5 Signs Your Car’s Air Conditioning Needs Repair
On hot days, your car’s air conditioning system is one of the most important features of your vehicle. However, it’s also a system that is prone to the wear and tear that inevitably comes with frequent usage. If your car’s air con fails on a hot day, it can turn a comfortable drive into a sweaty nightmare.
To prevent untimely air con failures, it’s important to have your vehicle regularly checked, serviced, and repaired as necessary. Knowing when your vehicle is in need of a car air con service can be challenging, but there are ways to determine you’re due for an aircon regas. Here are four of the most common signs of a damaged air conditioning system that let you know you should book an appointment with a qualified mechanic.
One of the most obvious signs of an air conditioning system in need of a service is weak airflow from the cabin vents. This weak airflow may mean the air is having trouble reaching your air vents. This is often caused by a buildup of mould or mildew in the evaporator core, or a broken ventilation fan. However, it can also be caused by other issues such as an opened core case seal, house seal, or evaporator core case seal, as well as a loose blower house – all of which can make the car aircon blower weak.
There are several different issues that can impact the amount of air reaching the cabin of your car. If you regularly notice a weak airflow, it’s important to get your air conditioning checked by an expert who can properly diagnose and fix the problem before it becomes a larger issue.
Car Air Con Noise
If you’re constantly hearing a strange rattling noise when you turn your car’s air conditioning on, or if you hear the car aircon making hissing noise, it’s likely there is an issue with a component within the system. It’s impossible to know exactly what is causing the rattles in your air vents without getting the air conditioner serviced by a qualified mechanic. A rattling noise is often a sign of a broken fan belt or condenser. However, it could also be a result of debris or a crucial component has come loose. If you do hear an unusual noise, it’s best to get it checked as soon as possible as it can indicate a more serious issue.
If your air conditioning smells like sweaty clothes, this can be a sign that your cabin air filter is damaged. This filter should be regularly cleaned, or replaced as necessary, to prevent long-term damage to the air conditioning system. By properly maintaining the cabin air filter, you’ll not only keep the air inside your car clean and fresh, but you’ll also save money by reducing fuel consumption.
Another common cause of unpleasant odours is a mouldy evaporator case or air vent. This is particularly concerning, since some people are allergic to moulds. To prevent this problem, it’s important to regularly have your car’s evaporator case and air vent cleaned. You should pay attention to any strange odours in your car, since certain smells can indicate problems that require immediate attention in order to keep you safe on the roads.
Only Warm Air
Sometimes when your air conditioning system isn’t functioning, the vents initially blow cold air that turns warm over time. This can be caused by a number of underlying issues, including a clogged expansion valve that restricts flow from the refrigerant into the evaporator. It can also indicate a damaged compressor, or a blown fuse – all of which are problems you should get checked right away. When your air con blows hot air, a straightforward repair by a mechanic can restore the system to its full efficiency. This means a more comfortable and safer driving experience for you and your passengers during those hot summer months.
