HVAC systems typically exhibit a lifespan ranging from 10 to 15 years.

Nonetheless, the efficiency and performance of these systems tend to decline with age. Consequently, it is advisable to commence the search for a replacement after approximately a decade. Even in the absence of significant issues, modern HVAC systems offer the advantage of enhanced energy efficiency, resulting in monetary savings on utility bills.

Furthermore, these systems commonly come equipped with warranties spanning a decade, thereby alleviating concerns regarding replacement for a considerable duration.
