Summary
Murfreesboro doesn't single out air conditioners or heat pumps: continuous HVAC noise is governed by the same 'steady sound' exterior dBA limits in § 21-106(B) that apply to any fixed source, checked at the neighboring property line.
Notwithstanding the provisions of this subsection, where a particular activity, sound source, or device is subject to decibel level limits and requirements specifically prescribed for such activity, source, or device elsewhere in this Article, the decibel level limits set forth in this subsection shall not apply to such activity, sound source, or device...(a)A steady or quasi-steady sound whose sound level exceeds the limits set forth for the receiving land category in Table 2 when measured at or within the real property boundary of the receiving land;

Full Breakdown
There's no HVAC-specific decibel rule in the Murfreesboro Code. Section 21-106(B)(6) confirms the general exterior sound-level limits apply to any source unless 'decibel level limits and requirements specifically prescribed for such activity, source, or device' exist elsewhere in the Article, and none exist for air conditioning or heat-pump condensers. As continuously running equipment, an HVAC unit is squarely a 'steady or quasi-steady sound' under § 21-106(B)(1)(a), capped at the Table 2 limit for whatever zone the receiving property sits in, for example 53–58 dBA at a home bordering a commercial-zone rooftop unit.
Violations & Fines
Exceeding the zone's Table 2 limit is enforceable under Code § 21-112 and punished per City Code § 1-8, with each continuing half hour of excess noise charged separately.
