Why is My Car’s Air Conditioner Blowing Hot Air?

Posted on May 27th, 2020 by ncapmanage

With temps rising, many people in the Chicago area are turning on their air conditioners for the first time in months. High temperatures can mean an uncomfortable ride if you need to go anywhere in the car, and a very stressful one if you have an air conditioner that’s unhelpfully blowing hot air. Why does this happen? Today, we’ll explore a few common causes.

Insufficient Refrigerant Levels

The first thing a mechanic will look at when faced with a malfunctioning air conditioner is the levels of refrigerant. This substance is what enables the air conditioner to cool the passenger compartment; without it, the heat from the car will simply cycle back.

Condenser Issues

The condenser’s job is to remove heat from the liquid refrigerant flowing from the compressor. It will fail to operate properly if its tubing becomes blocked or punctured. A trained AC technician may be able to flush a blocked condenser, but any damage will necessitate replacement.

Broken Fans

If the fans in your AC system are broken, they won’t do much to remove heat from the refrigerant. This kind of disrepair may take a bit more time to notice, as a bit of coolness may continue to come through the system.
