Having your car's air conditioning (A/C) serviced regularly is about much more than keeping cool in summer.
1. It Maintains Cooling Performance
Over time, A/C systems naturally lose a small amount of refrigerant through seals and pipe connections. Even losing 10-15% can noticeably reduce cooling performance. A service checks refrigerant levels and restores them if necessary.
2. It Helps Demist Windows
Your A/C removes moisture from the air as well as cooling it. A properly functioning system clears misted-up windows much faster during wet and cold weather, improving visibility and safety.
3. It Reduces Bad Smells
The evaporator inside the system can become a breeding ground for mould, bacteria and fungi, causing the musty smell many drivers notice when they switch the A/C on. An A/C service often includes an antibacterial treatment to eliminate these contaminants.
4. It Protects Expensive Components
The refrigerant carries lubricating oil around the system. If refrigerant levels get too low, components such as the compressor can wear prematurely. A compressor replacement can easily cost several hundred pounds or more.
5. It Can Improve Fuel Efficiency
An A/C system that is low on refrigerant may have to work harder, increasing the load on the engine. While the savings are usually modest, a properly functioning system operates more efficiently.
6. It Identifies Leaks Early
During a service, technicians can check for leaks, damaged pipes, worn seals, and condenser damage before they develop into costly repairs.
How Often?
For most vehicles:
A/C service: every 2 years
Cabin/pollen filter: every 12 months or as specified by the manufacturer
Use the A/C year-round: run it for at least 10 minutes every couple of weeks, even in winter, to keep seals lubricated
Signs Your A/C Needs Attention
Air isn't as cold as it used to be
Bad or musty smells
Windows take longer to demist
Unusual noises when the A/C is switched on
A/C compressor cycles on and off frequently
Visible oily residue around A/C pipes or condenser
