What to know about heat pump repairs in Blackburn
Whoever installed your heat pump, aftercare can be arranged in Blackburn. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.
Outdoor units in exposed spots around Blackburn can ice more heavily, so siting is checked as part of any icing fault. We repair heat pumps in Blackburn whoever installed them, including older monobloc and split systems.
When a heat pump shows an error, loses pressure or stops heating, an engineer diagnoses the cause and explains the repair and its cost before fixing it.
- Systems losing pressure or needing frequent topping up
- Heat pumps installed by another company that need a second opinion
- Outdoor units that have become noisy, iced up or keep switching on and off

Heat pump repairs in Blackburn: questions
Can you work on a heat pump in Blackburn that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Blackburn, whoever fitted them. Tell us the make and model when you get in touch.

Do you also cover Darwen?
Yes. We arrange heat pump servicing and repairs in Darwen, which is about 4 miles south of Blackburn, and across Lancashire.
Can you repair a heat pump installed by another company?
Yes. We carry out fault-finding and repairs on heat pumps installed by other companies, including monobloc and split systems. Tell us the make, model and approximate age when you get in touch, plus any error code shown. If the system is still under the manufacturer's warranty, it may be quicker to contact the original installer or manufacturer first.
Why is my heat pump showing an error code?
An error code is the heat pump's way of reporting a problem it has detected, such as low water flow, a sensor reading out of range or a communication fault between units. Note the code and check the manual, as some codes clear after a simple reset or pressure top-up. If it returns, an engineer can trace the underlying cause.
