How long the equipment lasts: ENERGY STAR says to consider replacing a heat pump or air conditioner once it is more than 10 years old. InterNACHI's Florida chart lists a central air conditioner at 5 to 12 years and calls its figures guidelines, not guarantees. In Zephyrhills, 7,732 homes (77.8%) were built before 2010, so an original system still running is at least 17 years old, past both benchmarks.

Another 1,570 (15.8%) were built from 2010 to 2019, where an original system is 7 to 16 years old and crosses the 10-year line partway through that decade. The 635 homes built since 2020 (6.4%) are under 7 years old. The Census does not record replacements, so these are ages of original equipment, not a count of failing systems.

A licensed contractor can apply for the permit for you; if a homeowner applies instead, Florida law requires the owner to sign the application personally (F.S. 489.103(7)). Call the department for the current fee and steps. Checked 2026-09-30.
