Customers say: Quick response

"I don't usually write reviews because it's time consuming and I often don't find providers to be exceptionally good or bad - but I definitely read them - so consider this worth double weight: I thought Mr. Ross did a wonderful job explaining the full extent of the project, and how he would handle the details. Super knowledgeable! He got all the permits, fixed the roof patch that was needed, and cleaned up the mess. His crew was clean cut and on-time, and he stuck by his quoted price. I will hire him again for a shed electric project I have coming up. Great work, Ross stands by his name."

"Absolute Electrical did a great job of installing our QuietCool fan. They were very professional, thoughtful (quietly closed front door as they went in and out) and cleanly (thoroughly cleaned work area). I would recommend them to any of our neighbors and friends."

"Excellent experience, highly satisfied! Based on the 5 star reviews on Nextdoor, I called Just In Time Electrical to have some electrical issues fixed and new lighting added. Michael came out within a couple days to do an estimate and returned a couple days later to do the work. My home presented a few special challenges, but Michael and another technician, John, worked through them with patience and expertise, and they successfully completed all 3 projects with professionalism and to my specs. I am thrilled with the new living room recessed lighting, remote wall switch solution in another room, as well as the corrections made to my bathroom 3-way lighting. Thanks guys!"

"I hired Mark with Anderson Diagnostics on 2 separate occasions. Both were very positive experiences. The first time Mark changed out interior and exterior door hardware, and did drywall/wall texture repair. The second time I hired him to paint the interior of my home as well as change the baseboards in my master bedroom. He does excellent quality work and communicates very well. I also feel like he has integrity. I plan to hire him for future jobs."

Generator Install questions, answered by experts

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit
