Signs Your A/C Needs to be Recharged (and/or Repaired)

Trying to beat the summer heat? Make sure your car’s air conditioning (A/C) system is up for the challenge! But since it works overtime during this season, your A/C is more likely to have issues and may even need to be recharged. Let’s go over what A/C recharging is, signs your system needs it, and how to maintain your A/C to keep it healthy.

What is A/C Recharging?

Your car’s A/C is a closed system. This means the A/C circulates the same refrigerant constantly to cool the air. A refrigerant leak, component damage, or some kind of system malfunction can lead to the A/C needing a recharge. A/C recharging is often done as part of overall diagnostic testing to check for problems.

To recharge your A/C, a technician will hook your car up to a machine that will remove all the refrigerant while simultaneously putting the system under vacuum. This will test for leaks and determine whether the system can hold a vacuum for a certain period. If any leaks are detected, the technician will schedule repairs for them. If the system is clear, new refrigerant will be added and the system will be checked to make sure it’s running properly.

Signs You Need an A/C Recharge

Your car may be signalling that it needs an A/C recharge if:

• The A/C is only blowing warm/hot air.
• You can see a refrigerant leak.
• The A/C clutch is not engaging.
• A weird smell is coming from the A/C vents.

If you notice any of these symptoms, take your vehicle to a NAPA AUTOPRO service centre to have the A/C system professionally recharged or repaired. For a temporary fix, you can top up your refrigerant to get some cool air flowing into your cabin, but that won’t eliminate the need for repair.

(Note: Most A/C systems made before 1995 can’t be recharged.)

Cost of recharging your A/C

Getting your A/C professionally recharged will typically cost between $100 and $300. That price will vary depending on your car’s make and model. Further repairs cost extra. If new parts are required, most A/C system repairs will cost between $300 and $500.

Your refrigerant will run out over time and will need to be replaced during a recharge. Aside from when you notice an issue, have your A/C system recharged every three or four years.

You can recharge your A/C yourself with a recharging kit but going to a professional is recommended in case you miss a step or overcharge by accident, leading to a more expensive repair.

A/C Maintenance

To avoid repairs, keep your A/C system in good condition with these tips:

• Run your A/C on defrost mode for ten minutes every week on the coolest setting with the fan at maximum speed (even in the winter). This will help maintain gas pressure and keep the compressor running smoothly.
• Don’t pre-cool your car. The A/C operates at maximum efficiency while you’re driving.
• Use the windows when you can to give your A/C a break in the summer.
• Clean or replace the cabin air filter every 12 to 24 months.

Pay attention to any changes in your A/C system, including strange noises, smells, or warm air. If you notice anything out of the ordinary, take your vehicle to a NAPA AUTOPRO service centre. Solving these issues early on is best for the health of your vehicle, your safety, and your wallet!
