The majority of vehicles today feature modern HVAC systems to supply passengers with the luxury of controlling the temperature, subsequently increasing their comfort. This is especially helpful during seasons of extremely hot or cold weather, where driving without an AC or heating system would make for an unpleasant trip. Having an AC and heating system that functions properly is a must for most car owners, as any car should be equipped with this feature to avoid an uncomfortable drive.

What Causes an A/C and Heating System to Break?
Anything can break or become worn out over time, especially when it comes to parts of a vehicle that are regularly used. Deteriorating hoses, lack of proper lubrication, and a host of other factors can cause your system to fail, which is why regular HVAC maintenance and system checks are important to prevent these issues before they happen.
Common Signs Your A/C or Heating Needs Repair
If your A/C and heating system exhibits any of the following signs, it might be an indicator that it needs repairing:
- Temperature of the air coming through vents does not match that of temperature setting
- Poor air flow, even on high settings
- Windshield remains foggy on defrost setting
- Air vents produce musty or mildew smells
- Unusual noises when the system is in use, such as squealing or grinding
- System completely fails when vehicle is stationary
How Does an A/C and Heating System Work?
Your car’s HVAC system operates through several interworking parts. Basically, to generate cool air, your car’s compressor begins pumping refrigerant, which is a fluid, through the coil system when the A/C is turned on. The compressor is powered by your car’s drive belt, which is connected to the crankshaft. While this is happening, the expansion valve restricts the flow of the refrigerant and reduces the pressure that causes the temperature to lower. Lastly, your car’s fan blows the cool air through the vent system into the interior of the car.
For the generation of heat, radiator coolant is guided through the heater core before entering the radiator, where the fan pushes the heated air through the air vents.
