Air conditioning not working well

The air conditioning is not working well. I recently had the refrigerant refilled, and it works but is not strong.
Experienced mechanics share their insights in answering this question :
A very common culprit for low A/C temperature is a part called a cabin air filter. I have seen many cases where responsible car owners did not even know that it existed. If the A/C system seems to be operating correctly, but the air temperature does not have the "oomph" that it is used to, it is very possible that your Honda Accord has a dirty cabin air filter. The cabin air filter is responsible for trapping all of the debris, pollen and other contaminants from passing the fresh air ducts, so the air you breathe in you car is clean. You can verify the location of your Honda’s cabin air filter in the owner’s manual. From there you can inspect it, but there is a good chance that it will need to be replaced. A cabin air filter replacement can be performed by a certified mechanic to allow for a cleaner air flow and a colder feel than before.

Perhaps the most common cause of AC issues is clogged filters. Dirt, pet hair, pollen and dust can clog your filters. When filters get clogged, they begin to restrict the flow of air through your AC. The result is that the AC doesn`t cool your indoor air effectively.
There can be a number of reasons why you can air conditioning is not blowing cold air. The most common reasons could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge (regas) your air conditioning.
The most common reasons a Honda Accord ac isn`t working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor. You may not realize there`s a refrigerant leak until the air conditioner stops blowing cold.
The most common cause of a vehicle`s air conditioner not getting cold enough is that it needs to be recharged. You can recharge your refrigerant by yourself, but to save time and make sure the job is done correctly you should make an appointment with your local professional auto shop.
If your air conditioner is running, but not lowering temperatures inside, one issue could be a blocked or clogged condenser coil. When operating correctly, the condenser fan draws air into the outdoor unit through the condenser coil to pull heat energy out of your home.
AC Not Cooling FAQs

Your air filter is dirty and clogged which restricts air flow. You may have a blocked or clogged condenser coil. The coils may be frozen. The compressor may not be running.

To reset a malfunctioning Honda Accord climate control system, turn on accessory mode, then hold the defrost and OFF buttons on your climate control unit until the light has blinked five times.
Honda has a history of having AC problems, which could lead to defective systems and components that can leak refrigerants. If you experience any of the symptoms described above, it is important to reach out for help as soon as possible in order to minimize damage or loss.
If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC. You don`t need to tolerate a stuffy, uncomfortable car, and you don`t need to rely on the shop to fix the problem either.
So, if your air conditioner isn`t cooling, and you suspect a refrigerant leak, or if you`ve checked the air filter and thermostat to no avail, yes, you should shut your air conditioner off and call us right away.

My 2003 Hyundai air conditioning works fine but often starts blowing hot air, especially when idling.
ANSWER : Hi There,
It sounds like you may have a condenser fan that may not be cooling the AC condenser properly. As you may know, the job of the AC condenser fan is to cool down the AC condenser as it generates a lot of heat during the course of its primary function, which is to convert the AC gas refrigerant into a liquid form, a process that generates a significant amount of heat. As the AC condenser fan blows cool air across the condenser, this allows the condenser to remain cool, keeping the pressure down in the AC system which helps to generate cooler air. I would suggest having a professional from YourMechanic come to your location to take a look at your vehicle.

Air conditioning doesn’t work – 1988 Jeep Grand Wagoneer
ANSWER : Check the fuse for the heater/AC blower motor. If the fuse is good, then either the blower motor resistor or the blower motor itself is suspect. The blower motor resistor provides for multiple speeds for the blower motor. A professional mechanic, like YourMechanic, can diagnose and replace the failing component.

Hot air mixed with cold blows from air conditioning
ANSWER : Hey there. You will most likely have to have a mechanic bypass the heater coolant lines to have this resolved. Your A/C may not be controlling the air flow inside the evaporator correctly out of the vents and may be the blend door actuator stuck in the heat position. Have the AC system diagnosed first before bypassing the heater.

Air conditioning not working in the front of my SUV
ANSWER : My guess is that the refrigerant level is low (from a leak somewhere) or there is a problem with the AC pressure cut out switch. The control module will cut power to the AC compressor if it determines the system does not have the correct pressure due to a low refrigerant level.

Disconnecting the battery probably temporarily reset the control module. There may or may not be codes stored in the HVAC system to aid with diagnosis.

You should be able to wiggle the large fuse out with your bare hands or gently remove it with a pair of pliers.

Finally, I do not think any of this has to do with the oil change that was performed.

Air conditioning is blowing hot air – car stalls when A/C is on
ANSWER : In order to diagnose all the different problems you have, I having the A/C pressures checked to see if the system is low on refrigerant from a leaking compressor or another component. The rough idle may be due to a dirty throttle body and idle control system. If you would like to have this checked for you, a certified professional from YourMechanic can come to your car’s location to inspect the A/C and rough idle in order to proceed with the proper repairs.

The 1998 Nissan Maxima air conditioner was working fine then it slowly start working at all there was no air no vent blowing.
ANSWER : The blower motor, and resistor block, are beneath the dash on the right (passenger) side of the vehicle. What you are describing sounds like a failure of the blower motor that circulates air in the HVAC system, however, there are certain faults that could occur in the electric circuit that powers the blower motor. If power is reaching the blower motor when the blower switch is in the on position and the blower motor is not functioning as intended then the blower motor is condemned and replaced. On the other hand, if there is no power, then the blower switch and the plug connection on the back of the switch, as well as the rest of the circuit should be inspected. If the circuit includes a blower motor resistor block, of course the resistor block has to be checked for continuity (i.e., specified resistance in ohms) at each position. If equipped with a relay in the circuit, that is easy to test and if the relay works consistently as commanded, you can assume there is no fault there. If you want these diagnostic steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a non functioning cabin heater diagnostic and the responding mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic.

When idling, car overheats and A/C blows hot air – 2001 Saturn L100
ANSWER : Hello. The most likely cause of the issue that your are having would be a faulty cooling fan. The cooling fans purpose is to keep the radiator and condenser for the air conditioning cool during the idling function of the vehicle.

If the cooling fan is not working, this will cause the radiator and condenser to get very hot. When the radiator and condenser get hot, this can cause the vehicle to overheat and the air conditioning not to work. When the vehicle is driving at higher speeds, the force of air that is created towards the vehicle will flow through the radiator and condenser and therefore keep them cool. I would recommend having the cooling fan checked to make sure that it is working properly. If not, I would recommend having the cooling fan replaced.

Air suspension valve not working pump works but no air comes out of valve to struts
ANSWER : If air is getting to the valve but not coming out, odds are yes the valve is bad. Unfortunately there is no rebuilding kit for them. It most likely will have to be replaced then the entire system will need to be checked for any other leaks or faults.
