FAQ
Common questions
Is CoolVerdict free to use?
Yes — the BTU calculator, comparison tools, buying guides, and HVAC-contractor directory are all free, with no sign-up required.
Is CoolVerdict independent?
Yes. Recommendations are based on specs and data, not paid placement — there are no sponsored rankings, and any future affiliate links will be clearly labeled and will not influence rankings.
Where does CoolVerdict’s data come from?
Product specs come from manufacturer documentation and independent testing, shown with each unit’s true efficiency metric (CEER, EER, SEER, or SEER2). Contractor listings are compiled from public information. See How we rate.
How accurate are the running-cost estimates?
They are estimates based on each unit’s efficiency, typical usage of about 8 hours a day, and average residential electricity rates — your actual cost varies with your utility rate and habits. The calculator personalizes it to your room and state.
