Hey guys,I need a little help on this one. Has to do with matching 13 seer heat pump to 12 seer air handler.
From the begining. Guy's wife works as a property manager
mananging apartments. They replaced a TRANE 12 seer heat pump because of a short cycling compressor. He had his uncle who works in the HVAC field and told him there was nothing wrong with the equipment so his wife was able to get the unit at no charge. His uncle was going to install it in ( my buddy's house) but the uncle kept putting it off so He ask if I could help him out. The uncle also had purchased a Goodman 12 seer a/h for this equipment.
After getting the story on this unit I told him I would by-pass the fore-comming headaches and buy a matching h/p to go with the a/h he had bought. He said since he had both pieces of equipment he would put them in and if it went bad he would change it then. Being my pal, I said I would do what ever he wanted to do.
Once the duct work and a/h was in, line set run began to set the h/p. The system had been pumped done valves cut off and the ref. lines cut and left open. I cleaned out the openings as best I could blew nitrogen through the system before brazing line set in place. Pressure tested with nitrogen pulled deep deep vacuum and charged system.
Worked fine for a day, compressor locked up, electricaly checked out fine replaced potential relay and installed hard start with no luck.
Now this is the real question. What will be the outcome by installing a 13 seer h/p to a 12 seer a/h? I have been told it can be done and the only problem with this type of system will be not having a 13 seer rating.
H/P and a/h is 4 ton plenty of heat and cooling for this house. What about dropping down to 3 or 3.5 ton h/p?
Keep in mind this guy is going to keep the new a/h and just buy new h/p.
ans please no goodman bashing and for what its worth, I think the 13 seer standard is just government propogandy
