Car AC Not Working in Greenville, NC?

Why Your Car's AC Stopped Blowing Cold

Your AC is a sealed, pressurized loop circulating refrigerant (R-134a or R-1234yf in newer vehicles) through a compressor, condenser, expansion valve, and evaporator. When any component fails or refrigerant leaks out, you lose cold air.

AC Blows Warm or Hot Air

• Low refrigerant — Most frequent cause. Refrigerant doesn't wear out — if it's low, there's a leak. Recharging without fixing the leak is a temporary fix
• Failed compressor — If the clutch isn't engaging or the compressor is seized, no refrigerant circulates
• Electrical issue — Blown fuse, failed relay, or bad pressure switch preventing compressor engagement

AC Starts Cold Then Gets Warm

• Low refrigerant — Enough to start cooling, not enough to sustain under heat load
• Intermittent compressor clutch — Engages and disengages irregularly
• Clogged expansion valve — Restricts refrigerant flow intermittently

Weak Airflow from Vents

• Clogged cabin air filter — Most common and cheapest fix. Located behind the glove box on most vehicles
• Blower motor failure — Motor runs slowly or only works on certain speeds
• Blend door actuator — Stuck door bypasses the cooling element

Why "Just Recharging" Often Fails

If the system is low on refrigerant, there's a leak. Adding more without finding the leak costs you money each time it leaks back out. Proper diagnosis includes pressure testing, UV dye leak detection, compressor inspection, and electrical testing.
