In 1993, Tom Raynor began taking on electrical construction and service jobs across southern New Jersey. With just one assistant and one beat-up truck, Tom crisscrossed the state, building a reputation for his small outfit as one that offered professional, hands-on service and reliable, high-quality results. By 1994, it was official—Raynor Services was born! \n \nSince then, that red pick-up has been upgraded to a fleet of ten fully stocked trucks. We are now a “one-stop shop” service company, specializing in electric, heating, cooling, and generator services. Raynor Services has never lost the spirit of professional, hands-on service that it was founded on. Family-owned and operated, we combine small-business service with big-business expertise. \n \nRaynor technicians are among the best in the industry. Each must complete a rigorous hiring process – including a background check, a drug test, and an HVAC or electrical proficiency examination.

Generator Install questions, answered by experts

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

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.

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. 

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.
