How Often Should You Service Your AC in Dhaka?
Ask ten AC owners in Dhaka when they last had their unit serviced and you’ll get ten different answers — most of them overdue. Servicing an air conditioner is one of those maintenance tasks that’s easy to postpone, especially when the AC seems to be “working fine.” But in Dhaka’s climate, skipping regular maintenance means paying more in electricity, facing avoidable breakdowns, and shortening the lifespan of an appliance that costs serious money to replace.
This guide by Reliable AC Service Ltd. gives you a clear, practical servicing schedule built around Dhaka’s actual weather, air quality, and usage patterns — not generic advice written for temperate climates.

Why Dhaka Demands More Frequent AC Servicing
Service recommendations from AC manufacturers are written for average conditions — moderate dust, clean air, and seasonal use. Dhaka is anything but average when it comes to conditions that wear down air conditioners:
- Year-round high humidity — averaging 70–90% relative humidity, which accelerates mould growth inside units and on evaporator coils
- Severe air pollution — Dhaka consistently ranks among the world’s most polluted cities; filters clog in weeks rather than months
- Extreme summer heat — temperatures regularly exceed 38–40°C from April to September, pushing ACs to run near maximum capacity for months
- Voltage fluctuations — inconsistent power supply stresses electrical components and capacitors
- Construction dust — ongoing construction across Dhaka generates fine particulate matter that infiltrates outdoor condenser units
These factors combined mean that service intervals suitable for, say, a temperate European city simply don’t apply here. What should be serviced every six months in a clean environment may need attention every two or three months in Dhaka.
The Recommended AC Service Schedule for Dhaka
wks
Every 2–4 Weeks — Filter Cleaning
Remove and rinse the air filter under running water. In heavy-use periods (April–September) or if your home is near a main road, aim for every two weeks. A clogged filter is the leading cause of poor cooling and high electricity bills in Dhaka households.
mo
Every 3 Months — Basic Professional Service
A qualified technician should clean the indoor coil, flush the drain line, check refrigerant pressure, inspect electrical connections, and clean the outdoor condenser. This is the core maintenance interval for heavy Dhaka use.
mo
Every 6 Months — Deep Service
Full chemical wash of both indoor and outdoor coils, drain pan deep clean, blower wheel cleaning, refrigerant top-up if needed, full electrical inspection, and lubrication of moving parts. Recommended before summer (March) and again after monsoon (October).
yr
Annually — Full Inspection & Gas Check
Complete system health check including compressor performance, refrigerant level measurement, all electrical components, thermostat calibration, and condensate system. Ideal in March before peak summer hits.
Best timing: Book your annual or 6-month service in March, before summer. Technicians are busy from May–August and response times can be longer. Getting serviced early also ensures maximum efficiency when you need cooling most.
What Each AC Service Should Cover
Not all “AC services” are equal. When you book professional AC cleaning in Dhaka, make sure the service includes the following:

Frequently Asked Questions
For Dhaka’s climate, a basic professional service every 3 months is recommended during heavy use, with a full deep-clean service every 6 months. Air filters should be cleaned at home every 2–4 weeks.
Neglected ACs consume significantly more electricity, cool less effectively, are prone to breakdowns, develop mould that degrades indoor air quality, and have a shorter overall lifespan. In Dhaka’s conditions, skipping two or three service cycles can visibly impact performance.
You can clean the air filter yourself — it’s easy and takes about 10 minutes. However, cleaning the evaporator and condenser coils, flushing the drain line, and checking refrigerant levels requires professional tools and training. Attempting these without proper knowledge can damage the unit.
March (before summer) and October (after monsoon) are the ideal times for major service. Booking in March ensures your AC runs efficiently through the peak April–September heat. October servicing removes monsoon mould and prepares the unit for year-round use.
Yes, significantly. A dirty evaporator coil alone can increase energy consumption by 15–20%. When the entire system is clean and refrigerant levels are correct, the compressor doesn’t have to work as hard, directly reducing electricity use.
