Most AC breakdowns in Newton start with a small part: the run capacitor. It helps start the compressor and condenser fan, loses strength slowly over the years, and tends to give out on the hottest afternoon, which is why so many service calls begin with an outdoor unit that hums while the fan sits motionless. Other frequent culprits include contactors with pitted, burned points, fan motors whose bearings have run dry, slow refrigerant leaks that steadily rob capacity, and evaporator coils that turn into blocks of ice once a dirty filter chokes the airflow.

Warning Signs for AC Repair
Spotting the early warning signs lets you act before the problem gets expensive. Here are the most common indicators that it's time to call a professional:
- Puddles near the air handler or water stains on the ceiling beneath it
- Rising electric costs paired with a sticky, uncomfortable house
- The outdoor unit humming or clicking but the fan not spinning
- A hiss or gurgle from the lines, a common sign of leaking refrigerant
- Room-temperature air from the registers even though the AC is running
- Ice on the refrigerant lines or a frozen indoor coil
- The system short-cycling every few minutes without cooling the house
- A burning smell or repeated breaker trips when the AC starts
