Standby Generator Maintenance



It's not uncommon for a standby generator to have a lifespan that ranges from 2,000 to over 15,000 hours. If you think about it, backup generators are typically used as little as 30 hours each year (based on typical 5-15 minute cycles each weak and assuming no outages during the year), but can be used as much as 100-300 hours per year depending on the number of outages. Regardless, your backup generator should have a great lifespan that can last 20-30+ years! However, your generator is no different than the family car. It needs an annual inspection, regular oil changes (annually), battery replacement every 4-6 years, new air filter(s) every 2-5 years, sparkplugs every 2-3 years, etc. Newer units also require firmware updates, regular adjustments and load test regularly. Not maintaining your generator, you are definitely setting yourself up for potential problems. Call to day for offers, and let us Protect Your Power.
