Question: 1 / 400

How often should HVAC systems generally be serviced?

Once a year

Twice a year

HVAC systems should generally be serviced twice a year, which allows for thorough maintenance checks to ensure that the system operates efficiently throughout both the heating and cooling seasons. This biannual servicing typically includes tasks like cleaning or replacing filters, checking refrigerant levels, inspecting electrical connections, and ensuring that all components are functioning properly.

Regular maintenance helps in extending the lifespan of the system, improves energy efficiency, and can prevent costly repairs down the line. By having serviced both in spring before cooling use and in the fall before heating use, technicians can ensure the system is ready for peak performance when it's needed the most. Regular check-ups can also help to identify any small issues before they escalate into larger, more expensive problems, ultimately contributing to better indoor air quality and comfort.
