I am replacing a gas furnace and am also considering a hp install at the same time and I have several questions. A Carrier salesman said that I could expect the hp to supply my heating and cooling needs for about 310 days a year. He also suggested a 58MVB080 - 14 Infinity 96 and a 25 HNA6 - 036 Infinity 16 with the Infinity control would be a good fit. For the background info. I live on the " Wet " coast in a 20 yr. old 3300 sq. ft. house with a slab on grade for first floor. The original furnace is a Lennox approx. 100,000 btu. located on the main floor.
1) Is there some way of determining the condition/quality of the ducting short of tearing the ceiling down? ( All of the ductwork is located on the main floor and is covered by a finished ceiling.) Because we don't have extreme temp. here I was hoping a hp could be sized on the smaller side because of the expected duct size restriction. Is this reasonable?
2) What should I be looking for if I want to optimize humidity control, ideally at approx. 45% ( to limit the affects of dust mites )
3) I also would like to know if a American Standard Accuclean air cleaner(I believe this identical to the Trane CleanEffects) can be installed with the Carrier system wo any conflicts? (ie. the infinity stat. ect.) I am very concerned about the IAQ because of my children having asthma and allergies to various pollens and myself being diagnosed with an industrially aqquired lung disease.
4) How far can the hp be located from the furnace before more Puron must be added. ( length of run is approx. 55 to 60 ft.). And does the copper piping need to be jacketed or covered some how if it is run across the home through a dropped ceiling?
5) Given how vital a quality install is to a properly functioning system, is it reasonable to expect my old furnace can be removed and the hp, new furnace, air cleaner and the electrical and new duct to tie in can all be done in one day by one tech. ( the electrical pnl. is within 5 ft. of furnace and easily accessible.)
Any and all responses appreciated.
Thank in advance.
