Aircon Inspection & Performance Testing: Best at $100
Only $100 for Aircon Inspection & Performance Test
System Analysis $100
Recommended for air conditioners that are not cooling effectively without a clear indication of the cause. This service includes a report and proposals to resolve the issues.
1. Initial Assessment
- System Inventory: Document the make, model, age, and specifications of the existing AC units.
- Client Consultation: Discuss any specific concerns, performance issues, or objectives with the homeowner.
2. Physical Inspection
- Indoor and Outdoor Units: Check for physical damage, signs of wear, and cleanliness.
- Air Filters: Inspect for dirt and clogs that impair airflow and reduce efficiency.
- Evaporator and Condenser Coils: Look for dirt buildup and damage.
- Drainage Systems: Ensure there is no blockage or leakage in the drainage pipes.
- Electrical Connections: Check for loose connections, damaged wires, or signs of corrosion.
3. Aircon Performance Testing
- Cooling Efficiency: Measure the temperature drop across the indoor unit to assess cooling performance. This includes checking suction line temperature and pressure, FCU return air and off-coil air temperatures, and superheat value.
- Refrigerant Level: Assess refrigerant levels using the superheat value, which is based on suction pressure and temperature as indicators. For example, a system with clean coils for both indoor and outdoor units that has a superheat value below 4 during a hot day may indicate an overcharged refrigerant system. Conversely, if the suction line pressure falls below 80 psi, it could suggest that the refrigerant is undercharged.
- Electrical Load Testing: Measure the electrical consumption of the AC units to assess their efficiency.
4. Environmental Assessment
- Room Size and Layout: Evaluate if the AC unit’s capacity is appropriate for the space it serves.
- Ambient Conditions: Consider the typical and extreme ambient conditions that the system has to operate under in Singapore’s climate.
5. Maintenance Review
- Maintenance History: Review past maintenance records to identify recurring issues or neglected maintenance.
- Best Practices: Recommend a maintenance schedule based on manufacturer’s guidelines and industry best practices.
6. Reporting
- Findings and Recommendations: Compile a detailed report outlining the current condition of the AC system, performance issues identified, and recommendations for improvements or repairs.
- Energy Efficiency Tips: Provide tips on how to operate the AC system more efficiently, including thermostat settings, usage patterns, and routine maintenance tasks.
