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."

"The pro quickly found the electrical problem..but said anopther appt would be made to repair. I remember the initial information was..if the repair can be made then..that would be done. However the pro then proceeded to go thru my home and look at plug ins, alarms, etc. I really didnt know why other than he said part of their visit was to be sure the home was safe electrically. He then gave me 3 proposals of things my home needed. The most extreme was 29.000$. I I said all I wanted was the 1 problem fixed..he told me that would be $1089! Again I was stunned at the high price to repair. I certainly should have said No thank you and end the process. But I needed it repaired. It was scheduled for the next day. It did take a longer time for the repairmen to arrive..said GPS problem. He finished the repair in a good time..but said he didnt have anycaulk/sealer to put around the outside receptacle in his truck. I would consider that item an easy needed product to have on the truck."

Home Performance Group is a mechanical, electrical, and plumbing firm providing service and maintenance for residential Heating and Cooling, Electrical and Plumbing systems, as well as appliance service and general mechanical repair for homes. Our installation team specializes in design, engineering and installation of cutting edge green technologies such as ground-source heat pumps, heated floors, PV solar arrays and much more.

"On 12/24/22, Home Performance Group sent a gentleman to inspect my attic for faulty ductwork since exhaust fans weren't venting correctly. The gentleman stated the issue was significant and would require two laborers. I relied on this representation and agreed to pay roughly $900. Two laborers came to my house on 12/29. They finished the project within 45 minutes. They asked for the remaining balance, which I paid. At the same time, I stated I felt taken advantage of and would contact their office. The office manager confirmed their wage rate is $150/hour/laborer. Thus, labor cost was roughly $300. I asked for materials cost and they refused to provide this amount. Given typical ductwork cost, I imagine materials cost was de minimis. Even with reasonable OH&P, Home Performance Group should have revised their bill by roughly $500 to reflect how quickly they finished the job. They have refused to do so. Without equivocation, I feel they misrepresented the severity of the project and took full advantage of the consumer."

FAQs for generator install projects in Agency, MO

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.

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 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
