'I'm a mechanic - if your car smells like this, get it repaired right now'

A motoring expert has urged drivers who encounter a certain smell to get their car checked in order to prevent feeling unwell on long journeys. With many parts of the country recently experiencing warm and sunny spells, a significant number of motorists have recently switched on their air conditioning for the first time in months. However, Andrew Jervis, CEO of ClickMechanic, urged drivers using the feature for the first time in a while to take action as soon as they encounter a certain smell.

He said: "Musty or damp smells when you turn on the air conditioning is the biggest sign your air con needs cleaning. If the air vents are dirty, this can also be a tell-tale sign. However, there are more worrying signs, too, such as sneezing, coughing and a sore throat when the air con is running. Every year, we see an increase in drivers complaining about musty-smelling air con or unexplained allergy-like symptoms when in their car. A simple maintenance check and filter replacement can make a world of difference."

Whilst many take the air conditioning system in their car for granted, it must be regularly serviced in order to continue working correctly - particularly if it has not been used for months on end.

In particular, mold and bacteria can form within the system, which can be blown into the cabin as soon as the system is turned on, resulting in occupants facing a number of health issues.

As a result, it is a good idea for drivers to check for any musty smells when turning on their car's air conditioning for the first time in a while, taking it to a professional for a service if an unpleasant odour is present.

Andrew warned that those who do not get their air conditioning system fixed could be putting themselves and passengers at risk of serious health problems, particularly if they suffer from respiratory conditions like asthma.

He said: "Studies have shown that bacteria, viruses, fungi, and yeasts are commonly found in car air conditioning systems. These can circulate in the air, potentially leading to respiratory infections, allergic reactions, and other health issues.

"Breathing in mould can exacerbate existing respiratory conditions, and trigger allergies including asthma."
