Common Generator Issues in Pasadena, TX
Generators, like all mechanical systems, experience wear and tear that can impair their functionality if not addressed proactively. Pasadena’s humid subtropical climate can accelerate corrosion, battery deterioration, and fuel system problems, making routine service even more vital. Here are some frequent generator problems we encounter and resolve through expert maintenance:
- Battery Failures: The heat and humidity in Pasadena can reduce battery life or cause corrosion on terminals, leading to failure to start during outages.
- Fuel System Contamination: Ethanol-blended fuels can absorb moisture, causing clogged fuel lines or filters.
- Oil and Filter Degradation: Heat stresses engine oil and filters, reducing their efficiency and risking engine damage.
- Cooling System Malfunctions: Radiator leaks, coolant loss, or clogged radiators can lead to overheating.
- Transfer Switch Problems: Faulty automatic transfer switches may fail to switch power from the grid to the generator, causing outages to last longer.
- Load Testing Failures: Without regular exercise and load testing, generators may falter under full electrical demand during real power interruptions.
Understanding these possible issues highlights the importance of entrusting your generator to the skilled professionals at Mackey Services for regular maintenance.
