My company has been officially registered for two years, but we have six years of experience in painting and remodeling. I also have cleaning staff. We are professionals in our work, and I had a large painting project nearing completion, so I'm looking for new opportunities as a subcontractor.

"I was sent a quote for $390 and accepted the quote online. After that, the office changed the quote to $499 - AFTER I accepted $390 for the work! Then, after the work was completed, the worker went to his truck, called the office and came back in saying, **I am the bearer of bad news, the cost is actually $666!**I called the owners and nicely asked if we could talk about this, and the owner basically said that their prices are **fluid** and that the bill had gone up! I tried explaining that I had signed a quote for $390, but she then threatened to put a lien on my house if I didnt pay the $666. I would never use ETD Electrical Services ever again."

"The technician came late on Friday afternoon to repair an electrical outlet. Everything seemed to go perfectly and the technician indicated that he was on call Saturday. An hour after he left I tried to start my dishwasher which has worked fine for the five years that I have lived here The dishwasher seemed to have no power and is about two feet from the repaired outlet. I have not been able to get a phone call response in 24 hours. I at least expected a return phone call "

Generator Install questions, answered by experts

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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.

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.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.
