At Heatswap, our heat pump servicing in Gravesend is meticulous and transparent, giving you total peace of mind that your home’s heating is in top condition.

This not only keeps your monthly energy bills down but significantly extends the operational life of your equipment.

Expert Heat Pump Repairs

If your system develops a fault, you need an engineer who truly understands the refrigeration cycle and complex system design. Based in Gravesend, we provide rapid, reliable heat pump repairs across London, Kent, Essex and the rest of the South East. We focus on accurate diagnostics and honest, professional advice to get your heating back online as quickly as possible.

We have extensive experience resolving common faults such as:

Inconsistent heat output or cold radiators
Sudden system shutdowns and error codes
Excessive ice build-up on the outdoor unit
Unusually noisy operation or vibrations
Low refrigerant levels and F-Gas leaks
Sensor failures and electrical communication issues

Whatever the fault, we’ll identify the root cause, explain the solution clearly, and ensure your system is restored to its highest performance levels.

Why Regular Heat Pump Servicing Matters

While air source heat pumps are incredibly reliable, they are sophisticated pieces of engineering that benefit from annual professional attention. That’s why we offer regular heat pump system servicing in Gravesend and beyond.

Protect Your Warranty

Most major manufacturers – including Vaillant, Samsung, and Mitsubishi – require an annual service by a certified engineer to keep your warranty valid.

Maximise Efficiency

Over time, debris on the evaporator coils or incorrect flow rates can force your pump to work harder. We optimise your settings to ensure you maintain the highest possible SCoP (Seasonal Coefficient of Performance).

Prevent Winter Breakdowns

A summer or autumn service allows us to catch minor issues before they turn into a mid-winter emergency.

Commercial Heat Pump Repairs & Servicing

For businesses, property developers, and landlords, a functioning heating system is critical for both operational continuity and cost control. We provide specialist commercial heat pump repair and servicing in Gravesend and across the South East, ensuring large-scale renewable systems deliver maximum ROI with minimal downtime.

Our F-Gas certified engineers have the technical expertise to handle high-capacity systems and sophisticated energy management controls, keeping your building’s climate stable year-round.

Our Heat Pump Servicing Process

At Heatswap, we don’t believe in “quick look” servicing. Because we are Heat Geek and MCS-accredited specialists, our maintenance process is a deep-level technical audit designed to squeeze every bit of efficiency out of your system.

Performance & Airflow Optimisation

We start with the outdoor unit, performing a deep clean of the evaporator fins to ensure there is zero restriction to airflow. We also check the fan balance and motor to ensure the unit remains as quiet as the day it was installed.

Hydraulic & Fluid Health

We check your system’s water pressure and, more importantly, the concentration levels of your glycol (antifreeze) and corrosion inhibitors. We also remove and clean your magnetic system filter.

F-Gas & Electrical Safety

As F-Gas certified engineers, we carry out a full leak detection check on the refrigerant circuit. We also inspect the electrical terminals for any signs of wear or heat damage and verify that the compressor and sensors are operating within the manufacturer’s specific tolerances.

Handover & Warranty Support

Once finished, we provide a full service report. This acts as your proof of maintenance for manufacturer warranties and government compliance.

Frequently Asked Questions

How often should my heat pump be serviced?

To maintain peak performance and reliability, your heat pump should be professionally serviced once a year. While heat pumps are incredibly durable, an annual check-up ensures that small issues are caught before they lead to a breakdown.

Is an annual heat pump service required for my warranty?

Yes. Almost all major manufacturers require proof of an annual service by a qualified engineer to keep your 7-to-10-year warranty valid. Skipping a service could result in your warranty being voided, leaving you liable for the full cost of any future repairs.

Do you repair all types of heat pumps?

Yes, we repair and service almost all major makes and models of air source heat pumps. As F-Gas certified and MCS-accredited engineers, we have the specialist diagnostic tools to support leading brands like Vaillant, Samsung, and Mitsubishi, as well as Daikin, LG, and Panasonic.

Our Heat Geek training ensures we understand the core mechanics of nearly any system, whether it’s a modern domestic unit or a complex commercial installation.

How do I know if my heat pump needs repairing or just a service?

If the system is still running but underperforming, a service is often enough to restore its efficiency and optimize your settings. However, if your heat pump is shutting down, making unusual noises, freezing over, or failing to provide heat and hot water altogether, it likely needs a repair.
If you’re unsure, we can provide a quick diagnostic visit to identify the root cause and explain the most cost-effective approach to getting your system back on track.
