What size furnace do I need? 60,000 BTUH or 80,000 BTUH?

[SkyHeating]

It should be any model that is a TH832
The 8 denotes its a vision pro and the 32 denotes 3 heat and 2 cool in most cases so that would give you a good start.

Skip the 8110, being a 1 stage. The 8320/802 or the Vision Pro WiFi if you want remote access are 2 stage.

I consistently have been recommended the Honeywell VisionPro 8000. Is that the kind of thermostat you are referring to?

I do have an electronic air filter, that the same thing as a media filter cabinet?

Electronic IS NOT the same as MEDIA filter.

Electronic air filter needs to be cleaned 16 times a year.

5" media filter only needs one light vacuum at six months.
Change yearly.
