"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

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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.
