When the summer months begin, you will want a perfectly working air conditioning system in your car to keep you and your passengers cool while you travel. If you haven’t used your air conditioner for a while and you notice certain problems with it, take these steps to troubleshoot your car’s air conditioning system.
- Check the air coming from the vents. Use your hands to feel the air coming from air conditioning vents and see if it feels warmer than it usually is. Feel if there are any changes to the air pressure. Do this when the car is parked and idling because when the car is running on the road or freeway there will be added pressure and if you are low on Freon or pressure you won’t be able to tell the difference. Make sure nothing is blocking the vents and the tubes, affecting the quality of air coming through. If the air feels warmer, then one of the reasons could be that you are low on Freon. If you know how to add more Freon to the air conditioning system then turn off the engine and starting adding it. You can take your car to a repair shop and have a qualified air conditioner technician check and repair the Freon levels. If the air still doesn’t feel right after adding Freon, then its time to check for other factors. Check the compressor to see if it is functioning and see if there is slack on the belt. If the belt feels loose then replace it with a new one. Check again to see if everything feels right inside the vehicle.
- Check for odor. If you start noticing odor whenever you turn your air conditioning on, then you may have a problem with molds or bacteria. The mold and bacteria can grow inside your air conditioning system and thrive because of the dark and damp conditions. They can grow on the evaporator causing the air conditioning inside your car to smell like old socks. You have to flush out the mold or bacteria because constant inhaling of the odor can cause serious health problems. Look for chemicals that you can spray into the air intake and on the evaporator to get rid of the mold or bacteria growth.
- Check the cooling fans. The cooling fans on your car may be faulty so you need to check if they are working perfectly. When your engine overheats it can contribute to problems you are having with the air conditioning system. There will be a fan for the radiator and another one for your compressor. If one of the fans is faulty find a replacement and install it right away.
If you start noticing changes in your air conditioning system’s performance, have it checked by professionals immediately because prolonging a problem will cause greater problems in the future.
