It’s that time of the year where the sun is beating down and many drivers are starting to notice that their vehicle’s air conditioning system isn’t doing the job.

Here are a few possible causes behind this problem:

Low on freon: The car could be low on refrigerant, which means that it likely has a leak. Air conditioning leaks could be coming from multiple locations, including fittings and rubber gaskets.

Malfunctioning expansion valve: It’s possible that the problem lies with the expansion valve, which helps control the amount of freon that flows through the A/C system. This component may not be working correctly.

Electronic Climate Control System: Another part that could be failing is the Electronic Climate Control System. This function determines how cold or hot it gets in the front of the car.

Operator error: Today, the setup for car A/C systems vary. So, it’s very easy to hit a wrong button — or not the one you should. It’s a good idea to read the owner’s manual and make sure you aren’t missing something.

Constricted air conditioning condenser: You might also want to check to see if the condenser is constricted. Due to improper cleaning or an impact, the fins could become bent and block the airflow.
