Excessive Vibration
Some vibration is normal; strong shaking indicates issues

Drop in Performance
Signs: slow pressure build-up or failure to reach required levels
Causes: worn valves, air leaks, motor problems
Quick Check:

Rising Energy Bills
Poor condition → more energy to deliver same output
Causes: clogged filters, leaks, mechanical wear
Quick Check:
● Track monthly electricity usage

Overheating
Hotter-than-usual compressor = possible blocked airflow, dirty cooling, or motor issues
Quick Check:

Quick Check:
● Look for oil spots/puddles
