"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

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

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

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

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

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

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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.
