What are the 6 signs that your auto air conditioning may need repairing

In hot Sydney, one of the worst things that can happen to your automobile is the breakdown of its air conditioning. To avoid a completely non-functioning air conditioning, there are some signs that you may be able to pick up on. If you catch your air conditioning before it fully breaks down then you’ll be able to repair it and prevent an uncomfortable ride in your vehicle.

Why does an automobile’s air conditioning need to be repaired?

A variety of reasons can contribute to the malfunctioning of your air conditioning system. It can range from improper operation, wear and tear or manufacturing issues. Here are some of the most common reasons.

●     Leaking or depleted refrigerant – Refrigerants absorb heat and convert it into cool air. This process is responsible for your car feeling cool, so if it malfunctions, then you’ll begin to feel warm.

●     Coil and condenser failure – The condenser cools the highly pressurised refrigerant vapours coming from the compressor. It can become blocked and overheat.

●     Faulty fan – The fan is responsible for circulating the air through the coils, if it fails, the airflow will remain warm.

●     Frozen or broken evaporator – A faulty evaporator causes your car’s system to switch between cold and hot air.

●     Poor expansion valve and orifice tube – These tubes can freeze, causing icy air to flow through your system.

Now, that you understand what can cause a car to malfunction, let’s discuss 6 common signs that your air conditioning may need repairing.

Warm air conditioning

This is an obvious sign but, if your air conditioning suddenly starts circulating warm air, then you definitely have an issue. Before you visit a repair service, first ensure that your heat is not turned on and that your cool air is—this is just to avoid an unnecessary trip to an auto electrician. If you do have a warm airflow then it may be due to lack of refrigerant, a clogged expansion tube, broken compressor or blower motor or a failed fuse or switch.

Poor airflow

If you’re experiencing a weaker than usual airflow then it may be that something is blocking the air from coming out of your vents. Ensure that your air conditioning is turned on high in order to make certain that airflow is indeed weak. Poor airflow may be due to: accumulated mould or mildew in the evaporator core, loose blower hose, overheated ventilation fan, or opened case seals.

Leaking dashboard

If your mats are cold and damp or water-stained, then check your dashboard. If it’s leaking then it may be a sign that your air conditioning is about to malfunction. The water comes from a clogged hose which prevents water from sipping out. If your system is old, this can be a sign to look out for. Ensure that you get this repaired immediately. Water in your air conditioning system can cause further damage to your system and car, causing you more money.

Unusual noise

Whenever you hear your air conditioning system making noise, don’t think that it will pass. It can be a sign of a larger problem. A rattling noise may be an indication that you have either a broken condenser or fan belt or debris in either. Carry it immediately to your air conditioning repair service provider to ensure that the problem is sorted.

Unusual odours

If you notice that the air coming from your air conditioning smells like damp or sweaty clothes then it may be that your system’s cabin air filter is dirty or old and worn. If it’s dirty, you’ll need to get it cleaned but if it’s dirty and worn, you’ll need to get a replacement. Leaving your air filters in your car without regular cleaning or replacing then can lead to increased fuel consumption and a strain on your auto air conditioning system. If it is not your air filter, then another possible cause may be a mouldy evaporator case or air vent.

A burning odour may indicate that your compressor is burnt or overheated, preventing your system from working properly. You’ll need to immediately repair the wirings of your compressor.

Inconsistent air temperature

If your air conditioning is working fine and then suddenly goes warm, then cool again and keeps waffling back and forth then it may be that your evaporator is either frozen, blocked or broken. Don’t think that the air conditioning will fix itself, this problem won’t go away unless you head to your nearest repair shop to fix the evaporator. Another cause can be a damaged compressor clutch, a blown fuse or leakage.
