Recommended service intervals for Lenoir City Mini Splits

Proper timing keeps performance consistent through seasonal extremes. These are industry-recommended intervals adapted to Lenoir City conditions:

• Filters: Check monthly; replace washable filters every 3 months if heavily used, or monthly during high pollen and humidity seasons. Replace disposable filters according to manufacturer guidance.
• Basic service Tune-Up: Twice per year, ideally in early spring before heavy cooling season and in late fall before winter heating is needed.
• Coil cleaning: Annually, or more frequently if the system is in a dusty or pet-heavy environment.
• Refrigerant check and leak inspection: Annually; sooner if you notice a drop in capacity or increases in run time and energy use.
• Drain line inspection and cleaning: Annually, with a follow-up after high-pollen seasons or heavy fall leaf drop.
• Electrical component inspection: Annually to catch early signs of wear caused by heat, humidity, and seasonal cycling.
• Full performance test with airflow and refrigerant diagnostics: Annually during one of the biannual Tune-Ups.

Adhering to this schedule reduces the risk of midseason failures and preserves energy efficiency year over year.
