The answer to 'how long will preventive maintenance last' is that preventive HVAC maintenance typically lasts for 1-2 years, depending on the specific system and usage. Regular maintenance, such as changing air filters, cleaning coils, and inspecting components, helps ensure your HVAC system operates efficiently and extends its lifespan. Neglecting preventive maintenance can lead to more frequent breakdowns, higher energy bills, and a shorter overall lifespan for your HVAC equipment.
Homeowners should have their HVAC system serviced by a professional technician at least once a year, usually in the spring or fall when the system is not in heavy use. This allows the technician to identify and address any potential issues before they become major problems. Properly maintaining your HVAC system can help it last 15-20 years or more, saving you money on energy costs and costly repairs in the long run.
