How Often Should You Service Your Air Source Heat Pump?

February 03 2025by Maximum Climate Control

Air Source Heat Pumps (ASHPs) are an energy-efficient way to heat your home. They pull warmth from the outside air and bring it inside, helping you stay warm even in colder months. But like all things in life, they need a bit of care and attention to keep working well. So, how often should you service your air source heat pump or your air heat recovery system? Let’s take a closer look.

What is an Air Source Heat Pump?

Before we dive into maintenance, it’s important to understand what an air source heat pump does. Essentially, it works by transferring heat from the outside air into your home, even when it’s chilly outside. This is great for homes that don’t have access to a gas supply or want to save on energy costs. The system works much like an air conditioning unit in reverse, collecting heat from the air outside and transferring it into your home through an internal heat exchanger.

Why Should You Service Your Air Source Heat Pump?

Air source heat pump maintenance is essential to keep the system running at its best. Just like a car needs regular servicing to stay in good shape, your heat pump also benefits from regular checks and tune-ups. Here are some reasons why:

1. Efficiency – A well-maintained heat pump runs more efficiently, saving you money on your energy bills. If dirt, dust, or debris builds up, it can make the system work harder, meaning it uses more energy to do the same job.
2. Longevity – Proper maintenance can extend the life of your heat pump. With regular servicing, you can help ensure your system lasts as long as possible, potentially even up to 20 years!
3. Air Quality – A heat recovery system or air heat reclamation system can improve the air quality in your home by removing moisture and pollutants. Regular servicing keeps this system clean, ensuring you enjoy healthy air all year round.
4. Prevent Breakdowns – Servicing your heat pump regularly can catch small problems before they turn into big (and costly) issues. This means fewer unexpected repairs and less downtime during the winter months.

How Often Should You Service Your Heat Pump?

When it comes to how often you should service your air source heat pump, the general recommendation is at least once a year. However, several factors can influence this frequency. Firstly, the usage of the heat pump plays a big role. If you use your heat pump every day during the winter, it will likely need servicing more frequently. Homes that rely on their air source heat pumps (ASHPs) for both heating and hot water should have regular checks to ensure the system is performing at its best.

The age of the system is another important consideration. Older systems generally require more attention than newer ones. If your air source heat pump is over 5-10 years old, it’s a good idea to service it more regularly to prevent potential issues and maintain optimal performance. Finally, the location and environment of your home can also impact the maintenance needs of your system. If you live in an area with a lot of dust, pollen, or pollution, your heat pump might need more frequent servicing to keep everything running smoothly. Outdoor units can accumulate dirt and debris more quickly, particularly in rural or coastal areas where salt and sand can affect the system.

What Does an Air Source Heat Pump Service Include?

A proper air source heat pump service involves a comprehensive check of the entire system. During a routine service, an engineer will typically inspect several key components. The air filters inside your air heat recovery system should be cleaned or replaced to maintain proper airflow. Clogged filters can reduce the system’s efficiency and cause it to work harder than necessary. The external unit will be checked for any blockages or damage. This includes ensuring there is no debris, leaves, or ice build-up that could affect the heat pump’s performance.

Refrigerant levels are another critical aspect of your heat pump’s operation. The refrigerant is essential for transferring heat, and if levels are low, it can affect the system’s efficiency. Your engineer will ensure the refrigerant levels are topped up if needed. The technician will also examine the airflow and performance of the system. They will check that the air is flowing properly and that the heat pump is providing the right temperature. Any performance changes may indicate an issue that needs attention.

As heat pumps rely on electrical components, the technician will inspect the electrical connections to make sure everything is wired safely and functioning correctly. Lastly, a thorough system check will be carried out to ensure all components are working optimally. This includes checking the heat reclamation system to ensure it’s effectively recycling heat and maintaining the overall efficiency of the pump.

How to Tell if Your Heat Pump Needs Servicing

Even though regular servicing is key, you might start to notice signs that your heat pump needs attention. Here are some things to keep an eye out for:

1. Increased Energy Bills – If your energy bills start creeping up, it might be because your system isn’t running efficiently. This could mean the filters need cleaning or there’s an issue with the system.
2. Noisy Operation – If your heat pump starts making unusual noises, such as rattling, buzzing, or whistling, it could be a sign that something’s not quite right.
3. Temperature Fluctuations – If your system isn’t maintaining a consistent temperature, it may be time for a check-up. This could point to problems with the compressor or refrigerant levels.
4. Poor Air Quality – If the air quality in your home feels stuffy or musty, your heat recovery system might not be working as it should.

Keep your Home Warm and Energy-Efficient, all year Round!

Regular air source heat pump maintenance is essential for keeping your system running smoothly, efficiently, and effectively. By servicing your heat pump once a year, you’ll improve its performance, reduce your energy bills, and extend its lifespan. Keep an eye out for any unusual signs and get it checked by a professional if you’re unsure. Remember, a little bit of care goes a long way!
