What causes car air conditioner to not cool?
Auto air conditioning is as complex as the air conditioning in your home. This means that when some component goes wrong, the system can stop blowing cool air and can even break down altogether. Here are some of what causes car air conditioner to not cool.
- Low Refrigerant: Refrigerant is a chemical that helps pull heat from the air in an AC system. If it’s leaking or if its level is too low, it can’t perform this job. As a result, your air conditioner blows warm air. Low refrigerant is a common problem when it comes to auto air conditioning and needs to be seen to by a professional.
- Broken AC Fans: When your car's air conditioner fans are broken, they can’t blow cooled air around your car. This can happen even if there’s nothing wrong with your refrigerant levels. One thing to consider is that sometimes AC fans stop working for what seems to be no reason. There’s nothing wrong with the fan, but the problem may be with other components, the electrical system, or the blower motor. An auto mechanic can diagnose the problem.
- Dirty Filter: Like your HVAC filter at home, the cabin filter in your car traps contaminants such as dust and pollen. If it’s not cleaned or changed regularly, the dirt and debris accumulate and clog the filter. This can stress your car’s air conditioning system and even cause it to overheat.
- Faulty AC Compressor: An air conditioner's compressor allows refrigerant to circulate around the system and pull heat from the air. As with your home AC, if the car’s AC compressor fails, the air conditioning stops blowing cool air. You may also suspect problems with the compressor if you hear weird noises coming from your car’s engine along with the AC blowing warm air.
