My AC is having trouble working properly. Sometimes is blowing warm air, sometimes it gets back to cold air. Have no idea what's this. And now that the summer kicked in, the heat is a big problem. What should I do?
I had kind of the same problem with my car's air conditioning. There can be more issues that can cause this kind of result. So it is better to go to service and they will repair faster and better in comparison with us. In my case, there was refrigerant leak, but in your case there can be other things like faulty condenser,
broken compressor or problems with the electrical system, that's why I tell you to better go to service. I have a friend working for aircon servicing and he fixed everything in my car.
I think the ventilators may have broken down... I had the same issues with my aircon where it did not blow any cool air anymore. Maybe you could read up on these aircon servicing articles on lkbrothers.com that could help, before bringing it to a mechanic.
