The answer to 'which is better preventive maintenance or' is that preventive maintenance is generally better for HVAC systems. Preventive maintenance involves regularly scheduled service and inspections to identify and address potential issues before they become major problems. This helps extend the lifespan of your HVAC equipment, improve energy efficiency, and prevent costly breakdowns.
In contrast, reactive or repair-based maintenance only addresses issues after they occur. This can lead to more extensive and expensive repairs, as well as unexpected downtime for your HVAC system. Preventive maintenance is a proactive approach that helps you stay ahead of potential problems and maintain optimal performance.
