"Tim gave us an honest evaluation of our existing water heater and options for repair or replacement. We decided to replace the water heater and Tri-State scheduled the next day. Installation was professional and l think Tim is the kind of craftsman you want representing your organization. The fact that you install the Rheem brand helped close the deal."

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

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

As long as your generator is used as recommended by the manufacturer, it’s safe to use for auxiliary power. Make sure that fuel powered generators are used outdoors and that the fumes dissipate away from your home. A professional generator installer will ensure your generator’s placement and set-up meets safety standards when installing or repairing your back-up power source.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.
