I live in Philadelphia and have a dual-fuel Lennox XP21 HP/SLP98 furnace and iComfort controller. What is the recommended setting for the Defrost Termination Temp so as to not "over defrost" but also making sure it clears all the ice off the coils? The iComfort does not have defrost tempering but I can live with the 2-3 mins of cold air during defrost. It has a setting for 50-100* and I currently set it to 60*. The default is 50* and I feel it does not clear all the ice when it gets real cold outside. My intention is to run the HP down to as low an outdoor temp as possible. HP Balance point temp is set at 30* and Aux heat lock-out is set at 20* since I have expensive propane. So far, the furnace has not kicked on even around 27*.
I'd want at least 70.
I no longer use my humidifier on my gas furnace can I take it off and plug the holes into the duct work?

I recently purchased a home built in the early 1950's. It has a forced air oil furnace. I noticed that most of the basement duct work is new with the exception of the runs going up in the wall that service the first and second floor. These ducts are wrapped with the same substance. I have fears of what it might be - asbestos. What are your thoughts? I plan on having a sample tested later this week and am bracing for the massive expense of removal. Somehow the home inspector missed this.
It may be asbestos and probably is.
Don't panic as apparently if it is painted with oil based paint and encapsulated then the fibers cannot get out and it is safe. Do some research about that and I am sure latex is not good enough.
Duct cleaning companies remove it and they spray it with water when they are working with it. Once again there are no loose fibers. Not super expensive and you may want to research that.
Doing large amounts of asbestos removal in buildings is different as they have to create isolation areas and have a negative pressure but for small amounts it may not require as elaborate a process.
