BaseCalc HVAC Calculator is an HVAC calculator for field math, worksheets, materials, and saved calculation history. Run BTU, CFM, duct sizing, airflow, psychrometrics, manufacturer-data refrigerant checks, planning load, hydronics, and other HVAC calculator arithmetic on site, then save the result for the job. 18 CALCULATORS FOR DAILY FIELD WORK • BTU ↔ Tons — convert between BTU/hr and refrigeration tons. • CFM from BTU — airflow from load and temperature rise/drop. • BTU from CFM — load from airflow and temperature difference. • Duct Sizing — round and rectangular duct from CFM and velocity. • Air Velocity — velocity from CFM and cross-sectional area. • Psychrometrics — total, sensible, and latent BTU/hr estimates at standard atmospheric pressure. • Refrigerant Lines — check entered manufacturer line data against an entered equivalent-length limit. • Superheat / Subcooling — record the exact target supplied by the equipment manufacturer. • Room Load — preliminary area-factor planning math using your supplied factor; not Manual J. • Heat Pump Balance — interpolate a bracketed balance point from entered manufacturer capacity data. • Hydronics — BTU, GPM, and ΔT relationships. • Mixed Air — mixed-air temperature from outdoor and return air. • Air Changes — ACH from CFM and room volume. • Evaporative Cooling — supply temperature and sensible air-side estimate. • Filter Velocity — filter face velocity; use manufacturer data for pressure drop. • O₂ Excess Air — theoretical dry-flue-gas dilution estimate from measured O₂; not a safety result. • Refrigerant Weight — additional charge from an entered manufacturer allowance and rate. • Outdoor Airflow — breathing-zone airflow arithmetic from user-supplied per-person and per-area rates. EVERY RESULT IS EXPLAINED • Explicit input validation, assumptions, and calculation boundaries. • Final arithmetic and a calculation breakdown where the supplied data supports one. • Saved local history so you keep a job-site record. BaseCalc HVAC is a professional reference tool. Always verify against current industry standards, manufacturer data, and local codes. The authority having jurisdiction has the final say.
