With over ten years of experience, I have a diverse skill set with a vast array of gifts and talents. From minor repair work to major residential renovation and remodel, I have done it well. My company is licensed, bonded and insured. I perform work for both residential and commercial clients. If a job happens to be outside my wheelhouse or if I think you will be better served by someone else, I will be sure and let you know. Above all else, I strive to deliver superior work while treating my clients with the utmost respect. Please contact me. I look forward to speaking with you regarding your needs and serving you well. At the end, I want you to feel, "I'm glad I worked with Paul!"

"Had some trouble with an outlet that turned out to be some internal wiring issue. Paul worked to diagnose and fix the issue. He also helped resolve some other minor issues I needed help with along the way. Very glad to have the primary issue quickly resolved, and the other tasks taken care of. I enjoyed meeting and talking with Paul, and would recommend and rehire for future projects."

"David was very no-nonsense, quickly assessed the problem and resolved it for a reasonable service call fee in about 20 minutes. He was thorough and professional, and Juice Company will be the first ones we call when were ready to do additional work. This was in contrast to another company who spent two hours giving us a hard sell on a complete overhaul of our home's electrical system but never got around to fixing our immediate issue."

Generator Install questions, answered by experts

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.

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

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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. 

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.
