Welcome to Active Cabling & Communications, LLC. We provide the best electrical work for all our residential and commercial clients. We promise to serve our clients with the highest quality and the most convenient pricing.

"I really enjoyed the work by these Networking/Ethernet folks. A different provider had quoted me an $800-1000 project and said I needed Cat 6 cabling for ethernet, when really my existing Cat 5E was fine. All it took was ~$100 and one hour for parts and labor and I now have ethernet ports in every room that support Gigabit speed. Thanks again! Couldn't be happier with this."

Ready to cut the cord, and rabbit ears aren?t cutting it? Cables hanging all over your house, and you want them to disappear? WiFi just doesn?t reach upstairs? You?ve come to the right place! My services include: TV and FM antenna installation and repair, including in attics; old school cable fishing and concealment; installation and repair of coaxial, Ethernet, telephone, speaker, and other low voltage wiring, including repurposing existing cabling; TV wall mounting and cable concealment, especially difficult or unusual locations; limited satellite dish installation, repair, and removal, including Free-To-Air (FTA) dishes. (Sorry, no large C-band dishes, no warranty work on subscription service equipment.) I'm not an equipment dealer, so I won't be trying to sell you anything. I can provide a few items, as a convenience (e.g., antennas, bulk cable), but I?m ready to work with, or advise you on the purchase of your own equipment (e.g., routers, security cameras).

"Ken is a terrific worker and knowledgeable problem solver who took on my old house and my cramped crawl space without even a hint of hesitation or complaint. He worked efficiently and without a pause for more than 10 hours to get a job done in record time----it was much more involved than we thought, and he persisted and got it done, and done right. Thank you Ken! He's a real rarity amongst workmen, absolutely thorough, trustworthy and good natured in the face of all difficulties! A real gem, I'm so glad I hired him!"

Generator Install questions, answered by experts

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.

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.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.

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
