Before you book: heat pump repairs in Worthing

Whoever installed your heat pump, aftercare can be arranged in Worthing. Tell us the make and model and roughly how old it is, and we will set out what the visit involves before you book.

Repairs in Worthing that need a part ordered are explained and priced before the engineer leaves. For repeated faults in Worthing, the engineer looks at the system design as well as the failed part.

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
  • Outdoor units that have become noisy, iced up or keep switching on and off
  • Rooms or hot water not getting warm enough

What's included

  • A clear explanation of the fault and a price for the repair before work goes ahead
  • Supply and fitting of replacement parts
  • Reading of error history and operating data
  • System refill, venting and recommissioning after the repair
  • Fault-finding visit at a rate agreed before attending

Heat pump owners in Worthing can arrange a fault-finding visit at a rate agreed before an engineer attends.

Heat pump repairs in Worthing: questions

Will the engineer need access indoors as well as outside?

Usually yes. The outdoor unit, the hot water cylinder, the controls and the pipework and valves indoors are all part of the visit, so allow access to each.

What should I check before booking a visit in Worthing?

Note any error code on the controller, check the system pressure gauge if you have one, and make sure the outdoor unit is clear of leaves or snow. Photos of the unit and controller help.

How often should a heat pump in Worthing be serviced?

Once a year is the usual recommendation, and many manufacturers make annual servicing a condition of the warranty. Check your warranty terms for the exact requirement.

How much does a heat pump repair cost?

Heat pump repairs have a typical range of £90–£1,100, including VAT, depending on the part and labour involved. Sensor replacements sit at the lower end, while control boards and refrigerant repairs on split systems sit higher. Every repair starts with a fault-finding visit, with a guide price of £90–£180 for the first hour, and the repair is priced before work goes ahead.

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.
