Frequently Asked Questions
About the Generator Sizing Calculator
How accurate is the generator sizing calculator?
The calculator gives a solid planning estimate based on the details you enter, such as your home size, cooling, and the systems you want to keep running. It is a great starting point, but the final size is always confirmed with a free on site load assessment by a licensed Spectrum Electric technician, since every home draws power a little differently.
Do I still need an on site visit after using the calculator?
Yes. The calculator points you to the right range so you know what to expect, but we confirm the exact unit with a free on site assessment before anything is ordered. That visit accounts for your panel, fuel source, and how your home actually uses power, so the generator is sized to real conditions and not a rough guess.
