Repair or replace a heat pump?
Repair it if it's under about 15 years old and the fault is a part: a pump, a sensor, a valve, a board. Think about replacing it when the compressor fails on an older unit. A replacement that hasn't had an SEAI grant before can get up to €6,500.

- €140 to €400a fault call-out with a minor repair

- 15 yearswhere a compressor failure tips it
Four questions to ask
- How old is it? Most faults on a heat pump under 15 years old are worth repairing.
- What's failed? A pump, a sensor, a valve, an expansion vessel or a control board is a repair. A failed compressor on an old unit is where replacement starts to make sense.
- Is it under warranty? Check before anyone opens it: registration and a yearly service often keep it valid.
- Would a grant help? If the old unit never had an SEAI grant, a replacement can get up to €6,500. Approval comes before the work.

Questions we get asked
How long does a heat pump last?
Usually 15 years or more with a yearly service. The compressor is the part that decides it.
Is a compressor worth replacing?
On a newer unit under warranty, yes. On an older unit, compare the price with a new heat pump after the grant.
Will a new heat pump be more efficient?
Usually. Newer units and controls run more efficiently, especially with the weather compensation set up properly.
