We have provided hometown service to residents of the Kansas City Metro since 1951. We offer FREE ESTIMATES on a new air conditioner, furnace, boiler, heat pump, geothermal, zoning, water heater, tankless water heater, plumbing remodel projects, and battery back-up sump pump.

"James was fantastic! He was polite and knowledgeable. He efficiently fixed our air conditioning, and informed us of all the different options we had. We will certainly use this company again if James is any indication of the caliber of staff they employ."

"He killed my tree. I'm pretty upset by that. He also obviously didn't listen when going over what I wanted done and charged me extra for an area that was already supposed to be part of the estimate. I ended up doing 75% of that area myself. He's a really nice guy but I feel like he over extended himself with work and overlooked several things. We discussed him leaving a plant I wanted, he pulled it up as well. Not the worst job but certainly won't hire again. "

Rick's Handyman Services, LLC is here for all your handyman and appliance repair needs! No project is too small or large. Give us a call for a free estimate on your project!

"If I could give this guy a zero rating I would. He came 2-19-20 to give us an estimate on our failing toilet and drippy faucet. He was coming yesterday, 2-21-20, to do the repair at 3:30pm. My husband took the afternoon off work to be home. At 3:40pm he still was not here, so I called him. He told me I should **get someone else**. He comes across as a **good old boy** and will talk your leg off. Even about other customers. He drives a retired vehicle and I would think would have ample room to stock normal plumbing repair parts such as a toilet fill valve one would think. Unreliable. Move on from him is my opinion. My husband was so mad he watched online videos, and did the necessary repairs for $20."

I am a locally owned and operated company that takes great pride my work. I specialize in bathroom remodels but have many years of experience doing electrical and plumbing work as well. I pride myself on the quality of my work and well as my commitment to outstanding results. I look forward to speaking with you about your remodeling needs and building lasting relationships with my clients.

"I hired Todd to reconstruct a medium sized, dilapidated workshop structure on my property to be used as a candle making studio. I had confidence the building could be improved upon but was not exactly sure what to expect. The tin roof was caving in, the building had fire damage, and it was structurally "askew." Todd started with the the side of the structure with the most damage. The results, thus far, are amazing. The side he is working on looks nearly brand new. I am not only impressed with his attention to detail and craftsmanship but also his willingness to articulate his ideas, processes, and techniques. Finally, his time management is outstanding. I have worked with other craftsman in the past and although they might have done great work, showing up on time wasn't always the biggest priority. I highly recommend Todd for any handyman+ job and more! :)"

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!!!!"

Generator Install questions, answered by experts

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.
