The answer to 'when to service maintenance' is that HVAC systems should be serviced regularly, typically once or twice a year, to ensure optimal performance and energy efficiency. Regular maintenance can help extend the life of your HVAC equipment, prevent costly breakdowns, and ensure your home stays comfortable.
The recommended frequency for HVAC maintenance is to have a professional service your system in the spring and fall, before the peak heating and cooling seasons. This allows them to check for any issues, clean the components, and make any necessary adjustments or repairs before you need to rely on your HVAC system the most.
