The answer to 'when to service HVAC repair' is that HVAC systems should be serviced regularly, typically once or twice a year, to maintain optimal performance and efficiency. Regular maintenance helps identify and address any issues before they become major problems, extending the lifespan of your HVAC equipment.
The recommended frequency for HVAC maintenance is to have a professional technician service your system once in the spring, before the cooling season, and again in the fall, before the heating season. This allows the technician to inspect, clean, and tune-up the system, ensuring it is running safely and efficiently. Additionally, you should change your air filters every 1-3 months, depending on usage and indoor air quality.
