Avoid in Kendall
- Closing registers in unused rooms — increases static pressure and stresses the blower.
- DIY condensate-line vinegar treatments more than once a quarter — vinegar is mildly corrosive over time.
- Pressure-washing the outside condenser without rinsing properly — soap residue attracts dust.
- Skipping attic insulation inspection — settled or compressed insulation around duct boots wastes 20%+ of cooling.
