On start AC is working fine, after 5-10 mins i am starting to hear loud fast clicking noises.!?
AC died end of last year, simply not blowing cold air. I did nothing. This spring there was not refrigerant in the system, so i went to recharge it. There was a leak. I replace the line from condenser to evaporator, because it was leaking on connection between two hoses. Again my AC was not working, then my mechanic replace the AC control module, and finally AC starts to blow a cold air. Now after a 5-10 mins of working i am starting to hear loud fast clicking noises from the compressor department. Noises are very fast and loud, rapidly repeating. When i turn off AC, they stop. Again when i t
Experienced mechanics share their insights in answering this question :
The compressor clutch on the vehicle may be caused by an excessive clutch to pulley gap or an excessive resistance in the compressor field coil. A check on the gap in the pulley to clutch can be performed by using a feeler gauge and the coil can be checked using a multimeter. If either is out of specs then repair or replace it as necessary. I’d suggest getting your vehicle inspected by a qualified technician, such as one from YourMechanic, to perform these checks and properly diagnose your A/C issue firsthand.

Clicking noises are completely normal if they occur when your HVAC system is turning on or off. A clicking noise when your unit is starting up is caused by your thermostat communicating with your unit. This is not cause for alarm.
Clicks & squeals noise
It`s typical for the air conditioner to make a quiet clicking sound. The AC compressor clutch is probably what you`re hearing. A worn clutch, on the other hand, can make a loud click. As a result, you should consider this a warning signal.
Squealing is a sign of high internal pressure and dangerous operating conditions. You`ll hear the squealing sounds as the air conditioner first starts, and they last only about 10 to 15 seconds. A less severe cause of squealing noise from an air conditioner is dry fan motor bearings or a loose fan belt.
When it comes to air returns making funky noises, though, there are usually a few common culprits: Dirty air filters and/or air ducts: Typically, air returns are covered with vents or grills. Since the air return sucks air, they are prone to getting clogged, especially if your home is particularly dusty.
When you adjust your settings, you may hear a quick, soft clicking. This is usually due to your AC`s relay turning your AC on and off. If that clicking is loud and/or continues for more than a few seconds, you probably have an issue with a broken relay or a worn wire in your thermostat.
A low, steady blowing noise is normal for an air conditioner, as it continually blows cool air through the ducts and vents of your home. This noise should be quiet enough to disappear into the background.
Clanging or Rattling: These sounds are likely because of a loose screw or a piece of debris. But sometimes it`s a piece of a more important component such as the compressor. The compressor is airtight, so if something breaks off inside it, you might be stuck with an unpleasant rattle until it`s fixed.
Fixes for Noisy Fans
Open the air conditioner cabinet and locate the fan. Remove any debris you see on or around the blades. In some cases insulation or other items may fall into the unit and be noisy due to the movement of the blades. If the problem is not debris, then check to see if the blade itself is loose.
Check to see that the cooling fans on the condenser or radiator are running when the air –conditioning is on. Look for any restrictions like leaves, bugs or dirt that would keep air from passing over the condenser. Check the cabin air filter to ensure that it is not clogged.
AC Works Intermittently: When the air goes from cool to warm to cool again, you`re experiencing intermittent problems. This is often due to a clog in the system, a failed compressor or compressor clutch, a faulty condenser fan, a clog in the system, or the actuator directing airflow has failed.
The job of the compressor is to pressurize the refrigerant, turning it from a gas into a liquid. The condenser`s role is to further cool down the refrigerant and exchange heat with the surroundings.
As I have stated several times previously, every mechanical relay has a little electromagnet in it, and when it is energized it pulls the internal switch contacts together. That makes an audible clicking sound. You also can feel the contacts closing if you lay your hands on the relay.
Common Air Conditioner Making Noise Sounds. There are several different sounds your air conditioner making noise can sound like when it needs attention. So if you hear any of these while your air conditioner is running, it`s advised that you turn your system off and call an HVAC service provider.
Ideal Air Conditioner Sound Level
Most people do not want their air conditioners to be louder than an average conversation. Thus, you should aim for your air conditioner sound level to be anywhere between 40-60 decibels at the most. A quiet air conditioner has a sound level below 40 decibels.
Ticking, rattling, clicking or rumbling: A loose piece of hardware could cause sounds like this to occur near the compressor. Hissing or screaming: A loud hissing or screaming noise from the compressor could indicate dangerous levels of pressure inside the unit.
