Why Is My A/C Blowing Hot Air?
As the temperatures rise into the summer months, A/C becomes a routine part of driving. Without it, the interior of your vehicle can reach near-unbearable temperatures on hot days. In this article, we’ll be going over what causes hot air to blow from your A/C and how to fix it.
Low Refrigerant
Here in Peoria, low or leaking refrigerant is the most common cause of a malfunctioning air conditioning system. It’s the fluid that circulates through the system, constantly expanding and contracting to cool the car’s interior. This refrigerant is contained within a closed loop, preventing it from evaporating over time.
However, as A/C system components wear down and age, they can develop leaks that allow the refrigerant to escape the system and deplete the supply. Without sufficient refrigerant, the air conditioning system loses its cooling properties, and the air being circulated into the cabin will not be cold.
Clogged Condenser
The condenser relies on air moving through it to create cooling, so naturally over time it can become gunked up with dirt, dust, and debris; it’ll lose its effectiveness. If the problem is a broken condenser, it’ll need to be replaced entirely.
Faulty Electrical System/Fuses
One of the more frustrating issues to repair, electrical malfunctions are a common cause of a faulty A/C. Diagnosis commonly consists of visually inspecting the wires and fuses within the air conditioning system to try and pinpoint the faulty connection that may be causing issues.
Taking your vehicle to a trusted professional is your best bet for efficiently finding and repairing these electrical issues, as they’ll have the testing equipment to accurately diagnose and replace the root of the problem.
Bad Compressor
Regardless of how full of refrigerant your vehicle is, it won’t mean anything without a working compressor to pump it into the system. Over time, it’s normal for compressors to wear down, eventually losing functionality altogether. It’s also common for them to fail after a long period of not being necessary, such as a long and cold winter. We recommend running your compressor during the winter months every once in a while for 10-15 minutes.
You should never ignore issues with the compressor, and it should be taken to a trusted professional to ensure proper diagnosis, removal, and installation. If your compressor is broken, it will likely require a replacement.
