Use practical worksheets and estimates before you call, compare proposals after contractors visit, and keep a simple maintenance schedule afterward.
Put up to three proposals in one view. Compare installed price, equipment, efficiency, warranties, permits, sizing, and startup details without an opaque score.
Compare two central-cooling efficiency scenarios using your system capacity, estimated cooling hours, electric rate, and seasonal efficiency ratings.
Review homeowner and professional maintenance tasks, calculate your next filter-inspection date, and download a standard calendar reminder.
The calculators do not submit a form to our server. The quote worksheet saves only in your current browser so you can return to it, and includes a clear button.
The cooling calculator displays the formula, inputs, and limitations instead of presenting a hidden “smart” estimate.
The worksheet organizes proposal facts. It does not endorse a contractor, sell your information, or select a winner.
