Heating AC Inspection
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. 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.
A top-rated mobile mechanic will come to your home or office to determine the source and cause of the heating or air conditioning issue, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.
While driving around without a proper functioning heating and air conditioning system will certainly be uncomfortable, it is usually not a life or death situation. However, if the defroster is no longer working, this can result in reduced visibility, which can lead to dangerous driving conditions. In most cases, a malfunctioning heating and air conditioning system should be repaired as soon as possible.
