The answer to 'lifespan of maintenance' is that properly maintaining your HVAC system can significantly extend its lifespan. With regular professional tune-ups and DIY cleaning, most HVAC systems can last 15-20 years or more. Neglecting maintenance, however, can reduce the lifespan to as little as 5-10 years.
Routine HVAC maintenance typically includes tasks like replacing air filters, cleaning coils, checking refrigerant levels, and inspecting electrical components. Staying on top of these tasks can prevent major breakdowns and ensure your system runs efficiently for years to come.
