Maintenance Tips

• Replace HVAC Air Filters Every 1–3 Months – Clean filters maintain proper airflow across the all-aluminum evaporator coil, improving cooling efficiency and preventing coil icing.

• Keep the Coil Surface Clean – Dust buildup on aluminum fins reduces heat transfer. Schedule professional coil cleaning annually to maintain performance.

• Inspect the Condensate Drain Pan & Line – Ensure the rust-resistant thermoplastic drain pan and drain lines remain clear to prevent water leaks and microbial growth.

• Check TXV Performance – The factory-installed thermostatic expansion valve regulates refrigerant flow; periodic HVAC service ensures correct superheat and efficient cooling.

• Maintain Proper Airflow Through Ductwork – Keep supply and return vents unobstructed to support consistent airflow through the horizontal A-coil design.

• Inspect the Cabinet & Insulation – The galvanized insulated cabinet reduces condensation; check periodically for moisture, insulation wear, or corrosion.

• Schedule Annual HVAC Maintenance – Professional inspections help detect refrigerant issues, clean internal components, and keep the 1.5-ton R32 system operating efficiently.
