The Technician Alan Hixon, was very friendly and polite. He explained about how the different filters worked and let me know the condition of my heat pump. Also, explained in detail the difference between the heat pump and the emergency heat.
Henry Stevenson checked the YORK outside unit, the motor had gone out. He replaced the condenser motor on capacitor and we turned the A/C on and it worked! Thanks to him, I don't have to buy a new unit!
