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."

"Ron Ethridge (owner) did the work. He was friendly, helpful, knowledgeable, and experienced. He was available on the phone during the project - after hours and weekends. He is very familiar with permitting and licensing and working with Pepco and the inspectors."

"when I asked for an estimate on my ceiling fan installation, Murphy responded quickly with a time estimate, and suggested a couple of deals they had available with Angie's list. I took them up on the deal that seemed the best fit for my project, and made an appointment for the work online, so easy! The techs were on time, polite and professional. excellent work on the install, including electrical boxes and remote controls."

Generator Install questions, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window.
