Common Warning Signs You Need A/C Service
It can be difficult to know exactly when your system is failing before it completely gives out. We recommend bringing your vehicle in if you experience any of the following symptoms:
-
Weak airflow or a completely dead blower motor.
-
Unpleasant, musty, or moldy odors coming out of the vents.
-
A loud clicking noise when you flip the A/C switch on.
If you smell a musty odor or notice weaker airflow inside your vehicle, the culprit is often a dirty, clogged cabin air filter. We recommend checking this during every A/C inspection.
