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. Some retailer links do earn us a commission (as an Amazon Associate we earn from qualifying purchases), at no extra cost to you and with no effect on what we recommend or how units rank. See our affiliate disclosure for the details.

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.
