How To Make Your Car AC colder: Get Your Car AC Blasting Cold Air
If you want to make your car AC colder, you’re at the right place. In the hot summer of the UAE, nobody wants to sweat like a sauna while driving. It should be a feel-good experience but often gets ruined when you’re not getting that fresh, cool breeze of your car’s AC.
Various factors affect your AC’s cooling power. So, if you want to get the maximum cooling out of your AC, scroll down and find your solutions.
Common Reasons Why Your Car AC Is Not Blowing Cold Air
Before we explore the solutions, let’s first consider why your car’s AC might not be blowing air. There are explanations for this problem:
- Insufficient Refrigerant: One prevalent cause is having low refrigerant levels in the AC system. With time, the refrigerant can gradually leak out of the system, thereby causing low cooling efficiency.
- Clogged Cabin Air Filter: A dirty or clogged cabin air filter can hamper airflow and cut down on the cooling muscle of your AC. Giving that filter a good cleaning or swapping it out is essential for peak performance.
- Faulty Compressor: The compressor is the heart of the AC – it squeezes that refrigerant and moves it around. Any issue in the compressor will have you wishing for colder air.
- Leaks in the AC System: Any leaks in the AC system can drain the refrigerant, leaving you with no cold air. Finding and fixing these leaks is essential to get your AC’s cool air back.
Now that we know what’s causing the problem, let’s wrangle up some solutions!
Steps to Make Your Car AC Colder
1. Checking the Refrigerant Levels
The first thing that you need to do is check the refrigerant levels. Here’s how to go about it:
- Locate the Service Ports: The service ports usually hang out under your car’s hood. You might have to dust off your owner’s manual or a repair guide to find the exact spot.
- Attach the Gauge: Get your low-side gauge latched onto the low-pressure service port and the high-side gauge onto the high-pressure service port. Make sure that they are nice and snug.
- Read the Gauge: Fire up the engine and crank up the AC to the max. Take a gander at the gauge readings on the low and high sides. They should be sittin’ pretty in the range the manufacturer says is good. If they’re too low, that spells a low refrigerant level.
- Recharge the AC System: If the refrigerant levels are running low, it’s time for a recharge. Follow the instructions on the refrigerant canister to safely add some to your AC system. And don’t forget your gloves and goggles – that refrigerant’s no joke.
Remember, if you are hesitant to do this yourself, it’s a good idea to let a professional handle it.
2. Cleaning or Replacing the Cabin Air Filter
If you got yourself a clogged-up cabin air filter, that’s like putting a kink in the hose for your AC. To fix it, do this:
- Locate the Cabin Air Filter: You can find that cabin air filter lurking behind your car’s glove box or under the dash.
- Remove the Old Filter: Open that glove box and drop it down. Find that cabin air filter housing and ditch the clips or screws holding the cover in place. Remove the old filter.
- Clean or Replace the Filter: If your filter is dirty but still has some life left, dust it off with compressed air or a gentle tap to remove the junk. If it’s too far gone, swap it out for a fresh one that’s the same size and type.
- Reinstall the Filter: Put that cleaned or new filter back in the housing, making sure it’s lined up right. Snap on the cover with the clips or screws. Pop the glove box back up and lock it in place.
Cleaning or switching out the cabin air filter at regular times will keep the airflow rolling and that AC blowing cold air like never before.
3. Inspecting and Repairing the Compressor
Your compressor has got a big job of compressing the refrigerant and spreading it around. To check on it and fix it up, here’s what to do:
- Visually Inspect the Compressor: Track down that compressor under your car’s hood and give it a nice scan. Look for any telltale signs of trouble, like leaks, cracks, or connections that are all out of sorts.
- Check the Compressor Clutch: Start the engine and turn on the air conditioning to inspect the compressor clutch. Focus your attention on the compressor clutch located at the compressor’s front. It should be rotating and stopping on a regular basis. If not, there can be an issue with the clutch or electrical contacts.
- A Compressor Test: If you think there might be an issue with the compressor, you can quickly test it with a multimeter. Set the multimeter to the resistance or continuity mode to measure the resistance between the compressor terminals. The numbers may differ depending on the kind of compressor you have, so find out the exact figures by consulting your repair manual.
- Repair or Replace the Compressor: If there’s a problem with the compressor, it’s best to replace it with a new one. Since it’s a complicated task, you should leave it to the experts.
Checking up on your compressor and fixing any issues will give you the cool air you’re after.
4. Checking for Leaks in the AC System
Leaky parts in your car’s AC system could be the reason that it’s not giving cold air. Follow these steps to resolve this matter:
- Inspect Visible Components: Inspect the AC system parts like hoses, fittings, and connections. Look for any signs of leaks, like oil stains, wet spots, or hints of refrigerant.
- Use an Electronic Leak Detector: Those electronic leak detectors are handy for sniffing refrigerant leaks. Just follow the instructions from the manufacturer to use it right. Run it slow along the AC system parts, especially where leaks like to hang out.
- Check for Bubbles: Another trick for spotting leaks is to slather on a soapy mix to the AC parts. Start the engine and crank up the AC. If there’s a leak, you’ll see bubbles popping up right where the problem is.
- Repair the Leaks: If you sniff out any leaks, don’t drag your boots on fixing them up. Depending on how bad the leak is and where it’s hiding, you might need to swap out a part or use some sealant.
Finding and fixing leaks will help your car’s AC system to blow cold air.
5. Recharging the AC System
If your car’s AC system is running low on refrigerant, you need to top it off. Here’s how to get that done:
- Gather the Necessary Tools and Materials: To recharge your AC, you’ll need a recharge kit, safety glasses, and gloves. And make sure you pick up refrigerant that plays nice with your system.
- Locate the Low-Pressure Service Port: Check your owner’s manual or a repair guide to find the low-pressure service port. It’s usually somewhere near the firewall on the passenger side under the hood.
- Attach the Recharge Hose: Fasten the recharge hose from your kit to that low-pressure service port. Make sure it fits tight.
- Start the Engine and Turn on the AC: Fire up the engine and max out the AC to let the refrigerant flow right during the recharge.
- Add Refrigerant: Follow the directions in your recharge kit to add the right amount of refrigerant to your AC. Don’t go overboard, though – too much refrigerant can mess with the cooling, or worse, damage your AC system.
- Monitor the Gauge: Watch the gauges as you add the refrigerant to make sure they’re in the right range the manufacturer recommends. When you’ve got the right amount in there, cut the hose and call it done.
Recharging your AC will get the refrigerant levels back up and your AC working like a charm.
Driving Tips For Keeping Your AC Cold
To make sure your car’s AC keeps blowing cold air, follow these tips for regular upkeep:
- Keep the vents and air outlets shipshape by cleaning off any dust or junk.
- When possible, pick spots in the shade while parking. That way, you’ll have less heat stacking up in your car.
- Window tinting lowers the amount of heat entering your car’s interior and helps the cabin stay cooler.
- When driving, maintain a consistent speed. Abrupt speed changes can put stress on the air conditioning system.
- Get help from a good mechanic to check for leaks, do repairs, and top up the system when needed.
