SG inc.

SG Heating & Cooling, Inc. operates as a licensed HVAC contractor serving Elkridge, Columbia, and the greater Baltimore metro area with a perfect 5.0-star rating across 36 client reviews. The company maintains three valid credential numbers: NATE certification #3478360 alongside Maryland HVAC licenses #87065 and #55590. Their standard service window runs Monday through Friday from 8 AM to 4 PM, accommodating routine appointments for installations, repairs, and preventive maintenance across both residential and light commercial properties.

This contractor distinction stems from a documented service approach emphasized across multiple reviews: a same-day response capability paired with transparent pricing. The company handles varied equipment brands including Goodman systems and has demonstrated competency across multiple HVAC system types, from standard condensing units to advanced heat pump configurations. Unlike contractors relying on generic guarantees, their recurring review mentions fair pricing and project flexibility to accommodate homeowner budget considerations defines their market position.

Client testimonials present two distinct service scenarios validating their reputation. One reviewer describes Ivan's team arriving on Sunday following a Saturday service call, characterizing the visit as honest, timely, and fairly priced. Another scenario involves Dan, who performed a diagnostic on a non-responsive outside condenser unit, identifying a defective contactor and completing troubleshooting within a single scheduled appointment. A third detailed account describes a complete HVAC replacement completed in just hours, with explicit mention of the technician removing footwear before entering the home.
