Why AC Blowing Warm Air Happens in Palm Harbor

In Palm Harbor, the unique climate and environmental factors contribute to the frequency of AC units blowing warm air. The proximity to the Gulf of Mexico creates high humidity levels, which can strain your air conditioning system. Many homes in the area are older and may have outdated HVAC units that are more susceptible to wear and tear. Additionally, debris from the area's mature oak trees can obstruct outdoor units, leading to mechanical failure. Homes near Lake Tarpon may face different humidity patterns, further complicating the performance of HVAC systems in those locations.
