Why is My AC Not Working?

This time of the year your air conditioning working may not be the first thing on your mind unless you live in the most southern parts of the country.  In reality the winter months can really be the most important time of the year for the air conditioning system in your vehicle to be functioning properly.  In winter months the extreme temperature swings combined with a lot of precipitation and frost in the mornings can make keeping your windows fog and frost free extremely difficult.  The moisture on your windows is removed by blowing warm, dry air over the surface to help the moisture evaporate.  The air in your cabin can be warmed up through the heater, but it can be difficult to keep dry during the winter months when there is so much moisture in your vehicle.  The air conditioning system is used to dry out the air in your car and make the defogging and defrosting process much more efficient.

How can I tell if my AC’s not working?

In the winter, it often can be difficult to tell if your air conditioning is working properly.  On many vehicles the AC light will simply not come on when you push the button if the air conditioning is not working properly, but you can also tell a few other ways.  You can check the AC compressor for operation by watching the center of the pulley while the AC button is pressed.  If the center starts to spin when the button is pressed you know the compressor is operating.  Lastly, you can hook up your air condition system to some gauges to test the pressures inside the system to see if it’s working properly.  Many auto parts stores sell replacement refrigerant that comes with a pressure gauge for the low pressure side if your AC system which can be an inexpensive way to test pressures.

Why is my AC not working?

The main cause of your AC not working is likely due to it having low refrigerant.  Your air condition system uses high pressure refrigerant to cool and dry the air in the cabin of your vehicle.  Due to the way the air conditioning system is designed and mounted in your vehicle, this high pressure refrigerant can leak out of a lot of different areas including the hoses, the fittings or the condenser and evaporator.  Even small leaks over the course of a summer of driving can lead to a loss of cooling power in your air conditioning system which can leave your windows foggy and difficult to keep clear.  This can lead to dangerous driving conditions especially at night with the glare of other driver’s head lights.

How do I fix my car’s AC?

To get your air conditioning back to its optimal operating condition you need to first seal the leaks and then refill it with refrigerant.  Tracking down your AC leak can be extremely difficult because the refrigerant used is an odorless colorless gas that doesn’t leave any traces as it leaks it.  It can be much easier to simply seal the leaks in your AC system from the inside.  BlueDevil Red Angel A/C Stop Leak can seal any leaks in your air conditioning system without the removal or replacement of any components.  BlueDevil Red Angel A/C Stop Leak will stay in your air condition system without harming any of the components.  Once it reaches the leak point, BlueDevil Red Angel will form a chemical weld caused by the temperature differential at the leak point, quickly sealing your AC Leak.
