I examined the unit inside and out from cleanliness to visual mechanical issues. I spoke with the realtor about the issues with the system. The system needs a full cleaning inside and outside, the blower motor isn’t far from going out due to no maintenance being done, the system needs to be sealed because of air leaks, the outdoor unit needs to be leveled because it is damaging the compressor, and the PVC drain needs to be insulated to prevent the growth formations. I provided solutions to address all of the issues to get the system into the best possible state it can be in and for system replacement. The system is a 2009 gas system. Closet door is 19 1/4” by 68 3/4.
