Our purpose
Home-system information is fragmented across manufacturer manuals, government and utility programs, contractor proposals and energy guidance. CoolCompare organizes those records into consistent specifications, transparent calculations and practical decision paths.
We focus on the questions that change a decision: safety, sizing, scope, installed cost, financing, incentives, operating cost, permissions, source quality and long-term ownership records.
What independence means
CoolCompare does not use product affiliate links or retailer commissions. Advertising and contractor lead relationships do not guarantee inclusion, placement or a favourable conclusion.
We do not invent tests, customer reviews, stock, prices or verification badges. When data is incomplete, the page should say so rather than fill the gap with an unsupported claim.
Who the site is for
CoolCompare serves US homeowners, tenants, landlords and small workplaces researching portable products or permanent systems. Calculator results are planning estimates and do not replace a professional load calculation, inspection, diagnosis, permit decision or installation proposal.
Who publishes the work
CoolCompare Editorial is the collective byline responsible for research, source review, calculation checks, publication review and corrections. We do not invent named experts, credentials, tests or first-hand experience.
Each long-form guide links to its sources and publication record. Readers can report a specific factual issue through the contact route; material corrections receive a new reviewed date.
