Performed full tune-up on both systems; units left operating. • Filtration/IAQ: Home uses thin return filters that do not seal/capture well → heavy dust buildup observed at blower motor and plenum (photos taken). Reduced filtration is impacting indoor air quality and efficiency. • Condensate Safety: No drain (wet) switch on primary drain line; risk of overflow/leak and water damage if line clogs. Recommendations 1. Upgrade to proper high-efficiency, correct-size filters (tight seal) to protect blower/coil and improve IAQ. 2. Install drain safety switch on condensate line to shut system off on overflow and prevent water damage. 3. Optional: enroll in membership (20% off and annual inspections) to keep maintenance costs low and prevent future issues. Homeowner Decision • Homeowner will think about the recommendations (filter upgrade, drain switch, membership) and follow up.
