Carolina Air Conditioning Co. Inc. is a full-service heating and air conditioning company specializing in Residential and Commercial sales, service and installation of HVAC units in Raleigh/Durham, NC. Our HVAC business has operated in the Raleigh, North Carolina area since 1947, focusing on reducing our customer’s heating and air costs by increasing their equipment’s efficiency. Heating and cooling systems require more energy than any other home appliance, which is why it is important to use an HVAC contractor you can trust and engage in preventative maintenance. In 2017 we expanded and moved into our brand new office facilities located at 105 International Drive in Morrisville, North Carolina.
