A home's HVAC system is essential for comfort and energy efficiency, but over time, wear and tear can affect both performance and safety. During a recent inspection, ASHI-certified inspector Brad G. of LunsPro Inspection Group examined a 1997 Trane XC80 gas-fired furnace—a well-built system that had exceeded its typical 15 to 25-year lifespan.
While still operational, the inspection uncovered a few code and safety concerns worth noting for homeowners.
Common Issues Found in Aging HVAC Systems
1. Missing Drain Pan
- Modern building codes require a drain pan beneath HVAC units to catch condensation.
- Older systems may not have one, increasing the risk of water damage.
- If installing a new furnace, a drain pan should be included to comply with current safety standards.
2. Absence of a Drip Leg on the Gas Line
- A drip leg is a small vertical pipe that captures sediment and debris from the gas line before it enters the furnace.
- Without one, contaminants can clog the system over time.
- While retrofitting older units may not be necessary, new furnace installations should always include a drip leg.
When Should You Replace an Old Furnace?
A well-maintained furnace can exceed its expected lifespan, but signs of deterioration should not be ignored. Homeowners should consider replacement if they notice:
✅ Frequent repairs and rising maintenance costs
✅ Uneven heating or increased energy bills
✅ Strange noises, rust, or visible wear on components
