Downstairs HVAC System

[Gus-Herb94]

This is the downstairs furnace in my house, an Armstrong "Ultra 80" it's original to the house from 1990, I just have a video of it right now but I will take pics of the whole system later. Anyway the reason I'm posting this in the WOP is cuz It's been in excellent working order for some time now after I fixed everything, it's sized almost dead on to the heat loss of the house (just off by 2,000 btu's) it is controlled by a Honeywell Vision-Pro thermostat which I installed in 2007 and together they keep the downstairs very comfortable in the winter. The furnace has had all of it's faulty early design electronic components replaced so no more reliability issues. The duct work is all sheet metal. That's all I can think of about the furnace right now but I will talk about the cooling side of the system (which works excellently too) when I post the pics later (big story about the A/C!)

Ok I finally got pics of the downstairs system, and once again the reason I'm posting these on the WOP is not cuz of the appearance of the installation but cuz of the fact that I got everything tuned to the optimal efficiency and comfort level + of course all the ductwork is balanced to the proper air flow per room, and this system does keep us very comfortable Summer and Winter.

The first pic is of the 19 year old Armstrong furnace and surrounding ductwork, It's 80% efficient and it's heat output is 80,000 btu's, only 2,000 btu's more than the house's heat loss calc calls for.

Second is a pic of the Ductwork with my back facing the front of the furnace.

Third is once again of the Ductwork at the far end of the basement showing a few of the branches.

Fourth is of the Ductwork coming from the backside of the furnace going into the crawlspace and serving the family room and two guest bedrooms.

Fifth is of the Condenser, it serves the whole downstairs level of the house that is 1800 sqft with tons of all day long sun exposure and many south and west facing windows, it's 2.5 tons in capacity it is also 19 years old and 9 seer (I know not good). After I got everything balanced out properly it will keep the house at 70 degrees all afternoon long on a full-sun day at up to 93 degrees outdoors, it normally keeps the humidity level at about 42% and when it's hot and super muggy out it will always keep the humidity below 50%.

Last is of the Honeywell Vision-Pro, I installed that in July 07. And no I don't normally have it in "Hold" mode! The downstairs A/C hasn't been needed that much so I have it "Held" at above the normal setting.


So I said there was a big story about the downstairs Condenser...The story is that it didn't work for the first 11 years of it's life because when it was first installed the freon lines were never brazed properly and my parents didn't even turn it on for the first 4 years so when they did it ran and ran and ran with no freon until the compressor burned up, and then in 1999 the same Dumb$#@ installers came and replaced the compressor but they never even "sanitized" the system so to speak after the burnout, and it never worked right afterwords and the refrigerant still was leaking out like mad. Then finally 2 years later in 2001 they finally called a competent and reputable company to come and diagnose everything and he found clogged capillary tubes in the evap (big surprise!) So the evap was replaced and it's been working well since 2001 except for a couple times the lineset sprung a leak at the condenser and was repaired.

So that concludes the loong history of this system Please feel free to leave any comments or questions.

Hey it's old, but like I said it really functions well for it's age.


If the mods really think it's that bad looking they can move it to the WOS.....but that would be age discrimination then

Purple wall???

I guess it looks alot different in photos. That's the dining room wall and it's actually pink.

I guess you guys got the wrong idea, its not a girly pink at all it's more of a classy antique pink that goes with traditonal decor. But whatever think what you wanna think I don't care.

I made a video today of the downstairs A/C running while it was 88 degrees out and 67% humidity (Steamy!) the indoor humidity was 42% and 72 degrees...
