How to deal with heat trapped in your car

How to deal with heat trapped in your car 21st July 2014

Driving in summer can get particularly uncomfortable as temperatures rise and the heat in your car builds up.

Many will know the feeling of going to get in their car after it has been parked up for some time to be hit by a wave of heat as you climb into it. Once you start driving, you want to get the heat out of your car as soon as possible to avoid an uncomfortable car journey.

If you can't release trapped heat in your car then expect it to only get worse on a hot day. Luckily there are steps you can take to improve this situation.

First and foremost, the quickest way to get trapped heat out of your car and get a good cool breeze is by switching on the air con. Most modern cars have it and it is certainly a useful tool for keeping your car cool and also for clearing your windscreen if it steams up.

However, people may be concerned about how much using the air con costs them in fuel. The best way to minimise the amount of fuel used to power the system is to get an air conditioning service regularly.

Over time, air con systems can permeate gas from the system, meaning your car has to work harder to get it working. Therefore, it is best to get it serviced roughly every two years.

What's more, if you leave your air con unserviced for a long time then you may find it runs out of gas and ends up just blowing warm air through.

To lower the amount of heat that gets trapped in your car to start with, consider carefully where you park your car and try to make sure it is out of the sunlight. If you have sunlight beaming through your windows then this will cause a greenhouse effect, causing more heat to get into your car. Therefore, if you have a garage, park your car in here. If you are on the move, try to put your vehicle in car parks that are under cover or, if you have to park outdoors, look for somewhere shaded by trees.
