When altering supporting frameworks for HVAC installations, the primary concern centers on the stability of the building structure. This involves ensuring that any modifications made to support the HVAC system do not compromise the integrity of the building. Properly designed and implemented framework alterations prevent potential hazards such as structural failure, which can arise from added loads, improper distributions of weight, or inadequately secured systems.

Maintaining structural stability is crucial as it affects the safety and usability of the entire building. Other considerations, such as efficiency of the HVAC system, compliance with local codes, and longevity of the HVAC components, are also important but they stem from or are secondary to the fundamental need for a stable and secure structure. Without a stable base, no amount of efficiency, code compliance, or component durability can ensure the system will operate safely and effectively.
