Use practical worksheets and estimates before you call, compare proposals after contractors visit, and keep a simple maintenance schedule afterward.
Start My HVAC Project — one private workspace connects these three tools.
Put up to three proposals in one view. Compare installed price, equipment, efficiency, warranties, permits, sizing, and startup details in one worksheet.
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 so you can see how each estimate is calculated.
The worksheet organizes proposal facts. It does not endorse a contractor, sell your information, or select a winner.
