Maranto Refrigeration HVAC: Professional HVAC Repair Serving Lake City, FL 32055

Uneven cooling is a common issue in our area, often caused by ductwork problems, an undersized unit, or a failing component. Our technicians perform a comprehensive system evaluation, checking airflow, duct integrity, and refrigerant levels to diagnose the root cause. We then provide targeted repairs or adjustments, like sealing ducts or rebalancing the system, to ensure consistent comfort in every room of your home.

Yes, a stuck or faulty reversing valve is a frequent culprit for heat pumps in Lake City that won't change modes. This valve directs refrigerant flow for heating or cooling. Our expert diagnosis can confirm if the valve is the issue. We'll check for electrical problems first, but if the valve itself has failed, we can perform a precise replacement to restore your system's full heating and cooling functionality efficiently.

Proactive maintenance is key. We recommend bi-annual tune-ups before peak heating and cooling seasons. Our service includes cleaning coils, checking refrigerant charge, inspecting electrical components, and testing the reversing valve and other critical parts. This helps catch small issues early, improves efficiency to combat our humidity, and extends the life of your system, saving you from unexpected breakdowns and costly repairs.
