"Mario and his crew did an excellent job with my barn wiring and lighting. They took a two or three day job and made it a long single day effort. Their work is clean, measured and professional. The guys are friendly and skilled. Definitely going to have them do some additional work down the road with an RV garage and whole house generator install."

"Garth and Andy from Ponderosa Electric came to my house and reviewed my projects. They were very knowledgeable and had great ideas for me. They directed me to Home Depot and who to talk to there for my supplies. They are coming back to do the work next week. Although Garth had a medical issue and couldn’t be here, Andy was very capable. He installed all lights, tested them, made sure I was happy, and cleaned up any mess. He was polite and professional. Even though he was working solo, he assured me he would take whatever time was needed to get the work done correctly, and he did. I am very pleased and would recommend them."

"Great job mounting my lights. Helped remove an old solid wood 70’s box light. Had some issues getting the living ceiling fan installed. My previous fan had one switch for the fan and one for the light. I guess the wiring is old and incompatible with this new fancy fan. So now one light switch turns the fan and light on and the other switch that controled the old fan does nothing. Thankfully the fan can with a remote control so I use that to turn the fan on and off and it works just fine as a work around. I am very happy with the service provided and will use them again."

Generator Install questions, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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.

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.

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.
