Alliance Plumbing & Heating - Rockland's Experienced HVAC Services

A comprehensive plumbing inspection checks your home's entire drainage system, including the condensate drain line from your HVAC unit. In our damp Rockland climate, this line can easily clog with algae or mold, causing the drain pan to overflow. This excess moisture can freeze on the outdoor unit in winter, leading to ice buildup and potential system failure. Our inspection identifies and clears these clogs proactively, protecting your HVAC system.

If you notice ice on your outdoor unit, first turn the system to 'OFF' at the thermostat to allow it to thaw completely. Do not chip at the ice, as this can damage the delicate fins. This ice often signals an underlying issue like a clogged condensate drain or low refrigerant. Contact Alliance Plumbing & Heating for a professional assessment. We'll safely thaw the unit, diagnose the root cause—common in our Rockland winters—and perform the necessary repair to prevent recurrence.

Our humid coastal air in Rockland and the Midcoast creates an ideal environment for algae and microbial growth inside the condensate drain line. This line removes moisture extracted from your home's air by the AC or furnace. When it clogs, water can back up, causing indoor leaks, humidity issues, or system shutdowns. During our plumbing inspections, we specifically check and flush these lines to prevent clogs, a key preventative step for local HVAC system health.
