I got into this situation last week when my AC started acting up gradually, first with weak airflow and some rattling noises, and then one afternoon it just completely stopped cooling while I was trying to work from home. The apartment quickly became unbearably hot, and it was impossible to concentrate. I tried resetting the thermostat, checking vents, and even swapping filters, but nothing worked. I’ve had technicians in the past who rushed through the process and barely explained anything, so this time I stayed attentive, asked questions, and watched what they were doing. It was honestly a relief when someone walked me through every step and explained what could fail next. That experience made me realize how important it is to notice small warning signs early because waiting until the system fully dies usually makes the situation worse, especially when it happens at the worst possible moment.
