Frequently Asked Questions
Q: How often should I service my heat pump?
At P&R Mechanical, we recommend servicing your air source heat pump annually to maintain optimal performance and efficiency. Heat pumps work continuously throughout the year for both heating and hot water, making regular maintenance essential. Most manufacturers specify annual servicing to maintain warranty coverage, typically scheduling in spring or autumn between peak heating and cooling seasons. For systems over 5 years old or in coastal areas where corrosion is a concern, we sometimes recommend more frequent checks.
Q: What does a heat pump service include?
Our comprehensive heat pump service begins with a visual inspection of both indoor and outdoor units, checking for physical damage or corrosion. We then clean or replace air filters, clean the evaporator and condenser coils, check refrigerant levels, inspect electrical connections and components, test the defrost cycle, verify control system operation, and assess overall system performance and efficiency. We also check the condensate drain system for blockages and clean the outdoor unit fan and coils to remove debris that could restrict airflow.
Q: How much does a heat pump service cost?
At P&R Mechanical, our standard heat pump service costs £80, which includes both the callout and diagnostic assessment. This transparent pricing applies during normal working hours. For more complex work requiring additional time, our clear hourly rates will be explained before any extra work begins. Our price is significantly lower than the Buckinghamshire average for heat pump servicing (typically £140), reflecting our commitment to fair pricing while delivering professional expertise.
Q: Do you install heat pumps?
No, P&R Mechanical does not currently install heat pump systems. We specialize in servicing and maintaining existing heat pump installations throughout Buckinghamshire. Our engineers have received specific training in heat pump maintenance and can provide expert servicing for all major brands including Mitsubishi, Daikin, Samsung, Vaillant, and others. If your existing heat pump requires maintenance, repair, or annual servicing, we have the expertise to help keep your system running efficiently.
Q: Can heat pumps be serviced in winter?
Yes, heat pumps can be serviced during winter, but at P&R Mechanical, we recommend scheduling routine maintenance during milder seasons when possible. If your heat pump requires immediate attention during winter, our engineers are fully equipped to perform service work in cold conditions. During winter servicing, we minimize system downtime to prevent your property from cooling excessively. For routine maintenance, scheduling service in spring or autumn typically allows for more thorough cleaning of the outdoor unit without disrupting your heating during colder periods.
Q: What are signs that my heat pump needs servicing?
Signs that your heat pump needs immediate servicing include reduced heating or hot water performance, unusual noises (particularly grinding or rattling), ice buildup on the outdoor unit outside of defrost cycles, higher than normal energy bills, or frequent system cycling. At P&R Mechanical, we can diagnose these issues during our service visit. However, we recommend not waiting for obvious problems to develop—regular annual maintenance helps identify potential issues before they affect system performance or lead to costly repairs.
