I built HVAC Tools Hub to bring practical HVAC calculators and technical references together in one clear, accessible workspace. Many online tools provide a number without explaining the formula, units, assumptions, or limitations, so this project focuses on making every result easier to understand and apply. I would appreciate feedback on missing tools, unclear explanations, or calculations that could be improved.
