When the summer heat rolls into Denver, PA, the last thing you want is to be stuck in a hot car with a failing air conditioning system. At Green Lawn Garage, we understand just how important your A/C is—not just for comfort, but for safety, especially if you have young children, older passengers, or pets in the vehicle.
The best way to avoid sweating it out is by fixing common auto A/C problems before summer temperatures peak. In this blog, we’ll cover the most common A/C issues, what causes them, and how we can help you stay cool all season long.
Why Is Your Car’s A/C Not Working?
Your vehicle’s A/C system is more complex than most people realize. It includes refrigerant, a compressor, a condenser, expansion valves, and several other components. When one part fails, the entire system can stop working. Here are the most common problems we see at Green Lawn Garage:
1. Weak or Warm Airflow
If your A/C is blowing air that’s not as cold as it used to be—or worse, it’s blowing warm air—this is often a sign of:
- Low refrigerant levels
- A clogged cabin air filter
- A failing compressor
- Leaks in the system
Refrigerant doesn’t just disappear. If it’s low, there’s usually a leak somewhere in the line. Our team uses special leak detection tools to find and fix it before recharging your system.
2. Strange Noises When A/C Is On
Grinding, clicking, or squealing sounds when the A/C is running often mean trouble with the compressor or fan motor. These parts can wear out over time or become damaged by debris.
It’s best to have this looked at early. Catching the issue now can save you from a full system replacement later.
3. Foul Smells from Vents
If you notice a musty, moldy, or sour smell coming from your vents, it’s likely due to moisture buildup in the A/C system or a dirty cabin air filter. Mold and bacteria can thrive in these areas and affect both your comfort and your health.
We can clean out the system and replace the filter to clear the air—literally.
4. Compressor Won’t Engage
If you don’t hear that familiar “click” when turning on the A/C, the compressor may not be kicking on. This could be due to:
- Electrical issues
- Low refrigerant pressure
- A faulty relay or sensor
Our diagnostic equipment allows us to pinpoint exactly what’s going on, so we can fix it quickly and affordably.
