Great Bay Air Conditioning & Heating | Top-Rated HVAC Repair in Largo, FL

Signs of mold in ducts include a musty odor when the system runs, visible growth around vents, or increased allergy symptoms at home. For Largo homes, our humid climate makes this a common issue. Great Bay performs a detailed inspection and offers professional duct cleaning and sanitization to remove mold spores and contaminants, improving your indoor air quality and system efficiency.

Reduced cooling, ice on coils, and hissing sounds often indicate a refrigerant leak. This is a frequent problem we see in Largo. Great Bay's technicians use advanced leak detection tools to precisely locate the source. We then repair the leak, evacuate the system, and recharge it with the correct, EPA-approved refrigerant amount to restore optimal performance and efficiency, preventing further damage.

We recommend bi-annual maintenance—once before summer and once before our mild winter. Our thorough check-up includes cleaning coils and drain lines to prevent mold-friendly moisture, checking refrigerant levels and connections for leaks, inspecting ductwork for integrity, and ensuring all components are working efficiently. This proactive service helps prevent the most common local HVAC problems, saving you money on repairs and energy bills.
