"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."

"We hired Alex to install a manual transfer switch for a generator. Alex is very skilled, knowledgeable and professional. We had nothing short of a great experience beginning with the initial estimate to the install. Install was quick, efficient and CLEAN. We 100% will be hiring Alex again for future jobs! If you're looking for a reliable, trustworthy electrician, Alex is your guy!"

"Installer did a good job on installing ceiling fan with light kit. He was friendly and cleaned up after installation. Still working well 2 months later. The only things disappointing is that my initial phone quote was about $100 less than I was originally charged. I'm not sure if the difference was the labor I was charged to assemble the ceiling fan.

Recently, I was contacted by the Frederick Manager, Lou and he took care of my concerns. We discussed future job opportunities in my home. I would recommend this company for their good work and customer service."

"Provided guidance and direction in lighting layout, helpful choosing placement and quantity of lights, on-time, and cleaned up after installation. Reasonably priced, and mindful of working clean while entering and exiting my home. Very respectful. Planning to hire again and will definitely keep or refer this contact."

"Local company with two master electricians with over 22 years experience and with the owners son proving to be a strong electrical apprentice. i liked that the owner is a master electrician who personally conducted the free appraisal and would also be working with his men. He was very personal and attentive. Every detail was reflected in the appraisal. When his other master electrician arrived on day one it was clear he understood every detail as if he had conducted the interview. They used generators to support me teleworking throughout. I highly recommend this team for panel and all home electrical upgrade."

Small jobs welcome

"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

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

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

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.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.
