"I was introduced to Sacry through a third party. But I have now found an electrician for life! They showed up with little notice, analyzed the scope of what to be done, and made some recommendations. These recommendations were not so they could charge more, but rather so the job could be completed safely, and look professional. Sacry Electric went out of there way to make sure I was satisfied. I wish more companies had the same values as Sacry, putting the customers wants, needs, AND budget as their only priorities! Thanks again Sacry! I will be calling again soon!"

"They did a great job and fixed my mast on my house. The only thing I am questioning is the time they spent doing the job. I was unable to get into Angi for the time they were coming, so I had not called NorthWestern Energy to get the power shut off. I was charged for 3 1/2 hours."

Generator Install questions, answered by experts

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.

The cost to install a whole-house generator averages at $5,200, but costs can range from $1,500 to $8,900, depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don’t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.

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.

Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.

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.
