"I hired K & K to install a range hood. There was no electrical there previously so they had to run electric. I also had them install a new light fixture and remove an exhaust fan. K & K did excellent work and even repaired an electrical box that another contractor had installed. I was given a great estimate and was charged the estimate price. Would definitely use again and recommend."

"Russell was prompt, very polite and helpful. He explained everything and pointed out where my old rowhouse differs from newer codes. (Grandfathered until I want to sell.) There was an upsell on an annual plan, but it will save some 15% on some planned upgrades, so I went with it. Dawn, office support, also was friendly and pleasant to work with. She gave me a follow-up call next morning after my multi-company query through Angie's. My inquiry detailed list of three small repairs did not get other takers, so no real cost comparison, but I feel the price was fair-- $500 for about 2 hours, including the plan and dispatch fee."

"They checked my generator and said nothing was wrong, that the problem was probably with the electric companies transformer. My problem still exist. The electric company sent people out to check the current coming to my house and said everything is okay. They are going to install a monitor to check what is going on when there is an outage. So as of now my generator does not come on."

Customers say: Quick response

"Anthony and his team do expert electrical work of all kinds. We are a 145 year old non-profit organization with buildings and grounds, and have contracted with Technician Engineers Group (TEG) on two large projects (and several small ones) over the last 15 years. One project rewired a large 125 year old building listed on the National Register of Historic Places, and one installed an extensive outdoor lighting system. In these two unusual situations TEG worked closely with us to find innovative solutions to our unique needs. We are very pleased with the results, enjoyed their can-do approach, and highly recommend this company for any electrical challenge. We found TEG reliable, honest, on time, and all the work was completed ahead of schedule."

Generator Install questions, answered by experts

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

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 cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.
