"The crew very polite and informative. The whole house generator installed in one day and my place was left clean. The installation project was done in a cosmetic pleasing manner and no ugly pipes or wires are visible. I was given a detailed cost of the project and kept informed at all times. It was not the lowest bid but the work was excellent and I am very happy with the finished project. The office staff are very helpful and their excellent service and detailed bid is why I chose to go with LT Generator."

"Hired Ken and his team for a complete knob and tube rewire of our historic 1911 home as well as installation of LED trim kits, a ceiling fan and some light fixtures. The cost v scope and quality of the work was the best value I've seen as a new homeowner. All members of the company, from the on-site techs to Ken were friendly, hard-working, responsive and communicated well. All tasks, estimates and invoicing were clear, concise, and open to questions and discussion. It was a rewarding and satisfying experience which one does not usually expect from contractor projects. I highly recommend including Johnson Electric in your bidding process, you will not be disappointed."

"It went well. 2 fellows showed up and went to work mapping circuits and their beginnings. Then they installed AFCI/GFI"s at beginning of each circuit."

"Albrik Electric Co was contracted out as a 3rd party to complete an installation for a business client. The former electrical contractor was let go and Albrik Electric Co stepped in to resume the work. Between the ease of communication, the quality of work, flexibility of work time, and fair pricing, I highly recommend using Albrik Electric Co. We will consider using this company again for future projects."

Generator Install questions, answered by experts

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.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

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.
