Common Heat Pump Problems We Repair

Even with regular maintenance, heat pumps can develop faults over time. At Metro Plumb, we know how important it is to keep your heating system running efficiently, especially in colder months. That’s why our expert engineers are fully trained to quickly diagnose and repair a wide range of heat pump issues, including:

Faulty condensers

A faulty condenser can impact your system’s ability to transfer heat. We’ll inspect and replace damaged components to restore performance.

Broken fans or compressors

If your fan isn’t spinning or your compressor is noisy, we’ll find the root cause and carry out accurate repairs or replacements.

Ductwork or pipework leaks

Leaks can reduce efficiency and raise energy bills. We detect and seal them to keep your system airtight.

Electrical or control board issues

From faulty wiring to broken thermostats, we troubleshoot and fix electrical faults affecting your system’s performance.

Reduced heat output or airflow

If your system isn’t as warm as it should be, we’ll check airflow, refrigerant levels, and pressure to fix the issue.

Our goal is to minimise downtime and restore your heating quickly, so you can get back to comfort without delay.

Has a great experience with the plumber taking due care & attention. The young man helped diagnose the issue that was ongoing with Thames Water for over 3 months, then to fulfil the final part of the job reinstating water back into our property. Metro Plumbing was key & influential in getting a resolution to our complex issue. Thank you.

We booked a septic tank empty. The engineer arrived the next day & rang to tell us when he was arriving. He arrived on time and was very polite & friendly and did a clean & efficient job. Would recommend.

Brian was sent along by Welsh Water to confirm the septic tank I told them about actually existed. Bit of a waste of time really.
