Common AC Problems & When to Call for Repair
Air conditioners rarely fail without warning. Knowing what to look for can help you catch a small problem before it becomes a costly breakdown. Here are the most common AC issues homeowners notice—and why they warrant a call to a professional.
AC Not Cooling Properly: If your system is running but your home feels warm, the problem could be low refrigerant, a dirty evaporator coil, or a failing compressor. These issues won't resolve on their own and require a certified technician to diagnose safely.
Strange Noises: Banging, rattling, or squealing sounds from your AC unit often indicate loose components, a failing blower motor, or debris caught in the fan. Ignoring unusual noises can lead to more extensive—and expensive—damage.
High Energy Bills: A sudden spike in your cooling costs without a change in usage usually means your system is working harder than it should. Dirty coils, clogged filters, or refrigerant issues all reduce efficiency and drive up utility bills.
Short Cycling: If your AC turns on and off in rapid, short bursts rather than completing a full cooling cycle, it may be oversized, low on refrigerant, or experiencing electrical problems. Short cycling puts excessive wear on the compressor—the most expensive part of your system.
Ice Forming on Coils: A frozen evaporator coil is a sign of restricted airflow or low refrigerant. Running a system with ice buildup can damage the compressor. If you see ice on your indoor or outdoor unit, turn the system off and call for service.
