Josh Cornett (Owner) has made several attempts unsuccessfully with Trane support personnel to remedy a contaminated HVAC Air Conditioning system, due to the system not being installed correctly by a local Trane dealer in about 2018. This situation is in no way a reflection of the competency of Cornett Heating and Cooling. Trane does not appear to stand behind its products and offers no support to non Trane HVAC personnel.

Danny, Will and the team were great in reworking some ducts after a construction project. Their innovative solution kept drywall work to a minimum and significantly improved air flow. Price was reasonable for the two efforts. We will definitely hire them again!
