Just want to make sure I cover all bases when getting a system replacement. we are getting an electric, 4 ton straight cool, with furnace and air handler for about 1800 sq ft in the mid south. we nixed the heat pump due to the fact that it would run more and we are more concerned about life of unit than energy costs. electric bills average $120/mo. contractor will pull permits and replace wiring, pressure test line set, inspect ducts, install new silicone sealed return/outflow plenum boxes and add a return vent in loft area. total price is$6600 for trane xr13 with variable speed airhandler.
we are debating xb vs xr and 13 vs 14 seer. is the variable speed handler a more (cost)effective way to increase net seer over the nearly $1000 price jump of 13-14 seer?
thanks for all your input in advance. this forum has been a great help during the process!
