When you’re driving around on a hot summer day, your car’s air conditioner is one of the most important features. However, if it isn’t working properly, you can’t get cool air out of the vents. That’s why it’s important to make sure that everything is running like it should be before you find yourself sweating profusely while stuck in traffic on this particularly scorching day. How to make your car ac colder could be taxing base on its process. If you want to know how to keep your AC running properly and how to keep it cold enough so that you aren’t sweating off pounds of water weight every time you step into your vehicle, here are some tips:

Replace the air filter.

If your air filter is clogged with dirt and dust, it won’t let as much air pass through to the engine. To get the most out of a car’s heater and cooling system, you’ll need to clean or replace the air filter every 30,000 miles or so.

Step 1: Buy a new one at an auto parts store.

Step 2: Remove the old one from inside your car. If it doesn’t pop out easily, don’t force it—you could damage something!

Step 3: Install your new one by slipping its tabs into place around its housing (this might take some wiggling).

Check if the compressor is getting power.

  • Check the fuse.
  • Check the relay.
  • Check the compressor.
  • Check it all, again!

Make sure the compressor clutch is engaged.

One of the most common reasons for a car to be too warm is that the compressor clutch is not engaged. This can happen when you accidentally push the button to turn on your defroster instead of your heater, or if you forget to engage it after having removed snow from your car. To check for this, simply start the car and feel around in front of where you’re sitting (the right side) for a lever with a large button on top—this should be easy to spot even without turning on any lights at night because it usually glows red when pressed. If it isn’t glowing, gently press down until you hear a click sound and then pull back up; this will engage the compressor clutch so that coolant is pumped through your system and into your vents. If there are no levers visible near where you are sitting (usually behind the steering wheel), try looking under either side of both seats as well as directly underneath them; however if these do not work either then chances are good that there is something wrong with how everything has been wired together inside

Look for leaks in the refrigerant lines.

When you start your car and the AC blows warm, it usually means that there is a leak somewhere in the refrigerant line. To check for leaks, spray some soapy water on all of your car’s air conditioning components. If there are bubbles forming around any one of them, then this indicates that there is a leak in the system that needs to be fixed.

To fix leaks:

  • Replace damaged lines and seals with new ones

Clean coils.

To clean the coils, you will need:

  • A vacuum cleaner (a small one is fine)
  • A can of compressed air (the kind you use to clean out your keyboard)
  • A lint-free cloth or paper towel

Check if there’s too much refrigerant in your system.

If there’s too much refrigerant in your system, the compressor can overheat and stop working properly. To check if this is happening, visually inspect the pressure gauge under the hood and on the dash. If they both show high readings (more than 30 pounds per square inch), your car’s AC system might need some extra refrigerant.

After checking those gauges and finding them to be normal, it could be time to call a professional mechanic to add more refrigerant into your vehicle.

Check if there’s not enough refrigerant in your system.

If your car’s air conditioning seems to be running less efficiently than usual, it could mean that you need to add more refrigerant. Check your owner’s manual for the correct amount of refrigerant. You can buy a can of refrigerant at an auto parts store or ask for help from your service provider or mechanic.

Check the pressure in your system using a gauge to ensure that it is operating properly and that there is enough pressure present to force the coolant through the system. If necessary, adjust by adding or removing some liquid from those areas until both pressures are equalized and correct readings are achieved for each side of the system (high side and low side).

Making sure the compressor is working properly and that there isn’t a leak in the lines can help make sure your air conditioner is running properly and keeping you cold on hot days.

If your car’s air conditioner isn’t cooling properly, the first step is to make sure that the compressor, or compressor clutch, is working. Sometimes a blown fuse can cause this problem as well as something like a blown head gasket.

The compressor is the heart of your vehicle’s air-conditioning system. It pumps refrigerant through all parts of your car’s cooling system from one end to another (after being pressurized), causing cool air to flow through vents and out into your car cabin. If there were no compressor, you would never have any cold air coming from inside your car!

Additionally, most people assume the only way to make their car’s air conditioner colder is by turning up the dial. In some cases, that’s true. But if you’re experiencing a weak cooling system or poor cabin temperature, it may be time to get more serious about how your AC works and what it needs to function properly. Here are some simple ways you can make your car’s air conditioner colder on those hot summer days:

Check your compressor belt.

The next step in your troubleshooting process is to check your compressor belt. It’s probably the most common cause of a car ac not working, and it’s also easy to fix. If you hear a squealing sound coming from somewhere behind or under your dash, chances are that that’s the culprit: The pulleys aren’t aligned properly so they’re rubbing against each other instead of smoothly turning together. If this is happening, make sure first that there isn’t something else wrong with your compressor (like a broken fan shroud or bent fins). But if everything else appears fine and you still hear noise when starting up the car, then you need to replace the belt.

Change your cabin air filter.

  • Check the cabin air filter. If it’s dirty, then you need to clean it or change it.
  • Clean the cabin air filter. If you don’t want to buy a new one, then at least give your current filter a good cleaning with an air hose attachment or a vacuum cleaner.
  • Check for debris and mold on the cabin air filter (and replace if necessary). You can do this by looking through and checking every square inch of your car’s interior while everything is turned off (and preferably parked in shade) so that no one gets hurt in case there are any sharp objects that might fall out of place when opening doors/trunk/glove box/etc., which could lead to injury for anyone nearby during these inspections because there would be nothing stopping them from falling any longer than usual due to lack of support from gravity due to being above ground level! Also make sure not leave any loose papers inside cars during this time because they could get sucked up into vents leading straight into engine compartment where they might burn themselves out before we even know what happened!

Check your refrigerant charge

  • Find the signs of leaks.
  • Check the compressor for damage or a factory seal.
  • Inspect the condenser for damage and debris buildup.
  • Check the condenser for debris.

Check the condenser for debris.

The condenser is a heat exchanger, and it cools the air through contact with radiators. If there’s a buildup of leaves and dirt that can’t be removed by brushing them away, you’ll need to clean out the entire radiator system. There are several methods for doing so:

Cleaning it yourself: You can buy a cleaner at any auto parts store, then use an automotive funnel to pour it through one end of your engine block until it’s empty. Turn on your car’s heater while you do this so that any moisture in your system will be forced out into the radiator fins where they’re designed to evaporate quickly. Then let everything dry off before turning off your engine and moving on to step two! Read Also: Air Craft Engine Types

Making car ac colder is easier than it seems if you know what to look for.

Another good way to make car ac colder is to change your cabin air filter. This will not only help improve the airflow of your car’s cooling system, but it will also alert you if there are any other issues with your vehicle’s AC system.

If you want to ensure that you have a properly charged system, one of the best ways would be to get an inspection from a qualified mechanic at a trusted repair shop or dealership near you. If they find something wrong with your AC unit, then the mechanic may recommend fixing this issue before trying anything else that could cause more damage in the future (like overcharging).


Remember, there is no way to make your car ac colder than it is designed to be. If you find that your vehicle’s air conditioner isn’t cooling as well as it should be, get the problem checked out by a professional mechanic. By following these simple steps and having an inspection performed at regular intervals, you can ensure that your air conditioner will continue to keep you cool in even the hottest weather conditions!

In general, making sure your air conditioner is working properly and keeping you cold on hot days is a matter of checking things like the compressor clutch and refrigerant levels. You should also check for leaks in your system so that you don’t waste too much money on repairs or replacements.
