Introduction An unexpected AC failure can be frustrating, especially during peak summer months. Whether your unit has stopped cooling, is making unusual noises, or won’t turn on at all, acting quickly can prevent further damage and discomfort. This guide will walk you through essential steps to diagnose and fix AC issues before calling a professional.
1. Common AC Problems and Quick Fixes
1.1 AC Won’t Turn On
- Check the Thermostat: Ensure it’s set to cooling mode and the temperature is lower than the room temperature.
- Inspect the Circuit Breaker: A tripped breaker can shut down the unit. Reset it if necessary.
- Examine the Power Supply: Ensure the AC unit is plugged in and receiving power.
1.2 Weak or No Airflow
- Replace the Air Filter: A clogged filter restricts airflow. Change it every 1-3 months.
