Why Isn’t the AC in My Car Blowing Cold?

June 15, 2017 3:58 pm Published by Leave your thoughts

We like to think that summer is a time of year meant to be spent cruising with the windows down on the open road. But, in many cases, that scorching sun and high humidity make keeping the windows up a better option… so long as your auto AC works properly, that is. If you kick on the AC and it blows lukewarm, hot or stale air, it’s a problem worth asking your mechanic about.

Often, auto AC repair in Port Charlotte, FL boils down to a few key problems. The symptom might present as air that’s not cold, but once a mechanic traces it, the root of the problem is likely to be one of a few different issues. Here are some factors that may be contributing to the issue.

Refrigerant problems

The most common auto AC problem presenting as warm air is a lack of refrigerant in the system. Refrigerant is responsible for cycling the compressor, which is critical in producing the cool air that you’re looking for when you turn on the AC.

Low refrigerant issues are easily solved by inspecting the refrigerant lines. Most commonly there’s a leak, which depletes the refrigerant. Other times there might be a kink in the hose that restricts the supply and causes problems for the compressor. A mechanic will make sure there’s adequate refrigerant and that the supply is uninterrupted.

Condenser problems

As mentioned above, the condenser is what’s actually responsible for producing the cool air in the AC system. If this is broken or damaged, it’s not going to be able to produce that air. In most cases, debris will be the issue here, blocking the condenser from operating effectively. In other cases, age and general use can finally give way to failure. Either way, the unit will likely need to be replaced before your vehicle is capable of blowing cool air again.

Electrical problems

Your auto AC system is partially reliant on electrical components to run. Specifically, the cycling switch is important for providing power to the condenser. If this switch isn’t receiving power, it can’t tell the condenser when to switch on. No power means no pressurization of the refrigerant, which means no cool air.

Cycling switches don’t often break or need to be replaced—the issue here is in the electrical supply. A mechanic will examine the wiring and fuses first, to make sure the problem can be addressed.

Get your cool air back

Trying to get through the summer months without cool air in your vehicle isn’t going to go over well—especially when you’re forced to drive somewhere on a triple-digit, high-humidity day. Before this situation becomes an unsavory reality, make sure you’re visiting a mechanic for auto AC repair in Port Charlotte, FL.
