Early warning signs
- Air that isn’t as cold as it used to be, or takes a long time to cool down.
- Weak airflow from the vents.
- Unusual noises when you switch the A/C on — often a sign of compressor trouble.
- A musty smell from the vents.
- Water where it shouldn’t be inside the cabin.
Common causes
A blocked condenser
The condenser sits at the front of the car and releases heat from the refrigerant. Leaves, road debris and dirt can block it, so the system can’t shed heat and the air coming out isn’t cold.
A failing compressor
The compressor is the heart of the A/C system. Unusual noises when the A/C is on are a classic sign it needs attention.
Why spring is the right time
A/C systems are intricate, and small problems tend to become expensive ones if they’re left. Getting it checked before the hottest months means you’re not waiting for an appointment in the middle of a heat wave.
Don’t forget the cooling system
Heat and traffic also stress the engine’s cooling system. If your coolant is due, have it done at the same time — see fluids flush and what to do if your car overheats.
Hybrids too
Hybrid A/C systems are different, and our shop has the tools to diagnose and repair them. See hybrid car maintenance basics.
