Automotive AC System Parts Online

Thankfully, your HVAC system keeps you and your passengers comfortable no matter how hot or cold it is outside. How it works isn't all that complicated.

Your heating system is quite simple, as a matter of fact. Hot coolant gets drawn from the engine into a heater core. A fan blows over the core's fins and sends warm air into the passenger space.

Cooling is more intricate. First, refrigerant gets pressurized by a compressor, turning it into a hot gas. A condenser cools that down, reverting it back into a liquid. That liquid then runs through an expansion valve that converts it into a low-pressure gas. Then an evaporator cools the gas down so that a fan can blow the cool air through the air vents and into the cabin.

How to Spot AC System Issues

Eventually, even the best AC system parts can go bad. Hoses may degrade or break. Seals can weaken. A compressor can fail. Signs of this include a steamy cabin atmosphere, the syrupy smell of coolant, and an inability to maintain a consistent cabin temperature. If you notice any of these symptoms, inspect your entire HVAC system, starting with your cabin air filter.
