In order for the system to continuously control the temperature inside the vehicle, a number of sensors are used to gauge how hot or cool the air is. The information from the sensors is then used to determine how much warm or cool air needs to be pumped into the vehicle to maintain the temperature desired by the users.
Your vehicle`s AC not working is most likely caused by a freon leak or a failing compressor. While these are the simple to spot reasons for the air-conditioning not working inside your car, it could also be anything as simple as a dirty cabin filter or a bad belt.
Climate control uses air conditioning to automatically adapt to and regulate your desired cabin temperature. This system allows for much more automation and is generally controlled using your vehicle`s infotainment/multimedia system.
The blower motor is responsible for sending air through the vents of your car. Over time, blower motors can become damaged, or completely fail. In which case, air will no longer come out of your vents.
There are six major controls of the climate of an area. These factors are latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds.
The recirculation mode is comparatively better. But, if you use it for long, the air inside will become impure. So, during long journeys, you can switch to the fresh air mode once in a while to let fresh air in.
For most central air systems, the process is simple. Simply move the switch on your thermostat from “Heat” to “Cool”. If your system was off entirely, you may need to move the switch from “Off” to “Cool” instead. Once you turn your system on, be sure to close any open windows to conserve energy.
Common Reasons AC Doesn`t Run Cold
The most common causes of broken air conditioning leaks or compression issues. If you are feeling cool — but not cold — air, the issue could be a clogged filter, a problem with the cooling fan, signs of radiator trouble, or it could simply mean it`s time to recharge your AC.
Here are some of the most common causes of why air doesn`t flow out of your vehicle`s vents: Your air intake is clogged, meaning that air isn`t getting in from the outside at all or isn`t circulating properly. There is a blown fuse in the ventilation system. Electrical issues such as a bad relay.
Climate control consistently monitors the temperature in the car and then heats or cools the cabin space accordingly, whereas air-con is more of a manual system where you have to tell it what to do. You set the temperature and fan speed, and then the air con will stay on those settings until you adjust them yourself.
Your car`s air conditioning system is not just for cooling.
It`s a common misconception that your cars air conditioning system is only for cooling down the air in your car when it`s hot out. Your air conditioning system does exactly what the name implies – conditions the air inside the vehicle.
An air conditioner provides cold air inside your home or enclosed space by actually removing heat and humidity from the indoor air. It returns the cooled air to the indoor space, and transfers the unwanted heat and humidity outside.
The main purposes of a Heating, Ventilation and Air-Conditioning (HVAC) system are to help maintain good indoor air quality (IAQ) through adequate ventilation with filtration and provide thermal comfort. HVAC systems are among the largest energy consumers in schools.
One of the main differences between ventilation and air conditioning is that air conditioning does not use an external source. Ventilation on the other hand uses air from outside to help purify the air inside. Additionally, air conditioning can cool the air it provides.
Prevailing winds and pressure belts are major climate controls. A belt of low pressure known as the intertropical convergence zone (ITCZ) lies along the Equator. On either side of the equatorial low, between 25° and 30° latitude in each hemisphere, is a belt of high-pressure centers over the oceans.
WHAT TEMPERATURE SHOULD THE AC BLOW? As a rule of thumb, when the ambient air temperatures 70° degrees Fahrenheit (21° Celsius) and humidity 20%, the AC outlet air temperature should be in the 35°-40° degrees Fahrenheit range.
Recirculation mode, which recirculates the air inside the car rather than bringing in hot air from outside, is usually considered the best mode for AC in the summer. This mode helps the AC system cool the car faster and more efficiently.
As mentioned above, the ideal fan speed setting in cooling mode is high fan speed. Later on in the night, we recommend reducing this to medium or low speed. The ideal mode for your air conditioner is to select either heating or cooling mode, not auto mode.
We recommend keeping vents and interior doors open as much as possible. If comfort is an issue, try closing vents only partially. Closing vents no more than 75% of the way can ensure that air keeps circulating throughout your home so pressure is even and your energy bills stay as low as possible.
The best option with any ducted heating and cooling system is to keep your vents open at all times. This allows optimum air flow for the highest possible energy efficiency. If you want to direct air away from a wall or corner, you can adjust the fins so they`re slightly slanted toward the room that you`re in.
The four main modes on most air conditioners are heat, cool, auto, and fan.
The easiest explanation for your AC not turning on is a thermostat problem. Check to ensure your thermostat is on, set to “cool,” and that the temperature is set to a few degrees cooler than the normal ambient temperature of your home. You may also need to replace the batteries.
If your air handler is running but not blowing air, there are two likely scenarios; either a broken AC blower belt or an issue with the motor itself. If the air handler is humming or buzzing, but not making the mechanical sounds of a motor running, you`re most likely talking about an issue with the motor itself.
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.

