"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

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

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.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
