"We are extremely satisfied with our generator purchase. We interviewed several different companies and Alternative Home Energy and Maintenance was the only firm that understood our needs. They did a thorough review of our electrical and gas configuration on the initial sales call, which none of the other companies did. We were provided a detailed, line item quote. The entire team - Tasha Thompson, Jarrod Watson, Robb Taylor, Zack Martin, and James Sanders (plus a couple of other individuals whose names I don't have) were top notch. Tasha did an outstanding job in keeping us informed every step of the way. Robb did a thorough walkthrough and was a no-pressure sales rep, James and Zack did an outstanding job on the installation. I can be pretty high maintenance on jobs like this and Tasha was incredibly responsive to my texts and emails. I can't recommend this firm highly enough. A lot of folks will sell you product, but this team delivers value and customer service at a very competitive rate. Great job, team!"

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 man who did the job were awesome. They were very thorough, professional, and speedy. They left our church grounds spotless. I could not recommend them highly enough."

"We had lightning rods installed at our home after having 2 previous lightning strikes. The first strike was minor, with only slight damage in the yard. The second was significant when a very large pine tree was hit close to our house causing various electrical issues in the home -- despite having a whole home surge protection system. Just months after having the lightning rods installed, lightning struck an even larger pine tree in our small back yard, Thankfully, the lightning rods saved us! It was a huge strike, and we had no damage at all in the house. These lightning rods were potentially life-saving."

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
