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.

The guy who came to do the drain was the first in years who managed to clear it, it has been blocked for at least 8 years. Other workmen had said that they couldn't get around the bend, or couldn't locate the issue. This guy worked very hard to find the problem, and after a few hours he managed to clear it. I'm over the moon that I can now clean my garden properly. The guy was very friendly and helpful. I give him 5* all around. Highly recommend! 😁

Yes, he did a wonderful job of clearing a stubborn airlock in my gravity fed system leaving me with free flowing cold water to all the upstairs taps and toilets - and no mess. He was friendly and polite. Great service.

I had a really fantastic experience with Metro Plumb, a rocky start as first appointment missed but they were under pressure i am sure. The customer service and plumbers were outstanding. Thankyou Amy Young for great help and communication and Mohammad and Ravi who did such an excellant job in understanding the issues and installing a lovely new tap. A really great team and meant a lot to me.

We are a local Charity serving the community... Eg toddlers this morning OAPs tomorrow... We need our drains to work... They saw us struggling and came over to help! Had everything moving in minutes. We can't thank you enough! Highly recommend!

We had out sewage tank emptied today and the engineer, Paul, did a fabulous job. He was efficient, polite and friendly and most importantly took pains to ensure the work was undertaken cleanly. We don't have the easiest property to service, so thank you Paul!
