"⭐⭐⭐⭐⭐ I had an excellent experience with Max from Amex Electrical for my home electric vehicle charger installation. From start to finish, Max was professional, knowledgeable, and extremely efficient. He explained the entire process clearly, made sure everything was installed safely and up to code, and answered all of my questions with patience and expertise. All materials were provided, and the quality of the work was outstanding. The installation was clean, neat, and completed in a timely manner. It’s clear that Max takes pride in his work and truly cares about customer satisfaction. If you’re looking for a reliable and skilled electrician for EV installation at home, I highly recommend Max and Amex Electrical. Five stars all the way!"

"Triton electric truly deserves a five star rating from me. Triton first completed lighting work for exterior of THE GYM last year and it was done efficiently and exceeded our expectations on timing and professionalism. Over the last 2 months we have begun renovations and a new construction project here at THE GYM, Triton electric was our first choice. From the initial quoting of the job, to the installation, to the consulting with our architect and contractors, Triton has been extremely professional, communicative and reliable. Thomas’s whole team have been a pleasure to work with and we as a company would highly recommend and continue to use them for all of our projects going forward."

"I hired Richard and his crew to install a generator for my daughters new home. I was very impressed with the workers they sent to my home, probably the friendliest contractors I've ever met. They completed the entire install in two days. I would definitely recommend Albright. Thanks guys!"

Generator Install questions, answered by experts

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

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.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.
