When we opened our doors almost 10 years ago, our objectives were clear: carry the finest equipment; offer liberal and straightforward policies; be big enough to provide extensive services and competitive prices but small enough to know our customers. Since 2002, PS Production has made great strides, our industry has been transformed, and we have championed these advances. Through it all, however, the human factor has remained constant. Our customers have not become �digitized� and neither has our way of doing business.
"Mike was great to work with. He answered all our questions and did excellent work!"

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 installations FAQs
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
