"Excellent. Came and gave me an estimate and that is the price he charged for installing a new dining room light. Very neat, picked up after himself and had great communication skills. Would hire again without reservation. Highly recommend."

"We needed a meter pole for our RV, and Marty's gave us a very reasonable quote, as well as a full detailed estimate of the job to be done. They installed our meter pole exactly to local city/ state codes, and completed it in a very timely manner! We could not have been more pleased with the project outcome!"

"Everyone from the start of working with this company was great. We had solar panels installed back in 2022 and the company then they went under federal control. I had called multiple companies, no one was willing to help except your home solar. We needed a permit to get the solar up and running which also meant the state inspection. Anita, Landon and all of the other employees that we encountered in this process made it a very easy process. I would recommend this company to anyone looking for solar or that needs to get panels they have up and running."

"I only rated them a four for quality for now as they just started work. So far this is an awesome company, very professional and nice people. The return calls or emails in a timely manner and fair on pricing. Besides having a generator install, ( which is back logged due to high demand since recent hurricanes), I have a side project that they are currently doing. I recommend this company."

"I had a car charger installed and was really happy with the work. He was responsive, showed up when he said he would, and the install came out clean and professional. Everything was explained clearly, the work area was left neat, and the charger works exactly as it should. Definitely someone I?d recommend if you need electrical work done."

Generator Install questions, answered by experts

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.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

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.
