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 Spring Hill, 44,492 homes (90.8%) were built before 2010, so an original system still running is at least 17 years old, past both benchmarks.
Another 3,598 (7.3%) 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 906 homes built since 2020 (1.8%) are under 7 years old. The Census does not record replacements, so these are ages of original equipment, not a count of failing systems.

Do I need a permit to replace my AC in Spring Hill?
Yes. The Florida Building Code (section 105.1) requires a permit to replace a mechanical system, and a central air conditioner is one. In Spring Hill, the Hernando County Building Division handles it.
Its residential permit guide says anyone who wants to "replace any ... mechanical ... system" must first apply for a permit. The only air conditioning items on its no-permit list are a window unit with an existing outlet and repair of existing equipment, so a replacement is not exempt. 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.
