Client had another company replaced their system a couple of months ago. Client was having nothing but problems with the system and is having old company remove unit and having us replace it with a 2 1/2 ton Carrier heat pump system. Inspected ductwork in attic and advised client that ductwork should be replaced along with the proper IAQ. There is biological growth buildup in ductwork, along with some air leakage. Ductwork is most likely original to when the house was built. Client just wants to replace system for now and possibly do the ductwork six months to a year down the road. Scheduled install for Friday, June 13. Client finance full amount.
