Coil Cleaning in Orlando, FL

What a dirty evaporator coil actually costs you

A loaded coil ices over. The ice melts faster than the pan drains. Then water finds attic drywall. Many air handlers sitting on attic platforms in 1970s–90s homes have a secondary pan but no working float switch. Starved airflow also drops suction pressure, and liquid refrigerant heads back toward the compressor. That repair is in a different class than a cleaning.

The dirt arrives from predictable places here. Builder-grade 1-inch filters bypass at the rack, so air slips around the media instead of through it. Return plenums pull unfiltered attic air through unsealed framed chases. Older bare or internally lined rigid metal in pre-1970 houses sheds fiber fragments onto the coil face. Post-renovation drywall dust blinds a slab fast. So does flex duct sagging between trusses, holding debris until a cycle lifts it.

Cleaning happens from the return side. Spraying the supply face packs the mat deeper into the slab. Access often means opening a panel that was foamed shut at install. Foaming cleaner, dwell, rinse, then the pan and trap get flushed afterward, not before. Fins get combed. Acidic condenser products stay outside.

Honest limit: if the end plate is rusted through, or the duct still sheds fiberglass, a clean coil reloads quickly.
