"The salesperson that came to look at the job/s was extremely professional. He helped me fix and overhead light and changed all of my kitchen recessed lights during our meeting. The price he quoted was $700.00 less then Mr. Electric. The work was completed the next day. They electricians were great. The only reason I didn't give an "A" on quality is because when they replaced a GFI with a new bright white switch, they left the old dingy ivory switch plate on it. It is a totally eye sore. i would have paid the extra for a new white switch plate. I didn't notice it until they left. I would have certainly said something. Great job over all. I would use again!"

"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."

"My house is not young. With every little hiccup that cropped up, Dave Gill maintained safe practice while working with me to see I got what I needed, and went well above and beyond, when it came to being considerate, even doing little 'extras' I have never received from an electrician before!"

"An initial estimate/consultation appointment was set with James (owner).  He arrived on time.  We did a room by room of all the things I wanted done in the house.  We agreed that I would purchase the light fixtures, bulbs and GFI receptacles ahead of time.  He arrived on time for the installation and, all work was completed as discussed and explained to me afterward.  He gave me a fair price for and did a great job. I appreciate his honesty and would definitely hire him again in the future."

"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 questions, answered by experts

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.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.
