Emergency HVAC repair or wait until morning?

I’m trying to decide whether I should call for emergency repair or just wait until regular business hours. The system is partially working, but not properly cooling or heating. How do you usually make this call?

Had a similar situation one November evening when the system was still running but wasn’t properly heating the house, and it really wasn’t obvious at first whether it could wait or not. After a short time it became clear the performance kept dropping instead of stabilizing, which made me uncomfortable leaving it until morning. A technician from electrical emergency repair services by Product Air later mentioned how partial operation can sometimes hide deeper electrical issues, especially when paired with DOE Energy Skilled™ recognition standards in diagnostics. Since then I tend to call earlier rather than wait when something feels inconsistent.
