Why Your Car May Be Blowing Hot Air

April 3, 2019 7:35 pm Published by Leave your thoughts

We’re approaching peak air conditioning season here in Florida, both in our homes and in our vehicles. There are few things more uncomfortable than getting into a steamy, oppressively hot vehicle that’s been sitting out in the Florida sun, only to find out that the air conditioning is only blowing hot air when you turn your vehicle on.

This isn’t just an issue of comfort—it’s also an issue of safety. The temperature can quickly rise to unsafe levels in a vehicle that’s sat outside for a while during the summer. Inside a car without air conditioning is one of the most dangerous places a person can be during a severe heat wave. For this reason, it’s important you get your vehicle checked out by a technician who can look at your auto air conditioning in Port Charlotte, FL.

Here are just a few of the most common issues that result in auto AC units blowing hot air:

  • Refrigerant leaks: Refrigerant leaks can occur in any part of the air conditioning system, and it can be difficult to find exactly where a leak is located. Sometimes you can see refrigerant oozing out of connections, or you may see refrigerant pooling underneath your vehicle where it’s been parked. Check your refrigerant levels, refill it if it’s low and if you keep running through refrigerant, then you know you’ve got a leak.
  • Condenser issues: The condenser in your vehicle’s AC unit is designed to re-cool hot refrigerant after it’s been compressed. If the condenser is blocked by debris, it will not be able to complete the cooling process properly. In addition, you may have an entirely broken condenser, which may be caused by a buildup of this debris getting into the vehicle and damaging the part. Simple equipment failure may also be a cause of your condenser issues. Whatever the case, it’s important to have the issue resolved.
  • Electrical problems: Electrical issues can be difficult to diagnose in a vehicle—you’ll need to check and see if any wires are broken. If you do find damaged wires, you can either attempt to mend them with electrical tape or completely replace them. If a visual analysis does not reveal any obviously damaged wires, you should have a certified technician check out your vehicle.
  • Compressor problems: The compressor is what keeps the air conditioner moving. When it doesn’t work properly, refrigerant will not flow through the system and you won’t get any cold air. Compressors may go bad due to long periods of inactivity. It can be a good idea to run your air conditioning system on full blast for a few minutes every few weeks or so, regardless of the temperature, just to give it some exercise.
  • Cooling fan problems: If fans aren’t working, your condenser might not receive cooled air, which can result in your car only blowing out hot air.
