"Electrician had professional appearance and work ethic. Job was not easy due to the new RG6 cable was required to be installed in the flat roof area of the home which is a very confined space to maneuver. Arrived on time as promised, but unfortunately the cable used was not adequate to transmit the new Spectrum digital signal and the following day I had to have the newly installed cable (which was a copper cladded RG6 cable) replaced by a steel cladded RG6 cable in order to receive the Spectrum signal. I attempted to alert the electrician that due to the recent change of Spectrum from an analog signal to a digital signal on April 17th 2018 that he needed to use a higher quality RG6 cable or he would continue to have unsatisfied customers. Electrician has failed to return my call which is unfortunate for him as I think his work was excellent, but his future cable installation jobs may be rated less than excellent if the quality of cable used is not resolved."

Generator Install FAQs, answered by experts

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

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

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.
