Signs Your HVAC System Needs Immediate Service

Warning Signs for Your Air Conditioner

Knowing when to call for professional AC repair San Diego can save you from costly breakdowns and extended discomfort. Warm air from vents often indicates a refrigerant leak or compressor failure. Weak airflow typically points to a duct or blower motor issue, while loud noises such as banging or rattling signal internal component wear. Water leaks near the unit suggest a condensate or coil problem, and bad odors can indicate mold growth or an electrical short. Frequent cycling and high energy bills are also common signs that your system is losing efficiency.
