We bought a Carrier Air Conditioning/Heating unit and had it installed by a certified Carrier Installer on 7/3/06. Within one year we had to have it serviced 3 times to no avail. We had to fire the original Carrier Installer due to incompetency and contacted the Carrier Corporation when another installer found multiple problems. Because the certified Carrier Installer did not install the unit properly, there was acid throughout the pipes and we had to totally replace the outside and inside unit. We want to bring legal action against the Installer and the Corporation. Would a lemon law apply to this?
