Signs Your Car’s AC Is Going Bad – And What To Do About It
Have you ever been driving down the road, enjoying a nice cool breeze blowing through your car, when all of a sudden the AC compressor decides to start going crazy? It might start making loud noises, over-heat, and eventually lead to an AC failure.
So, what’s the deal? What’s the reason behind it? Can it be fixed?
Read on as Mandal Buick/GMC explores some of the reasons why your AC compressor might be acting up and provide some tips on how to troubleshoot and hopefully fix the issue. We are going to help you stay cool!
Reasons Your AC is Acting up:
Let’s look at some reasons why the AC is being troublesome.
One of the most common is that the refrigerant gas has leaked out and been replaced. The relieving part is that it is a relatively easy fix; however, it can be expensive if you take your car in for service.
A Seized Compressor:
Another reason your AC might not be working is that the compressor is seized up. When this happens, there’s usually not much you can do about it short of taking it into a mechanic and paying for repairs (which could potentially cost more than just buying a new car).
The third possibility – and unfortunately also one of the most common – is something problematic with the car’s electrical system. It could mean anything from a loose wire somewhere in your vehicle’s wiring harness (which could cause a short circuit) to an issue with the control module itself.
Issues with Components:
Finally, another possibility is that there might be something wrong with one of the components inside your car’s air conditioning system – specifically, either its condenser coils or evaporator coil. In some cases, this type of failure is caused by corrosion built up over time and can’t be cleaned off due to lack of maintenance (or just plain neglect).
Other times though, it may have been caused by physical damage such as getting hit hard enough during impact not to function correctly any longer.
Whatever the reason for your problem – whether it was caused by yourself inadvertently causing harm to the unit or nature taking its course with age – there is always hope since you can replace these parts quickly enough!
What Can You do?
If you think your AC is bad, try replacing this part first before calling an HVAC technician. It’s possible that it is simpler than you think and may even save money in the long run if it goes according to plan!
Replace Condenser Coils –
- Check for debris such as leaves or dirt blocking them from circulating air properly.
- Try cleaning them with a solution of water and vinegar (one part each).
- Make sure they’re dry before putting everything back together so no moisture seeps inside, which can cause corrosion over time.
If you’ve checked the condenser coils and they seem fine but still have problems with your AC, then it might be time to consider replacing the evaporator core. It is responsible for cooling the air as it passes through. If it’s clogged with dirt or ice, it won’t be able to do its job.
