Everything to Know About Car Air Conditioning Repair

Not to be confused with the deadly plague in the 14th century, a car experiencing Black Death can spread very fast just like its namesake. When the refrigerant, which acts as a working fluid, breaks down, it results in ugly wear and tears in the compressor. This kicks off the Black Death inside the compressor, leading to the creation of sharp and grimy metal particles. They travel through the rest of the A/C system, wreaking havoc everywhere. Before you can comprehend what is happening, airflow and cold air are long gone.

The best way to protect your Air Conditioning Aldershot from Black Death is a frequent performance check.

CAUSES OF WEAK AIRFLOW IN YOUR A/C

Weak airflow causes pain and discomfort. If you can detect reduced airflow early, immediately have it checked to avoid any unnecessary harassment later. A few reasons for weak airflow is given as follows–

  • The evaporator core may have an accumulation of mildew or mould from residual moisture occurring during the cooling process. This obstructs the air from reaching the air vents.
  • Weak airflow can also be caused by a loose hose. The hose in question is usually the blower hose that is used for supplying air to the blower unit.
  • If the ventilation fan is fried, it won’t blow which leads to diminishing of airflow.
  • Blower house seals, evaporator seals, or core case seals may open up, reducing airflow. The ventilation system of an A/C is very sensitive should always remain sealed. The whole system is compromised if they are opened.

CAN I BE ALERTED WHEN THERE IS AN A/C PROBLEM?

Usually, there are no system warning lights to warn you if your ac is not working properly. But, Driver Information Centres (DIC), which might display a vehicle systems’ status, are equipped for some vehicles. You can get more information from the Owner’s Manual.

WHY YOUR AC IS NOT AS COLD AS IT ONCE WAS

There can be numerous reasons behind this. You should immediately bring your car for a check-up when it happens as it can make the difference between needing a small or a large repair.

The lack of cold air can be due to –

  • A failed o-ring, hose, seal, or component causing a Freon leak.
  • Clogging in the refrigerant charging hose or expansion tube.
  • A breakdown in the compressor clutch or compressor.
  • A failure or damage in the condenser or evaporator.
  • Leaks in vacuum
  • A malfunction in the blower motor resistor or blower motor.
  • A malfunction in switch, control module, fuse, solenoid, bend door or, relay.

An open system means when your ac system has a leak. Leaks can be very concerning. Early detection of leaks will make repairs less costly. If the cold air has been affected by a leak for a while, there is a high possibility that moisture has entered the AC system, damaging vital parts.

WHY IS MY AC STARTING OUT AS COOL AND THEN GETTING WARM?

As has been the case till now, there is no one reason causing this. You should bring your car for inspection if any of the following symptoms happen –

  • An adequate amount of refrigerant is distributed by the expansion valve to the evaporator. The clogging of the valve restricts the flow of refrigerant into the evaporator. In the presence of moisture, the refrigerant will freeze the valve altogether.
  • The compressor is unable to maintain proper pressure if it is not being engaged by the clutch. This will result in hot airflow.
  • It is fairly common for fuses to short circuit. If the fuse connected to the AC system blows, certain parts won’t have power.
  • Leaks occur when there is damage or moisture. A mixture of refrigerant and moisture results in the formation of corrosive acids which eat away at the components and seals.

WHY AM I GETTING PUTRID SMELLS FROM THE AC VENTS?

If you have an old and dirty cabin filter or if the evaporator case is mouldy, you will get nasty, gym locker scents from the AC vents.

HOW TO DETECT LEAKS IN AN A/C SYSTEM

Dyes enabled with blacklight – most refrigerants have a special UV dye already mixed in them that is visible under black light. Running a black light for detection of the dye is one way to determine if there is a leak.

A “sniffer”, which is a device that can hone in on the chemical components of the refrigerant, can also be used for detecting leaks.

In conclusion, what makes your A/C leak is moisture and age. The presence of moisture can also cause damage to the accumulator, receiver, or drier. These systems are used to remove moisture from the A/C system and stops working when there is a leak.
