"Installation went well. They were patient with me as I explained exactly what it was I needed. After the installation, the fan vibrated very loudly into my bedroom. I called to have this fixed, and the work was done in a few days with no additional charge. The fan has been working well."

"Everything about Able Electrical Services service was superb! I was in a jam, and Able Electrical Services came to the rescue. Both of the mechanics that assisted were excellent. Russell Ridgway was the primary mechanic and he was amazing! His work is superior and he exceeded my expectations every step of the way. For example, I needed electrical outlets to connect install a wet bar. He measured the wet bar and installed the outlets exactly where they were needed and ensured sufficient power was added to accommodate a kegerator and mini-frigs. I highly recommend Able Electrical Services and hope I never need to use any other electrician."

"The RaLo electrician did a great job running new wire to install my outdoor camlight. He also informed me of a number of other issues he noticed and gave me good price to address those issues as well. I definitely recommend their services."

"It was AWESOME. I've used Chesapeake Energy Solutions twice... Both times the experience was outstanding. The staff were very prompt, and professional. Very polite and courteous. I was amazed at their level of competence, expertise and knowledge of their craft. They came in, and were troubleshooting and knocking out issues faster than I could keep up with.. They finished all that I needed done, before my time expired. How incredible is that..?? I was truly impressed. I used them a second time, on another occasion, to install a ceiling fan, and once again, I was blown away by a phenomenal job. The technician put down tarp on the flooring to protect my beautiful hardwood floors. Before feeding the wires thru the walls, he took care to cut nice, clean openings in the walls. (I appreciated the fact that he saved the perfectly cut pieces for me, to be reinstalled later... ) Upon completion, he did a superb job of vacuuming and cleaning up the area. He left my home as he found it. I would highly recommend Chesapeake Energy Solutions to anyone that needs proficient, lightening-speed, service. Ryan and his crew are "on it" and are masters at what they do. They genuinely know their stuff."

Generator Install questions, answered by experts

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.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

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.

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.
