I saw in my field work (personal and commercial use) nearly 70 percent of AC problems are related to poor maintenance rather than major component failure or damage.
How to Choose the Best AC Mechanic nearby You
At first, you have to prefer an AC mechanic who properly checks the problem, explains it clearly, and tests both the electrical parts and cooling systems before repair. Many people select the cheapest technician or mechanic for low cost, without proper diagnosis can damage the compressor or major parts later.
Important Things to Check
1. Experience or Expert with Different Types of AC
An experienced AC mechanic should understand:
- Wall Mounted Split AC
- Inverter AC
- Cassette AC
- Ceiling AC
- VRF systems
- Commercial HVAC.
- Chiller AC.
Now, there are modern and advanced inverter technology Air conditioners for personal and commercial use. So, here are needs to expert and knowledgeable AC mechanic for solve cooling problems.
2. Use of Professional Instruments
A qualified or trained AC mechanic should use:

So, you have to select an advanced knowledgeable AC mechanic for personal and commercial AC problems solution.
Common AC Problems Diagnosed by Nearby AC Mechanics
AC Running but Not Cooling
One of the most common problems in Bangladesh during summer season is ac running but not cooling, it happens when you’re low refrigerant, cooling pipe leak, the coils, weak airflow, sensor fault, or compressor problems.
Technical Causes
| Problem | System Effect |
| Dirty evaporator coil | Reduces heat absorption. |
| Low refrigerant | Decreases cooling capacity. |
| Weak capacitor | Compressor struggles to start. |
| Clogged air filter | Restricts airflow. |
| Outdoor unit blockage | High condensing temperature. |
| Cooling Pipe Leak | Repair Leak expertly. |
Your AC cooling cycle becomes less efficient when the pressure and temperature inside the system are not balanced properly.
Why Does an AC Leak Water?
Water leakage is another common simple problem, when the drainage line gets blocked or the evaporator coil freezes. Water condensation is normal during cooling, but if the drainage system does not work properly, water can overflow inside the room.
Main Reasons
- Blocked drain pipe.
- Frozen evaporator coil.
- Improper AC installation slope.
- Dirty air filter.
- Low refrigerant pressure.
I saw in my work that around 50 percent of water leakage issues are solved though the properly drain clan and flash. Sometimes indoor unit unlevel reason for water leakage.
Why Does an AC Consume Too Much Electricity?
High electricity bills often happen when your AC works with a heavy load or loses efficiency. Several technical problems can increase power consumption.
| Cause | Impact on Electricity |
| Dirty condenser coil | Compressor works harder. |
| Low refrigerant | Longer cooling cycle. |
| Oversized room load | Continuous compressor run. |
| Poor insulation | Heat gain increases. |
| Incorrect thermostat setting | Higher runtime. |
The cooling load equation used in HVAC engineering is:
Q=mcpΔTQ = m c_p \Delta TQ=mcpΔT
Where:
- Q = Heat load
- m = Mass flow rate
- cₚ = Specific heat capacity
- ΔT = Temperature difference
When your room heats load increases, then your AC requires more energy to maintain comfort.
How AC Mechanics Diagnose Refrigerant Problems
Professional AC mechanics are using the pressure readings, superheat calculations, and temperature measurements to confirm refrigerant issues. Many AC users are assumed that low cooling means low refrigerant, but this is not right all the time.
Diagnostic Process
Pressure Testing
Low suction pressure often indicates the refrigerant undercharge.
Superheat Calculation
Superheat means the determine evaporator performance.
Superheat =T suction line−T evaporator saturation\text {Superheat} = T_{suction\ line} – T_{evaporator\ saturation}Superheat=T suction line−T evaporator saturation
Sub-cooling Measurement
Sub-cooling confirms condenser efficiency.
Leak Detection
Technicians may use:
- Nitrogen pressure testing.
- Soap bubble inspection.
- Electronic leak detector.
According to industry reports, refrigerant leakage can reduce system efficiency by 5 to 20 percent annually if left unchecked.
Importance of AC Load Calculation
Proper load calculation helps you to choose the right capacity or size AC for your room. An AC that is too large or too small can reduce cooling efficiency and increase electricity usage.
Basic Cooling Load Factors
| Parameter | Effect |
| Room area | Determines based on capacity. |
| Sun exposure | Increases heat gain. |
| Occupancy | Adds sensible heat. |
| Electronics | Raises thermal load. |
| Ventilation | Changes cooling demand. |
The commonly used HVAC approximation formula is:
BTU/hr= Area × Cooling Factor BTU/hr = Area \times Cooling\ Factor BTU/hr=Area × Cooling Factor
Poor load calculation is one of the biggest reasons in Bangladesh, behind the high electricity bills and insufficient cooling efficiency.
Real Case Study From Field Experience
Office AC Failure in Dhaka
One customer searched for the best AC Mechanic in Dhaka because three inverter AC units were not cooling properly in her office, then I reached in here within a very short time, and I saw here:
Initial Observation
