If you’re about to go to bed and want to avoid nightmares, you might want to put off reading this until morning. If you’re about to get in the car, please read on.
While Black Death is not the same as the deadly plague during the 14th century, a car A/C system experiencing Black Death will be infected like the plague. Black Death starts out inside the compressor after refrigerant breaks down. Since refrigerant acts as a working fluid much like how motor oil is the fluid which provides lubrication to protect the engine, a refrigerant breakdown will result in ugly wear, starting in the compressor. From there, the sharp and grimy metal particles created during compressor breakdown can then travel through the rest of your A/C system, wreaking havoc on the entire system. Before you know it, all cold air, and airflow for that matter, will be long gone. Cue the A/C grim reaper.
Why does my A/C have weak airflow?
We feel your pain and discomfort caused by weak airflow. The sweat alone is enough to drive any of us crazy. However, there are a lot of factors at play. If you notice reduced airflow early on –rather than later– take the right step and have it looked at before other fatal A/C system damage can occur.
Main causes of weak airflow:
- Mold or mildew may have accumulated in the evaporator core from residual moisture that occurs during the cooling process. When this happens, air will have trouble reaching your air vents.
- A hose has come loose. This usually happens with the blower hose that supplies air to the blower unit.
- Ventilation fan is fried. If the fan’s not blowing, air won’t be flowing very well.
- Seals. No, not those seals down by the pier. Core case seals, blower house seals or evaporator core case seals; All can open up and diminish air flow. A/C ventilation systems are very sensitive and must remain sealed. Once they’re opened, the whole system is compromised.
