Introduction
Knowing the signs of a failing air conditioner can help you address issues early and prevent breakdowns during peak summer months. Here are common signs that your AC needs repair and when to call an HVAC technician.

Weak or Inconsistent Airflow
If you notice weak or inconsistent airflow from the vents, there could be a blockage in the ductwork or a problem with the fan. Weak airflow makes it harder to cool rooms evenly, so it’s best to have a technician assess the system and identify any obstructions or component failures.

Unusual Noises During Operation
Loud noises, such as grinding, squealing, or rattling, indicate mechanical issues within the unit. Grinding sounds often signal motor issues, while squealing could mean a loose belt or fan. Ignoring these noises can lead to more severe damage, so contacting a professional for inspection and repair is essential.

Foul Odors or Musty Smells
Strange odors coming from the vents may be a sign of mold, mildew, or burned-out wiring. Mold growth within the unit or ductwork not only affects air quality but can also worsen respiratory issues. Have an HVAC technician check for moisture issues and clean or replace any affected components to ensure clean air.

Frequent Cycling or High HumidityIf your AC is frequently turning on and off (short cycling) or struggling to control indoor humidity, it may be an issue with the thermostat, refrigerant levels, or the compressor. Frequent cycling reduces efficiency and places strain on the system, so a professional inspection is recommended to identify the cause.
