"Great follow through, good pricing. The generator required several trips and follow-up items because it required different inspections. They did a great job at following up on these steps and the generator works perfectly. Since that time we called them for some smaller electrical jobs. They are very detailed oriented, an example would be that I gave what I thought I wanted and they gave feedback based on their experience showing a better way to do it. I welcomed this and was happy they suggested it."

It went very well.  Due to some problems with kitchen appliances not working properly due to bad circuit breakers and knowing the electrical panel is about 30 years old, I thought it was time for the  panel to be replaced and possibly upgraded. 

Matt checked the panel, determined a complete panel replacement was not needed, only replacing all circuit breakers.  Some of the installed breakers were failing.

The work was done quickly and professionally.  Matt spent time as he worked telling me what he was doing and answered my many questions.

I especially appreciated his evaluation of our electrical power needs.  Based on our electric power usage now and in the future, he said we did not need to increase the amperage of the panel. 

Since the work was done, all kitchen appliances are now working properly.

"Ted, the lead electrician with Mr. Sparky came out and took a look at our project for replacement exterior lights. He was helpful in making suggestions about the type of new lights to use and gave us a very competitive proposal. Following our acceptance of their proposal, their office called to coordinate an install date. That dayTed came by and installed our new lights and adjusted them perfectly. When we used the lights that evening we were extremely happy with our choice of Ted's firm and his recommendations as well as his workmanship. We are very pleased and intend to hire Mr. Sparky of Salisbury for future electical projects!"

Generator Install questions, answered by experts

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

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.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.
