How Your Car's Air Conditioning System Works
Understanding your AC system helps you recognize problems early:
The AC Refrigerant Cycle
- Compressor
- Driven by serpentine belt from engine
- Compresses refrigerant gas
- Creates high-pressure, high-temperature gas
- Most mechanically complex AC component
- Condenser
- Receives high-pressure refrigerant from compressor
- Releases heat to surrounding air (front of vehicle)
- Refrigerant cools and becomes liquid
- Similar function to vehicle radiator
- Receiver-Drier (Accumulator)
- Stores excess refrigerant
- Removes moisture from system
- Filters debris
- Maintains pressure regulation
- Expansion Device (Orifice Tube or Expansion Valve)
- Precise metering component
- Reduces pressure of refrigerant
- Controls refrigerant flow to evaporator
- Coordinates cooling with engine load

Customer Reviews
What Ryde Drivers Say
Have carried out multiple repairs and scheduled services on our vehicle. Extremely helpful and quick to turn the work around. Very reasonable pricing and always feel we’ve only paid for the work that was really required. Thanks team. Great to see a small business doing well and servicing customers
Andrew Wyles
I live close to where the Ryde Top Ace workshop is. My car battery had stopped working after I had been overseas. The Top Ace personnel were kind enough to come to my home within a short time of my request and jump start my battery. Very obliging and prompt. I would recommend their services to anyone.
Jeniffer de sayrah
I had an excellent experience at Top Ace in West Ryde. From start to finish, their team was professional, honest, and truly went above and beyond. I came in for a routine service + diagnostics, and Amir the owner took the time to explain all the issues in clear, non-technical terms. The work was done quickly, they used quality parts, and when I picked up the car it ran smoother than ever. They also handled the paperwork for my pink/blue slip with no hassle.
