"I am truly impressed with the quality and professionalism of BN Electric! I received immediate phone and email responses to my initial Service Magic request...and an appointment was conveniently set up for the next day (a Saturday!). All work was not only fully explained and completed cleanly and efficiently, but with true pride in a job done right! Butch and Chris were very friendly and stuck to the original quote even though the job required a bit of extra unexpected work. I will definitely be using their services in the future and will recommend them to anyone in need of electrical services! Thank you, Butch!"

The problem with most "pros"? Too many bad habits.\nIt's easy to get swept away in the day to day monotony, even for those that call themselves "pros". When it comes to hiring a heating and cooling technician, nobody wants to deal with being treated like a sale rather than a person, the use of scare tactics instead of education, or someone who just wants to get to job done quickly instead of correctly. \nAll our HVAC pros go through 5 years of HVAC schooling, for a total of 10,000 hours of on-the-job training. And it's not just technical training either; it's training that focuses on you, on making you feel comfortable every step of the way. We will roll out the red carpet for you, both figuratively and literally.\nRed Carpet Treatment\nDuring every visit to a home, we lay out an actual red carpet to prevent any additional mess. But what may be even more important than just protecting your home is making sure you feel like you've received the best in customer service.

Generator Install questions, answered by experts

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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.

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.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Costs range from $500 to $2,500, depending on generator type and installation complexity.
