Estimate a preliminary whole-home cooling load in BTUs and HVAC tons using conditioned square footage, Texas climate, ceiling height, insulation, windows, sun exposure and duct conditions.
Calculate HVAC TonnageOne HVAC ton represents approximately 12,000 BTU per hour of cooling capacity. For a broader sizing estimate, compare this result with our HVAC size calculator and BTU calculator .
Enter your home characteristics to generate a preliminary cooling-load estimate.
This is a preliminary planning estimate, not a Manual J load calculation or equipment-selection recommendation. Final HVAC sizing should account for the actual building envelope, orientation, infiltration, ducts, design temperatures and equipment performance.
The calculator rounds the raw estimate to the nearest 0.5-ton reference size only to make the result easier to understand. It does not mean that a contractor should automatically install that equipment size.
