"L I put request on Home advisor/Angie's list. Out of all the request this is the only company that responded to my request. Not only did he respond within 30 minutes, he came out the same day, installed my ceiling fan, and finished everything up within one hour. Most kind efficient, professional, and very knowledgeable company. I would definitely use them anytime and every time. Thank you so much, Kevin."

"I contacted Mr. Denny for a whole house generator that would not stay running and it had been down for a year or so. Once the weather cooperated he came to the property and did the repairs in a very timely manner. We were kept in the loop and the repairs needed were explained. We were happy with the work and communication with Mr. Denny and would recommend him and his company. We look forward to working with them for many years to keep our generator in tip top shape! Thank you again!"

"Things went well. Russ Piper came out and met with me - to see what the project entailed. Meeting went well, I fully understood what they were going to do. I got a quote back quickly and moved forward with it.   When the plumber (Plumb Crazy)came out to see what needed to be done, I had some options .  I decided to have a higher service line brought into the home - now BGE is involved.   Without further stories - it took many weeks to get BGE to install the higher service, Throughout, this process, Benfield and the plumber where checking in with me for progress.  And when the inspections where all complete - they came right out and finished the installation."

Generator Install questions, answered by experts

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local 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.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
