Maintenance Tips

• Replace MERV-13 filter every 3–6 months – A clogged filter reduces airflow, dehumidification capacity, and energy efficiency.
• Keep proper clearance (≈12–15 inches minimum) – Ensure return and supply air paths are not blocked for rated airflow and ventilation performance.
• Inspect and clean air filter door & intake area – Prevent dust buildup that can strain blower performance and reduce efficiency.
• Check drain line regularly – Ensure continuous, gravity-sloped drainage to prevent water backup, leaks, or shutdowns.
• Maintain correct duct connections – Verify 8” fresh air duct and supply/return ducting are secure and not leaking.
• Verify humidistat/control settings – Keep RH setpoint properly calibrated for stable whole-home humidity control.
• Keep unit level and vibration-free – Helps maintain proper drainage and reduces mechanical wear.
• Inspect coils annually – Remove dust buildup to maintain heat exchange efficiency and prevent icing issues.
• Check ventilation airflow performance – Ensure fresh air intake is not restricted and dampers operate correctly.
• Schedule yearly professional service – Recommended for blower, electrical, and refrigeration system inspection for long-term reliability.
