My car is a 2008 Hyundai Sonata with 155k miles. AC has been always working great and system has never been opened. However, there has been some strange noises with it. Whenever I have it around 68 degrees, it makes some strange hissing sound, and when I turn off the AC and the compressor disengages, it makes a sound like metal is being hit, like when you push in a soda can.
At the miles I have, I'm just concerned how much longer the AC is going to last, most people I know will have already had a new compressor or AC trouble way before 100k miles. I guess Hyundai does make very good AC systems.
I'm in the market for a new car, and looked at Chevy Traverse and Equinox, but throughout the years, everyone I've known who has owned a Chevy has had AC trouble after 30k. Do they still?
another thing I noticed is my AC never cycles which is great compared to my Honda Civic that constantly cycled and never really cooled. every 20 seconds, it would make that sound of the compressor engaging and disengaging. Perhaps my car has pressure switches instead of a cycling switch?
Part of the reason why I bought a Hyundai Sonata is cause of the non cycling AC.
I've also heard that getting an AC performance check will infact put air in the system and will take out alittle refrigerant. Is that true?
Hissing noise is just the refrigerant flowing and nothing to worry about if you're getting good cooling. Your Civic had something wrong with it, they should not start to cycle until it is cool inside. Rapid cycling with poor cooling is often because the condenser fan is not working.
Thats why I got rid of it. I don't trust the dealership to buy another Honda because they never fixed the civic in the first place so if I have another issue with.a new honda, they wont ever fix it.
