<h2>How do your car&rsquo;s A/C and heater Work?</h2> Your car's air conditioning (A/C) and heating systems work together to maintain a comfortable interior environment.&nbsp; 1. Air Conditioning System: Compressor: The A/C system starts with the compressor, which compresses refrigerant gas, raising its pressure and temperature. Condenser: The hot, high-pressure refrigerant then flows to the condenser, where it releases heat to the outside air and transforms into a liquid. Expansion Valve: The liquid refrigerant passes through the expansion valve, where it experiences a drop in pressure, turning it into a cool gas. Evaporator: This cool gas travels to the evaporator inside the cabin, absorbing heat from the interior air and cooling it down. A blower fan circulates the cooled air into the car.&nbsp;2. Heating System: Engine Coolant: The heating system uses engine coolant, which absorbs heat from the engine. As the engine runs, the coolant circulates through the heating core. Heating Core: The heating core functions like a small radiator. The warm coolant passes through it, heating the air that blows through the vents. Blower Fan: A fan blows air over the heating core, distributing warm air into the cabin.<h2>Diagnosing air conditioning issues in your vehicle</h2>&nbsp;<ul><li>Reduced Airflow or Lack of Cool Air: This may suggest a defective blower motor or a blocked cabin air filter.</li><li>Poor Cooling Performance: If the AC isn&rsquo;t providing adequate cooling, a refrigerant leak could be the cause, often accompanied by oil spots or hissing sounds.</li><li>Strange Noises from the AC Compressor: If you hear grinding or rattling when the AC is on, it may indicate a failing compressor or internal damage.</li><li>AC Failing to Activate: If the system doesn&rsquo;t turn on, the problem might be related to electrical issues or a malfunctioning compressor.</li><li>Musty Odor: A bad smell when the AC operates could point to mold or mildew buildup in the AC evaporator core.</li></ul><h2>High-performance heating &amp; air conditioning parts at A-Premium</h2>&nbsp;At A-Premium, we prioritize quality in our heating &amp; air conditioning components to ensure your vehicle's comfort and performance.
