ABC Cooling & Heating LLC

ABC Cooling & Heating LLC operates as a heating contractor serving Dundalk, Maryland and the surrounding Baltimore metropolitan area, including Catonsville and Gwynn Oak. The company maintains 24-hour availability seven days a week and has accumulated 254 client reviews averaging 4.7 stars, reflecting consistent service quality across residential and light commercial projects. The business is owner-operated, with Mike at the helm as the primary service technician and point of contact for customers.

What distinguishes ABC Cooling & Heating from larger competitors is their direct-owner model, which allows for personalized service without corporate overhead. The company handles emergency situations with same-day response capability, a feature several reviewers specifically praised. Their service menu covers the full spectrum of residential climate control, from heat pump diagnostics to furnace control board replacements, and they source equipment from major manufacturers including Ruud/Rheem systems.

Customer reviews reveal specific scenarios that illustrate their service approach. When Sherry Mason's furnace failed on a Saturday night, Mike arrived within an hour. For Geoffrey Ravenhill, who reached out via Facebook messenger on a Sunday morning, the team installed a complete new HVAC system by that afternoon. Their diagnostic skill also drew praise, multiple reviewers noted that ABC solved problems previous contractors could not identify, and technician Mike was described as knowledgeable, upfront, and respectful of customers' homes.
