"We hired Absolute Electric to install a brand new bathroom fan, new light switch, replace GFCI sockets, and install a Nest thermostat.

"The logo on one of my many Snell repair receipts says, “Snell . . . The Stand-Up Guys.” Wherever Snell is “standing,” it most assuredly is not behind the products they sell or the services they provide. Snell installed a complete AC system at my house in 2013.* We enjoyed only 3 years of uninterrupted use. After that – and literally thousands of dollars later – I’m told I need an entirely new system. Snell’s handling of the situation has been absolutely miserable. The most basic set of facts are: 2013: $8,400 installation; 2016: $769 repair; 2017: $916 repair; 2017 repair (no charge); 2019: $1,508 repair; 2020: $2,400 repair or $8K+ replacement system needed. At each repair, I was simply told “they just don’t make things like they used to.” They encouraged me to consider replacing the system as early as 2019, i.e., 6 years after they installed it. The compressor they installed in 2019 failed after only 13-months. They shouldered absolutely no responsibility at any point and offered no concessions. The repair prices I quoted above were the result of me calling the manager and demanding accountability. Snell’s game plan in each instance was to blame the product (they recommended), blame the customer (“you haven’t changed your filters” … yes I have, religiously), and always be selling (“you should consider replacing the system”). It’s exactly the type of response you would expect from a company owned by a private equity firm, which Snell now is. The installation was botched from the start (e.g., installing a 4-ton, when I really only needed a 3-ton, etc.) and my conversations with other companies since firing Snell has reinforced this and more. *After studying my receipts to write this review, I see now that I was sold a “20 SEER” AC, although a 17-SEER AC was installed instead. At this point, I’m just disgusted. “They just don’t make things like they used to.” No, they sure don’t, Snell, they sure don’t. If Snell responds to this review they should address (1) when they will refund my $3K+ in faulty repairs, and (2) the discrepancy between my receipt and what was installed."

We are a family owned and operated business that has been serving the Baltimore, Washington Metropolitan area since 1925. We are committed to providing superior electrical services. The valuable advantages we can offer you are great service, high quality and experienced workers at a competitive price.
"Do not use this company. They will rip you off. The contract was for eight 300W LED 40 ft pole lights, but I caught them redhanded installing 240W. Who does that? Then, they broke my lock and broke into my sprinkler room which I saw on my video which they admitted. Then, Kolb sued me for not paying the bill which I disputed due to lost tools as result of the break-in. Who does that breaking into a customer's sprinkler room and not informing that they did. I had to catch them on my video. Not only that it took over one year to the work proposed work. TOTAL FRAUD. I will be going to court...."

Many people believe that their car is the largest single source of air pollution for which they are personally responsible. But in fact, the average home causes the emission of more than twice as much carbon dioxide--the principal greenhouse gas--as the average car. This is because most of the energy consumed in our homes is produced by burning fossil fuels like coal, oil, and natural gas. This pollution is actually a hidden cost for the energy We use, over and above the dizzying $110 billion Americans spend each year on their home energy bills that's nearly $1,300 per house. Much of this energy use is unnecessary because there are a variety of proven, widely available products on the market today (heating, cooling, appliances, windows, lighting, etc.) to drastically reduce your home's energy bills, and accompanying pollution.

Generator installations FAQs
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 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.
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
