Summary
Running machinery, a pump, fan or air-conditioning unit loud enough to exceed the applicable noise level limit is unlawful anywhere in the City of Ventura under San Buenaventura Municipal Code Section 10.650.150(C), which covers any nature of mechanical device, not just construction or garden equipment.
C. Machinery, Equipment, Fans and Air-Conditioning. No person shall operate any machinery, equipment, pump, fan, air-conditioning apparatus or tool of any nature or similar mechanical device so as to create any noise which exceeds the noise level limits of this article.

Full Breakdown
650. m. 130: a residential Zone II property has a 50 dB daytime and 45 dB nighttime exterior limit, while a commercial Zone III property tolerates 60 dB daytime and 55 dB nighttime. Because HVAC noise is typically continuous rather than a brief spike, the code's timing rule is the operative trigger: the unit violates the ordinance once it pushes the receiving property's noise level over the zone limit for more than 30 minutes in any 60-minute period. A homeowner or business whose new heat pump or air-conditioning condenser draws a neighbor's complaint can be required to add mechanical screening, relocate the unit or install a quieter model to bring the installation back under the zone limit.
Violations & Fines
A Section 10.650.150(C) violation is enforced through the general noise penalty in Section 10.650.180(A), which applies the citation schedule in Sections 1.150.010 through 1.150.070, and the city can additionally pursue an injunction under Section 10.650.180(B) against equipment that continues to disturb a neighborhood after a citation.
