Both systems need model-specific checks, accurate fault information and a competent technician. The main practical difference for an owner is the exact model, controller, documentation and parts route.
Model beats brand alone
Each manufacturer sells multiple ranges and generations. Photograph the rating plate and controller rather than reporting only the brand.
For a Cork home, note the system make, model and the conditions when the issue appears. Clear information reduces guesswork and helps the person returning your call decide whether the visit should be routine maintenance or fault diagnosis.
Controller information
Error histories and user menus differ. Preserve the exact code and avoid applying instructions intended for another model.

Parts and technical support
Availability varies by component and model age. Ask whether a return visit may be needed once the fault is identified.

Warranty and approved status
Check the written terms. This website does not claim authorisation from either manufacturer.

What to ask before the visit
Ask what the quoted visit includes, whether VAT and travel are included, what record you receive, and how additional work will be approved. Confirm experience with your exact system. Do not assume brand authorisation, qualifications, warranty protection or response time unless the appointed business confirms it in writing.
Prepare useful information
Write down the make and full model number from the rating plate, the exact controller message, which functions still work, and when the problem began. Note whether it follows a power cut, a settings change, very cold weather or recent work elsewhere in the heating system. If the fault is intermittent, a short video or photograph taken from a safe position may help. Keep the outdoor and indoor equipment accessible, but do not remove covers.
For a routine service, gather the installation handover and previous reports. For a repair, describe the active symptom when booking so the correct amount of diagnostic time can be allowed. Ask the operator to explain findings and seek approval before fitting chargeable parts.
Useful next step
If you still need help, read the heat pump repair guide or request a callback. For another homeowner question, browse the heat pump guides.
