It took 65 seconds for my furnace to use one cubic foot of gas. Which equals 55 cubic feet per hour. Which equals 52061 btu/hr. Pretty close to the name plate input rating of the furnace.
On low fire, which is where I have it locked for the fall, its 52K input. That's 55.3 cfh. Its getting cold enough for me to actually clock it.
I will agree that I'm probably not getting 96.6% efficiency. That's why carrier stated "up to" 96.6% efficient. But the lower flue temperature proves more of the BTU's are remaining in my home.....
Placing my hand on the pvc flue would immediately inform me that my 96.6% is more efficient than my old 80% furnace without any calculations because I wouldn't have a blister. No?
The 58MVP is "up...
I installed a new carrier 58MVP 75K furnace. It kept locking out so the outfit which sold it to me instructed to have the gas pressure checked. When Mid-America checked the pressure, they also...

Thanks Teddy. Quite honestly. Every so called professional Iv invited into my home was a joke.

Yea Im not worried about cost. You usually get what you pay for.
Can you recommend a stat which has a outdoor sensor which locks out W2 and is user friendly before I start searching?
I tore out a 120K and replaced it with 75K. 4 ton down to 2.5 condenser, 3 ton coil. 2600 square feet 70's 2x4 construction. I winged it.. No manual J
I like that idea about a outdoor stat...
Yup, found the switch now.. SW-2 needs to be on for two stage. Thanks dunkman.
My home is a split foyer/level home with a louver door on the furnace room. When high heat kicks in, it sounds...
Please correct me if Im wrong..

I'm trying to find a new thermostat for my carrier 58MVP furnace to replace my single stage Honeywell T87. The 90%+ Furnace has variable speed blowers and 2 stage heat. I under sized my A/C to...
I think we are talking about the same thing except for the hinge location. The 16 gage was only a thought because I know it will want to flop around with the amount of air passing by it.
I guess I still dont see a leaf damper in there. Im just going with the images I find when I goggle leaf damper and splitter damper.
Heres my first attempt with sketchup

I know you didnt have this option. But ground source heat pumps or geothermal heat pumps rock.
One of the best ones IMO..
Heres a pic. Its a typical residential install. I did raise the coil so I could see it from the bottom. 18x8 taken off the front and 14x8 off the back. I need to completely block...
