The modern suburban and small town home of today has become an ideal lightning target. The home owner would do well to recognize lightning for the destructive force that it is and protect against this major life and fire hazard. Donohue's Lightning Rods is based in Missouri, near the factory where most of the residential and commercial lightning rod supplies are manufactured. Jim travels regularly to Texas, Louisiana, Arkansas, Missouri, Kansas, Montana, Wyoming, Colorado, and New York. Call today to find out when Jim will be in your area. For installations outside Missouri, Kansas, or Texas, Jim waits until there are a few customers lined up, thus being able to provide the same quality services at affordable prices. **WE DO NOT DO ELECTRICAL SERVICES.** (ONLY LIGHTNING RODS)

"The job was beautifully and professionally done. I have a zero scape yard and the gentleman was concerned about disturbing the gravel when putting the rod into the ground. WOW!!!!"

Generator Install questions, answered by experts

Many services include assembling the unit and securing it in the window. Confirm with your provider.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.
