"We hired Cameron to install three ceiling fans in rooms that did not have existing overhead lighting. He was very professional and courteous, and he did a great job with the installation. From the estimate to the finished job, we were impressed with Cameron's expertise. The estimate we received was accurate with the final cost which was very competitive and reasonable for the work performed. We would highly recommend Ross Electrical Contracting and would hire him again."

"Tom was great at installing my RV outlet. Out of the 3 different quotes I received, he was able to get it done without trying to talk me into more expensive options. He was also accommodating with my somewhat busy schedule and very responsive throughout the install planning process. I would highly recommend Productive Electric."

"Precision installed my water heater two years ago. When I had my furnace serviced, the technician checked the pressure on the water heater and it was very high, a component had failed. A plumber from Precision came out and replaced the defective part since it was under warranty. He suspected that a water pressure regulator may have to be installed but when he checked the water pressure coming into the house, it was in the acceptable range. He could have just as easily told me I needed this and it would have cost me $600 but Jacob was an honest man. I am so impressed with his integrity. I will use them again in the future for sure. The replacement of the defective part didn't cost me anything. Thank you Precision for being an honest company."

Generator Install FAQs, answered by experts

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

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.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two.
