If a city's size or running cost looks wrong, that is worth hearing: the point of the site is a number you can check a quote against. The most useful reports say what a contractor's Manual J gave for your house, and its square footage, or point to a better weather station for your town.

What we cannot do

We cannot run a load calculation for your house, review a specific quote or recommend an installer. See the terms of use. Your city's page is a good starting point to take to a contractor.
