Five possible reasons why your air conditioning isn’t working

In Vehicle Maintenance by HomeTowne Auto Repair & Tire

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.
