What happened
Not every visit is a rescue. This BI-series unit was healthy — the owner simply wanted it kept that way. We inspected the system, cleaned the condenser coils and replaced both the air and water filters.
Condenser maintenance is the single best predictor of sealed-system longevity on these units: a clean coil keeps compressor temperatures down for a few dollars a year.
