Air source heat pumps are becoming a popular choice for homeowners in Norfolk and Norwich who want a low-carbon, cost-effective way to heat their homes. While these systems are designed for reliability and a long lifespan, regular maintenance is crucial to ensuring they continue to run efficiently and economically. In this guide, we’ll examine the necessary maintenance for air source heat pumps, discuss what you can do yourself, and determine when to call in the professionals.
Keeping Your Air Source Heat Pump Running Efficiently
Regular Visual Checks
Homeowners can perform simple visual inspections every few months to check for any potential issues. Ensure the outdoor unit is clear of leaves, dust, and other debris that can block airflow. Clear away any plants, grass, or garden materials within a metre of the unit to prevent obstructions. Also, inspect the coils for signs of damage, corrosion, or ice buildup during colder months.
Cleaning Filters and Coils
Blocked filters and dirty coils reduce airflow and efficiency. Most air source heat pumps have removable filters that should be cleaned or replaced every few months, depending on usage and environmental conditions. Gently cleaning the outdoor coil with water (never harsh chemicals) also helps maintain good heat exchange and consistent performance.
Checking the System Pressure
Like any heating system, an air source heat pump depends on correct pressure to circulate heat effectively. If you notice inconsistent heating, your system may have lost some pressure. This can sometimes be topped up, but it’s best to let a qualified technician handle it to avoid damage or leaks.
Annual Professional Servicing
Check refrigerant levels and pressure
Refrigerant is the fluid that transfers heat between the indoor and outdoor units. If levels drop too low, your system will struggle to absorb and release heat efficiently, resulting in increased running costs and reduced performance. The technician measures the pressure and refills the refrigerant if necessary, ensuring the system operates at peak efficiency.
Test electrical connections and controls
Loose or corroded connections can affect the power supply and cause intermittent faults. The installer will test all electrical components, including sensors, fuses, thermostats, and control boards, to make sure they are functioning correctly. This helps prevent potential breakdowns and ensures safe, reliable operation.
Inspect and clean internal components
Dust, dirt, and debris can build up inside the system over time, particularly around the fan and coils. Cleaning these parts enables better airflow and heat exchange, thereby reducing strain on the unit. The technician also checks for wear or corrosion that might indicate parts need replacing soon.
Confirm system performance and efficiency readings
Your installer will run a series of tests to measure the system’s output and energy efficiency. By comparing current readings to manufacturer specifications, they can confirm whether your heat pump is working as efficiently as possible or if adjustments are needed to improve performance.
Identify any worn or failing parts before they become costly issues
One of the primary benefits of annual servicing is the ability to catch small issues early. Components such as fan motors, expansion valves, or sensors can wear out over time. Identifying and replacing them before they fail helps avoid expensive repairs and system downtime during colder months.
Seasonal Adjustments and Efficiency Tips
As temperatures change, your system’s settings may need to be adjusted. Ensure your thermostat and timer are properly programmed to meet seasonal demands. It’s also worth periodically checking the insulation around your property to help your heat pump perform optimally without overworking.