air conditioner not blowing air from dash vents, but blowing air from side vents
ANSWER : A few different items can cause the air to not blow out of the dash vents. The most common are a blend door or a control switch. The best method for the AC diagnosis feature can be found in the vehicles owners manual. I recommend having your AC checked by a qualified technician, such as one from YourMechanic, to have the problem diagnosed and repaired correctly.

Cold mist/smoke like air comes out of the air vents when cold air is on.
ANSWER : If you are using regular outside air a/c instead of recirculated air you may be getting a large amount of outside air humidity and can cause a mist to come out of the a/c vents. You should make sure the a/c evaporator drain is cleared and drains freely or the water in the a/c cannot drain fast enough and the blower will pick up the water and blow it out the vents.

My heater is blowing air through the driver side air vents but is blowing cold air through the passenger side and rear console ven
ANSWER : Hi there:
Climate controlled vehicles have multiple electrical relays that open and close vents to maintain the desired temperature. In some instances, these relays can wear out overtime. However, it’s also common for debris to clog up vents (especially side vents) which may restrict the flow of cool air. The best way to determine why your AC is not working efficiently, it might be best to have a professional mechanic complete a AC inspection; so they can pinpoint the source of your issues and recommend the right repairs.

Why is my air system blowing out hot air in spurts and why is the temperature gauge nearing hot while in use?
ANSWER : This can be caused for a variety of reasons such as a malfunctioning thermostat, a radiator not flowing properly, a faulty coolant temp sensor or AC refrigerant not properly being supplied to the AC compressor. Your car’s AC system puts a heavy strain on your car’s engine when it runs as it requires a lot of power to run. When the AC compressor comes on it puts additional strain on the motor that may be already struggling to stay cool as a result of any of the issues named above. I would recommend having an expert from YourMechanic come to your home to diagnose and repair.

Problem with AC/heater – 2005 Ford Explorer
ANSWER : Hello. The problems you describe with the front system may either be a faulty control switch or faulty vacuum motors for the air blend doors. The problem in the rear is likely the rear heater control valve, which regulates the flow of hot coolant to the rear heater core and air duct system. The clicking noise may be a broken vacuum motor for that valve (integrated in the valve).
I would recommend having a certified mechanic, such as one from YourMechanic, come to your location to perform an inspection of the heater and suggest the needed repairs.

My 2016 Toyota Camry had a stagnant water smell coming through the air vents. I asked the service center Not to use any fragrances
ANSWER : This is something I always do in place of perfumed disinfectants. My other half is also sensitive to perfumed sprays. I use a name brand household spray disinfectant. They are available in different scents that you may be less sensitive to. I repeat this process a couple of times per year, or whenever it starts becoming a problem. First, turn the a/c on Recirc with the fan on medium to high speed. Spray the disinfectant down near the floor under the dash on the passenger side. When you set the system into Recirc, the air is drawn in from the heater ducts. Spraying down under the dash gets it pulled up into the a/c evaporator. I do that a few times. Then move the temperature selector to Hot and repeat. Once you’ve done that, switch off the Recirc feature and open the hood. Fresh air for the heat and a/c system is generally drawn in near the passenger side at the base of the windshield. You may even see some sort of grille in that area. With the fan still set on High, spray some more disinfectant in that area so it gets drawn in with the fresh air. Do that a few times then switch the temperature selector back to cold air and a/c on and spray some more. Once you’re done, allow the car to run with the a/c on, the fan on high speed, and the windows open for 5-10 minutes.

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.

Having problems with my air conditioner putting out different temperatures from different vents
ANSWER : Hello. Typically when you experience only one side of the system doing this, it is because of a bad air door actuator motor. These are common failures on most cars. If I knew what kind of vehicle this was, I could give you more precise information. When I come across a problem like this, I remove the actuator and see if it is working when the temperature on the dash is adjusted. If it is not, then I replace it. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair your air conditioning.
