"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 has been our Electrician of chose for the past three years. I started out using Ron to service my generator after the warranty lapsed. Heâ  s provided that big company expertise with that small organization connection. Since that time Ron and his team have provided electrical services for our entire home. I feel comfortable leaving Ron in our home while weâ  re away which is a huge feat for me particularly. Iâ  m grateful for the service that Ron and his team continues to provide to our family."

"Callahan Electric has been our choice for 6 years! Last week Cody replaced a ceiling mounting box, installed a new ceiling fan and replaced a wall switch. He was not happy with the quality of the provided plastic switch cover, so he installed an upgrade that matched the others in our home! Given the current situation, we were a bit apprehensive about having a contractor in our home. Our fears were put rest when Cody arrived in a mask (early, no less!) and explained Callahan's commitment to continued meticulous adherence to science-based guidelines during these challenging times. Callahan has provided stellar electrical expertise for projects ranging from a major "from the studs out" renovation of our home to installing a new ground fault receptacle at our pond and everything in between. They are, and will continue to be, our electrical contractor of choice."

"Everything was installed correctly, but it was crooked. A little bit of effort to make it straight goes a long way. But overall, happy with the job and would hire again. They were punctual and delivered what I needed."

"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

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.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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. 

Many services include assembling the unit and securing it in the window. Confirm with your provider.
