"New to the area, I needed a hookup for an emergency generator and EV charger. Cole came to my home, took the time to discuss different options and answer questions, and provided a detailed, written estimate, all the same day as my initial inquiry. The project was completed within a few days. His price was very competitive and his work meticulous. A true professional."

"He made room in my electrical panel by installing double circuit-breakers to accommodate my home. Based on the work and how they presented themselves, I would recommend them. Very clean and professional, and I would hire them again in a heartbeat. Their price was reasonable, the work was great, and it was an overall pleasant experience."

"Jack and his crew were extremely knowledgeable, helpful, and a pleasure to work with. From running new wiring into an existing ceiling for ceiling lights, upgrading my elective panel, installing ceiling fixtures, and installing new outlets, Jack and his crew were able to perform the tasks efficiently and Iâ m very happy with the outcome. Wilburforce was also more affordable than other electricians in the area. I would highly recommend this business and I will be using them again."

"Ryan is awesome! We needed to upgrade our garage electrical + smoke detectors & pool alarms @ our rental property in L.I. (Permit dept requirements) Ryan arrived right when he said he would & he stayed extra to help ADT solve a new thermostat issue. He texted us pics of each repair/replacement he did before he left the property. He gives good & honest advice, & is very easy to work with! Other electricians we contacted for this last minute project didnâ t even bother to get back to us! I highly recommend RCK Electric."

Generator Install FAQs, answered by experts

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

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.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.
