Use your eyes and ears to tell when your generator needs replacing. The following are five signs you may need a new generator for your home:
Residential propane backup generators are supposed to last for at least 12 years. The older the generator, the greater the likelihood that it needs to be replaced.
Frequent, excessive repairs indicate that your generator is failing.
Difficulty starting your generator suggests that it may need to be replaced.
High fuel consumption is common as generators start to wear out.
