The answer to 'how long does maintenance last' is that HVAC maintenance typically takes 1-2 hours for a standard residential system. During this time, an HVAC technician will perform a comprehensive inspection, cleaning, and tune-up of your heating and cooling equipment. This includes checking refrigerant levels, testing electrical components, cleaning the condenser coils, and ensuring all parts are functioning properly.
Regular HVAC maintenance is recommended 1-2 times per year, typically in the spring and fall before the peak heating and cooling seasons. Maintaining your system on this schedule helps ensure it runs efficiently and extends its lifespan, potentially saving you money on energy bills and avoiding costly breakdowns.
