The answer to 'types of preventive maintenance' is that there are several key types of preventive maintenance for HVAC systems that homeowners should be aware of. These include regular air filter changes, annual tune-ups and inspections, duct cleaning, and monitoring refrigerant levels. Performing these routine maintenance tasks can help extend the life of your HVAC system, improve energy efficiency, and prevent costly breakdowns.
Air filter changes are typically recommended every 1-3 months to keep the system running smoothly. Annual tune-ups by a professional HVAC technician will ensure all components are working properly and identify any potential issues before they become bigger problems. Duct cleaning every 3-5 years can improve indoor air quality and airflow. And regularly checking refrigerant levels and topping them off as needed will keep the system operating at peak performance.
