In Saudi Arabia, where heat is always a factor, understanding your car’s AC system is crucial. Whether you drive a brand new sedan or an older SUV, a well maintained AC keeps every trip comfortable and prevents surprise repair bills. Here’s how to keep your system working its best—and how to avoid common pitfalls most drivers face.
Many people assume that the AC refrigerant needs to be topped up yearly, but that’s not actually the case. Your car’s air conditioning operates in a sealed system. If the gas ever runs low, there’s likely a leak that needs repair—not just a quick refill. Using the wrong type of refrigerant can also damage modern compressors, so always check your car’s manual before adding anything.
If you notice the AC blows colder air when you’re moving but weakens at a red light or in heavy traffic, the problem probably isn’t with the gas. The most common culprits are a clogged cabin filter, a dirty condenser, or weak cooling fans. Replacing the filter, gently cleaning the condenser, and ensuring the fans run at full speed can restore cooling and improve comfort in all driving conditions.
Today’s drivers have more tools than ever. With a simple OBD-II scanner and a free app, you can read AC pressure and temperature sensors directly from your phone. This lets you spot leaks, check system health, and avoid costly guesswork. Sticking to a maintenance schedule—like checking the cabin filter every six months and inspecting the belt every 80,000 kilometers—will keep your AC working smoothly year round.
