"This is the first time I used Mr. Sparky, and they will definitely be my new go to electricians! I love that they are a small locally owned business! I called about a small non-urgent project, and they were able to come the same day, despite being backed up due to many local flooding issues. Kasey was extremely friendly and helpful on the phone and communication was excellent from start to finish. James showed up on time and was very sweet, yet professional, and my cats even loved him :) He was respectful of me and my property, and took care of my issue in no time. The price was very reasonable! I will definitely call them again, and would highly recommend!"

"Elliott does great work for a great price. He installed a new 100 amp breaker box and updated some of the house wiring to accommodate the new service. He also wired the newly renovated basement with all the wiring and installed all the outlets, switches and drop ceiling LED lights that have dimmer capability. He is meticulous in what he does."

"Politely said, Sparky is the boss.  
We needed electricity and HDMI ran from a cabinet in our great room up above our fireplace so we could mount a TV.  Also needed cable and electricity ran to a wall in our master bedroom so we could mount our TV on the wall. 
Sparky showed up on a Friday afternoon, five minutes early.  Assessed the situation, and before he left, said he would look into how much parts/etc would cost, and he would call me with a bid.  Sunday night I received a text from him with a bid, we set up a time for him to come for the install on 8/22 at 9am.  
Sparky showed up at 8:59, and got to work.  I came home from lunch to outlets installed where I had asked, cable ran, everything was great.  He could not find the specific outlet cover for AC / Cable, but it will not be visible once the TV is mounted, so it is not of real concern.  
I was a little uncomfortable mounting the brackets for our TV on the walls, as the studs were located in odd places - and I didn't trust myself to mount a $1,000 60" plasma anywhere that wasn't on a small stand.  ha!  
I asked if he would mind installing the mounts if I kicked him some extra $$, and he gladly obliged to stay longer than he had originally intended.  He even went so far as to use his own screws/mounting bolts that were FAR superior to the ones that were provided in the kit.
Couldn't be happier.  Should we plan on doing any other electrical work / lighting in the future, Sparky will be our first call.

"There is no air conditioning on the first floor of the non-profit house for which I am Property Director.  With the donation of and installation of a window AC unit, it was suggested that a ceiling fan in the living room (where the AC unit was installed) would help circulate the cool air.  I had worked w/Horizon Electric previously for electrical repairs, but not for an installation requiring new wiring, etc.  The owner, Lee, met me at the house within a few days and almost immediately found a way to wire in a new ceiling fan in the living room.  With further discussion we decided a ceiling fan w/lights would also be worthwhile in the dining area.  In that case he had to extend wiring to this adjacent room and, again, came up with a solution.   He quoted me a price for the installation of the living room fan only and another for the installation of both fans.  
With Board of Directors approval I was able to get back to him within the week and the following week both fans were installed. Even though Lee had told me that his workload was out 2-3 weeks, he understood the importance of getting these fans installed 
and that was done in record time.  The House Manager reported to me that the workman finished the installation of the fans we provided in one day, as promised, and, even with the house residents present (including young children), left nothing lying about that could be hazardous to anyone, was efficient and cleaned up the work area thoroughly after he was done.
We were billed the amount quoted.
I would definitely use this company again and highly recommend it.

"Excellent work! Project involved running 100A service from house to detached garage, running power to equipment, and installing outlets. Happy with the price and was impressed with the work, so I decided to expand the scope - am having him come back to put in some more circuits. I have hired a number of contractors over the years, including at work for some involved projects. Marty is up there with the best: great communication, personable, completed the work sooner than I expected, and his experience shows - around 15 years, including industrial and commercial experience. He recently started his own business."

Generator Install questions, answered by experts

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

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.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.
