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!!!!"

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

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. 

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.
