Inverter AC Repair in Dhaka — Expert Technicians at Your Door
Your inverter AC deserves more than a general repair touch. Mohammadi Engineering Ltd. sends trained technicians who handle PCB faults, compressor issues, gas leaks, and error codes — all on-site across Dhaka city.
Inverter AC Repair Is Not the Same as Regular AC Repair
Here is the thing most people do not realize — an inverter air conditioner runs on a completely different system than a standard non-inverter unit. The compressor in an inverter AC does not simply turn on and off. It adjusts speed based on cooling demand, and that means the circuit board, inverter module, and sensors are all working harder and in more complex ways.
When something breaks, a general technician who only knows basic AC repair Dhaka methods might misdiagnose the problem. We have seen cases where a simple sensor fault was mistaken for a dead compressor, and the homeowner was quoted 15,000+ BDT for a replacement they never needed.
- Inverter PCB boards require component-level diagnosis, not just swapping parts
- R32 and R410A refrigerants need specific handling and refill equipment
- Error codes differ by brand — a Daikin E1 is not the same as a General E4
- Compressor inverter modules cost more when damaged by wrong repair attempts
- Proper AC servicing Dhaka for inverter units includes PCB cleaning and sensor calibration
Inverter AC Problems We Fix Every Day in Dhaka
These are the issues our technicians encounter most frequently. If your inverter AC shows any of these symptoms, do not wait — small problems escalate fast with inverter boards.
PCB / Inverter Board Failure
The most common culprit. Your AC may not turn on at all, or the outdoor unit stops responding. We diagnose at the component level and repair or replace the board.
Compressor Not Starting
The inverter module may fail to signal the compressor, or there could be a gas shortage. We test the module, wiring, and refrigerant levels before recommending a fix.
Error Code on Display
Blinking lights or codes like E1, E4, H6, F3, P1 are your AC telling you exactly what is wrong. Our technicians carry manuals for all major brands to decode and fix them fast.
AC Running But Not Cooling
Could be low refrigerant, a faulty expansion valve, or the inverter module stuck at low speed. We check every possibility instead of jumping to the most expensive one.
High Electricity Bill
A damaged inverter board can force the compressor to run at full speed constantly, which defeats the entire point of owning an inverter AC. We fix the root cause.
Unusual Noise from Unit
Grinding, rattling, or humming sounds usually mean fan motor bearing wear, loose copper pipes, or compressor vibration issues. Left alone, these damage other parts.
Refrigerant Leak
Inverter ACs use R32 or R410A gas. Leaks are tricky to find without the right detection tools. We use electronic leak detectors and then refill following manufacturer specs.
Sensor Malfunction
Temperature sensors, discharge sensors, or coil sensors can give wrong readings, making the AC cool erratically or shut down randomly. Quick fix when caught early.
Complete Inverter AC Repair Services in Dhaka
From diagnosis to full repair, Mohammadi Engineering Ltd. covers every inverter AC issue. We work on all brands and models across Dhaka city.
PCB / Inverter Board Repair
We do component-level diagnosis and repair on inverter boards instead of just replacing the entire board. This saves you significant money. When a board is beyond repair, we source genuine or compatible replacements.
Compressor Diagnosis & Replacement
Inverter compressors are more expensive than standard ones, so we test thoroughly before recommending replacement. If a new compressor is needed, we supply and install it with proper vacuum and AC gas refill Dhaka procedures.
Error Code Diagnosis & Fix
Every brand has its own error code system. Our technicians are trained to read Daikin, General, Panasonic, LG, Samsung, and Midea error codes and apply the correct fix on the spot.
Gas Leak Detection & Refill
We use electronic leak detectors to find micro-leaks that soap-bubble methods miss. After sealing the leak, we refill with the correct refrigerant (R32 or R410A) at proper pressure levels.
Sensor Replacement & Calibration
Faulty sensors cause erratic cooling, random shut-offs, and error codes. We replace damaged sensors and calibrate the new ones to match your AC model’s specifications.
Fan Motor Repair & Replacement
Indoor and outdoor fan motors wear out over time, especially in Dhaka’s dusty conditions. We repair when possible and replace with genuine motors when needed.
Deep Cleaning & Servicing
Inverter ACs need regular cooling system maintenance to keep the PCB and coils clean. Our deep cleaning service covers indoor unit, outdoor unit, filters, and drain lines.

What Our Customers in Dhaka Say
Real feedback from real customers. Read customer reviews on our dedicated reviews page.
My Daikin inverter AC was showing E4 error and two other repair shops could not figure it out. Mohammadi Engineering’s technician found the PCB issue in 20 minutes and fixed it the same day. Running perfectly since then.
Called them at 11 PM when our office AC stopped working. They sent a technician within an hour. The inverter board was the problem and they repaired it on-site. Very professional and the price was fair.
Our General inverter AC was not cooling properly. Another company said the compressor was dead and quoted a huge price. Mohammadi Engineering diagnosed a sensor issue, replaced it, and the AC is running like new. Honest team.
