Heating and cooling unit needs to be replaced you were quoted from rheem rgpn05eauer rheem 2 ton 13 seer condenser 13ajl024 and rheem 2 ton 13 seer cooling coil rcfl-h-2414 for 5000 fair?

This equipment is all builders grade stuff. I have attached a link to the spec sheet for equivalent RUUD condensing units ( made by RHEEM ), just substitute the U in the model # with an R to get the Rheem equivalent.

This past May I bought a UGPR07 furnace (two stage & VS fan) with a UAPL030 (14 SEER) condenser and an RCFL-HM-3617coil for $5600. So you are in the ballpark pricewise but you may be able to get better equipment for a little more $.
