The answer to 'how long will maintenance last' is that the longevity of HVAC maintenance depends on several factors, but with proper care, it can last for many years. Regular professional tune-ups and DIY maintenance tasks like changing air filters can help extend the lifespan of your HVAC system and ensure it operates efficiently.
Most HVAC experts recommend getting your system serviced by a professional at least once a year, usually in the spring or fall before heavy usage. This allows the technician to inspect, clean, and tune-up the components to prevent breakdowns and maximize performance. With annual professional maintenance and attentive DIY care, an HVAC system can often last 15-20 years or more before needing replacement.
