Signs Your AC Needs a Professional Look

Not sure if it is time to call a professional? Watch for warm air from the vents, strange grinding or squealing noises, weak or uneven airflow, higher than normal energy bills, water pooling near the indoor unit, or a system that will not turn on at all. Catching these signs early keeps a small AC issue from turning into a costly, uncomfortable breakdown in the middle of summer.
