Summary
Unincorporated York County exempts ordinary HVAC unit sound from its residential noise-decibel cap, so a working air conditioner or heat pump condenser is not, by itself, a code violation. The exemption sits inside § 56.016(B)(18), the section that otherwise limits noise in residential areas to 60 decibels at the property line.
In any residentially zoned area or within 300 feet of any residentially occupied structure in any zone, the noise resulting from any activity, whether open or enclosed, shall not exceed 60 decibels at any point on or beyond the lot line. The following shall be exceptions to this division (B)(18): ... (i) Sound which was generated by an HVAC unit;

Full Breakdown
016(B)(18) of the York County Code caps noise in any residentially zoned area, or within 300 feet of a residentially occupied structure in any zone, at 60 decibels measured at or beyond the lot line. ' That means a condenser, compressor, or air handler running as designed is not measured against the 60-decibel residential ceiling the way a stereo, generator, or industrial process would be. 016(A), which still prohibits any noise that 'annoys, disturbs, injures or endangers the comfort, repose, health, peace or safety of others'; a defective, rattling, or unusually loud HVAC unit could still support a complaint under that broader standard even though it escapes the numeric decibel test. 017(A) before citing anyone.
Violations & Fines
Because HVAC sound is carved out of the decibel standard, a functioning unit cannot be cited for exceeding 60 decibels. A malfunctioning or abnormally loud unit can still be cited as a nuisance under § 56.016(A); a first confirmed complaint gets the owner a chance to fix it before any penalty, but a repeat within 90 days is a misdemeanor carrying up to a $500 fine, up to 30 days in jail, or both, under § 56.999.
