Symptoms and Common Problems of an Automotive Air Conditioning System

In Florida, A broken automotive air conditioning system can be almost as bad as not having a car in the first place. Yet another hot, humid Florida summer is suddenly upon us and we can’t put off automotive air conditioning system problems another day.  Suddenly having an automotive air conditioning system that works, and works well, is of the utmost importance to your very existence. It is almost imposable to arrive at a meeting, the mall, or a friend’s house sweating and flushed by stale, hot car air, and in Central Florida, downright unhealthy!

Having an automotive air conditioner system that works only part way may get by in a northern city with 3 months of hot weather, but faulty air conditioners can cause bigger damage to your car down the road if left unattended in an area with a full 8 months of truly hot weather.

An air conditioner running low on Freon, on dirty coolant or on faulty electrical wiring can end up ruining the entire air conditioning compressor (much more expensive than a simple recharge or flush). An automotive air conditioning systems are connected to the rest of the vehicle’s electrical system, meaning a surge or problem with the air conditioner can cause problems with the rest of the car, causing poor idling, fuel inefficiencies or drained batteries, or much worse – prematurely spent alternator and serpentine belt.

Generally, automotive air conditioning systems are fast, easy and inexpensive to repair if handled correctly with the right equipment or by a professional with the same. Most automotive air conditioning system problems are coolant-related, and may often be as simple as getting a coolant flush, refill or fixed leak. Do not be fooled by the “you can fix the leak yourself” cans available at your local Wal-Mart and Big Lots, you will more than likely destroy your compressor, do not use these products!

With that said, your automotive air conditioning system is not one of those devices most technicians recommend fixing at home anyway, unless you’re a qualified mechanic. Most do-it-yourself instructions for fixing broken auto air conditioners contain scary phrases, like “it is illegal to release Freon gas into the atmosphere” and “be sure to wear proper hand and eye protection”. Plus, there are many different things that could be wrong with the car’s air conditioning system, which if handled by a professional could be a simple fix, yet handled wrong could turn into a repair costing literally thousands.

Pop’s Auto Electric and AC has compiled a list of most often found problems associated with automotive air conditioning systems:

1) Coolant and/or Refrigerant Leaks:

This generally applies to older, less computerized vehicles. Refrigerant can run out on its own over the course of time, or leaks may have developed in the car’s AC compressor or one of its hoses. If your vehicle has never had a coolant flush or refill and it’s pushing 75,000 miles or more, you need a coolant flush and ac tune up.

2) Noisy AC Compressor:

Noises that occur when your car’s AC is turned on can come from minor engine noises or hoses, but they could also be symptoms of problems with the compressor. If the problem is the AC compressor, it will likely have to be replaced.  If you do not have the noise looked at and it turns out to be a faulty compressor, what could have been just a compressor replacement, can turn into a whole system replacement as pieces of the disintegrating compressor are spread throughout the entire automotive air conditioning system, if it is to completely come apart.

3) Fluctuating Temperatures:

When a car’s AC blows out air with sporadic temperatures, it’s often likely that moisture is building up in one of the hoses or assemblies, causing ice to accumulate and clog. Removing ice from a car’s air conditioning assembly is a short and easy procedure.  Delaying this repair, can damage the dryer, compressor and lead to much higher repair cost.

4) Faulty Car Electrical System:

A weak car battery can cause your auto air conditioner to function weakly or not at all. Car batteries need to have enough voltage to trigger the AC compressor, and while it may be strong enough to run the rest of your car, it may still be too weak to run your car’s air conditioning.  Electric is one of Pop’s Auto Electric & AC’s particular specialties, no problem with this one!

5) Bacteria Buildup:

Funky smells emanating from your automotive air conditioning system vents are likely caused by a bacteria buildup in the evaporator. Pops Auto Electric & AC will have the proper tools to flush the evaporator out quickly and without much cost.  Your car will smell clean and fresh again without that pine sent thing, we like to make you smile!

So what are some basic ways to tell if any of these are a problem for your car’s air conditioning unit? Here’s a basic checklist of symptoms which indicate something is wrong with your auto AC:

• If the AC system doesn’t produce cold air

• If the fan or blower doesn’t work

• If the fan, blower or AC is noisy when turned on

• If one of the dashboard controls malfunctions

• If the vent, car heater or defroster are having problems working correctly

• If the air conditioning smells funny

• If the car has a tendency to overheat

• If the air filter or dryer have not been replaced, or if the AC has never been serviced and the car is over 75,000 miles old

Caught early, most auto air conditioning problems are fairly easy and inexpensive to fix.
