In this guide, our engineers share expert insight into what goes wrong with heat pumps, how to spot issues early, and when it’s time to call for professional help.
Understanding How Your Heat Pump Works
Before diving into faults, it’s useful to know how a heat pump operates. A heat pump moves heat rather than generating it – extracting warmth from the air or ground and transferring it into your home. With this method, you enjoy lower carbon emissions and reduced energy bills, especially when installed correctly and maintained regularly. At NCC South East, we specialise in heat pump systems in Chislehurst and across Kent, ensuring homeowners get the most efficient systems for their properties.
Common Heat Pump Problems
1. Reduced Heating or Cooling Performance
One of the earliest signs of trouble is reduced thermal performance. If your heat pump seems to be struggling to heat or cool your home as usual, it could suggest a refrigerant leak, clogged filter, or failing component. A professional should check refrigerant levels and airflow to restore performance quickly. Neglecting this issue can lead to higher energy consumption and system wear.
2. Unusual Noises
Heat pumps are typically quiet, so any rattling, grinding, or buzzing noises should be investigated immediately. These sounds could stem from loose components, failing fan motors, or obstructions in the system. Early diagnosis can prevent minor problems from escalating into costly repairs or replacements down the line.
3. Icing and Frost Build-Up
During the winter months, a thin layer of frost on your outdoor unit is normal. However, excess ice accumulation can indicate a defrost cycle fault or airflow restriction. Monitor your unit regularly, and if you notice persistent icing, it may be time for a professional inspection. For instance, our engineers, who are experienced in air source heat pump repair, can quickly identify the cause and restore your system’s balance.
4. Frequent System Cycling
If your heat pump is turning on and off more often than usual, it might be short cycling. This can result from a thermostat fault, low refrigerant, or a compressor issue. Short cycling not only reduces comfort but also increases wear on system components, leading to premature failure. Regular servicing helps prevent these issues before they cause significant damage.
5. Rising Energy Bills
If your energy costs are climbing without a clear reason, your heat pump could be running inefficiently. A blocked filter, refrigerant leak, or outdated settings can all lead to wasted energy. Routine maintenance and timely repairs help keep running costs in check while extending the life of your system.
6. The Unit Fails to Start
A complete failure to power up could stem from electrical faults, tripped breakers, or internal control board issues. While simple resets sometimes resolve the issue, repeated tripping or unresponsive controls need to be inspected by an experienced engineer to avoid electrical hazards.
7. Poor Airflow
Blocked vents or a failing fan motor can cause insufficient airflow throughout your home. If you notice uneven room temperatures or feel little air from vents, it’s best to check for obstructions and book a professional service if the issue persists.
How to Spot Heat Pump Problems Early
Being proactive is the best way to avoid major repairs. Paying attention to how your system feels, sounds, and performs can make all the difference. Watch for irregular cycles, weak output, or strange noises. Additionally, schedule annual servicing to keep your pump in peak condition. At NCC South East, we’re not only heating engineers but also problem solvers, helping you detect and rectify heat pump faults before they become emergencies.

Preventative Measures for Long-Term Reliability
- Clean or replace air filters regularly.
- Keep outdoor units clear of debris and vegetation.
- Check and adjust thermostat settings seasonally.
- Listen and watch for unusual performance changes.
- Book a professional service at least once a year.
Following these steps not only helps your unit run smoothly but also extends its lifespan. Proactive maintenance can prevent common issues such as frozen coils, blocked filters, and electrical malfunctions.
