"New to the area, I needed a hookup for an emergency generator and EV charger. Cole came to my home, took the time to discuss different options and answer questions, and provided a detailed, written estimate, all the same day as my initial inquiry. The project was completed within a few days. His price was very competitive and his work meticulous. A true professional."

"Wow, they just left and I am so beyond impressed with everything, from start to finish. Adam helped with our estimate and was a pleasure to work with. He came next day for our estimate and from there, went above and beyond to answer every single question and concern of mine, he was fair in his pricing, very timely in his responses and even remembered the layout of our home when I called a month later. They were even able to schedule the job next day due to the inclement weather. Jim and Matt arrived early and were so courteous and pleasant to work with (they were even extremely considerate of my infant's nap schedule). We had them install two new outlets for ac's and electronics and they had to snake the wires in impossible places. Jim listened to every single one of my concerns and came up with excellent solutions and they left everything in better condition than they found it. When I asked if there was another way to get the job done, he listened and offered to change his plan. It was so nice having a contractor actually listen to you and work with you. I will definitely be hiring them again - I am so glad I finally found an electrician that is respectful of an older home. Thank you Adam, Jim & Matt! You guys rock!"

"John is a very professional electrician and is very knowledgeable about what he does. Him and his crew have many years of experience doing this kind of work and it really shows. I just had them install a new car charger for me and I couldn’t be any happier with the results!"

"I used Call Me Electric because they were highly reviewed on angie's list, and after using them their reviews are right on. they are amazing at what they do, and very prompt and professional. i had a light post installed outside, a light fixture installed at my front door and back door, electrical outlets repaired outside, light fixture installed in my office, and had my basement lights replaced with led lights. All the work was done just the way we wanted it. I want to think Ralph, John, Andrew, and Nick for being very professional and doing a great job. i highly recommend them for all your electric work and i will be using them in the future. thanks again."

"Dependable Renovations LLC. was a pleasure to deal with. Steve and his staff are knowledgeable, courteous, honest and professional. All work was completed, as discussed and in a timely fashion. What I truly appreciate is the concern for the cleanliness of their work and the respect of their surroundings. That's something you can't teach. I would highly recommend Dependable Renovations for any work consideration."

"Anthony came to perform a cleaning and inspection of our old furnace. Immediately after he was done I felt a difference in air flow and fresher smelling air through the vents. He checked the furnace for any issues and didn't try to push any extra services. I did ask a bunch of questions and he answered them patiently! I look forward to calling him when its time to install Central Air and replace our furnace. Thank you!"

Generator Install FAQs, answered by experts

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

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.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.
