Weak or Warm Air
Low refrigerant levels or failing components reduce cooling capacity. We diagnose the root cause and restore proper refrigerant levels after repairing any leaks.
Strange Noises
Clicking, grinding, or squealing sounds indicate compressor clutch problems or belt issues. Our technicians identify the source and replace worn components.
Bad Odors
Musty smells from vents indicate mold growth on the evaporator. We treat the system with antibacterial solutions to eliminate odors and prevent recurrence.
Water Leaks
Water pooling inside the vehicle usually means a clogged condensate drain. We clear blockages to allow proper moisture drainage outside the vehicle.
