I'm looking into replacing my 20 year old gas furnace and would appreciate your advice. I live in Seattle in a 1 1/2 story brick house with mostly finished basement. There is no A/C.
I've been checking humidity recently- it reads 60-75% throughout the house. (Did not measure during winter/spring when basement smelled really moldy. Currently there is only a very faint "off" smell.)
I have gotten proposals from several HVAC contractors. They propose either Lennox G71 or Trane XC95.
During times when heat is not needed, will running either of these furnaces in fan-only mode help with humidity?
I was told that the Trane XC95 can be programmed to run the fan intermittently. (This is why it was recommended over the XV95 model.)
One of the Lennox dealers recommended running the fan 24/7.
Or is it better to look into portable dehumidifiers or other solutions?
Thanks for your help on this question and a previous post. (I was unable to post a followup.)
