"I first used Eddie to deal with a problem with a breaker and was advised that the panel itself should be replaced due to the age of the panel. Work was performed in a timely manner, and we now have much cleaner power with less chance of a breaker randomly tripping/failing... Am very satisfied with the work and response. Highly recommended!

Generator Install questions, answered by experts

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

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.

As long as your generator is used as recommended by the manufacturer, it’s safe to use for auxiliary power. Make sure that fuel powered generators are used outdoors and that the fumes dissipate away from your home. A professional generator installer will ensure your generator’s placement and set-up meets safety standards when installing or repairing your back-up power source.
