The answer to 'types of preventive maintenance' is that there are several key types of preventive maintenance for HVAC systems that homeowners should perform regularly. This includes changing air filters every 1-3 months, cleaning the condenser coils annually, and scheduling professional tune-ups and inspections every 6-12 months. Proper preventive maintenance helps extend the lifespan of your HVAC system, improve energy efficiency, and avoid costly breakdowns.
Preventive maintenance tasks can be broken down into DIY jobs that homeowners can do themselves, as well as professional maintenance that should be handled by a licensed HVAC technician. DIY tasks like changing air filters and cleaning coils are important, but more complex jobs like refrigerant charging, duct cleaning, and major component replacements should be left to the pros.
