AC Tonnage Calculator
AC Tonnage Calculator — quick estimate
Estimate the cooling load (in TR) your space needs from a quick heat-load model. Adjust the inputs for an instant figure — then get a proper engineered HVAC design from our team.
Your space
Quick estimate from a sensible+latent heat-load model. Server rooms assume IT heat load; a detailed survey (glazing, orientation, equipment) is needed for the final design.
Cooling load is the estimated demand; recommended capacity is the nearest practical installed selection.

Thanks! Our HVAC team will send your tailored cooling design within one business day.
Indicative pre-sales estimate only — not a binding design. Final tonnage and unit selection depend on glazing, orientation, insulation, ventilation, internal equipment heat and operating hours, and must be confirmed by a detailed heat-load survey.
Need an exact BOQ, rate analysis or measurement sheet?
This is a quick engineering estimate. For tendering, billing or audit, our QS & estimation team prepares an item-wise BOQ, rate analysis and a verified measurement sheet to IS / CPWD norms — backed by 15+ years and ISO 9001:2015 quality processes.
