About Advanced Technology LLC.
Advanced Technology LLC serves residential and light commercial clients throughout Columbia, South Carolina, and surrounding communities. The contractor holds a 5.0-star average across nine verified client reviews, reflecting consistent service delivery in heating, ventilation, and air conditioning repair, maintenance, and installation work. Business contact information includes phone (803) 629-7370 and web domain at-hvac.com.
Unlike contractors who default to major component replacements, this team prioritizes precise diagnostics before proposing solutions. Reviewers specifically note honest assessments that avoid unnecessary upsells, with one client describing how a competing company quoted thousands for work this team completed with a minor adjustment. Transparent communication and fair pricing distinguish their service model.
Clients consistently name Bailey and James as the technicians delivering their service. One Columbia homeowner recounts Bailey identifying a thermostat wiring fault in ten minutes, a problem two prior contractors overlooked while quoting extensive repairs. Another reviewer describes texting about a failed water heater and receiving same-day assessment, with the technician arriving within an hour and resolving the issue that same afternoon.
