Common Issues We Repair

Reduced Cooling or Heating Performance

We inspect filters, coils, refrigerant levels and airflow pathways to determine why your system isn’t reaching temperature.

Unusual Smells or Odours

Dust, mould, drainage issues or dirty coils can cause unpleasant smells. We identify the source and restore clean airflow.

Noisy Indoor or Outdoor Units

Rattling, buzzing or grinding noises can indicate loose components, fan obstructions or failing parts.

Water Leaks

We check drain lines, blockages and installation issues to stop water leaks and prevent further damage.

Error Codes & Fault Investigation
