Is Your Air Conditioner Showing One of These Signs?

Air conditioning issues can arise gradually or suddenly, particularly in hot weather. It's crucial not to wait for the problem to worsen.


J&J Climatisation can assist if you notice any of these signs:

  • Your AC isn't cooling properly.
  • The air is warm or weak.
  • Unusual noises are coming from the unit.
  • The system frequently starts and stops.
  • Water is leaking near the unit.
  • There's a bad odour from the unit or ducts.
  • The AC runs for long periods without reaching the desired temperature.
  • Your electricity bill is inexplicably rising.
  • The system won't start.


These symptoms may signal electrical issues, faulty parts, or refrigerant leaks. A professional inspection offers a reliable diagnosis and prevents ineffective temporary repairs.

Our Air Conditioning Repair Process

A successful air conditioning repair begins with a thorough understanding of the issue at hand.


At J&J Climatisation, we start by engaging in a conversation about the concerns you've observed, whether it's weak cooling, strange noises, water leaks, frequent shutdowns, unpleasant odours, decreased performance, or a total breakdown.


Our team then assesses the system’s function to pinpoint the possible causes of the problem, examining visible components, drainage, ventilation, filters, signs of wear, or the symptoms you've reported. After identifying the issue, we present the available solutions, which may include a repair, part replacement, maintenance work, or broader advice if the system is significantly worn.


Once the repair is finalized, we ensure the system is operating correctly, guaranteeing that the air conditioning effectively meets the building’s needs, restores indoor comfort, and minimizes the likelihood of future breakdowns.
