Who reads this site
tonnagecalc.com is a set of free Florida HVAC planning tools: a tonnage calculator with a house-specific load option, a SEER2 cost calculator, a filter size finder, a dehumidifier pint planner, and plain-English pages on short cycling, AC freezing, humid houses, hurricane prep, and first-cold-night heat smells. Readers are Florida homeowners trying to understand their system and techs who want quick sizing math.
23 pages are live, and new Florida pages are added most weeks.

Source: the site's own first-party page counter (no cookies sold, no third-party tracking). It counts browsers with JavaScript on, so it can miss some real visitors, and it includes a few of our own check visits. This is a new, small site. We price for that and send you the real numbers every month.

How we set these: at about 100 page views a month, paying by the thousand views would cost only a few dollars a month. These are flat rates for an exclusive spot in front of a small, Florida-only HVAC audience, locked for 12 months while the site grows. Month to month, cancel any time. Billing starts when the ad goes live.
