• Furnace/Heating Unit: This component generates heat, typically using natural gas, propane, oil, or electricity. It includes a burner, heat exchanger, blower fan, and controls.
• Air Conditioner/Cooling Unit: This unit removes heat and humidity from the air, using refrigerant to cool the air and a compressor to circulate the refrigerant. It includes an outdoor condenser unit and an indoor evaporator coil.
• Air Handler: This indoor unit distributes conditioned air throughout your home. It houses the blower fan, evaporator coil (in air conditioning systems), and air filters.
• Ductwork: This network of ducts carries conditioned air from the air handler to the vents in your rooms.
• Thermostat: This device controls the temperature settings and signals the HVAC system to turn on or off.

     • Check the Thermostat: Ensure the thermostat is set to the correct mode (heat or cool) and that the temperature setting is appropriate. Verify the batteries are working if it’s a battery-powered thermostat.
     • Check the Power Supply: Make sure the system is receiving power. Check the circuit breakers for the furnace and air conditioner and reset them if necessary.
     • Inspect the Air Filter: A clogged air filter restricts airflow and can cause the system to shut down. Replace the filter if it’s dirty.
     • Check the Condensate Drain (AC Only): If the condensate drain line is clogged, the system might shut down. Locate the drain line and check for blockages. You may need to vacuum it out or pour a diluted bleach solution down the line to remove algae.
     • Inspect the Pilot Light (Furnace Only): If your furnace has a pilot light, make sure it’s lit. If not, relight it according to the manufacturer’s instructions.
