Summary
Orange County's noise ordinance treats a running heat pump or air conditioning condenser as "intermittent sound," the code's term for noise lasting longer than one second but under fifteen minutes. That classification controls how the Environmental Protection Division measures a neighbor's HVAC complaint: instead of a single snapshot reading, the county averages a minimum five-minute Leq inside a sixty-minute measurement window before deciding whether the unit exceeds the applicable decibel limit.
(18)Intermittent sound shall mean a sound of greater than one (1) second duration and less than fifteen (15) minutes. Examples of sources of intermittent sound are air compressors, heating and air conditioning units and PA speakers. ... Sec. 15-183(a)(6): Intermittent sounds shall be measured within a sixty-minute period. A minimum five (5) minute Leq of the sound shall be required to evaluate if a violation exists.

Full Breakdown
Under the county's Table 1 sound-level limits (§ 15-182), a residential-area HVAC condenser is judged against a time-averaged (Leq) ceiling of 60 dBA between 7:00 a.m. and 10:00 p.m. and 55 dBA overnight, or 55 dBA at any time if the receiving property sits in a designated noise-sensitive zone such as a school or hospital. Because a compressor cycling on and off qualifies as "intermittent sound" under § 15-180(b)(18), the Environmental Protection Division doesn't rely on a single quick reading: § 15-183(a)(6) requires the sound to be measured within a sixty-minute window, using at least a five-minute Leq average, before a violation is confirmed. Investigators can also use the county's alternative "plainly audible" test: a residential-area sound clearly heard 100 feet away in daytime, or 50 feet away overnight, supports a citation without a meter reading at all (§ 15-183(b), Table 2).
Enforcement runs through the environmental protection officer under § 15-179(d), who can issue a letter of warning, notice of violation, or civil citation once a homeowner's noise complaint is substantiated. Under § 15-187, a first civil citation carries a $200 fine, a second carries $400, and a third or later violation of the same provision requires a mandatory court appearance and can draw up to $500 plus the county's enforcement costs, including attorneys' fees. A person who fails to correct the noise, or whose HVAC noise resumes within 180 days of an abatement, can be found guilty of a civil infraction with a penalty up to $500.
Violations & Fines
An HVAC unit measured above the Table 1 limit, or plainly audible past the Table 2 distance, draws a civil citation from the environmental protection officer: $200 for a first offense, $400 for a second, and a mandatory court appearance plus up to $500 for a third or later violation of the same rule. Noise that recurs within 180 days of correction can also be charged as a separate civil infraction.
