"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."

"Very courteous folks to deal with. They replaced the battery in my generator, so I really can't comment on the quality of their electrical work. I was a little surprised by the amount of the bill ($255.00). but that is the hourly rate for electricians these days, I guess."

Generator Install questions, answered by experts

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.

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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.
