When the weather gets hot and humid this summer in Florida, you’re going to want to be able to crank up your air conditioning and cool off when you get into your vehicle. There are few things worse than getting into a stifling hot car on a sticky Florida day in July and suddenly realizing your air conditioning isn’t working.

Therefore, it’s important to conduct a thorough overview of your vehicle’s air conditioning system before the summer hits so you know it’ll be in good shape all summer long. By performing preventative maintenance and analyzing the system before the summer starts up, you’ll be able to pinpoint small potential issues before they turn into big, expensive ones.

Here are just a few examples of some of the most common problems that necessitate auto AC repair in Port Charlotte, FL:

  • Lack of refrigerant: This is the most common cause of air conditioners not providing cool air to a vehicle cabin—a simple absence of refrigerant in the system. This may be a result of a leak in the condenser or evaporator, or in a hose. Finding the leak and repairing it must be done before you fill the refrigerant back up. Of course, the issue may just be that you needed to put more refrigerant into your vehicle. This is the first solution you should try, unless you notice signs of leaks, such as pooling under your vehicle.
  • Poor cooling: One way you can see if there’s a problem with your air conditioner is to use a gauge to set the high and low pressure AC service fittings on your system. Check the low pressure readings with the engine off. On an 80-degree day, this gauge should read 56psi if it is working properly—any lower and you may need to charge your refrigerant. There may be other factors causing lackluster cooling, such as overcharged refrigerant, a buildup of moisture inside the cooling systems, plugged tubes or hoses and compressor or valve failure.
  • Intermittent cooling: Your AC system may blow cold air into the vehicle for a little while, then suddenly stop or turn warm. This could be a problem with the system freezing up. The combination of air and built-up moisture in the system may result in ice forming, which can block off the orifice tube. You can use a vacuum pump to get rid of moisture and air in the system.
  • Strange odors: Do you notice weird smells emanating from the system when you use it? This means you’re probably dealing with microbes or mold. Dark, damp places are breeding grounds for mold and mildew, so it’s important you get this issue resolved as soon as you start to notice the smell so the problem doesn’t get worse and it doesn’t end up affecting your health.
