The air conditioning system of your vehicle is an important feature that keeps the temperature inside your car comfortable. However, it is one of the things that get worn and damaged due to frequent usage and old age. When your vehicle’s air conditioning fails to provide the right temperature that you need, it’s important to have it checked, serviced, and repaired as necessary.
Here are signs that your auto’s A/C unit needs repair:
1. Weak Airflow
A weak airflow coming out of your car’s air conditioner means that the air is having trouble reaching your air vents. This can be caused by an accumulated mold or mildew in the evaporator core, loose blower hose, fried ventilation fan, or opened core case seals, blower house seals, or evaporator core case seals.
2. Leaking Dashboard
A visible water stain on your mat can be an indication that your dashboard is leaking. A leaking dashboard can be a sign that your hose is clogged, which prevents it from sipping the water out. Age and moisture may cause A/C system leaks. This can create further damage to other components so it needs to be fixed immediately.
3. Losing Its Cool
When you notice your vehicle’s air conditioning begins to lose its cool, it may be due to lack of refrigerant, a clogged expansion tube or refrigerant charging hose, broken compressor, broken blower motor, damaged condenser or evaporator, or a failed fuse or switch. This symptom may need a small maintenance or a major repair, depending on what’s causing it.
4. Leaking Refrigerant
The refrigerant is the one responsible for keeping the interior of your car cool. If you notice your air conditioning can no longer provide a cool temperature despite having turned it on for so long, there’s a chance that your refrigerant is leaking. Rubber seals and hoses can lose their elasticity over time, allowing the refrigerant to escape.
If moisture is present, it can cause damage to the accumulator, receiver, or drier. A leaking refrigerant needs immediate attention because it can affect and damage these other vital parts of your A/C.
5. A/C Starting Out Cool Then Suddenly Gets warm
There are many possible causes why your air conditioning system starts blowing out cold air but then suddenly gets warm after a while. It may be caused by a clogged expansion valve which blocks the refrigerant from flowing into the evaporator. This may also be a cause of a damaged compressor clutch that prevents the compressor to maintain the correct pressure. Or it may also be a sign of a blown fuse or leaks.
6. Unusual Noise
When you hear unusual, rattling noise whenever you turn your car’s A/C on, this may be a sign of a broken fan belt or condenser. There’s also a chance that the noise is caused by debris in the fan. Unusual noises should not be ignored because they can be a symptom of a more serious problem.
7. Nasty Odor Coming From the A/C
When you begin to notice nasty odor that smells like sweaty clothes, your A/C’s cabin air filter may be dirty or worn. You need to have this cleaned, or perhaps a replacement is necessary. Regular changing of air cabin filters will help prevent long-term damage to your air conditioning system, and it will also help reduce your fuel consumption.
10. Burning Odor
When you notice a burning odor when you turn your air conditioning on, chances are the wirings of your compressor are burnt or overheated. Damaged compressor wirings prevent the vehicle’s air conditioning system to function properly. You will need to repair or replace the wirings immediately to fix this issue.
