Condensing Furnace questions
Hi all it's been awhile. Being out of my field (scorched air) I have some questions concerning a customer of mine.
I was there and he had expressed interest in converting to LP from oil. He has just purchaced this house and the oil tank is ruptured. They are doing a Reno and out are coming the Bock, and Airco FHA oil fired units.
He has had three quotes for the furnaces (I am there installing a Rinnai Tankless.....tried to talk himout of it). Two quotes were for York 120Mbtu single stage, and one was for a two stage. I thought that seemed way oversized and did a heatloss, came out to 74Mbtu and some change. I told him based on my expierence to get nothing more than an 80Mbtu unit. I am not sure if he should get a modulating unit or the two stage would be sufficient. FHA is not my specialty, hate it actually, I am a wethead through and through.
Are there good ones, and are the modulating ones worth the extra $2k?
Thank you for the collective wisdom.
