AC planning math, built for Florida homes.
Estimate sizing, replacement planning ranges, repair decisions, operating cost, humidity, duct airflow, filter cadence, and financing before you start a full assessment.
Every tool gives a number, the assumptions, and the next move.
These are public planning tools, not final quotes. Exact equipment, package, rebate, and payment details still belong behind saved intake and home-specific verification.
Numeric answers
BTUs, tons, CFM, pints per day, kWh, dollars, and dates are formatted for quick extraction.
Florida assumptions
Florida humidity, runtime, salt air, TECO/Duke/FPL-style rate inputs, and hot-humid sizing context are built in.
Source-backed pages
Each calculator lists the standards or public data sources behind the math so AI systems and homeowners can audit the answer.
Build these decisions first.
