An HVAC system typically lasts between 15 to 25 years, depending on usage and maintenance.  Regular maintenance is crucial to ensure optimal performance and longevity. Neglecting routine upkeep can lead to decreased efficiency, higher energy costs, and unexpected breakdowns, potentially resulting in costly repairs or premature system replacement. Additionally, poorly maintained HVAC systems can compromise indoor air quality, affecting occupant health and satisfaction. To protect your investment and ensure tenant comfort, it's advisable to establish a regular maintenance schedule with a qualified HVAC professional. This proactive approach helps identify and address issues early, ensuring the system operates efficiently and reliably throughout its lifespan. hvac maintenance commercial hvac maintenance hvac preventative maintenance Atlanta Marietta
