Performed diagnostic on 2011 Goodman heat pump system. The system conditions, the upstairs portion of the home. This is a 3 ton system. Home is currently for sale and being shown today.Upon initial inspection found pan to have an inch of water in it. Upon startup of AC pressure in system is extremely low around 50/260. This is one of two things. This system has either developed a significant leak. Or the system is no longer flowing refrigerant properly and has a clogged piston or line dryer. Neither the situations are good. With the age and condition of equipment. This repair is not really recommended. There are other things going on in the system as well. The contactor is buzzing loudly and close to failure. The blower capacitor is out of spec and should be replaced. The blower assembly is very dirty. This system is running without a filter currently. This looks to be a 25 x 25 or 30 x 30 filter in the wall. Simply not in place. There is visible ice on the coil currently. I will quote
