"Preston and his crew were extremely busy with the fires in the area but still made time to get our project done. They did an outstanding job and did a very clean looking appearance on the home. Overall very pleased and will definitely look to use Eagle again for our future jobs."

"Thomas at Thunderbird Power is fantastic. He KNOWS his trade (a 3rd generation electrician)! Had 2 electricians last year try to fix some broken outlets, after 1.5 hours couldn't figure it out. Another electrician troubleshot it recently and his diagnostic tests ended up NOT being the issue. Thomas had them fixed in 30 minutes and didn't have separate charges for troubleshooting ontop of fixing, just took care of it. He was WAY cheaper than all the other electricians who quoted me in the area for that and replacing all our light fixtures + fixing other issues; I spoke to 6 different electrians in depth about our projects (8 including previous guys). He was the ONLY electrician who did not make a big deal about fans, nor talked small projects into huge ones and needing a second person to help him with all the work, etc. But he did the work in the same amount of time, alone. He was very professional, timely, detail-oriented, neat, and personable (dogs ADORED him). Will hire again!!!"

"

Job was well-planned by the estimator and the guys showed up well-informed as to the layout and modifications that we needed. Estimate was competitive with other companies that we approached. Work was performed efficiently and only delay was a result of a part on the system which was incorrectly positioned by original installer and he to be re-ordered. Jim & Rob were punctual, professional and hard-working and didn't inconvenience us at all.

Generator Install questions, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

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.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.
