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.
