About this app

HVAC Calculator Pro brings practical HVAC calculations and local job records into one focused field toolkit. Estimate quick heating and cooling loads, compare duct sizes, check airflow, convert common units, and keep every saved result tied to the assumptions that produced it.

QUICK HVAC CALCULATORS

• Estimate BTU/h and nominal tons from direct job inputs.
• Compare round and rectangular duct sizing references from CFM and target velocity.
• Calculate airflow from duct area and velocity.
• Convert temperature, capacity, airflow, pressure, length, area, and volume units.

FIELD-READY RECORDS

• Save calculations to named jobs with optional client, location, and notes.
• Reopen exact inputs, outputs, assumptions, units, and formula versions.
• Search, sort, filter, favorite, archive, duplicate, and organize job history.
• Start from built-in climate presets or create reusable custom presets with Pro.

CLEAR EXPORTS

• Export raw local data whenever you choose.
• Pro adds polished PDF reports, structured CSV data, unlimited job history, custom presets, and backup/restore.
• Pro is a one-time purchase. There are no ads and no subscription.

PRIVATE BY DESIGN

No account is required. Calculations and job records are stored on your device unless you explicitly export a file. HVAC Calculator Pro includes no advertising, analytics, crash-reporting, or cloud-sync SDKs.

IMPORTANT LIMITS

Quick load and duct outputs are informational reference values, not Manual J, Manual D, code-compliance, or equipment-selection certifications. Verify inputs and results against equipment data, manufacturer guidance, professional requirements, and local rules.
