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!!!!"

Appliance Doctor is a family owned business that has been in Wichita since 1988.

"I used this company a couple of times when our heating or a/c went out as they were who the original owners had used. They replaced an a/c unit for us when the old one died, but I later found out when it needed a major repair that a) the unit was not under warranty as the installer hadn't sent in the paperwork for it, but that it had been installed incorrectly, was not up to code, and the coolant had not been added properly, causing us to need an expensive repair only a couple of years later that should have been covered by a warranty, but that we had to pay for out of pocket. Also, when our furnace broke, I was informed that the problem was very serious and potentially deadly and would cost $2000 to fix. Something about the exchange just gave me a bad feeling, so I called for a second opinion. It turned out that the issue he had "found" was fine, and that the real problem was a loose screw that was allowing air into the unit. In two minutes a new screw was screwed in and our problem was fixed for $80. We also discovered that previous work that had been done was again no to code/not done properly and had to be fixed. I would not call this person again. We have had far more success with other businesses, and I feel confident that they are doing the job right."

Generator Install questions, answered by experts

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

When properly maintained, natural gas generators can last a long time, as much as 20 to 40 years. They have relatively few needs compared to generators with other fuel types. However, the generator’s lifespan ultimately depends on how often the generator is used and for how long it’s left running.
