I will be pulling the trigger on the purchase and installation of a 60,000 BTU Carrier Infinity 98 modulating furnace (model #59MN7A060V17-14) with a Carrier Infinity 20 Greenspeed heat pump (model #59MN7A060V17-14). The AC coil to be included is model # CNPVP3717ATA. Can you confirm this system is matched well for the highest efficiencies?
My home is a 20 year old two story center hall colonial with total square footage of 2200 square feet (2 x 6 exterior stud walls and insulation). Two thirds of the basement is finished and is on separate electric heat.
I am looking for recommendations/suggestions on an Air Cleaner and humidifier. I am interested in a media filter only and was considering an Aprilaire 2410 or a Carrier media filter such as the Carrier model EZXCAB. Will the Carrier filter box marry up better with the Carrier furnace? I’ve had a Carrier EZXCAB in a previous house and was pleased. Does the Aprilaire offer any advantages over the Carrier EZXCAB?
In regard to a humidifier, given I have a hybrid set up with heat pump heating capability, should I go with a steam humidifier to more effectively introduce moisture to the return air? Can you provide some suggestions as to my best option on a humidifier? I was considering either Carrier or Aprilaire. If a standard bypass humidifier is recommended should it be plumbed with hot water given the heat pump set up? Also, ideally I would like to use the Infinity controller to control my humidifier vs hanging an additional controller on the living room wall. Is infinity control of the humidifier easily achieved?
I have metal ductwork with internal insulation. Should I be mandating sheet metal trunk connections with the unit or is the foil covered insulated duct material acceptable?
Also, is it a big deal to request the furnace be connected to the natural gas line with black iron threaded pipe and a union disconnect vs the yellow trac pipe? My previous house install included a trac pipe hook up which looked sloppy given it seemed a 4 foot piece of trac pipe was used for a 2 ½’ application length.
Sorry to ask so many questions of you professionals, but I’m hoping to get a nice clean and “tight” install. I believe establishing a good understanding on the front end can only help. Your help with this matter is greatly appreciated so I can finalize my contract as soon as possible. My Bryant 90 Plus has a cracked heat exchanger and it is tripping the roll out switch on occasion.
