"The solar installation went fantastic, but once the battery was added to the mix things went south fast. The battery was a Franklin and they had never done one before. So, I was happy to be patient till they could resolve it. But after 21 days the system is still not functioning properly. There was a holiday in there and I am happy to write off one week but surely within two weeks and two missed appointments, there could have been a resolution. I even went as far as to reach out to Franklin myself and they told me what was wrong from their perspective, and I did research on the web and via Grok. I think they are just too busy to support the workload they have."

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)

"We were contacted immediately regarding adding a lightning protection system on our home. Seamus was very thorough and knowledgeable regarding our concerns. He and his crew showed up and were very professional and efficient. We are very pleased with the installation and highly recommend Donahue’s."

"Working with the Mr. Electric team was a pleasure from start to finish. We had a laundry list of fixes and upgrades we wanted to perform, from the mundane (adding light switches and outlets) to the exotic (setting up niche smart home device relays). Mr. Electric gave us an itemized price list so we could pick what we wanted at this time and have a reference for the rest later. When we had decided what we wanted done, they were very accommodating on the total price for the services requested, and I feel like I got a great deal on a very professional outcome. Along the way, their communication was stellar. They sent a text message before each appointment to let us know they were on the way (never late, I might add), and the text even had a picture of the technician coming out so we knew who to look for. Working with Ben was seamless, and he acknowledged our requests and made suggestions where relevant. In the end, I got great communication and great work for a very reasonable price. If I have any electrical needs in the future, Mr. Electric will be the first call I make."

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

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.

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. 

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

In many cases, you’ll need a permit or basic inspection to install one of these large generators. Since they include significant alterations to your home electrical system and many produce exhaust fumes, local governments often require jumping through a few hoops for general safety purposes. Your installer may be able to help you with these permits.
