across Kathmandu, Lalitpur, Bhaktapur and the wider Kathmandu Valley.
Frequently asked questions
How often should commercial ducts be cleaned?
There is no single interval for every building. Frequency depends on dust, occupancy, use, filters, construction activity, moisture, and inspection findings. A maintenance plan should be based on actual condition.
Can duct cleaning fix poor airflow?
It can help when dirt, blocked filters, or accessible restrictions are the cause. Poor airflow can also result from fan, damper, duct sizing, control, or design problems that require further assessment.
Do you service ventilation systems in restaurants and hotels?
We can assess compatible fresh-air, exhaust, and HVAC ventilation requirements for commercial sites, subject to access, system type, safety requirements, and project scope.
