Your vehicle's AC system helps keep its interior cool during a drive. How it works is easy. A compressor converts liquid refrigerant into a hot gas under pressure; a condenser turns the gas back into a fluid by chilling it, and an expansion valve draws the fluid in, making it into a low-pressure gas in the process. An evaporator gets help from a cooling fan to rapidly lower the gas's temperature, and chilled air results. That air travels through your vehicle's ducts, out its vents, and into its cabin.
Unfortunately, car AC systems' seals can weaken from use and age, their hoses can degrade and break, and even their compressors can go bad. When these things happen, other problems follow. Luckily, there are signs to watch out for. They include:
- Improper cooling
- Higher-than-normal interior temperatures
- Strange noises when the AC runs
- A stuck compressor clutch
- Frost buildup
- A flashing AC button
- A lit HVAC warning indicator
- Discharge pressure issues
An air conditioner that won't cool often indicates low or leaking refrigerant. A hot cabin, the atypical sounds, and the stuck clutch usually mean a bad AC compressor. Frost, the flashing button, the lit warning light, and pressure problems more than likely mean a bad AC condenser.
