"Outstanding work, outstanding people. Excellent workmanship and a pleasure to do business with; very professional. Installed recessed lighting in M/BedRm and FamRr. Replaced 2 indoor ceiling fixtures, added an outdoor outlet to our front porch, replaced outdoor porch lights and pole light and added heat lamp to the M/Bathroom. All done without any drywall damage, no holes to repair. One estimate I got told me they would have to put 4 or 5 holes in my Family Room ceiling because the attic only extended halfway above the Family Room. Spoke to Keith (owner) @ All In Electric and he just laughed and said his guys will not put any holes in my ceiling, they know how to fish wires!! Best of all his pricing was competitive with the 3 other estimates I got. Great communication throughout the project from proposal to finish!!! Highly recommend AIE."

Many people believe that their car is the largest single source of air pollution for which they are personally responsible. But in fact, the average home causes the emission of more than twice as much carbon dioxide--the principal greenhouse gas--as the average car. This is because most of the energy consumed in our homes is produced by burning fossil fuels like coal, oil, and natural gas. This pollution is actually a hidden cost for the energy We use, over and above the dizzying $110 billion Americans spend each year on their home energy bills that's nearly $1,300 per house.

Generator Install questions, answered by experts

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.

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.

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.

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

The typical cost of a home generator is around $5,000, but prices range from $400 up to $13,000, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between $500 and $2,000 or a partial-home generator for between $2,000 and $6,500. Whole-home generators usually total between $5,000 and $13,000, with some models climbing as high as $18,000.
