Great Mills Heating & Air Conditioning anchors its reputation in Lexington Park and the broader St. Mary s County region, earning a 4.9-star rating across 99 verified reviews. This locally established contractor operates Monday through Friday from 7:30 AM to 4:30 PM, delivering heating and cooling solutions to homeowners throughout Southern Maryland. The company has accumulated substantial feedback from the community, with customers consistently noting professional conduct, adherence to projected timelines, and competitive pricing on both routine maintenance and system replacements.

What distinguishes Great Mills from neighboring HVAC providers is their transparent pricing methodology and investment in high-efficiency equipment OPTIONS.

Customer narratives reveal consistent themes across service experiences. Adam Johnston described a same-day adjustment visit within weeks of a new high-efficiency Amana installation, while Kathryn Jencso noted her fourth-year satisfaction with both water heater and HVAC equipment installed by the crew. Ramon Badia chronicled a 25-year relationship with the company, emphasizing their ability to complete a recent gas furnace replacement ahead of insurance-processed alternatives.
