Our Mission
HVACSizingPro exists to give homeowners the information they need before calling a contractor. HVAC is one of the largest home expenses most people ever face — but most homeowners go into quotes completely blind. We fix that.
Every calculator on this site is built around real industry formulas: ACCA Manual J load calculations for sizing, DOE-standard SEER2 efficiency math for savings, and real regional cost data for replacement estimates. Our tools give you accurate estimates in 30 seconds so you can negotiate from a position of knowledge.
What We Offer
Five free calculators covering the questions homeowners ask most often:
- HVAC Sizing Calculator — BTU load and tonnage by room and climate
- Replacement Cost Estimator — real regional price ranges before you call anyone
- Heat Pump vs. Furnace Calculator — 15-year TCO comparison for your utility rates
- Mini-Split Sizing Calculator — zone-by-zone ductless sizing for single and multi-zone systems
- SEER2 Energy Savings Calculator — payback period and ROI on an efficiency upgrade
