How Often Should You Service Your AC in Dhaka? The Complete 2025 Schedule
Manufacturer service guidelines are based on average conditions. Dhaka’s combination of heat, humidity, and dust puts AC units in a category of their own. Following a generic service schedule here means paying more in electricity bills, experiencing more breakdowns, and replacing equipment earlier than necessary.
This guide lays out the exact service schedule that our technicians at R. K. Refrigeration Works Ltd. — after thousands of home visits across Dhaka since 2017 — have found to make the biggest difference.
The Recommended AC Service Schedule for Dhaka
Every 2–3 Weeks (Summer): Filter Cleaning — DIY
Remove the front panel of your indoor unit, take out the filter, rinse with clean running water, and let it dry before replacing. Takes 10–15 minutes. Skipping this is the single biggest reason ACs lose cooling performance in Dhaka. A clogged filter also forces the compressor to work harder — shortening its life.
March (Before Summer): Full Professional Service — Essential
This is the most important service of the year. A certified technician cleans the evaporator and condenser coils, checks refrigerant pressure, tests electrical connections, clears the drain line, and inspects the compressor. Done in March, it ensures your AC is ready for the heaviest months: April through August.
October (After Monsoon): Second Professional Clean — Highly Recommended
Monsoon season leaves moisture inside AC units. Mold and biofilm build up on the evaporator coil and drain system during July–September. An October service cleans this before the AC sits partially idle through winter, preventing the mold from worsening. Skipping this is fine for light users, but essential for ACs running 8+ hours daily.
Annually: Refrigerant Pressure Check — Professional
Refrigerant pressure should be checked annually even if the AC is cooling well. A slow leak caught early costs a fraction of the damage caused when the compressor runs with low refrigerant. Our technicians use manifold gauges to check this during the March service.
Does the Type of AC Change the Service Frequency?
| AC Type | Filter Clean | Pro Service/Year | Notes |
|---|---|---|---|
| Split AC (Home Use) | Every 2–3 weeks | 1–2 times | Most common in Dhaka homes |
| Split AC (Office/Commercial) | Every 2 weeks | 2–3 times | Higher runtime = more frequent cleaning needed |
| Inverter AC | Every 2–3 weeks | 1–2 times | Inverter tech is efficient but coils still need cleaning |
| Cassette / Ducted AC | Monthly | 2 times | Duct cleaning separately every 2–3 years |
| Window AC (older models) | Every 2 weeks | 1–2 times | Full unit needs cleaning (both coils in one body) |
Signs Your AC Needs Servicing Right Now
Even if you’re on a schedule, these signs mean your AC needs attention regardless of when it was last serviced:
- Cooling feels weaker than a few weeks ago
- Unusual sounds — rattling, hissing, clicking, or grinding from either unit
- Water dripping from the indoor unit (blocked drain)
- Musty or foul smell when the AC runs (mold on the coil)
- Ice forming on the pipe connecting to the outdoor unit
- Electricity bill noticeably higher than same month last year
- AC cycles on and off more frequently than normal
Any of these warrants a call to R. K. Refrigeration Works Ltd. at 01859977692 before the problem worsens. Many of these start as inexpensive fixes and become expensive repairs if ignored for weeks.
March and April are the busiest months for AC service calls across Dhaka. Booking in late February or early March means shorter wait times, earlier morning slots, and the peace of mind that your AC is ready before the heat arrives.
What You Actually Get from Regular AC Servicing
Many homeowners ask whether regular servicing is worth the cost. Here is what years of data from residential and commercial AC maintenance in Dhaka consistently show:
- 15–25% lower electricity bills after a professional coil clean and refrigerant check
- Extends compressor life by several years — the most expensive part of any AC
- Better air quality — dirty coils and drain pans breed mold that circulates through your home
- Fewer emergency repairs — most breakdowns are preceded by months of early warning signs that a service visit would catch
- Manufacturer warranty compliance — most AC warranties require documented regular servicing
A professional AC cleaning service in Dhaka is the most cost-effective maintenance investment you can make for any air conditioning system. For homes with multiple ACs, our team offers combined service visits that cover all units in one appointment.

In Dhaka, the recommended schedule is: clean your AC filter every 2–3 weeks during summer yourself, and have a professional service done at least once a year — ideally in March before summer begins. For heavy users (offices, shops, households using AC 10+ hours daily), a second professional service in October after monsoon season is strongly recommended. Dhaka’s dust and humidity are harder on AC units than most climates.
A full professional AC service from R. K. Refrigeration Works Ltd. includes: filter cleaning, chemical wash of the evaporator coil, condenser coil cleaning, drain pipe clearing, refrigerant pressure check, electrical connection inspection, capacitor and contactor check, and a full performance test. The complete service typically takes 60–90 minutes per AC unit.
AC servicing cost in Dhaka varies by the scope of work. A basic filter clean and general check costs less than a full chemical wash service. At R. K. Refrigeration Works Ltd., we provide transparent pricing with no hidden charges — the exact cost is quoted before any work begins. Call 01859977692 for a quote based on your AC model and the service you need.
You can safely clean the air filter yourself — just remove it, rinse with water, let it dry, and reinsert. Everything else (coil chemical wash, refrigerant check, drain clearing, electrical inspection) should be handled by a trained technician. Attempting coil cleaning without the right chemicals and technique can push dirt deeper into the fins rather than removing it, making the problem worse.
