Claim This BusinessOld School Heating & Cooling LLC operates from Claymont, Delaware, delivering residential heating and cooling services throughout New Castle County. With a 4.9-star rating across 170 client reviews, the company has built a reputation for honest assessments and fair pricing. The family-owned contractor maintains standard business hours seven days a week, from 8 AM to 6 PM, ensuring accessibility for homeowners managing scheduling around work commitments.
What distinguishes Old School Heating & Cooling from competing contractors is their commitment to comprehensive installation work that extends beyond basic HVAC replacement. Reviewers note the crew handled complete gas piping installations throughout homes and addressed structural surprises, like repairing a broken basement step, without additional charges. The company provides courtesy air filters to clients experiencing delays from utility company approvals, demonstrating customer-first thinking that larger operations often overlook.
Customer stories from verified reviews reveal the hands-on expertise driving the company's reputation. Technician Jason arrived at a homeowner's property within one hour of a Sunday call, systematically diagnosing a dual-issue heating problem and walking the client through new thermostat setup. For a full system replacement project, technicians Jason and Bill managed complete heater and air conditioning installation alongside new gas line routing, demonstrating versatility that eliminates the need for multiple contractor coordination.
170 reviews yield a 4.9-star average with consistent praise for same-day emergency response, honest pricing, and thorough diagnostics. Multiple five-star reviews specifically name technicians Jason and Bill, while the single one-star review cites service area limitations rather than workmanship quality.
