• Blower: This is the fan that draws air from your home, passes it through the system, and distributes it back into your living spaces.
• Coils: These contain the refrigerant that absorbs heat (cooling coil) or releases heat (heating coil) to control the air temperature.
• Filters: These trap dust, pollen, and other airborne particles, improving air quality and protecting the other components.
• Ductwork: This network of pipes and vents distributes the conditioned air throughout your home.
• Drain Pan: This collects the condensation that forms on the cooling coil and drains it away.
• Electrical Components: These include the motor, control board, and wiring that power and regulate the system.

• Symptoms: Weak airflow from vents, uneven heating or cooling, or the unit not blowing air at all.
• Causes:
  • Clogged air filter: A dirty filter restricts airflow.
  • Blocked vents or ductwork: Obstructions like furniture, debris, or collapsed ductwork can impede airflow.
  • Blower motor failure: The motor might be malfunctioning or not receiving power.
  • Closed dampers: Dampers control airflow to different areas of the building. If they are closed, airflow will be restricted.
• Troubleshooting:
  • Check and replace the air filter: This is the first and easiest step. Replace the filter regularly (every 1-3 months) based on the manufacturer’s recommendations.
  • Inspect vents and ductwork: Make sure vents are not blocked and that ductwork is free from obstructions.
  • Check the blower motor: If the motor is not running, check the circuit breaker and ensure it’s not tripped. If the breaker is fine, the motor might need to be replaced (call a professional).
  • Check dampers: Ensure that dampers are open.

  • Faulty thermostat: The thermostat may not be sending the correct signals to the air handler.
  • Electrical issues: A blown fuse or a malfunctioning control board can prevent the unit from operating correctly.
  • Heating element failure (for electric heat): If the unit uses electric resistance heating, a failed element can prevent heating.
• Troubleshooting:
  • Check the thermostat: Make sure it’s set to the correct mode (heat or cool) and that the temperature setting is appropriate.
  • Inspect the coils: Clean dirty coils with a coil cleaner. If coils are frozen, turn off the unit and let them thaw.
  • Check for refrigerant leaks: This requires a professional technician.
  • Check the electrical components: Inspect fuses and the control board for any signs of damage. If you are not comfortable working with electricity, call a professional.
