Heat Pump Repairs in Kent

Rapid Diagnostic and Repair Services

A failing heating system is incredibly stressful, particularly during the harsh winter months. If your air source or ground source heat pump has stopped working, is displaying a complex error code, or is failing to provide adequate heating or hot water, you need immediate, expert assistance. CPSL Kent provides rapid, highly analytical heat pump repair services across Kent. We do not guess; we utilise advanced diagnostic tools to pinpoint the exact root cause of the failure.

Unlike traditional gas boilers, heat pumps involve complex refrigeration cycles, high-voltage electrical components, and intricate hydraulic systems. Diagnosing a fault requires a deep understanding of thermodynamics and fluid dynamics. Our engineers are fully F-Gas certified and hold advanced qualifications in heat pump fault finding. Whether the issue lies with a faulty thermistor, a seized circulation pump, a blocked expansion valve, or a catastrophic compressor failure, we have the expertise to resolve it safely.

Common Heat Pump Faults We Resolve

Many heat pump issues manifest as low system pressure or flow rate errors. This often indicates a leak within the primary heating circuit or a failure in the expansion vessel. If your system is constantly losing pressure, our engineers will trace the pipework, locate the leak, repair the joint, and safely re-pressurise the system. Another frequent issue is a heat pump that runs continuously but fails to warm the house. This can be caused by severely depleted refrigerant levels, a malfunctioning defrost cycle leading to a frozen evaporator, or incorrect weather compensation settings.

We also regularly attend to electrical faults. Heat pumps rely on complex printed circuit boards (PCBs) and inverters. Power surges or component degradation can cause these boards to fail, resulting in total system shutdown. Our engineers carry multimeters and specific diagnostic software to test these electrical components, identifying exactly which board or relay has failed so we can source the correct genuine replacement part from the manufacturer.

Transparent, Honest Engineering

At CPSL Kent, transparency is at the core of our repair service. When we diagnose a fault, we explain the issue to you in clear, understandable terms. We will never recommend a costly replacement part if a simple repair or parameter adjustment will solve the problem. Before undertaking any major repair work, we provide a clear, upfront quotation detailing the cost of labour and components.

In cases where an older heat pump has suffered a catastrophic failure (such as a seized compressor) and is out of warranty, we will provide an honest assessment of whether the repair is economically viable compared to upgrading to a modern, significantly more efficient system. Our goal is to get your heating and hot water restored as quickly, safely, and cost-effectively as possible.
