- Warren County and Lincoln County furnace service. Homes in Warrenton, Wright City, Troy, and rural Lincoln County often have older furnaces and rely on propane systems not common in urban areas. AAA's HVAC team is experienced with the full range of systems found throughout this region.
- Non-commissioned technicians. Unlike many home service companies, AAA technicians do not work on commission. They don't earn more by recommending a replacement so when they say repair is the right call, it is.
- Carbon monoxide safety.
AAA includes a heat exchanger inspection with every furnace service call on systems over 10 years old. In rural Wentzville-area homes that sometimes go longer between service calls, this check is especially important.
