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

No, you cannot plug a generator directly into a wall outlet in your home. Plugging in a generator without an interlocking kit, extension cord, or wall outlet receptacle is incredibly dangerous and can cause back-feeding—power from the generator back-feeds into utility lines. Also, if the main power comes back on while your generator is on, it could damage the generator and cause a house fire.

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.

The cost to install a whole-house generator averages at $5,200, but costs can range from $1,500 to $8,900, depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don’t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.
