HomeCalc Pro
Free calculators for HVAC sizing, materials and mortgages
About HomeCalc Pro
HomeCalc Pro is a library of free online calculators for homeowners, DIY renovators and contractors planning home projects. Its tools cover HVAC load and BTU sizing, duct and fan sizing, heating and cooling cost estimates, material quantities for driveways and insulation, and 30-year mortgage analysis.
The site says its HVAC tools follow ACCA Manual J methodology and that material estimates include manufacturer waste factors. Calculations run in the browser, and the site states that project data is not sent to its servers, with no account or sign-up required. Results can be exported as PDF reports.
Unlike general-purpose calculator sites, HomeCalc Pro is focused on construction, HVAC and renovation, so it aims to help users avoid oversized equipment and overbought materials before they commit to a project.
