We rarely give any thought to the heating and air conditioning systems in our cars until they stop working. These systems help keep the cabin of the vehicle warm in winter and cool in summer. Maintaining the heating and air conditioning system is key to a comfortable ride, regardless of the season.

While the major function of these systems is for the comfort of the passengers, they are also integral to the defroster system, which keeps the windshield clear and ensures good visibility on a cold or snowy day. Driving with reduced visibility can greatly increase the odds of an accident.

How this system works:

Heating System

The heating system in a car consists of a number of components. The heater core, heater hoses, heater control valve, blower fan/motor, and the control panel in the cabin are the key parts of the system. The heater core is a like a small radiator mounted under the dash. It has an inlet and outlet to allow the flow of coolant through the core, the heater control valve regulates the amount of hot engine coolant that goes through the heater core. Finally, the heat generated by the heater core is blown into the cabin by the blower motor, which is controlled by the control panel in the cabin.

Air Conditioning

The air conditioning system uses a compressor, condenser, evaporator and an expansion valve. Refrigerant (R-134a or HFC-134a), is compressed in the compressor system which transforms it into a hot gas. The hot gas is then cooled to a liquid state in the condenser and sent to the expansion valve. When the gas is forced through the expansion valve, it returns to a gas state, which is rapidly cooled in the evaporator. The blower fan blows over the evaporator and sends the cold air into the cabin via the vents. This system is controlled by the control panel in the cabin.

Common reasons for this to happen:


  • Low Coolant Levels: The hot air that comes into the vehicle is a byproduct of the heat of the coolant in the engine. If the coolant levels are low or the fluid is contaminated, it can lead to a poorly functioning heating system. In most cases a leak is to blame.

  • Blown Fuse: While a blown fuse can be a quick fix when it comes to the heating system, in most cases it is just a symptom of a larger problem. If the same fuse continues to blow on regular basis the vehicles heating system should be inspected for a bigger issue.

  • Bad Heater Core: The heater core is basically a mini radiator located behind the dashboard. There are a number of things that can cause a heating core to malfunction, it may be clogged due to contaminants in the anti-freeze. Hoses can crack, leak or become loose. The control valve can also get stuck. A bad heater core will result in zero heat.

  • Air Pockets in the Heater Core or Hoses: If there is air in the cooling system in most cases there will also be a leak. Air in the system can create air pockets that will interrupt the flow of coolant through the heater core. The air can be bled from the system to resolve this issue.

  • Malfunctioning Thermostat: The thermostat functions as a shut-off valve between the radiator and the engine. The thermostat is closed as the car warms up. When the engine is warm, the thermostat opens to circulate the anti-freeze. A malfunctioning thermostat will often stick open, resulting in an engine that doesn’t warm up so the heating system doesn’t have enough hot air to warm the cabin.

  • Bad Blower: The electric blower motor pushes the hot air out into the cabin and if it is malfunctioning the heat will not make it into the vehicle cabin. A bad blower can be caused by a blown fuse, a blower speed controller that is not working properly or the motor itself may be shot.

Air Conditioning

  • Loss of Refrigerant: If the air is no longer coming out cold, this could indicate that the refrigerant needs to be recharged or there is a leak in the system. Refrigerant problems are one of the most common reasons an air conditioning system isn’t working properly. The system will need to be recharged from time to time with new refrigerant, as it loses roughly 15 percent every year. A leak can also cause this problem as the system loses refrigerant at the leak site.

  • Bad Compressor: The compressor works very hard and they run hot due to the internal pressure they must produce. All of this hard work means that a failing compressor is a very common problem with a vehicles air conditioning system. A loud knocking or squealing noise will often point to compressor problems, as will a lack of cold air or the air conditioning just not working at all. This should be repaired immediately as it can affect other parts and run up the cost of the repair.

  • Leaking Hoses: The air conditioning system relies on a variety of hoses and if they are loose or leaking you could experience a loss of cooling due to leaking refrigerant. Leaking hoses should be replaced as soon as p
