RSC Heating & Air Conditioning

For more than 35 years, we have helped homeowners and businesses stay comfortable through every season. From our Lancaster office at 139 Supervisors Road, we serve customers throughout Lancaster, Lebanon, York, Berks, Dauphin, and Chester Counties, including communities such as Hershey, Middletown, Lititz, Oxford, and Denver. Our courteous, knowledgeable team brings extensive experience to residential and commercial heating and cooling systems, with careful attention to detail and thoughtful designs shaped around each customer’s needs.

We install, maintain, and repair a wide range of HVAC equipment, including central air conditioning, ductless AC, heat pumps, furnaces, radiant heating, and geothermal systems. Whether we are completing a seasonal tune-up, diagnosing a system failure, replacing equipment, or planning a new installation, we begin by assessing the space and listening to what the customer needs. We work to develop practical, customized comfort solutions for homes, offices, and other commercial spaces. For commercial heating needs, we provide a detailed analysis of the challenges and recommend solutions suited to the space.

Professionalism and respect guide how we work. Our nationally certified technicians arrive in clearly marked vehicles and company-identified uniforms. During each visit, we take care to keep the work area neat by using drop cloths and protective shoe coverings, bringing our own hand cleaner and towels, and removing trash generated during the job. We also value collaboration within our team: our technicians share knowledge, strengthen their skills, and maintain professional certifications so all of us can provide better service. As a sixteen-time National Award Winner, we are proud of our record of customer service, installation standards, and a team culture built around respect rather than ego or competition.
