Car Air Conditioning: How It Works and Why Regular Servicing Matters

Published on 3 May 2025 at 23:03

When the sun’s out or you’re stuck in traffic on a muggy day, your car’s air conditioning becomes more than just a luxury – it’s essential for comfort and safety. But like any system in your vehicle, your A/C needs regular maintenance to perform at its best. At TGPP-Autocare Stevenage, we offer professional air conditioning servicing starting from just £59.

 

Here’s everything you need to know about how your A/C system works, why it’s so important, and how we can help keep it in peak condition.

Why Car Air Conditioning Matters

 

1. Comfort on the Road

Your air conditioning system regulates temperature inside the cabin, helping you stay cool and alert – especially during long journeys or in summer heat.

 

2. Safety and Focus

A comfortable temperature improves driver concentration, reducing the risk of drowsiness and fatigue behind the wheel.

 

3. Cleaner Air

Your A/C system filters out dust, pollen, and other airborne pollutants – ideal for allergy sufferers or those with respiratory conditions.

 

4. Protecting Your Investment

A fully functioning, regularly serviced A/C system can boost your car’s resale value and prevent costly future repairs.

How Car Air Conditioning Works

Your vehicle’s air conditioning works through a cycle of refrigerant moving through a closed loop. Here are the main components:

 

  • Compressor – compresses the refrigerant and sends it to the condenser.
  • Condenser – cools the refrigerant into a liquid.
  • Evaporator – absorbs heat from the cabin, cooling the air.
  • Receiver-Dryer – removes moisture and contaminants.

 

 

This cycle not only cools the air but also removes humidity, making the cabin feel fresher and more comfortable

Tips for Proper A/C Use and Maintenance

 

Use it Year-Round

Even in winter, running the A/C for a few minutes every couple of weeks helps keep seals lubricated and prevents leaks.

 

Avoid Long Idling with A/C On

Excessive idling with the air con running can strain your engine and increase fuel consumption.

 

Watch for Musty Smells

A stale or musty smell from your vents often signals bacterial build-up or a clogged cabin filter – both easily resolved with proper servicing.

 

Service Every 1–2 Years

We recommend a full A/C service every 24 months to ensure optimal performance, especially before the warmer months.

Common A/C Problems to Look Out For

 

 

  • Refrigerant Leaks – Lead to reduced cooling efficiency.
  • Clogged Cabin Air Filters – Restrict airflow and trap odours.
  • Faulty Compressors or Electrical Issues – Can cause inconsistent cooling.
  • Bacteria and Mould – Thrive in damp systems, causing unpleasant odours and health concerns.
