Common AC System Problems

• Thermostat Issues: Incorrect settings, dead batteries, or a malfunctioning thermostat can prevent the AC from turning on.
• Tripped Breaker: A tripped breaker or blown fuse can cut power to the AC unit.
• Dirty Air Filter: Clogged filters restrict airflow, causing the unit to freeze up or function poorly.
• Refrigerant Leak: Low refrigerant levels due to leaks can lead to inadequate cooling and can prevent the AC from turning on. We offer AC Recharge Services if your refrigerant levels are low.
• Dirty Coils: The outdoor unit’s coils can become dirty, reducing the system's ability to expel heat and causing it to shut down.
• Faulty Capacitor or Contactor: These electrical components help start the compressor and fan. If they're malfunctioning, the AC won’t operate.
• Clogged Drain Line: A full or clogged condensate drain line can trigger a safety switch that turns off the AC.
• Frozen AC System: Insufficient airflow or low refrigerant can cause the air conditioner to freeze up, which slows the system's ability to cool.
• Compressor Issues: If the compressor is failing or dead, the entire system won’t work.
• Faulty Control Board or Motor: Electrical issues, such as a faulty control board or a burned-out blower motor, can prevent the AC from starting.
• Thermostatic Expansion Valve (TXV) Issues: A malfunctioning TXV can restrict refrigerant flow, affecting the AC's performance.
• Improper Installation: Incorrect sizing or installation can lead to inefficiencies and operational problems.
• Old HVAC System: Over time, wear and tear on AC components can lead to decreased efficiency and eventual failure.
• Compressor Motor Failures: if the motor is failing the system may develop unusual noises or stop working. Just like the motor in a vehicle, neglecting maintenance can shorten the motors lifespan and cause HVAC system failures.
