What Should I Do If My Car’s Air Conditioning Isn’t Working?
Having a functional air conditioning system in your car is essential, especially during warm weather. If your car’s AC isn’t cooling as it should, it could indicate several potential issues. At Hon Car Service Southampton, we offer expert air conditioning diagnostics and repairs to ensure your vehicle remains comfortable. If you’re looking for a car service garage near me or MOT and service near me, we’re here to help.
How Does Your Car’s Air Conditioning System Work?
Your car’s air conditioning system operates by circulating refrigerant through a series of components, including:
Compressor – Pressurises the refrigerant to circulate through the system.
Condenser – Releases heat and helps cool down the refrigerant.
Expansion Valve/Orifice Tube – Regulates refrigerant flow into the evaporator.
Evaporator – Absorbs heat and cools down the air before it enters the cabin.
If any of these components fail, your AC may stop working efficiently.
Common Causes of Air Conditioning Problems
Several factors can cause your car’s AC to malfunction, including:
Low Refrigerant Levels – A common issue that prevents the system from cooling properly.
Clogged or Dirty Air Filter – Restricts airflow, reducing cooling efficiency.
Faulty Compressor – If the compressor is failing, the AC won’t function correctly.
Electrical Issues – Problems with wiring or fuses can impact system performance.
Mold or Bacteria Build-up – Can cause bad odors and reduced airflow.

What Should You Do If Your Car’s AC Isn’t Working?
