"The contractor sent to my house was NOT a licensed electrician. I was told a free quote was 39.99, that turned to 59.99 when I got the estimate and it was waaaaaay over priced and then wanted me to pay a fee to get a warranty for their work! I would have expected a warranty on his work should have been given to me! I needed the job done right away, he was pleasant and courteous but never again with this company."

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...."

Constellation Home provides high-quality, personal service that you've depended on for decades. Constellation Home is Maryland's go-to home service provider for EV Charger installation, heating and cooling, water heater, plumbing. electrical and home improvement needs. Our team will continue to arrive on time, in uniform and ready to get the job done right the first time. All backed by our 100% satisfaction guarantee. We Know More, We Do More.

"I've been a Constellation Home customer for years, and I'd like to share my honest experience. If you're not in a hurry and don't mind waiting for service, this company might be fine. But if you need timely repairs, I strongly advise you to think twice before purchasing their service plan. My air conditioner broke on June 20. A technician came out the next day, June 21, and confirmed the compressor needed replacement. The part was ordered the same day, and I was told it would arrive by June 25. Since then, I've called daily. Each time, the receptionist tells me, "It's coming today." I've repeatedly asked to speak with a parts manager and was promised a callback--yet I only received one call, on June 27. As of today, July 2, the issue is still unresolved. Meanwhile, my elderly parents have been living in extreme heat during a heatwave. Please think carefully before signing up with this company. If you expect timely service, this may not be the right choice. I will be sharing this ex"

Many people believe that their car is the largest single source of air pollution for which they are personally responsible.

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 Install questions, answered by experts

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

The cost to install a whole-house generator averages at $5,200, but costs can range from $1,500 to $8,900, depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don’t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.

In many cases, you’ll need a permit or basic inspection to install one of these large generators. Since they include significant alterations to your home electrical system and many produce exhaust fumes, local governments often require jumping through a few hoops for general safety purposes. Your installer may be able to help you with these permits.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.
