Why Your Car's Air Conditioner Can Only Blow Cold Air for So Long

Last updated 7 years ago

Phoenix residents rely heavily on their vehicle’s air conditioner for a large portion of the year. With summer just around the corner, the last thing you want is to get into your sweltering hot car only to find out that the air conditioner isn’t working. Learn more about the importance of routine AC maintenance with an auto repair shop with this overview on why your car’s air conditioner can only blow cold air for so long.

Low Refrigerant Charge

One of the most common reasons that your air conditioner may stop blowing cold air is caused by an insufficient Freon charge. The amount of Freon in your condenser is extremely critical, as low levels can result in inadequate cooling under high heat loads. While some individuals choose to recharge the Freon themselves, overcharged fluid can actually damage your AC compressor even more. Don’t make the problem worse—have your refrigerant recharged with an automotive repair specialist.

Coolant Leaks

In some cases your air conditioner may stop blowing cold air due to a coolant leak. The most common areas for coolant leaks include:

  • In the evaporator towards the back of the engine.
  • Compressor.
  • Condenser coils.

You may know where these leaks generally occur, but that doesn’t necessarily mean that you understand what you’re looking at. Leave the hard work to the professionals and find the source of the leak with an auto body repair shop.

Dirty Condenser

Your vehicle’s condenser is responsible for cooling the high-pressure refrigerant vapors coming out of the compressor. Dirt and debris can often accumulate inside the condenser and evaporator coils, making your air conditioner work harder to cool the inside of your car. Be sure to have your condenser coils cleaned regularly to allow for sufficient air flow.

If your vehicle’s air conditioner is taking too long to cool, making noise, or isn’t producing cold air, then it’s time to see your auto repair company. For the best AC repair and towing services available visit one of our Greulich's Automotive Service & Collision centers today.
