The Importance of Generator Maintenance
All mechanical equipment needs preventative and corrective maintenance, including Generators. It's just a fact of life. Which is why you should protect the equipment that protects your home and family.
Oil and filter changes, cleaning (inside and out), testing and calibration, all by a trained eye, should be a part of the annual maintenance of your generator. Failure to do so will absolutely decrease reliability and void your manufacturer warranty.
SOJI Power Solutions can handle all of your residential and commercial generator maintenance and repairs. Learn more about our comprehensive service plans below.
