AC blowing warm? Don't assume it just needs more refrigerant.
It's a common misconception, but your vehicle's air conditioning system is sealed. If it's low on refrigerant, there's usually an underlying reason.
The tricky part is that several different issues can cause weak or warm AC. It could be a leak, an airflow problem, a cooling fan that isn't doing its job, or even debris blocking airflow through the condenser.
Simply adding refrigerant without knowing the cause can sometimes make the problem worse instead of better.
When your AC isn't keeping up on a hot day, it's worth finding the root cause rather than guessing. Understanding what's really happening can save time, money, and frustration.
