Home / Services / AC Servicing
A proper service is more than blowing out the filter. We wash the coil and blower wheel, flush the drain, rinse the outdoor unit and check how the system is running — so your AC cools faster, smells fresh and stops dripping.
60–90 min
Typical time for a full split-unit jet wash
The service sheet
Our technicians follow the same written checklist on every unit, and tick it off on your job card. If a step can’t be done — for example, if the outdoor unit can’t be reached safely — we tell you before we start.
01
We run the AC first and note vent temperature, airflow, noise and any error codes.
02
Breaker off, furniture moved or covered, drop sheet laid and the jet-wash bag fitted under the unit.
03
Mesh filters and any carbon or dust filters removed, washed and dried before refitting.
04
Low-pressure water jet through the indoor coil fins to lift packed dust and grime without bending them.
05
The cross-flow fan is where black mould hides. We wash each blade row until the water runs clear.
06
Slime cleared from the tray and the drain line flushed through — the main cure for dripping units.
07
Front panel, swing louvres and casing cleaned so the unit looks as fresh as it smells.
08
Outdoor coil washed from the inside out to clear the road dust, leaves and pigeon feathers that block airflow.
09
Terminal connections tightened, capacitor and running current measured with a clamp meter.
10
Suction pressure checked with a gauge. If it’s low we tell you — we never top up without looking for a leak.
11
Remote, display, swing motor and room sensor tested; weak remote batteries flagged.
12
We run the unit again, compare vent temperature with the start reading and send your job card by SMS.
Choose the right clean
Not every unit needs the deepest clean. Here is how the three service levels compare for a standard 1–1.5 ton wall-mounted split AC.
| Service level | What is cleaned | Best for | Time | Price |
|---|---|---|---|---|
| General service | Filters washed, coil surface brushed and sprayed, drain flushed, outdoor unit rinsed, electrical and gas checks | Units serviced within the last 4 months | 45–60 min | ৳1,200 |
| Jet-wash service | Everything in general service plus full coil and blower wheel jet wash with a drip bag | Most homes — our standard recommendation | 60–90 min | ৳1,800 |
| Chemical coil wash | Jet wash plus a non-acid foaming coil cleaner and anti-bacterial rinse, indoor and outdoor | Musty smells, heavy grime, units not cleaned for a year or more | 90–120 min | ৳2,800 |
| Window AC service | Unit removed from the frame where possible, coils and fan washed, drain holes cleared | Window and through-wall units | 60–90 min | ৳1,000 |
Prices are per indoor unit for 1–1.5 ton splits, valid from August 2026. 2–2.5 ton units add ৳400, and cassette or floor-standing units are quoted on booking. Booking three or more units at the same address? We take ৳100 off each unit.
Outside matters too
Your indoor unit collects heat from the room; the outdoor unit has to throw it away. When the condenser coil is blocked with dust from the road, soot or bird nesting material, the heat has nowhere to go. Pressures rise, the compressor runs hotter and the whole system loses capacity — often right when Dhaka hits 36°C.
On every full service we rinse the condenser from the inside out, straighten any bent fins where possible, check that the fan spins freely and that nothing is blocking the air path. If your outdoor unit sits on an exterior wall with no balcony, tell us when you book so we can bring the right access equipment.
How often?
6 months
Bedrooms used at night. One service before summer, one during the monsoon.
4 months
Living rooms running all day. Three services a year keep the coil clear.
3 months
Offices and shops. Long hours and door traffic bring in more dust.
6–8 weeks
Restaurants and salons. Grease, steam and hair clog filters fast.
Between services
No. We fit a waterproof jet-wash bag under the indoor unit that channels dirty water into a bucket, lay a drop sheet and cover nearby furniture. The wall and floor stay dry, and we take the dirty water away.
Not for a normal jet-wash service. The coil and blower are cleaned in place. Removing the unit is only needed for very heavy contamination or repairs to the coil, and we would quote that separately.
Yes. A dirty unit usually keeps cooling but uses more electricity and struggles on the hottest days. Regular servicing also catches small problems such as a weakening capacitor or a slow gas leak before they become a breakdown.
Only if the pressure reading shows it is low, and only after telling you the likely cause and the price. Refrigerant does not get used up — low gas means a leak, and we recommend finding and repairing it first.
Yes. Inverter units are cleaned the same way, with extra care around the PCB and sensors. We cover the electronics before washing and check error codes after the test run.
Call us within 30 days and we come back free of charge. Occasional drips right after a wash are usually the drain clearing; if it continues we check the drain slope and pipe.
