"Great service and both Brandon and his coworker were professional, prompt and courteous. I rated customer 4.5 only because for the generator install he had forgotten to tell me I would need gas lines run, which increased the price 450$."

"Klaus, owner of Resolute Electric, showed up initially to complete the estimate. Klaus was on time, professional and left us feeling we chose the right guy for the job. Klaus provided an estimate within 24 hours, we scheduled the date of the installation and Klaus arrived exactly when he said he would be there. He was very knowledgeable about what needed to be done, did not hesitate to get started and completed installing the flood light in exactly the area we wanted and removed power to the base board heating at the junction box. The flood light needed to be hard wired and Klaus was nothing less than stellar from the moment we met him to the time he left after completing everything we requested. Resolute's pricing is very fair and anyone that uses Resolute will 100% be satisfied with the price and work performed."

Customers say: True professional

"I would like to thank Crest Electric and their team for the work they did at my new home. We recently purchased a house in DE, and being new to the area, it was a relief to find a fair and reliable contractor who takes pride in their work. I needed their help with installing recess lighting, raising the electrical outlets, mounting TVs with TV mounts, installing chandeliers, and handling the installation of doorbells, cameras, and floodlights. It was such a relief to have Crest Electric manage this huge project, and they offered a reasonable price without making me feel like I was being ripped off. I highly recommend Crest Electric for their attention to detail and their willingness to make adjustments to ensure that everything is perfect in the eyes of their clients. This is something that a lot of contractors take for granted, but Crest Electric truly understands the importance of meeting their client's needs and preferences. -Michael"

Generator Install questions, answered by experts

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

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