"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."

"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."

"It went great! Pete and Dave were fast, friendly, and professional. They did a great job installing the ceiling fans in my rooms. They made sure to protect my belongings so that nothing was damaged during the installation. And the quote they gave me was spot on. Their prices are affordable. For what they charged to install 3 fans, another company wanted to charge me just to install 1 fan. I absolutely would highly recommend contacting Supreme. I will be definitely contact them for additional work I need to have done!"

"Although the installation took more than a day, the communication of the installer was excellent. The job required new pipes and an expansion tank, so it was more than installing one piece of equipment. All questions were answered (there were many) and the workmanship met my high standards."

"I highly recommend CAP Electrical for all of your electrical needs! Not only do they do an outstanding job, but they are extremely friendly, customer service oriented, and honest. The day that Rod (President) came out to give me an estimate, I thought that I had a short in one of my kitchen light fixtures. Rod quickly pointed out that I was not using the right type of bulb in the fixture (non-dimmable bulb on a dimmable light). That display of honesty led to me hiring Rod and his guys for the rest of the work I needed done, and I'm very glad I did. They ended up installing recessed lights in my basement, a receptacle on my front porch, repairing switches in my main breaker panel, and fixed existing receptacles throughout my house. The electricians Rod sent were very personable and courteous. They worked very efficiently, and ensured that my satisfaction was their number one priority. As the electricians worked they informed me that some of the work that they did was not as involved as originally anticipated, which ultimately led to me saving money. Another display of honesty and customer service at its finest. In addition, CAP was very flexible when it came to scheduling a day to come out. If you're looking for a company that prioritizes customer service and is extremely honest then look no further than CAP electrical. They are very good people who work hard and do the right thing! I'm very pleased with the work that they did and I know you will be too."

Generator Install FAQs, answered by experts

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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.

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.

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.
