Jumping into your car after a sunny spring day can be an unwelcome surprise. The windows and cabin of your vehicle act a lot like a greenhouse when it’s left in direct sunlight. The sun’s energy can enter through your windows or be absorbed by the metal roof but has no way to escape. This heat is trapped and can cause the interior of your vehicle to get extremely hot on sunny days. You can help mitigate this effect by tinting your windows, choosing a light color paint or using a windshield sunshade but those are not solutions, they just lessen the problem.
The great thing is we live in a country with air conditioning almost everywhere. Let’s be honest, when a soft top jeep has air conditioning as an option, we’re a country that likes to be comfortable. So you jump into your hot car, throw on the AC and you get hot air blowing. Not to worry, it takes a few seconds for the air conditioning system to come up to pressure and start cooling your cabin air. Now you’ve waited 15 seconds.. now 30.. now 2 minutes and you’re still getting nothing but hot air.
So now that you are sweating, and frustrated it can be tempting to zip into the dealership and pay them whatever they ask to fix your air conditioning. This is an option, but before you break the bank, head home and let’s take a look at some common easy to fix problems that would make you ask: Why is my car AC blowing hot air?
Common Easy to Fix Air Conditioning Problems:
- Blocked Condenser
- Broken Condenser
- Low refrigerant
- Broken cooling fans
The condenser in your air condition system looks a lot like a radiator and is mounted at the front of your vehicle. It is used to cool the hot compressed refrigerant back to ambient temperature as it comes from your compressor and uses the air your car is traveling through to do that. If this isn’t accomplished, the still warm refrigerant will travel through the expansion valve and rather than getting comfortably cold, it is only cooled back down to ambient temperature and will cause your AC to blow hot. Since the condenser is at the front of your vehicle, it has the opportunity to get clogged by all kinds of road debris from leaves to plastic bags or anything else you might stumble upon. A quick visual inspection and removal of these air blocking items may return your air conditioning to normal operation.
Since your condenser is at the front of your vehicle it is also subject to less kind road debris like rocks, sticks or other hard objects that may puncture it. If the puncture is large and easy to see, replacement is a must. Before you head back to the dealership, consider changing the condenser yourself. They often are mounted to your car’s frame with just a few bolts, only have 2 refrigerant lines which should be easy to remove, and are easily accessible since they are at the front of your vehicle. If you cannot see the puncture, consider adding UV dye to your air conditioning system to identify the puncture point, or simple add BlueDevil Red Angel Air Conditioning Stop Leak to your air conditioning system to quickly and permanently seal the leak.
Similarly, you may have a low refrigerant situation due to other causes like loose connections, old hoses or the simple escape of refrigerant over time. These small leaks can cause your air conditioning system to stop blowing cold air. Before you recharge your air conditioning system, add BlueDevil Red Angel A/C Stop Leak to ensure your system is properly sealed and will stay charged.
The last easy to fix problem you may have with your air condition system in your vehicle is a broken cooling fan. The condenser can only cool the refrigerant if it has air moving over it. If you are driving at low speeds or stopped in traffic or at a light, a fan can provide the adequate air flow to keep your air conditioning system working properly. Over time this cooling fan may become worn out and stop working. It also may blow a fuse or become clogged or blocked by debris. Be careful when checking around any fan as it may start at any time! Checking to make sure the cooling fan has power and is working properly will ensure your air conditioning system works under any driving conditions.
