Why does Car aircon servicing required?
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. Car aircon servicing ventilation systems are very sensitive and must remain sealed. Once they’re opened, the whole system is compromised.
Well, like many complicated stories, there’s never one simple answer. Car aircon servicing systems are a fickle breed. Your best bet is to have us inspect your system for any of the following listed symptoms.
From cold to hot and all the symptoms in between:
- The clogged expansion valve: The expansion valve distributes the proper amount of refrigerant to your evaporator. If the valve is blocked, the refrigerant can’t flow into the evaporator. With the valve clogged, the refrigerant will start to freeze the valve altogether if moisture is present.
- Faulty compressor clutch: If the clutch is not engaging with your compressor, than your compressor can’t maintain the correct pressure. Hot air will result.
- The blown fuse scenario: Fuses sometimes short out. If the fuse associated with your A/C system goes, the power to certain parts will stop.
Leaks are an Car aircon servicing system’s worst friend: Leaks are the result of damage or the presence of moisture. When moisture and refrigerant mix, nasty corrosive acids will eat away at seals and components, causing a leak.