An AC compressor running loud could indicate a big problem. There are many reasons why a compressor isn`t working right. Sometimes it`s as simple as a power issue. Unfortunately, it`s usually due to part failure.
CHECK DAMPERS AND ACTUATOR
Dampers can either be open or closed. Check the dampers on the supply side of your ductwork and try opening them up one at a time to see if this reduces the popping and banging noises. You can also adjust the actuator inside of the duct dampers up or down to reduce the duct noises.

My 2003 ford explorer wont start up just get click click click click click click click click
ANSWER : If the battery is weak and the voltage is dropping to below 9 volts you will get the clicking without the starter turning the motor. Have the battery voltage checked and if battery cannot hold a load then replace it and clean the battery terminals and recheck system to see if it starts.
Honda Civic 2008. AC stopped working suddenly and engine check light came ON for a day.Next day AC worked and no engine light.
ANSWER : Hi there. In both cases, when an AC system is not working and a warning light is coming on the dashboard, typically a professional mechanic will complete the same initial inspection, which is to download the stored error codes that triggered the warning light initially. This tends to give them an idea as to what is causing the problems. This could be something as simple as an electrical relay that is faulty or loose or an indication of a computer related "glitch". Either way, the best way to move forward is to have a professional mobile mechanic complete a check engine light inspection.
Brief, loud clicking noise from dashboard area when AC is turned on.
ANSWER : The noise you are hearing is one of the HVAC door actuators that control air flow or temperature for the a/c. There are at least 4 of these actuators in your system and one of them is going bad and would need to be replaced. The one that is making the noise It’s hard to specify wxactly which one without checking the system first hand. In order to find the one going bad a mechanic would have to have their hand on each one and turn on the a/c and feel to see the failing actuator. Only then can a complete diagnosis be done. I recommend having a mechanic. like one from YourMechanic, come to you and diagnose your HVAC problem.
Fuel pump engages. Batery good, alternator good volts, jump start helps when wont start. Temp does not matter. Intermittent?
ANSWER : Hello. Thank you for writing in. There are several reasons your vehicle may only start when jump starting. The first and most common is a build up of resistance that is causing you to need a boost of voltage to get the engine started. This may be due to poor battery cables, a bad ground connection, a poor starter solenoid, and a couple of other issues. The first thing you want to do is perform a visual inspection of the starting system. Make sure there is no corrosion build up in the battery cables. You can also check the resistance across these wires and make sure you have a solid connection between components. You then want to make sure the starter solenoid is doing its job. It is responsible for taking the small amount of electricity sent by the ignition and turning it into a huge electrical charge that is strong enough to push over the engine with the help of some gear ratios in its favor. Do some more testing, and stick to the basics before assuming its something seriously complicated.
10 loud clicks every 10 min from the AC and Heater Control panel area.
ANSWER : What you may be hearing is the a/c temperature or mode door actuators clicking when they get to one end of their travel of the door they control. This is not normal and you should try to isolate the noise to what actuator is causing the noise and then have it replaced.
When turning on the key I hear a loud click from under the hood but it won’t start the engine.
ANSWER : This is a common sign of a faulty starter solenoid. The starter solenoid is located on the starter and has internal electrical contacts that transmit electricity to the starter. When this fails, it may cause a clicking sound and will not allow the starter to engage the flywheel when you turn the key. If you need help with this repair, I would suggest having a professional from YourMechanic come to your home to diagnose your starting issue firsthand and service your starter as necessary.
Car gets stuck in park and won’t start SOMETIMES. Hear one click upon starting but starts working after a few times.
ANSWER : The shift interlock and the intermittent starting issue are likely separate issues. However, the brake light issue may be related to the shift interlock problem as the circuitry and components are common. The intermittent starting is relatively easy to diagnose. During the next such episode, simply check for 12 volt power to the starter solenoid with the key held in the start position. If 12 volts is reaching the solenoid with the key in the start position, and the always hot lead to the starter has no voltage drop, that likely means you need a new starter. On the other hand, if there is no power to the solenoid, that means there is an interruption somewhere in the starting circuit. To obtain a resolution of this issue, you can request a hard start diagnostic. With regard to the shift interlock, and brake light issue, the relevant service to request is a shift interlock diagnostic. If you request these services, the responding certified mechanic will get this taken care of for you.
