🌀 What Is an Air Source Heat Pump (ASHP)?
An Air Source Heat Pump (ASHP) is a renewable energy system that captures heat from the air outside and transfers it inside your home to provide heating and hot water. It’s an energy-efficient alternative to traditional boilers or electric heaters and is particularly effective in temperate climates.
ASHPs are widely praised for reducing carbon footprints and lowering energy bills. They’re often used in both residential and commercial buildings and can function year-round—even in temperatures below freezing.
🔧 How Do Air Source Heat Pumps Work?
Air source heat pumps operate on a simple principle: heat transfer. Here’s a quick breakdown:
- Absorption: The system absorbs heat from the outside air into a refrigerant fluid.
- Compression: This fluid is then compressed to increase its temperature.
- Heat Exchange: The heated fluid passes through a heat exchanger, transferring warmth into your home’s heating system.
- Expansion and Recirculation: The fluid cools and circulates back to repeat the cycle.
This continuous loop allows ASHPs to produce more energy than they consume—making them incredibly efficient.
💡 Importance of Regular Heat Pump Servicing
Regular air source heat pump servicing is crucial for performance, lifespan, and efficiency.
✅ Preventative Maintenance Benefits
- Reduces breakdown risk
- Preserves manufacturer warranty
- Extends system life expectancy
⚡ Enhancing Energy Efficiency
Servicing ensures your ASHP runs smoothly, saving you money on energy bills. A well-maintained unit can retain up to 95% of its original efficiency after 15 years.

How to Maintain, Service & Look After Your Air Source Heat Pump
Air source heat pumps (ASHPs) are efficient, eco-friendly alternatives to traditional heating systems. Here’s how you can maintain, service, and look after your air source heat pump to ensure longevity and peak efficiency.
2. Clean or Replace Filters
Dirty filters restrict airflow, making your system work harder and reducing its efficiency. Clean the filters every 1 to 3 months, depending on usage and the manufacturer’s recommendations. If your system has replaceable filters, follow the replacement schedule outlined in your manual.
3. Check System Settings and Thermostat
Make sure your heat pump settings are correct for the season. In colder months, ensure the system is set to heating mode. Periodically test the thermostat to confirm it’s accurately reading room temperatures and communicating properly with your ASHP.
4. Look Out for Warning Signs
If you notice strange noises, reduced heating performance, frozen components, or unexpected spikes in your electricity bill, these may be signs your system needs servicing or repair. Addressing issues early can prevent more serious problems down the line.
5. Schedule Annual Professional Servicing
Even with regular DIY maintenance, it’s essential to have your ASHP serviced by a certified technician at least once a year. They’ll inspect electrical connections, refrigerant levels, moving parts, and system performance to catch issues you may miss.
6. Keep a Maintenance Log
Record every inspection, cleaning, and professional service visit. This helps track the system’s condition over time and may be required to maintain warranty coverage.
🔧 Commissioning of Air Source Heat Pump Systems
Commissioning an air source heat pump (ASHP) system is a critical process that ensures the unit operates efficiently, safely, and in line with the manufacturer’s specifications. This step comes after installation and serves as a final check before the system is fully operational.
The commissioning process involves a comprehensive inspection of the entire ASHP setup, including the outdoor and indoor units, pipework, wiring, and controls. A qualified technician will verify that all components are correctly installed, calibrated, and functioning. They will also ensure that the refrigerant levels are optimal and there are no leaks or electrical faults.
One of the most important aspects of commissioning is system optimization. Technicians assess whether the heat pump settings are aligned with the household’s heating and hot water demands. This includes setting the appropriate flow temperatures, testing defrost cycles, and adjusting thermostats or smart controls for maximum comfort and energy savings.
In addition to hardware checks, documentation is essential. The installer will complete a commissioning checklist, which should be handed over to the property owner. This document includes test results, setup parameters, and any specific recommendations for future maintenance.
Commissioning also includes training the end user. Homeowners should be shown how to operate the system, read the display panel, adjust settings, and identify warning signs of a malfunction. This step improves user confidence and ensures that the ASHP is used correctly from day one.
. It marks the transition from installation to efficient operation and lays the foundation for a long-lasting, high-performing heating system. Skipping this step can lead to poor system performance, higher running costs, and potential warranty issues. Always ensure your ASHP is commissioned by a qualified, experienced professional.
