Drove truck on Wednesday and AC was blowing cold. Thursday morning there was an odor it wasn't a mildew odor it was more like a plastic smell. Can still smell it when turn AC on.
My car has an automatic transmission.

The smell could be caused by a coolant leak, an electrical issue, the A/C compressor overheating, or simply an outside smell. Sometimes, plastic bags tend to get stuck to the exhaust system and melt. If you had the vent on for outside air, you probably smelt a bag burning, or some ambient smell.
The most common reasons a Ford F-250 Super Duty 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.
Overheating Motor – The fan that throws hot and cold air throughout your home needs a motor to work. The bearings of this motor get worn out due to extended use and overheat the motor producing burning plastic smell. This is a normal occurrence and nothing to be alarmed about.
Dirty condenser
If your HVAC system is not blowing cold air, then your condenser might be clogged. This means your air conditioner is working harder to pull the air inside your home. Luckily, if the condenser is the problem, you can fix it without the help of a technician.
If you notice your air conditioner smells bad like dirty socks when turned on, you can check the evaporator coil for mold growth by removing the access panel on the indoor unit`s cabinet and take a peek. If you see mold, call your HVAC technician to fix the problem by cleaning the coils with appropriate cleaners.
Have Low Refrigerant Replaced. Sometimes AC units can run out of refrigerant. If the rest of your AC is fine but it`s not blowing cold, you`ll need more refrigerant. You`ll need a professional to replace your refrigerant.
The reason AC filters become smelly is because when dirt gets trapped on it, it can cause spores to grow and the odor gets trapped or passed on to the air. Dirt builds up in the filters also restricting airflow, trapping more moisture in.
Electrical shorts, burning wires or hoses, and even excessive dust in the vents can cause a burning plastic smell in your vehicle`s air conditioning.
This might be causing the problem if: The burning smell from AC unit is plasticy or has a tinge of sulfur to it. The electrical components in your HVAC system have a plastic casing around them, so if the bring smell from AC unit has a plasticy tinge, it may be that some of your wiring is overheating and malfunctioning.
Q: Does cleaning the AC filter make it colder? In a sense, yes. A clogged AC filter can trap cold air inside the air conditioning unit, preventing it from circulating through the ductwork and into the home. Replacing the filter improves that air flow, thereby allowing colder air to make its way inside.
A clean air filter will not impede air flow in and out of your unit. However, a dirty air filter will restrict the flow of cold air, causing it to build up inside the ac unit and lower the temperature.
Spray the inside of the evaporator coil with a foam coil cleaner. These cleaners can be found at your local hardware store and should have instructions for proper and safe use. Spray a liberal amount of the cleaning, making sure to coat the entirety of the coil.
The most common smell is dust. That`s completely normal. After sitting for months, dust will accumulate in your system and the AC just needs to burn everything off. If you`re still smelling something funny after a few days, it may be time to give your HVAC technician a call.
Broken Capacitor The capacitor is an item in your air conditioning system that powers the motor. If this item fails, the motor can overheat and give off an unpleasant burning smell. The capacitor can break for many reasons, including power surges to general wear or overheated circuitry.
If your air conditioner is blowing out warm air, your unit`s refrigerant levels might be low. This usually indicates a refrigerant leak in your system! If that`s the case, your air conditioner will continue to run and blow out warm air, trying to reach the temperature you set on your thermostat.
The most common causes of broken air conditioning are leaks or compressor issues. 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.
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.
What Causes Dirty Sock Syndrome? “Dirty Sock Syndrome” refers to when a foul-smelling, mold- or mildew-like odor comes from your air conditioner when you first turn it on. This happens when moisture, dust, and dirt build up on your AC system`s evaporator coil, inviting bacteria and mold to multiply.
Yes, you can use your air conditioner to remove unpleasant smells from your house. The best method to achieve this is to open the windows up a little more than usual and then start the air conditioner in “ventilation” mode on one of the higher fan speeds. This will exhaust the smells out of the building.
“What you`re probably smelling is the condensation that comes from the evaporator inside your heating and cooling system,” says Jake Fisher, Consumer Reports` senior director of auto testing. “Basically, water collects in that area and, if it sits long enough, creates the musty smell.”
This smell has been described in many ways – musty, rotten eggs, dirty socks, fishy, burnt plastic, gas, to list a few – and can even be accompanied by the feeling of being short of breath, dizziness, or headaches. No one wants that! Let`s talk about why these smells occur and how we can prevent them.
Freon usually travels through closed copper coils in an AC unit, but these coils can crack and result in an AC coolant leak. A freon leak will produce a smell between sweet and chloroform.
Your AC won`t suffer catastrophic damage if it overheats just a little bit. However, the compressor may fail if the AC overheats for a long time or hits dangerous temperatures. The compressor is a major component of an AC, which means compressor replacement isn`t cheap.
Improved HVAC System Efficiency. Last but certainly not least, regularly changing your air filters helps your HVAC system perform more efficiently! If you`ve noticed your home not cooling or heating as well, as usual, check the filter before calling an HVAC contractor.
