When your heating system isn't operating, do not call a HVAC company until you do these:
1) if thermostats is blank, replace batteries. Weak batteries don't allow thermostat to send a signal to air handler.
2) check your air filters. Dirty filter can choke air handler air intake and it won't allow it to heat properly.
3) check electrical breakers. If In Off, turn it back to On. If tripped, sign of a short. Try to reset. If that doesn't work, then call a HVAC tech.
Do those and you may save a service and repair fee!
