Air Source Heat Pump Service in Rotherham and Barnsley: Keep It Running as Designed

What a service costs and what it covers

An annual heat pump service is £240 including VAT at standard rate and £264 in Band A. A set appointment time rather than a standard 4-hour slot adds £30. Refrigerant isn't included if the system needs topping up — we'd quote that separately, and we'd want to find out why it's low rather than just refilling it.

Why a heat pump needs servicing differently to a boiler

A boiler either works or it doesn't. A heat pump can run perfectly happily for years while quietly costing you more than it should.

That's the difference that catches people out. A heat pump with a slightly low refrigerant charge, a filter that hasn't been cleaned, or a flow temperature set 5°C too high will still heat your house. It just does it less efficiently, and the only place that shows up is your electricity bill.

An annual service is what stops that drift. It's also what keeps most manufacturer warranties valid — check yours, but nearly all of them require documented annual servicing.

Signs it's overdue

• Energy bills creeping up without any change in how you use the heating
• Rooms that used to feel warm now feel lukewarm or uneven
• The system runs almost non-stop, even in mild weather
• The filter light or service reminder has come on
• It's been more than twelve months since the last visit

If your system's under three years old and doing any of this, don't assume it's fine just because it's new. Newer units still need airflow, refrigerant levels and controls checked.

If it's making a new noise, tripping the electrics, or icing up and not clearing, that's a fault rather than a service overdue — our heat pump repair page covers what to do.

What we check

Our engineer arrives with a plan, not a guess. It isn't a quick glance and a signature — a heat pump only runs efficiently when every part of it is doing its job.

• Outdoor unit checked for debris, ice buildup, or airflow blockages around the fan
• Refrigerant pressures tested and pipework checked for signs of leaks
• Electrical connections and controls inspected for wear or loose fittings
• Flow and return temperatures checked against what the system was designed to deliver
• Filters cleaned or replaced where needed
• Controller settings reviewed with you, and anything affecting running costs flagged

That fourth one matters more than the rest put together. Flow temperature set too high is the single most common reason a heat pump costs more to run than it should, and it's invisible unless someone measures it against the property's actual heat loss.

You'll get a plain explanation of what we found, what we did, and what to keep an eye on before we leave.

An Engineer Who Can Answer Your Heat Pump Questions

Plenty of people end up with a heat pump and nobody to ask about it: why it seems to run all day, what the settings do, whether that noise is normal. On a service we check the unit and its cylinder, and we answer your questions while we are there, so you know how to get the best from it.

Older properties need the settings reassessed, not just the unit checked

A lot of the housing around Rotherham and Barnsley dates back to the coal-mining era — terraces built for miners' families, still standing, with solid brick walls and smaller radiators than a modern estate.

A heat pump working against that kind of heat loss has to run harder. And the settings that were right at installation may not be right now, because the building changes: new windows, loft insulation topped up, an extension added.

We see plenty of older terraces with flow temperatures set too high because the original design didn't account for the property's real heat loss. Radiators sized for a gas boiler decades ago don't suit a heat pump's lower flow temperatures either. That's a design issue rather than a fault, but it only shows up if someone looks.

So on an older property we check flow temperatures against the actual heat demand, not a generic default — and if the radiators are the limiting factor, we'll tell you what upgrading them would actually buy you.
