AHU & Air Handling Unit Service in Jakarta
The AHU is a building's lungs: every breath the occupants take passes through its coils, filters and fans. After 12 years as an HVAC engineer I still regularly find AHUs whose filters have not been changed in over a year — airflow down 30%, stuffy floors, and compressors working far harder than they should.
We service AHUs and FCUs in office towers, malls, hotels, hospitals and production areas: from routine maintenance to coil replacement and VSD retrofits. On every visit we measure actual airflow (CFM) and filter pressure drop — not just "it has been cleaned" — because numbers are the only proof an AHU is back at design performance.
Scope of work
- Routine maintenance — chemical coil cleaning, filter replacement (pre, medium, HEPA), blower and drain-pan cleaning.
- Mechanical & electrical repair — fan bearings, belts, motors, contactors, temperature sensors and damper actuators.
- Air balancing — measuring and adjusting CFM per zone to restore design air distribution.
- Coil replacement — replacement coils fabricated to the old unit's dimensions and BTU capacity.
- Energy retrofits — VSD/inverter installation, IE3 motor upgrades, casing insulation repair.
Cost estimate
Baseline rates for AHU work in Jakarta, 2026:
- Routine AHU service (chemical coil clean + filters + mechanical checks) — from IDR 1.8 million/unit.
- Building maintenance contract (AHU + FCU) — from IDR 3.5 million/month depending on unit count.
- Coil replacement — typically IDR 15–60 million depending on dimensions and rows.
- VSD installation — from IDR 8 million/unit including programming.
A written BoQ is free after the survey.
How we work
The workflow is identical on every project, from a shop-house to a factory — so you always know exactly where things stand:
- Site survey (free) — we visit, measure the area, check installation routes, electrical capacity and structure. In factories we also note the production processes that drive heat loads.
- BoQ & working drawings — within 2–5 working days you receive a written bill of quantity, material specifications and drawings. The price we quote is the price we invoice.
- Installation — K3- and BNSP-certified crews work to the agreed schedule, including nights and weekends when production cannot stop.
- Testing & commissioning — airflow, temperature and electrical readings are documented in a commissioning report, followed by handover with a written 12-month warranty.
AHU servicing is most efficient bundled into one contract with the chillers and cooling towers — one team, one logsheet, one party responsible for the whole plant room. We serve buildings across Central and South Jakarta and all of Greater Jakarta; for new air-side systems see ducting installation.
