The answer to 'how long will maintenance last' is that regular HVAC maintenance should be performed annually to keep your system running efficiently and extend its lifespan. During an annual tune-up, an HVAC technician will thoroughly inspect your system, clean components, check for proper airflow, and make any necessary adjustments or minor repairs. This preventative maintenance helps catch small issues before they become bigger problems, and can add several years to the life of your HVAC equipment.
Most HVAC systems have a typical lifespan of 15-20 years with proper maintenance. However, the actual longevity can vary depending on factors like the system's quality, how often it's used, and the local climate. Skipping annual tune-ups or neglecting maintenance can significantly reduce your system's lifespan, sometimes by half or more.
