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.

Didn't read the report properly as two issues had been logged, only looked at one and then blamed my daughter who let him in the home for not telling him properly where to look. Didn't bother to get him to come back, as turned angry on phone and moaned about parking and the second fault was wear and tear and not Thames Water problem any way. Took a tap out of my skip on front without asking as said he could make money from it. Wouldn't have minded him taking it but should have asked first.
