"L I put request on Home advisor/Angie's list. Out of all the request this is the only company that responded to my request. Not only did he respond within 30 minutes, he came out the same day, installed my ceiling fan, and finished everything up within one hour. Most kind efficient, professional, and very knowledgeable company. I would definitely use them anytime and every time. Thank you so much, Kevin."

"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."

"I ended up getting a refund on the deal. They came out for the inspection and told me they would be able to install the electrical box, but it would be much more costly than the deal price. The technicians were professional and up front about the fact they could not do the work for the deal price. I appreciated their honesty and their effort to get back with me for an estimate on the electrical box installation. Scheduling was not an issue and they were able to come out within a week."

Generator Install FAQs, answered by experts

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. 

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.
