AC Not Cooling in Alpharetta, GA
An air conditioner running without cooling your home typically points to restricted airflow from a clogged filter or frosted evaporator coil, a failed start capacitor or contactor, an overheated blower motor, or refrigerant loss from a sealed line leak. When system components fail to transfer heat outdoors, indoor temperatures climb quickly. Our own experienced technicians inspect the electrical draw, mechanical components, and refrigerant pressures directly at your Alpharetta residence to isolate the issue and explain your repair options clearly.
Signs Your AC Isn't Cooling
Recognizing early warning signs helps you address cooling failures before components overheat or suffer severe mechanical damage.
Warm Air from Supply Registers
The blower continues circulating air through your vents, but the air feels tepid or humid because the outdoor unit is not absorbing and rejecting heat.
Constant Running Without Reaching Setpoint
Your system runs continuously for hours while indoor temperatures remain stubbornly above your thermostat setting, driving up energy consumption.
Frequent Short Cycling Cycles
The outdoor condenser starts up, runs for only two or three minutes, and abruptly shuts down due to high pressure limits or failing electrical controls.
Ice Formation on Copper Lines
Frost or thick ice develops along the indoor evaporator coil and exterior suction line, choking heat transfer and blocking airflow through the air handler.
Weak Airflow from Second-Floor Vents
Upstairs rooms stay uncomfortably hot while register air movement drops significantly, pointing to blower speed issues, blocked duct runs, or heavy coil restriction.
Humming or Clicking Outdoor Sounds
The outdoor unit produces an electrical hum or repeated relay clicking without the fan spinning or compressor starting, signaling capacitor or contactor failure.
