Common Heat Pump Problems We Diagnose

Most heat pump issues aren't caused by a faulty unit. They come from poor system design, incorrect setup, or controls that were never configured properly problems that should have been picked up at installation.

If your system isn't performing as it should, it's usually one of these:

  • Electricity bills much higher than expected

  • House not reaching temperature even when the system is running continuously

  • Radiators that feel barely warm or inconsistent between rooms

  • Hot water that runs out or doesn't heat fully

  • A system that was signed off but never felt right

Why Homeowners Come to Us Instead of Going Back to Their Installer

When your heat pump isn't performing, your installer often has a commercial interest in the answer. They may say the system is fine, blame the house, or suggest expensive upgrades. We have no interest in any of that.

We don't install systems. We don't sell equipment. We don't subcontract to installers. We review your system and give you an honest technical assessment so you know exactly where you stand, and what to ask for.
