"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."

"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."

"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."

"The work went great. A representative looked over the situation ( a 3 story townhouse), decided it could be done and gave us a solid price. The two person crew who did the work were punctual, efficient and neat in their work. The detectors and wiring was installed with no damage to the paint. The job took them about 3 hours. My wife and I were very pleased."

"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."

"⭐️⭐️⭐️⭐️⭐️ Excellent Service – Highly Recommend! I had an EcoFlow panel installed in my home, and I am extremely pleased with the electrician’s work. From start to finish, the process was smooth, professional, and well organized. He was knowledgeable about the EcoFlow system, took the time to explain how everything works, and made sure the installation was done safely and neatly. The wiring was clean, the panel was properly labeled, and everything was tested thoroughly before he left. What I appreciated most was his patience and willingness to answer my questions. He made sure I felt confident using the system before completing the job. His professionalism and attention to detail truly stood out. If you are looking for a reliable and skilled electrician for EcoFlow or backup power installation, I highly recommend his services. I will definitely use him again in the future"

FAQs for generator install projects in Lothian, MD

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:

  • Portable generators with 1kW–7.5kW capacity: $500–$2,000

  • Partial generators with 9kW–20kW capacity: $2,000–$6,300

  • Whole-house generators with 22kW–48kW: $5,000–$18,000

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:

  • Experience frequent or prolonged power outages

  • Work from home

  • Store a lot of cold food

  • Have a sump pump

  • Have a pump for well water

  • Use electronic medical devices

  • Live in a climate requiring heating or cooling
