Case Study: Restoring Efficiency with Air Source Heat Pump Service

Service: Air Source Heat Pump Servicing

 

The Challenge: Air Source Heat Pump Performance Issues

The client contacted our team after noticing reduced performance from their air source heat pump system. During a scheduled air source heat pump servicing visit, our engineers identified several critical issues that were impacting efficiency and system longevity.

Key findings included:

• Heavily clogged condenser coil – covered in dirt, debris, algae, and mould, restricting airflow and reducing heating performance.
• Unit not level – a 20mm lean to the right, likely caused by an uneven or sinking concrete base.
• Water pooling inside the casing – caused by blocked condensate holes, resulting in light rusting.
• Poor drainage – staining and moisture accumulation beneath the unit.

Without prompt air source heat pump service, these issues could have caused serious mechanical strain, poor oil return, reduced efficiency, and potential compressor failure. This case study demonstrates the importance of regular maintenance to prevent costly repairs.

 

The Solution: Expert Air Source Heat Pump Servicing

Our team conducted a professional air source heat pump service to restore efficiency and prevent long-term damage.

Step-by-step approach:

1. Thorough Coil Cleaning

• Removed biological growth and debris using a soft brush, coil cleaner, and low-pressure water.
• Improved airflow and heat exchange efficiency.

2. Re-levelling the Unit

• Lifted and re-bedded the base using shims to meet manufacturer tolerances.
• Confirmed slab stability to prevent future tilting or stress on connections.

3. Drainage Enhancement

• Improved surface gradient and added gravel for stability and drainage.
• Ensured water runs away from the unit, reducing corrosion risk.

The work was completed in a single visit, demonstrating the efficiency of our team and the benefits of a proactive air source heat pump maintenance approach. For more information on professional heat pump servicing and to request a quote, visit our Air Source Heat Pump Servicing page.

 

The Outcome: Improved System Performance After Heat Pump Servicing

The system was restored to full operational efficiency following the heat pump service, with several long-term benefits achieved:

• Improved performance: Optimal airflow and heat transfer efficiency restored.
• System longevity: Reduced strain on components and prevention of early wear.
• Enhanced drainage: No further pooling or corrosion risk beneath the unit.
• Customer satisfaction: The client was pleased with the rapid and professional resolution.

We also recommended ongoing preventative measures, including:

• Schedule annual air source heat pump servicing for consistent performance.
• Install an anti-freeze valve to improve system efficiency and reduce glycol use.
• Replace two weeping AAVs to maintain reliability.
