Pictured above: A 1985 Trane System found in Navarre Florida. Outdoor unit is on South Side of home in full exposure to the elements has no shade at any time of day and less than half a mile away from the Gulf of Mexico. Owner is requesting replacement because he wants to use the property as rental income. The system works fine and according to owner “has never had any major repairs.” This system, being 33 years old and only ever having minor repairs done, is a testament to the superior engineering of Trane products.
Over the years, there have been additions to the home, the duct system is heavily deteriorated, and the attic insulation is almost nonexistent. Currently, the system is off as wiring for the compressor and outdoor fan show deterioration from the weather and elements, but the system was turned on long enough to check operation. No gauges were connected, but there was an 18-degree differential measured between return and supply air.
