Completed with heat 1 on a 2009 carrier heat pump 3.5 ton horizontal in attic, found heat strips trying to come on but won't come on, very rusted evaporator coil which can start leaking refrigerant at any time, unit very short on return needing additional 14 inch, compresor starting pulling 16 amps then went all way to 20 and went off, with a weak capacitor rated 45/5 reading 39/4 and no compressor saver. Giving customer the option to do all preventative repairs, minimum repairs or complete unit upgrade. Wife needs to talk to husband before making any decision.
