An ageing air conditioner may show its limits gradually.
- Rooms can feel unevenly cooled, the system may run for long stretches, or the thermostat may reach its setting only briefly before the house warms again.
- Weak airflow, unusual grinding or buzzing, repeated electrical interruptions, water near the indoor coil, ice on refrigerant lines, and a persistent musty odour are useful clues that the equipment needs attention.
- A sudden loss of cooling, burning smell, or exposed wiring deserves prompt professional attention.
- Turn the equipment off if continued operation appears unsafe, and keep children away from any standing water or damaged components.
