Service

HVAC Condensate Drain Cleaning

A clogged AC drain turns humidity into a water-damage claim

Bottom line

Accessible entry point; validate local supply before buying.

HVAC condensate drain cleaning services clear slime, algae, scale, and blockages from commercial air-conditioning drain lines for offices, apartments, clinics, retail stores, schools, and light industrial buildings. The surprising angle is liability: a cheap blocked drain can leak into ceilings, inventory, tenant spaces, electrical equipment, or mold-prone walls.

How It Works

Technicians visit before and during cooling season, open air-handler access, vacuum or pressure-clear drain lines, clean pans, treat biological growth, test float switches, inspect condensate pumps, photograph condition, and leave maintenance logs. Revenue comes from seasonal PM routes, emergency overflow calls, pan-treatment programs, pump replacement, and HVAC service referrals.
