"Mr. Holtzclaw is an extremely professional, friendly, and HONEST individual. He came to my home and went right to work, explaining to me the work and the issues he confronted all of the way through the process. When he completed the project, he charged a very FAIR price which was lower than I had been quoted by bigger operations for the same work. I highly recommend Holtzclaw Electric."

"This was no simple project, it was necessary for several fixtures to be moved and a cabinet to be made to fit. We are a Public Library and are only open a few days a week with specific hours. In addition to this project, he has installed a light fixture in the ceiling, an emergency light, a smoke alarm and added a bookcase. Neil was able to work around our hours and install smoothly without disturbance to patrons inside. The work area remained clean while he was working and he followed through the complete job in a timely manner. He knew what tools he would need and came prepared. I have him on the agenda for more work in the future. The range of his skills allows for the Library to utilize his business for multiple projects in a wide variety of areas. The cost was wonderfully in our budget and he is able to give quotes immediately. Love working with him."

Generator Install questions, answered by experts

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

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.
