I installed a 2.5 ton unit and removed this 2 ton unit it was a little undersized for the house after i added a couple runouts.The unit works flawlessly. It has a 10kw heat strip installed. The unit is either a 2009 or a 2010 model. It has been serviced and cleaned yearly since I bought the house in 2020. I will take 400.00 for the unit OBO. Can provide pictures if anyone is interested. Southern middle TN area.
