There are multiple types of heating systems, including forced air, boilers, radiant, etc.; this example will concentrate on gas forced air systems.
The forced air systems include the following components (and often more): control unit, filters, gas valve, mixing chamber, ignition unit, burners, heat exchanger, blower/motor, and ductwork.
If neither of these works, call for service.
Exhaust units typically contain ductwork and a blower/motor. If it is not functioning see if the circuit breaker is off or tripped. Turn breaker ON and/or reset. If unit is still not functioning correctly, call for service.
Air conditioning units have the same basic components and follow the same cycle as refrigeration units. However, an air conditioner is cooling a much bigger, less enclosed “box”. It is also not trying to reduce the temperature to the level of a cooler or freezer.
If these remedies do not resolve the issue, call for service.
Refrigeration systems are closed loop operations, and maintain the colder temperatures since they are within a closed, insulated box. Low temp refrigerants are used for freezers and medium temp refrigerants are used for coolers. They contain at least (and usually many more) components: a compressor, a metering device, a hot (condenser) coil, a cold (evaporator) coil, fans (for the condenser and evaporator coils) and a control unit (thermostat). The cycle is as follows:
If none of these work, call for service.
If these remedies do not work, call for service.
