This allows me to use our 7000 kw generator to operate the well, booster pump and other circuits. Testing went very smoothly and they explained the operation in detail. A great price as well."

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)

"We were contacted immediately regarding adding a lightning protection system on our home. Seamus was very thorough and knowledgeable regarding our concerns. He and his crew showed up and were very professional and efficient. We are very pleased with the installation and highly recommend Donahue’s."

Generator Install questions, answered by experts

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
