Summary
Rochester's excessive-noise ordinance flatly exempts air conditioners from its property-line noise thresholds, so a running AC unit cannot be cited under the general curfew the way other sound sources can, per Municipal Code § 75-4B(6); other noise-sensitive protections in the chapter still apply.
The provisions of this section shall not apply to noise emanating from the following: ... (6) Air conditioners.

Full Breakdown
, is prima facie a violation. is not, by itself, a basis for an excessive-noise citation under § 75-4. That does not make HVAC equipment untouchable everywhere in the code: § 75-11 separately bars noise, from any source, that unreasonably interferes with a school, church, court, hospital, nursing home or home for the aged while in use, and a nuisance claim under other chapters of the Municipal Code could still reach an AC unit that is genuinely disruptive. threshold specifically carves air conditioners out of it, which distinguishes HVAC noise from most other mechanical sources regulated elsewhere in Chapter 75, such as construction equipment under § 75-10 and sound reproduction devices under § 75-12.
Violations & Fines
Because § 75-4B(6) exempts air conditioners outright, the City cannot cite a unit under the general excessive-noise penalties in § 13A-11 for simply running. A complaint alleging AC noise near a protected use like a hospital or school under § 75-11, or a separate property-nuisance claim, would instead carry whatever penalty applies to that other section.
