The comparison unit
A product is not a project. We separate equipment identity, installation labor, materials, permits, electrical or fuel work, commissioning, warranty and exclusions.
Cost and ownership
Planning ranges are broad orientations. They are not quotes, financing offers, tax advice or incentive reservations. Where users compare scenarios, we keep assumptions visible and encourage a five- and ten-year view.
Commercial independence
Sponsored placement, affiliate links and contractor relationships must not rewrite source-backed specifications or the core comparison method. Commercial links are disclosed and never replace a full scope review.
