Avoid in Coconut Grove
- Tearing out original ductwork without inspecting attic structural integrity first — Grove rafters often need reinforcement before equipment swaps.
- Sealing crawlspace vents without a moisture mitigation plan — you'll trap humidity instead of removing it.
- Cheap fiberglass-batt repairs to attic duct insulation — fibers shed into supply air. Use closed-cell wraps.
- Skipping the dryer-vent termination check — bird's nests in roof caps are the #1 cause of dryer fires we find here.
