The air conditioning system is now a standard feature in most car manufacturing. However, when you take your car for a routine repair or checkup, your priority is usually the engine and other essential aspects of the car consequently, car owners often overlook developing issues that can have negative impact their car air conditioner and wind up paying heavy fees to get the AC fixed or changed
Most of the things that create a failed air conditioner develop over time, so it’s not common to see sudden issues. However, if you’re currently noticing a more overt issue such as loud or unexpected noises coming from your vehicles AC, take it to a technician as soon as possible.
Else, these are some commonly overlooked vehicle air conditioning issues to look out for, as addressing these problems in a timely manner can you from more costly repairs down the line.
An air conditioner reduces the inside temperature of your vehicle. It also cools, dries, and cleans the air by forcing the warmer air to release outside. If moisture or debris comes to contaminate the air conditioner installed in the car, it will not work to cool the surroundings.
2. PUNGENT ODORS
Bacteria, fungi, and micro-organisms can startup when the air conditioning system is not being used, especially during winter. The dark and damp interior of your vehicle’s AC is the perfect breeding ground for them, and they often make themselves visible in the form of pungent odors.
These germs speedily grow behind the dashboard if left untreated and significantly add to “sick car syndrome.” A good inspection and flushing of your system can be done by a technician to stop this problem if it’s caught early enough.
3. REDUCED REFRIGERATION LEVEL
The refrigerant is to your vehicle’s AC what motor oil is to the engine, and simply by virtue of being present in the car, refrigerant levels in your car’s air conditioning reduce by 15-percent annually. Ironically, it’s during the winter and not the hot summer that this loss seems to be greater. When the unit is not in use, seals can dry out and impact the productivity of the unit ,makming it to go through refrigerant quicker.
Low refrigeration level can be corrected by re-filling the gas in the refrigerant tanks or fixing any visible leakage.
4. SOILED CONDENSER
The condenser is saddled with the responsibility of cooling the high-pressure refrigerant vapors exiting the compressor. Blockage of the condenser caused by the presence of dirt, grime, or debris will constrict the air flow so that no cooling will happen.
A clogged condenser can be rectified by employing a good quality flushing agent that vaporizes quickly and does not let residue in the system. Change the condenser if it has been used for many years and has given you issues in the past. If the rest of your AC is in good condition, the lower cost of changing this one part should far outweigh the headache of having to replace the entire system down the line.
5. MECHANICAL COMPLICATIONS
A compressor malfunction, bad compressor clutch, defunct pressure switch, or non-working valve will result in poor cooling or no cooling at all.
Because so many little parts are potential repairs waiting to happen, just carry out routine checks so that when something does crop up, you can tackle the issue immediately.
Switch on the air conditioning unit and check if the compressor, compressor clutch switch, fuses, wires, fan belt, and compressor seal are working adequately. Check whether the oil in the compressor has been spoilt. Flush the AC unit to change the old oil with new oil.
Tip: Regularly change the expansion valve, accumulators, and receiver driers. These parts are the most vulnerable to wear and tear and eventual failure. If they seem to be deteriorating or if they are suspect and it has been a while since the last change, it’s better to be safe than sorry.
