Professional Heat Pump Maintenance in Worcestershire

Expert Heat Pump Repairs

If your system develops a fault, you don’t just need a plumber; you need a heating engineer who understands the refrigeration cycle and complex system design. We provide quick, diagnostic-led heat pump repair services in Worcestershire.

We’ve seen it all, and we have the expertise to fix common (and uncommon) faults:

Inconsistent heat: Radiators not getting up to temp or lukewarm water.
Error codes: Deciphering those cryptic messages on your controller.
Ice build-up: When ice has built up on your outdoor unit.
Strange noises: Rattles, vibrations, or clunks that shouldn’t be there.
Efficiency drops: If your bills have suddenly spiked, something is wrong.

While air source heat pumps are incredibly reliable, they are sophisticated pieces of kit, so they need looking after. Our annual heat pump services across Worcestershire keep your system running at its max.

If your system is playing up or it’s simply been over a year since its last check-up, don’t leave it to chance. Get in touch, and we’ll get you booked in for a proper technical service.

Why Regular Heat Pump Servicing Matters

While air source heat pumps are incredibly reliable, they are sophisticated pieces of engineering that benefit from annual professional attention. That’s why we offer regular heat pump system servicing in Worcestershire.

Protect Your Warranty

Most major manufacturers – including Viessmann, Vaillant, Samsung, and Mitsubishi – require an annual service by a certified engineer to keep your warranty valid.

Maximise Efficiency

Over time, debris on the evaporator coils or incorrect flow rates can force your pump to work harder. We optimise your settings to ensure you maintain the highest possible SCoP (Seasonal Coefficient of Performance).

Prevent Winter Breakdowns

A summer or autumn service allows us to catch minor issues before they turn into a mid-winter emergency.

Heat Pump FAQs

Do you service heat pump brands you didn’t install?

Absolutely. While we are Vaillant and Viessmann specialists, we can service most major brands like Samsung, Mitsubishi, and Daikin. If it’s an air source heat pump, we can usually service or repair it.

How often should I have my heat pump serviced?

Once a year. If you wait too long to get your heat pump serviced, the efficiency could drop, and you risk a much more expensive repair down the line. Plus, it’s usually a requirement for your warranty.

Why is my heat pump making a strange noise?

A gentle hum is normal. But if you hear banging, clanking, or a high-pitched whistling, something’s up. It could be as simple as a loose bolt or some leaves caught in the fan, or it could be a sign that a motor is starting to give up. If the noise is new and it’s loud enough to notice from inside, give us a call.

My energy bills have gone up – is my heat pump broken?

Not necessarily “broken,” but it’s likely not running efficiently. If your filters are clogged or the outdoor unit is dirty, the pump has to work twice as hard to get the same amount of heat into your house. A professional service can often pay for itself just by getting your efficiency back to where it should be.

Is it normal for my heat pump to have ice on it?

A little bit of white frost on the coils in winter is perfectly normal. The system has a “defrost mode” to melt this away automatically. However, if the unit looks like a solid block of ice, that’s a problem. It usually means a sensor has failed or the drainage is blocked. If the ice isn’t melting away on its own, it’s time for a repair.
