Car heating and AC system: what can go wrong and how to keep it working properly?

[MESIgoal]

Hey guys, my car’s AC stopped cooling properly this summer, and now with colder weather coming, I’m nervous the heater might be next. I replaced the cabin filter myself, but it didn’t help much. What are the most common reasons the air system starts acting up? Is it usually something simple or a sign of a bigger issue?

I had the same problem last year — no cool air and later weak heating. A Professional mechanic from an auto repair in Bristol PA checked the system and found a small refrigerant leak plus a clogged vent actuator. They fixed it quickly, and the difference was huge. Regular AC and heater maintenance really helps avoid sudden failures, especially before the seasons change. Now I always get it checked twice a year.

This is a great reminder! I tend to forget about the AC system until it stops working. I guess it’s smart to do preventive maintenance instead of waiting for it to fail, especially before long road trips.
