Auto Air Conditioning Repair Basics: Common Symptoms & Problems

by Marjorie, Cars for Keeps Social Media Manager

A broken air conditioner in your automobile gets put at the bottom of the "to-do" list all winter long. As we move into another warm, humid Michigan summer, however, suddenly having a car air conditioner that works - and works WELL - is of the utmost importance. Who wants to arrive at a meeting, the mall, or a friend's house sweating and flushed by stale, hot car air?

Having an auto air conditioner that "kind of" works may get YOU by, but faulty air conditioners can cause bigger damage to your car down the road if left unattended. An air conditioner running low on coolant, on dirty coolant on faulty electrical wiring can end up ruining the entire air conditioning compressor. Car air conditioners 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.

Generallly, auto air conditioners are fast, easy and inexpensive to fix. Most car air conditioning problems are coolant-related, and may often be as simple as getting a coolant flush, refill or fixed leak.

With that said, your car's air conditioners is not one of those devices most technicians recommend fixing at home, 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 atmoshere" 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.

Here are a few of the problems most commonly found in auto air conditioners:

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 150,000 miles or more, it's probably time.

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.

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.

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.

5)
Bacteria Buildup. Funky smells emanating from your car's air conditioning vents are likely caused by a bacteria buildup in the evaporator. Good auto mechanics (like Cars for Keeps!) will have the proper tools to flush the evaporator out quickly and without much cost.

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 (duh)
- 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 funky
- If the car has a tendency to overhead
- If the air filter or dryer have never been replaced, or if the AC has never been serviced before

If one of these symptoms applies to your car's air conditioning system, it's probably time to have it inspected by a mechanic. Caught early, most auto air conditioning problems are fairly easy and inexpensive to fix.

Stay cool!

It is true that you can fix your car air conditioning unit on your own, but it is better if you leave that kind of job to the professionals just like those in the auto repair in Indianapolis which I go to every time I have my car checked.

Just a friendly advice, if by any chance you visit Indiana, the car repair (Indianapolis, IN) I mentioned can do wonders for your car.

Ac repair said...

sensible Ac Maintenance advice, prevention is always better than cure so my advice is to ensure regular maintenance especially before summer arrives. This should avoid unexpected repair bills due to breakdowns.

Ashlyn said...

Having a car without air conditioner is a big prestige issue among society people. Not only that even faulty air conditioner can cause damage to your car, it’s better to solve out using instructions of your own if it is a minor problem rather than waiting for a Car Mechanic.

NYC Air Conditioning & Vent Cleaning said...

I am facing such a problem with my car AC, when I turn on my A/C, there is a strong vibration coming from the A/C compressor or it takes about 1-2 minutes & the compressor gets almost too hot to touch. The lines coming from the compressor are cold & the truck cools off just fine. I don't have a clue what could be wrong. I am currently not running the A/C for fear of tearing it up.

Ayesha Tariq said...

Hi, I follow your blog for a long time and must tell you that your posts always prove to be of a high value and quality for readers. Keep it up.

Bennie said...

I agree that it would be best to have the AC problem fixed at an early stage. There are signs that can give the owner an idea that there is something wrong with his AC. I really liked the discussion that you gave about the possible causes of such problems.

I regularly have our air conditioning (Cary and other places)checked by professionals. It is most recommended to have experts in (Cary) HVAC check the device bi-annually. That way, the device would be sturdy and well functioning.

Very informative. Thanks!

HyunChard said...

I really don't understand this Split System thing in airconditioning, would someone don't mind explaining it here?

Mike's Vent Cleaning said...

Thanks for the tips to repair.It is very important to maintain the air conditioners to get the best service from them and also look after the environment by not polluting the clean air around.

Air blower system said...

The most likely cause of an automotive air conditioner cooling problem is no refrigerant in the system. One of the first things you should check, therefore, is compressor engagement. If the compressors magnetic clutch is not engaging when the A/C is turned on, the problem may be a blown fuse or a wiring problem. If the fuse is blown, replacing it may restore cooling temporarily. But the underlying reason for the fuse blowing in the first place needs to be identified and corrected to prevent the same thing from happening again.

precision said...

Checking your HVAC for maintenance is very important specially every summer. This will help us keeping our home in a comfortable temperature......Better prevention is always necessary to the electronic goods....

Mike's Air Conditioning said...

It is surely very important to know the basics of repairing a system when there is a break down.The air conditioners have to be serviced and maintained for better performance.

Peter said...

Take it from someone who knows. It gets hot in the south, especially in Virgina, and reliable air condition repair is a must. No one wants to get all sweaty or suffer from heat stroke. Don’t wait too long to keep cool.

Make sure there is gas in the lawn mower. If you have old gas in the lawnmower and did not put in a fuel stabilizer at the end of the season, replace the gas. If you had drained the gas tank at the end of the previous season, then fill the tank at least half full with new gas.Gas Ducted Heating Repairs

My question is somewhat advanced. I have a 1994 Buick Roadmaster with auto climate control. I have a gauge set, a leak detector, and a vacuum pump. Anyway, gauge set results are Low Side 40/20, High Side 130, Outlet air temp 57, Outside Temp 74, Outside humidity 45%. New Compressor was installed 4 years ago, but could it be going already? No odd noises.

Bailey Lovett said...

It is very interesting and useful post you have shared. How often should the A/C system be Inspected/Service? Can you give me information?

Nicole Vickers said...

When our car AC malfunctioned, we had it fixed immediately. I agree that bacteria build-up is one of the most common causes of air conditioning failure. The tips you shared can be very helpful for those who're having a hard time fixing their car ACs.

Sebastian Gaydos said...

A faulty air conditioning is hazardous for the driver and passengers of a car. For me, a "kind of works" kind of AC is more energy-consuming than a non-working one. That's because such a system releases dangerous CFCs into the atmosphere (especially if it's an old model).

Sky Bird said...

Hi there. Nice blog. You have shared useful information. Keep up the good work! This blog is really interesting and gives good details. AC Stabilizers, AC wall mounted voltage stabilizer.

Kam said...

Does the time when you need to be re-filling your ac depend on the amount of usage or the age of the vehicle, i.e. if your car is in a colder climate not used so much will it last longer or does the coolant deteriorate just as quick?

able appliance said...

Yeah you are absolutely right about your point of view it. I agree with you and your point of viewing this stuff as this is very similar to my point of view. As you know how the accounts are been considered in a successful companies. One mistake cans blond thousands and millions of dollars which put a very bad impact on the economy of the state.

A lot of people really like to fix their own vehicles, but sometimes, repairing your air conditioning unit’s parts or components can be complicated. That’s why if you think you can’t handle it on your own, it would be better that you ask for the help of a qualified and certified mechanic. Fixing it yourself, without having the right skills, may make it even worse. So to save you a lot of time and money, find a mechanic that you can rely on and can do the job right away.
