The real reasons aircon performance drops
Common causes include low refrigerant, compressor issues, clogged filters, and faulty sensors or control modules.
Without diagnostics, topping up gas alone is usually a short-term fix.
How to avoid repeat visits
Insist on leak checks and compressor performance testing before approving repairs. This ensures the workshop treats the cause, not just the symptom.
A complete aircon service should include system pressure checks and vent temperature verification after repair.
When to service proactively
If cooling feels weaker at idle or during hot afternoons, schedule inspection early. Catching issues early usually prevents larger compressor-related costs.
Preventive checks are cheaper than emergency breakdown repairs.
