On 8/23/2019, I paid $5, 280.00 to Heaven's Breeze A/C P.O. Box 272442, Tampa, FL [protected]. A Trane A/C was installed and a heater. In addition I have paid 2 times $75.00 and was told on their last service that a coil was damaged. The coil is still under warranty. Today 7/19/2021 they want to charge me $900.00 to fix this issue. I don't have cool air in my house for the last 3 days when the Ferron stopped working. Since they installed the air conditioner, and the part is under warranty then I should not be liable. Please help.
