South of Boston Heating & Cooling | Licensed HVAC Repair in Duxbury, MA

Our humid coastal climate makes condensate drains prone to algae and mold clogs. During a routine maintenance visit, we thoroughly clean and flush the drain line, apply an algaecide tablet, and check the drain pan. This simple, proactive service prevents water backups that can cause costly water damage to your ceilings, walls, or HVAC system itself.

Absolutely. Many Duxbury homes have older ductwork that can develop leaks at seams and joints, drastically reducing airflow and making your system work harder. We perform a detailed inspection, often using specialized tools to locate leaks you can't see. We then permanently seal them with professional-grade mastic or metal-backed tape, restoring efficiency, improving comfort, and lowering your energy bills.

If you're facing frequent clogs or airflow problems due to aging, poorly designed, or undersized ductwork, repeated repairs may not be cost-effective. We'll assess your entire system. If the ductwork is extensively compromised or your unit is over 15 years old, a replacement with a properly sized, modern system and new, sealed ducts is often the best long-term solution for Duxbury's climate, providing superior reliability and efficiency.
