A Mineola, TX homeowner contacted Family Air HVAC Services for spring air conditioning maintenance. Our technician performed a thorough inspection of the entire cooling system. During the inspection, we discovered two issues affecting system performance. The refrigerant level was 20% below the recommended amount, which reduced cooling efficiency. We also found the return plenum had accumulated significant dirt and debris. After explaining these findings to the customer, they approved both repairs. We added refrigerant to restore proper levels and cleaned the return plenum completely. The air conditioning system now operates at full efficiency and is ready for the upcoming cooling season.
