Using car AC in hot weather could be a tricky business because the air conditioning system gets a workout during the summer season. When the temperature rises so high that it seems to melt away even the asphalt on the road, you just want to turn the AC at a high speed, hoping to beat the heat. Most people don’t know how the system works, so they use it the incorrect way and burn more fuel than required.

Using Car AC In Hot Weather: Tips To Maximize The Performance

It’s a sunny summer afternoon and you just want to get home after your office. Well, get into the car and you will literally feel like being roasted inside an oven! It takes a few minutes for the AC to kick in and work in a full swing. However, you don’t need to sweat anymore as these tips will help to cool the vehicle faster. Let’s check some best ways of using car AC in hot weather.

Pump Out The Hot Air

Opening the rear windows will pump out the hot air.

Nobody likes to sit inside an oven, even if it’s for just a couple of minutes. So, your first step is to cool off the interior (or getting the super-hot air inside the vehicle out). Before getting into the car, roll down the rear windows and successively open and close the driver’s door for several times. It will force out some hot air within seconds.

Pump Out More While Driving

The AC works much better while you are driving because is compressor runs faster with the rotation of the engine. Switching the AC on before driving will just be a wastage of time and fuel. Keep the passenger seat windows open for half a minute to pump the hot air out of the cabin. Don’t make the mistake of opening up the front windows because it will clear up the front side only while the rear cabin will still be hot.

It will be quicker if your automobile has a sunroof. While driving, keep it open for a minute and all the hot air will rise and get out through the hole.

Turn On The AC At Low Speed

Using Car AC in Hot Weather
Set the AC at the lowest level at first.

You already know that the temperature inside a vehicle tends to be higher than the outside. Set the AC at the lowest temperature so that it draws air from outside the car and cools it down. On the flip side, turning it to the ‘Max’ will force the machine to take air from the passenger’s cabin, which is hotter than the outside air. So, the AC needs to work harder if you set it to the top speed at the beginning.

Change The Dirty Filter

Using car AC in hot weather most efficiently does not only need tuning up the system but also checking on a few components. You won’t get the optimal airflow if the cabin’s air filter is dirty. Check it on a regular basis to see if it’s clear or collecting dirt. You will need to change it if it becomes grimy and greasy. It’s relatively easier to reach and change in newer cars, but you have to take the help of a mechanic in case of an older model.

Turn off the auto system

The AC in newer vehicles turns off automatically when the engine is not running. It saves fuel but does not help in hot weather when a lengthy traffic light could make you all sweaty. Switch off the feature so that the inside is cool even when you have to stop the engine for a few minutes.

    Beautiful tips to maximize AC capacity and save fuel. Having a broken down air conditioner during hot weather when you’re in the middle of the road is such an terrible experience. It happened to me once on my road trip across my country when my RV air conditioner compressor not coming on. It took me almost one day to find the root and have the mechanics guy fixed it.
