MightyBee Electric is a family owned, GREEN local company with 34 years in the field. We do not charge a trip fee for Angie's List members within the direct Denver metro area ( except Boulder, Longmont, Castle Pines, Castlerock and Parker which will be charged a $39 trip fee) and give free estimates up front of the work always. We never assume authorization and customers can pay by cash, check or credit card at the time of repair. Formerly owned MD ELECTRIC.

"I am giving a C-rating, when an F is probably more appropriate, due to not great customer service and the fact that I ended up spending much more money than was necessary because of the rude woman who schedules appointments and answers the phone. They get a score of C because ultimately what I asked the electricians to do, they did. I am writing this to make sure anyone who considers this company is well aware of the issues. The electricians were good, but there were problems with the job that I have outlined below. The job: I had two ceiling fans I wanted replaced. I bought two new ones and the electricians did install them and haul out the old fans. The job was completed satisfactorily. History. About two or three weeks ago I started detecting a burning smell coming from one fan when the light was on. I searched Angie’s List for an electrician and chose MightyBee. The woman who answers the phone is rude. I told her the problem and she couldn’t get me off the phone fast enough. She said it was more expensive to find replacement parts than to just buy a new fan. It was clear she didn’t want the job. I am moving, I’m in a time crunch, and I finally decided it would be easier to just buy new fans than to try to find someone who could fix the one with the burning smell. I have a sort of master suite setup with two fans, so they have to match. Replacing just one fan was not an option. The fans I had are no longer produced. I did not intend to call MightyBee again, but I did accidentally. Same rude woman who answered the phone the first time I called. I have no idea what is up with this person. It’s like calling to schedule an appointment just ruins her day. Anyway, I went ahead and scheduled. Same reason as before. Time crunch. MightyBee has this A rating and I figured: how bad can it be? Day of appointment. This is a REALLY, really low-tech company. No appointment reminders, no text messages, no emails, no call ahead to let you know they’re coming. I got an appointment window and that was it. Next thing I know, the guys are at my door. It’s snowy, dirty and mucky outside from a recent heavy snowstorm. They came in, shoes CAKED with ice and dirt. They walked onto my clean hardwood floors without even enquiring if it was okay first. I asked if they had shoe covers. No. I have white carpet upstairs where the fans are, and the carpet had JUST been cleaned. They did remove their shoes, which is fine, but it was inconvenient for them since they had to keep going outside to the truck. Why would any company who does work in people’s homes not provide shoe covers? Unbelievable. As I said, this company is really low tech. While working on the ceiling fans, they spread the parts out on my clean white carpet, including the old dusty fans. No drop cloth. This really bugged me, but the carpet survived, so all’s well that ends well, I guess. Turns out, the burning smell wasn’t the fan at all. Wasn’t electrical. It was the transformer for the remote control for the fan I’d installed years ago, and the transformer had malfunctioned or burned out. This is an add-on part, not part of the fan. If they had come out in the first place to take a look, all they had to do was remove the remote-control transformer and install a new one. That was the only problem with the fan. Basically, the rude woman on the phone cost me $800. The cost of 2 new fans and the installation. If the two electricians had not been nice and done a good job installing the fans, I would have given the company an F because of the rude woman who answers the phone and the fact that she doesn’t give two hoots about helping you with your problem. The electricians are fine. Very nice. Good at what they do. Really accommodating guys. For them, the company gets a C."

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
