  • Check the batteries in your thermostat. Replace them if necessary.
  • Make sure the thermostat is getting power.
• Check the Breaker:
  • Go to your electrical panel and check the circuit breaker for the HVAC unit. If it’s tripped, reset it.
  • If the breaker trips again, there may be a more serious electrical problem, and you should call a professional.
• Check the Air Filter:
  • A clogged air filter restricts airflow and can cause the unit to overheat or malfunction. Replace the filter regularly (usually every 1-3 months).
• Check the Blower Motor:
  • Listen for the blower motor to turn on when the system is activated. If it doesn’t, there might be a problem with the motor or its wiring.
• Check the Condensate Drain Line (AC):
  • For air conditioners, a clogged drain line can prevent the unit from cooling properly. Inspect the drain line for blockages and clear them if necessary.

• Inspect Ductwork:
  • Check for leaks or obstructions in the ductwork. Seal any leaks with duct tape or mastic sealant.
  • Ensure the vents are open and not blocked by furniture or other objects.
• Check Refrigerant Levels (AC):
  • Low refrigerant levels can cause the air conditioner to blow warm air. This requires a professional to diagnose and repair.
• Check for Ice on the Evaporator Coil (AC):
  • If the evaporator coil is frozen, it indicates a problem with airflow, refrigerant, or another component. Turn off the AC and let the ice melt before investigating further.
• Check the Furnace Burners:
  • For furnaces, ensure the burners are igniting properly. If they’re not, there may be a problem with the gas supply, igniter, or flame sensor.
