2 Possible Reasons Why Your Car's Cabin Feels Humid Even With The AC Running
Normally, a few minutes after you get into your hot car and run the air conditioner, the air starts to feel cool and comfortable. However, you may have noticed that the air feels muggy, making it feel as though even the lowest temperatures are not enough to cool the air.
If the air has suddenly started to feel humid in your car no matter how long your run the air conditioner, there may be an issue that requires the attention of an AC repair technician. Below are a couple of possible reasons why your car's cabin feels like a sauna, even while the air conditioner is running.
1. Low Refrigerant Level in the System Is Creating Inconsistent Temperatures, Affecting the Humidity Level
One common reason why the air in your car's cabin feels humid is that the refrigerant level is low. When the air passes over the refrigerant-filled coils, they not only cool the air but also condition it by removing the excess moisture, making it feel cooler and dryer once it reaches the cabin. However, if the refrigerant levels are low, you may still intermittently have cool air coming out of the cabin vents, but it will feel humid because there is not enough refrigerant to pull out the moisture. Having a technician check and refill the refrigerant usually fixes this issue.
2. Surfaces of the AC System's Condenser Coils Are Obstructed or Damaged, Keeping Them From Pulling Moisture From the Air
Another possible reason why the air in your car feels muggy is an issue with the surface of the system's condenser. This is especially true if the refrigerant has already been checked and is filled to its recommended level. Even if full of refrigerant, if the condenser coils are damaged or obstructed by dirt, grime, or debris, they will not be able to lower the air humidity. A technician will need to examine the coils to see if they need to be cleaned or repaired.
If the air in your car's cabin feels muggy, you may need to have the refrigerant refilled so that the system can maintain a consistence temperature and humidity level. If there is sufficient refrigerant, there could be an issue with the condenser that is preventing it from pulling moisture out of the air. Whatever issue is causing the increased humidity, do not try to fix it yourself. Instead, take your car to an auto shop that offers car air conditioning service to have a technician take care of the problem for you.
