4 Reasons Why Your Car’s Air Conditioner Might Be Blowing Hot Air

So, you got up this morning, drank your morning coffee, showered and got out the door – so far so good, right? It’s June and you noticed that today is a little muggier than usual. No problem! You’re only a few feet away from the sweet, sweet air-conditioned comfort of your car. You get in, buckle up, turn the key, and switch the A/C fan up to high. And in that very moment, you’ve realized your car has betrayed you and it’s blowing nothing but hot air. But why?

Cold Air Intake Tips for Performance

As a car lover, there’s nothing better than driving around with a beast under your hood. However, when it comes to improving engine performance, many modifications can be rather time consuming. A great way to give your ride a little extra kick, without making major alterations, is by using a cold air intake.

Why do I want a Cold Air Intake?

Warm air doesn’t expand as much when in the pistons. However, cold air does. So, by cooling the air you are allowing for maximum combustion and you know what that means .. More Power.

A cold air intake is installed on the intake side of the engine and theoretically increases horsepower by pulling dense, cold air into the engine. This is not going to be a dramatic increase in horsepower, like you would see by installing a high end supercharger. However, it is a low cost and easy to install device that will give a slight boost in performance of anywhere from 3 to 15 horsepower.

Another great benefit is that a cold air intake increases the amount of oxygen in the engine. With an abundance of air your engine does not have to work as hard while driving. This will result in better fuel consumption and less engine damage.

Cold Air Intake Precautions

When the intake is located near the bottom of the vehicle, you are at risk of sucking up water from puddles when driving in wet conditions. This water can possibly go straight to the engine and destroy it.

You should also make sure that the cold air intake has sufficient filtration. Car manufactures go to great efforts to make sure that excess dirt is prevented from entering the engine. If the cold air intake is not properly sealed from dirt and debris, the engines life expectancy could be shortened.

Beat the Heat with Air Conditioner Maintenance

Summer creeps ever closer—it’s still about a month away, officially speaking. Schools are letting out and the weather has taken a turn for the better. Finally. Temperatures have even inched into the 80s lately. Make sure your car’s air conditioner is ready to beat the summer heat.

No one likes to sit in traffic or commute to work in a stuffy car. It’s miserable. Addressing the problem can often be difficult for the average, non-car buff kind of person. Freon, a thing we’ve all heard of, is a compressed liquid and gas combination that circulates through the A/C system. But that’s not all that makes the air conditioning work. There are several other components that make up the system:

  • refrigerantcar-ac-vent
  • expansion valve
  • condenser
  • compressor
  • evaporator
  • receiver-drier

Any of these components could be loose, broken, clogged, or leaking. Should you simply need more Freon, you can easily fill that yourself. However, Freon isn’t always to blame for the problem.

When the Heat Hits

Most drivers notice their A/C not working while in idle traffic. Driving across town to pick up milk can be miserable in the middle of summer with no air flowing. This can be caused by overheating of the engine, low Freon, or a lack of decent air flow over the condenser. Typically, driving on the highway is much less of a problem because winds are strong and the engine is performing more rapidly, causing the coolant to circulate quicker as well.

One way to help keep cooling problems at bay is by running your air conditioning system on a regular basis. Even in winter, 10 minutes a month is recommended. The owner’s manual will have more details about how your particular heating and cooling system works. Be sure to take a look there before assuming the worst.

If the cooling, or lack of cooling depending on how you look at it, issue persists…it’s time for real help. Some repairs will take the use of special equipment, so check with your local auto repair shop for more information.
