"We had Henderson Electric hook up the electrical for our new hot tub. They installed the proper breakers, ran conduit/wiring through the attic, to the outside wall, underground to a post, then mounted a switch panel and completed wiring to the hot tub. Can't say enough good things about our experience. Excellent quality of work overall. Very clean and complete professional work. Also very good communication and follow up, which, unfortunately, is not all that common these days. Classic example of doing it right or don't do it, which we really appreciated. We also appreciated the knowledge and expertise as we knew what we wanted done, but not necessarily the best way to accomplish what we needed. They helped us explore and weigh out several options for different ways to do the job, and explained pros and cons of each option. Gave us an estimate the next day and got us on the schedule right away. We had contacted other contractors/electricians and got a few other estimates, some more expensive, some less, but none of them gave us the level of personal service and professionalism like Henderson's. Would absolutely recommend Henderson's to anyone looking to get any home electrical work done."

"Near impossible to get ahold of them, I understand being business, but then there is blatant ignoring. Even after planning another job. I cant access my Internet cable as its now stuck under a outside wire tube. Needing to call my Internet provider to get it moved."

Generator Install FAQs, answered by experts

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.

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.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

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.
