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!!!!"

We offer flexible financing and accept all major credit cards. Call us today and let us earn your business!

"Disclaimer: I was given the opportunity to see cost and options and I did agree to pay for most of the services with the misconception of thinking this type of service is typical cost. However, after I being taken advantage of by replacing a working $5 receptacle and then charged me $77.00. This lead me to do further research and spoke to other licensed electricians. My Story; First let me offer a suggestion, if you don't want see Mr. Sparky's ridicules high cost options that will be over $1000 then don't allow them to do this so-called home inspection. One option was $1,300 to install smoke detectors, mind you smoke detectors cost between $30 to $80 and all you need is a ladder. I denied this option. 1) They installed a so-called home surge protection (Purpose understood) however this small device is just a surge protection device and does nothing to filter or clean variable AC. A device you can buy anywhere for around $200 and 2 std 15-60A breakers which cost between $15 and $40, the job itself typically around 1.5hrs. Cost (high side) should have been around $430, my cost $1,155 2) Installed a new outlet where there was none, cost of outlet $5, typical time maybe a .5 to 1hr depending on how fast electrician would be to run wire. Cost (high side) should have been around $105.00, Mr. Sparky cost $288 3) I stepped out of the house and the electrician asked my wife if he could replace a working receptacle because it had paint on it. Wife agreed. Cost should have been free being part is $5 bucks or $1 and takes 3 to 5 minutes to replace. But ok, maybe cost of $25. Mr. Sparky cost $77.00. No he did not tell us the cost to replace a working receptacle with just paint on it. Typically electrician hourly is $50 $100 an hr. I adjusted my cost on the high side. My total cost should have been a total of around $560, but Mr. Sparky's cost was $ 1,520.00. I DO NOT RECOMMEND USING MR.SPARKY!!!! Find someone who is reputable who doesn't gouge prices to unsuspecting people who don't do research to know they paid too much! It was my mistake, don't let it be yours."

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."

Generator Install questions, answered by experts

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.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

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. 

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.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.
