Air Source Heat Pump Service & Repair

When it comes to maintaining your heat pump, the best time to run any maintenance checks is during the summer months to ensure your system is running effectively before the colder months roll in.

Keep it Spick and Span – as part of your cleaning kit, a nice soft brush would be ideal for dusting away any dirt and debris from several areas of your ASHP. This includes the coils and fan blades. You can then use a damp cloth to wipe down any areas that your brush can’t clean.

Replace and/or Clean Your Filters – depending on your chosen system, your ASHP installer will advise you how often you need to clear or replace your filters. Generally speaking, cleaning your filters will depend on how dirty they become, which could impact their efficiency while replacing filters could be done once a year.

By taking time to do regular spot checks on your ASHP you can help keep it in tip-top condition.

Drain Tray – keep an eye on the drain tray, which collects condensation from the unit. If it becomes full, it could overflow onto your path and freeze in colder weather, becoming a slip hazard. It could also become mouldy or create algae, so it’s always advisable to stay on top of it and clean it out now and then.

Antifreeze – try and stay on top of refilling the antifreeze as this helps prevent the unit from freezing over winter. It’s one of those minor jobs that could make a big difference in helping to prevent your ASHP from breaking down when you need it most.

Water Pressure – similar to a gas-fuelled boiler, you’ll need to review the water pressure of your ASHP at regular intervals. Depending on the size of your property, this could range from 0.7 bar to 1.2 bar; your installer will have confirmed what’s right for your home at the point of installation, and make sure you check the pressure when the system is cold (not in operation).

As you know, an ASHP works by using air from the outside as a source of heat, but for it to work effectively, you’ll want to ensure you don’t have any obstructions in front of it that could prevent it from working efficiently.

Try to keep any grass that is close by short and clear away any leaves or debris that may get in the way of the unit.

We’re fortunate to live in a world where our heating and hot water can easily be controlled either via our phones, thanks to smart apps or digital controls, and this is no different when it comes to air source heat pumps.

However, now and then, it would be worth checking your thermostat and thermostatic radiator valves (TRVs) are working in harmony. Do they all respond accordingly if you increase or reduce the temperature output?

Any issues, it’s worth calling out an Elite engineer to investigate what could be causing this issue.

Furthermore, it is worth checking the controls for the hot water to ensure the system works as it has been programmed to do.

You can do everything you can to maintain your ASHP, but it’s also worth considering an annual service for a more detailed and expert health check of your device, ideally during summer or autumn.

An annual service, either organised through your ASHP installer or by yourself, carried out by a qualified technician who can inspect and service your heat pump to address any potential issues, should give you peace of mind that your system is in good working order before you reliance on it kicks in during winter.
