"They did a good job.  I got them from Angie’s List.  The price is a little high but they did good work.  They were very nice.  I am pleased with what they did."

"I ended up hiring someone else who could install a ceiling fan as Paradise Construction was afraid of needing to tear up a large section of the ceiling and I didn’t want to create additional work and expense."

"Very professional service.  The sale person came to verify the scope of work and provided us with a detailed quote. We scheduled the installation soon after. We had only a minor issue, becuase when the technical crew came in they realized that more work was needed (but no change in the quote). We rescheduled the installation a week after and everything went very well. The sale person remained our point of contact before, during and after the installation and he performed a follow up visit to make sure everything was fine. The technical crew was also very professional.  I would reccomend them for sure.

"It went very well.  Tony is very responsive, courteous, and goes out of his way to make things convenient for the customer.  Not only is he very competent and thorough in his work, but he also  did a lot of the leg work, picking things up at the electric supply store, returned a couple things that I had incorrectly purchased there in my own trips prior to hiring him, and even went there on my behalf for a bed lamp that needed a new contact.  He disconnected it, brought it to the store, took a trip back to the store a week later to pick it up, and reinstalled it for me.  Tony could have applied a trip charge for each of the many visits he made to my place but didn't.  He also took the time to explain options, solutions, and even gave me a bit of free schooling in electrical work.  I highly recommend him and his business.

Generator Install questions, answered by experts

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.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

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.

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.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
