Find a verified Heat Pump Repair in Ireland

If the system is producing heat normally but you want a check-up, that's annual service. If you're seeing faults — error codes on the controller, no heat, water not getting hot enough, the outdoor unit not running, or unusual noises — that's repair. Service typically runs €100–€180. Repair starts with diagnostic and varies with the fault. Don't ignore error codes that auto-clear: they often reappear.

Air-source heat pumps work harder in temperatures below 0°C — that's normal. But struggling could indicate insufficient airflow (blocked air filter, debris around the outdoor unit), a failing defrost cycle (ice buildup on coils), low refrigerant, or a system that was undersized for the property. A diagnostic can usually identify which it is in 60–90 minutes.

Most major brands hold parts for 10+ years post-discontinuation, but specialty refrigerants used pre-2020 (R410A, R407C) are getting scarcer and pricier. If your unit is over 12 years old and needs significant repair, ask the engineer about the cost of replacement vs repair — it's often the right time to upgrade, especially with current SEAI grants for new heat pump installs.

Yes. An annual service catches small issues early, keeps efficiency high, and is required to maintain most manufacturer warranties. Service includes filter cleaning, refrigerant pressure check, electrical safety check, control settings review, and a heat output test. It typically takes 60–90 minutes and costs €100–€180. Skipping service often voids warranty cover on parts and labour.

Plumbers can handle the wet side — cylinder, buffer, radiators, manifolds, controls. But anything involving the refrigerant circuit (compressor, expansion valve, evaporator, condenser, pipework) legally requires F-Gas certification. Many Irish heat pump installers hold both. If a plumber says they can repair your heat pump, ask specifically if they're F-Gas certified before booking refrigerant work.
