"The Serviceman was on time. I had questions about the humidifier, which he answered thoroughly. He corrected a small issue with the A/C and the circuit breaker box as well. He went over the entire install from A to Z. We feel safe and secure with the knowledge that absolutely nothing was overlooked."

"Jordan Blake from Exceptional Electric rocks! His communication prior to coming out was very thorough, and he was able to schedule us in two days. While he was onsite he found multiple items from years of DIY wiring, one major one. He clearly communicated al recommended changes to better match current code. As to the major item, he discovered the transformer was causing over-voltage delivery into our main! He had me call United Electric, and the linemen were out even before Jordan left – kudos to U.E. Cooperative – and replaced the transformer on the pole. All this for what started out as just putting a new 30A circuit in for a mini-split! Our mini-split is not yet on site, so we look forward to having Jordan back to the farm to complete the electrical plus a couple of the found issues next week. He is so knowledgeable. I highly recommend him. His sense of humor is also a delight, and my husband enjoyed learning and discussing many things with him. His prices are excellent."

Generator Install questions, answered by experts

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.

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.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.
