My air conditioner blows hot air on the left side of my car and cold air on the right side of my car. Do you know how I can fix it so it blows cold air on both sides of my car? Thanks.
A common issue across many makes and models with dual AC in the temperature blend door actuator failing and causing drastic temperature differences between the driver and passengers sides. Have the HVAC system inspected by an experienced professional to find the specific cause. A certified professional from YourMechanic can come to your car’s location to diagnose the AC and assist with proper repairs.

Low refrigerant pressure can cause the left side to blow warmer air than the right side, but in no case will low pressure cause the air on one side to be warmer than the outside air. Your problem is that the left side heater is stuck on.
Due to the design of dual AC systems, low refrigerant is the leading cause of drastic temperature difference from one side of the dash to the other. Even well experienced car mechanics may be surprised to learn that as little as 4 to 8 ounces undercharged of 134A can make such a huge difference.
A car A/C blowing hot air is often the result of a refrigerant leak. Refrigerant is a liquid that circulates through your car`s A/C system, expanding and contracting as it removes heat and humidity from the cabin. None of the other A/C components will function correctly without proper refrigerant levels.
That means that the ignition system is working, so you most likely have a fuel system problem. What you want to do is pressure test your fuel pump.
If you have closed your air vents, or your vents are obstructed by furniture or upholstery, proper airflow is being disrupted. This can most certainly cause some rooms in your home to be hotter than others, while placing extra strain on your HVAC system.
First, check for these common problems: Dirty air filter—A dirty filter restricts airflow, not letting your home get enough cool air. Closed vents—Closed vents in rooms can cause them to be hotter than other rooms. Open windows—Your conditioned air can flow out of open windows, leaving uneven temperatures in your home.
It could be as simple as making sure that your filters and fan blades are cleaned properly or making sure that there is no improper duct sizing or high static pressure. In the end, you might have to have your limit switch replaced. The third reason could be due to a faulty fan or motor.
Basically, the temperature blend door is the instrument responsible for sending air over the heater when you turn on the heat, and air over the cooler when you turn on the air conditioning. So, if this door isn`t working, you aren`t going to face a terrible accident, but definitely some inconvenient temperatures.
It may seem counter-intuitive to run your mobile A/C when the weather`s cool, or even freezing, however running the A/C in the winter not only does not do any harm to your heating/cooling system, it may in fact, offer benefits. Simply put, running the A/C and heater will dehumidify and remove moisture from the air.
OPEN WINDOWS OR POOR INSULATION The tiniest crack, lack of insulation, or issues with how your window sits in the sill can make it seem like your AC is not working in one room. If you feel like one room is warmer than others, the first thing to do is to make sure the window is closed all the way and locked.
Improper insulation might make one room colder or hotter than the rest because it`s letting the air out of the room. If you have any windows in your home that are open, go ahead and shut them. They`re letting the cooled/heated air out and letting in the outside air.
Some rooms may be hotter than others if they have more windows in the room, particularly those exposed to direct sunlight. Also, since heat rises, rooms on the upper floors of a multi-level home are likely to be warmer than those below.
empty and usually boastful talk.
Low or Leaking Refrigerant If there is a leakage in the coils or refrigerant lines, the refrigerant level in the cooling unit will decrease, resulting in warm air blowing from your vents or even reduced cooling performance. Over time, the refrigerant leaks can lead to low refrigerant levels.
Help!
They could be dirty, blocked, or closed off. Check your air filters as well. If you are still having issues getting air to a particular zone, you may have an issue with your duct system.
With the AC off, the clutch does not spin. When you turn the AC on, the clutch can make a momentary click and starts spinning with the belt and pulley. If the clutch does not engage, or if it makes a screeching or whining sound when it does, the compressor needs to be serviced.
Air conditioners cannot run without refrigerants. They can function with a low refrigerant level, but air conditioners need the correct amount of refrigerant to work correctly. Running the air conditioner with an inadequate amount of refrigerant is inefficient and can lead to costly repairs or replacements.
Unless there is an actual hole or crack within the compressor holding the freon, the freon level remains the same. Therefore, an AC will never require a recharge of freon unless without the presence of a leak.
The thermostat should not affect the A/C compressor blowing cool air. The thermostat regulates the flow of the coolant in your car`s engine and controls when the coolant flows in and out of the motor from the radiator by opening and closing at specific temperatures.
The car`s compressor does more than just cool the air before it passed through the car. You can use the a/c compressor while controlling the heat setting of the car to control the climate within.
Generally speaking, when cool air blows during early morning hours, and then blows warmer as it gets warmer outside, it can be due to a few possible sources. First, and most common is that the AC vent is set to draw air from the outside and not through the cabin.
Airflow can also be affected by insufficient coolant in the engine, as coolant is responsible for cooling the air that your AC produces. Finally, not having enough coolant might cause humidity issues. If there isn`t enough moisture in the engine block, your AC could dry out the inside of your car.
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.
