Coster Heating & Air Conditioning, Inc has earned 140 five-star reviews from homeowners across Seneca, South Carolina, and surrounding communities. This locally operated HVAC contractor maintains a perfect 5.0 rating, reflecting consistent delivery of heating and cooling solutions that meet homeowner expectations for comfort and reliability. The company operates Monday through Friday from 8 AM to 4 PM, providing scheduled service appointments for residential heating and cooling needs in the Seneca metro area and nearby neighborhoods.

What distinguishes Coster Heating & Air Conditioning from other contractors in the region is their documented expertise with mini-split systems, a specialized ductless technology that several reviewers specifically sought out before discovering this company. Multiple customers noted difficulty finding contractors who service mini-splits, then found Coster capable of handling installations, repairs, and system expansions. Reviewers also mentioned receiving multiple equipment options during consultations, with the technician discussing energy efficiency improvements alongside standard installations. This combination of niche skill development and transparent customer communication appears throughout their review history.

Named technicians appear throughout the review narrative, with Tyler credited for diagnosing and repairing a heat pump that now runs perfectly for one homeowner. Another reviewer described Daniel and Scott installing a heat pump, two returns, an air handler, and a mini-split for a sun room, with the crew covering everything needed and ensuring the system delivered sufficient heating on coldest days and cooling during summer peaks. These specific scenarios illustrate the hands-on approach customers describe when recommending the contractor.
