Getting your car’s AC serviced regularly is essential if you live in a hot climate. Not only does this help to keep your car comfortable in summer weather, but it can also extend the life of your air conditioning unit. 

And if you’re unsure when your car’s air conditioner needs repairs, keep reading for tips to tell if it’s broken.

Air Conditioning and Your Car

AC isn’t just for summertime – it can help keep you comfortable all year round. But like any mechanical device, your car’s AC system can wear out over time and need to be serviced.

Here’s what to look for when servicing your AC system:

-Check the compressor for damage or malfunction. If the compressor is damaged, it may not be able to cool the air properly, which could lead to a host of problems, including overheating and premature wear on your car’s other mechanical components.

-Test the cooling system by running the car without the AC on. If the fans don’t kick in and the interior temperature reaches 85 degrees Fahrenheit or higher, there may be a problem with the cooling system.

-Check for leaks – water leaking from anywhere in the system will cause overheating. Look for signs of water damage, such as rust or swelling around hoses and fittings. If you find any leaks, have them fixed right away before they cause bigger problems.

-Check for clogged filters – if debris (like dust) builds up over time in your AC unit’s filters, it can block airflow and cause your AC to work less efficiently.

Symptoms of an Un-Serviced AC System

When your car’s air conditioning system doesn’t get regular service, the internal components can start to wear down and fail. This can create various problems, from mild discomfort in hot weather to unbearable heat and humidity in the summer months.

Here are some common symptoms of an un-serviced AC system:

– Trouble turning the car on in hot weather

– Poor air conditioning performance in warm weather

– Increased noise and vibration when driving in heavy traffic

– Smelly AC vents

If you notice any of these problems, it’s time to take your car for service. Having an AC system serviced regularly will help keep it running smoothly, preventing any big problems from happening down the road.

How to Test If Your AC Needs Service

If you’re like most people, your car’s air conditioning doesn’t always work as well as it should. About 20% of cars on the road don’t have functional AC. If your car is one of those 20%, it might be time to get it serviced. Here are a few tips on how to test if your AC needs service:

1. Fill up the gas tank and turn on the car. If the AC works, the engine should start, and the air conditioning should work, too.

2. Drive to a warm place and turn off the car’s engine. If the AC still doesn’t work, your car likely needs service.

3. Open all of the windows in the car and check to see if any of them will close properly. If they do not close properly, something is blocking them from completely shutting down (like debris). This could be a sign that your AC needs service.

What to Do If Your AC is Un-Serviced

If you live in a hot climate, keeping your AC serviced regularly is important. If your AC isn’t serviced, it can become less effective over time, making it harder to stay cool in the summer and fall seasons. 

Here are some tips on what to do if you never get your car’s AC serviced:

1. Check the Air Filter- If your air filter is dirty, it can block air from flowing through your AC unit. To check if your air filter is dirty, open the hood and look for debris or dust on the air filter or the fan blades. If these are blocked, the AC won’t be as effective. It’s important to clean the air filter at least once a year.

2. Check for Leaks- Any leaks in your AC system will cause the unit to work less effectively and could even result in a breakdown. Look for water or fluid seeping from around the seals or joints in the system. If you find any leaks, call a licensed technician to fix them before they become too big or dangerous.

When to Replace an AC System in a Car

AC systems in cars can become compromised over time and may need to be replaced. Here are four signs that your AC system may need to be replaced:

1) Your car consistently experiences high temperatures inside and out.

2) The system makes unusual noises, such as buzzing, hissing, or screeching.

3) The AC doesn’t seem to be working as well as it used to.

4) You have noticed increased symptoms such as drowsiness, poor air quality, or headaches when driving in hot weather.


Getting your car’s air conditioner repair regularly is important if you live in a hot climate. Not only will this keep your car cool and comfortable in the summer, but it will also help prevent costly breakdowns. 

If you neglect to service your AC system regularly, there are some common signs that it is time for a visit from the mechanic: Your AC will work sporadically or not at all; you’ll notice an increase in engine noise, or you’ll notice condensation building up on the inside of your windows.
