I had my HVAC out to look at my heat pump yesterday and I have a few questions. First he told me I have a leak someplace on my indoor (6 y/o York) unit that would most likely requiring the entire inside unit to be replaced for about $. Are leaks in the coil not repairable? He then told me that a new indoor unit would only have a 1 year warranty and that with the cost of a new fan and cap, indoor coil, and refrigerant that I'd be better off spending $ on a new system with a 5 year warranty. The guy seemed pretty honest but I just want to double check. I was also told that my outside unit needs a new condensor fan motor. He also told me as far as just replacing the fan and the cap that it is something that could be done by me to save the some $ that he would have to charge.the fan is an Emerson 1/4 HP 208/230 850rpm 48y. I can't seem to find an exact replacement. I keep finding motors that match all except the rpm 825 is easier to find than 850. Is it OK to use an 825 rpm motor? The 825s are also cheaper than the only 850 I could find by about $. My original reason for calling was that my condensor fan was not working anymore. He hooked up a voltage meter and determined that the motor was done. Thanks in advance for your help.
