My AC is not cooling or not blowing cold air. What should I check first in Norwalk?
Confirm the thermostat is set to COOL and below room temperature, replace a dirty air filter, check the indoor and outdoor breakers, and make sure the outdoor unit fan is spinning and the coil is not clogged with dust. If the coil is iced over, switch the system OFF and the fan ON to thaw, then call us - ice usually means low refrigerant or an airflow problem.
