The answer to 'lifespan of preventive maintenance' is that with proper preventive maintenance, HVAC systems can last 15-20 years or more. Regular tune-ups, filter changes, and other maintenance tasks help keep your system running efficiently and extend its lifespan. Without preventive maintenance, HVAC systems typically only last 10-15 years before needing replacement.
Preventive maintenance is crucial for maximizing the lifespan of your HVAC system. By catching small issues early and keeping the system well-maintained, you can avoid more costly repairs down the line and ensure your system continues to heat and cool your home effectively for years to come.
