The answer to 'lifespan of preventive maintenance' is that proper preventive maintenance can significantly extend the lifespan of your HVAC system. Regular maintenance, such as changing air filters, cleaning coils, and tuning up the system, can help your HVAC equipment last 15-20 years or more with proper care. Without preventive maintenance, the average lifespan of an HVAC system is only 10-15 years.
Preventive maintenance helps your system run more efficiently, use less energy, and avoid costly breakdowns. By catching small issues early, you can prevent them from turning into major repairs down the line. This saves you money in the long run and ensures your home stays comfortable for years to come.
