Reuse 1 yr old furnace to attic and match coils to condenser?
Comments (5)You need to get involved with a quality dealer and forget the GC. Dealer needs to follow up on the matching R-22 evap coil from Frigidaire. It seems this is the way to go assuming you have no performance issues with the AC. Do you even know? Third party evap coils are available in the marketplace. I don't care for them but you already have a mismatched system of different brands. If for some reason existing Frigidare condenser can not be used, then I would go for a Bryant 13 SEER condenser with matching coil. You can't go with a 4 ton condenser because your blower motor on the furnace is only rated up to a 3 1/2 ton. As asked previously, you have good access to attic for moving the furnace? What size living space is your home? Dealer will need to extend or replace existing lineset most likely. That's the way to go. Drop the GC on the HVAC aspect of your home's modification. IMO...See Moregas condensing furnace
Comments (3)Its rare for pressure switches to fail unless subjected to water/moisture. Sounds like you are getting it to work by bypassing the blocked intake function of the pressure switch....See MoreRunning condensate drain line on goodman furnace
Comments (49)I thought we agreed that we were not going to limit the discussion to the climate of Katy Texas? Well the OP who started this thread made it sound like he lived near me... which would mean using my climate numbers as opposed to somewhere else. I don't service areas outside my climate so why on earth would I entertain this idea of yours? (I offer advice on occasion but that is all it is --- professional advice --- as this is what I do for a living, I don't sit all day in forum board --- I do have a life outside of HVAC, what little it is right now it's still a life...) You again trying to fit HVAC in a confined specific box in which it does not fit. What are the odds that someone will find that information useful? Probably close to 0% if I had to guess. That sounds like a waste of time... I know this seems productive to you so knock yourself out if you want to do that. Exact numbers are not necessary to educate everyone the source of the condensate. Then why not use the 'about 0.8 gallons estimate' and run with it? An air conditioner in my climate can produce upwards of 5 gallons of water an hour. A condensing furnace will not produce that much. An 80% non condensing furnace will produce 0 condensate water. Oh so let's use the AC condensate line for the furnace condensate. Problem solved right? Most likely not. Drain systems are complex especially when you throw in the variable that a condensing furnace imposes. See I've led your hand to this point --- where the concern right now up to this point is how much more condensate a condensing furnace will produce in my climate Katy, Texas versus other less humid climates in which those furnaces are installed typically in a basement. You don't have the over head flood threat you do here in my climate. All of this --- except: there are safeties on that condensing furnace that if you don't do it properly, the furnace will shut off on nuisance trips. So the furnace is not likely to be the cave in threat due to condensation production. They tend to leak water in drips around the furnace while having very erratic operation most often. You don't get these kinds of problems with a 80% non condensing furnace. What a home owner knows versus that of a pro... you think condensate is the only problem you have to contend with. What is your definition of making this actually work? How does the condensing furnace then become the ceiling cave in threat? Changes to the condensate drain system by people who don't know what they are doing. It may be a home owner, land lord or even a technician who doesn't understand the implications of what they are doing. How much water one produces whether here in this climate in Katy, Texas or a less humid climate (in winter) like Chicago / Wisconsin --- the different in condensate production doesn't matter... *IF* the system to get rid of condensate is adequate. This thread was about a young guy presumably in his 20's attempting to install a condensing furnace in a probable high humid climate. That condensing furnace was bought used. Who in their right mind sells a condensing furnace (used) in a probable high humid climate? One that tried to install said furnace and couldn't get it to work. I have an innate ability to read between the lines. I've seen quite a bit of 'Tom Foolery' in my nearly 26 years of doing this for a living. We can't get it to work so we'll take it out and sell it to someone else. So what makes the condensate drain system of a condensing furnace adequate? The right way. What is the right way? The opposite of wrong. If you want to learn how to do it: There are trade schools for that. Class dismissed.........See MoreWill this condensate pump work with gas (propane) furnaces?
Comments (6)Thank you everyone for the advice and input. The weather here has quickly turned cold, and now I'm in a bit of a pinch to get this new pump hooked up. The current drain line for the pump we have is empty so I'd prefer to install the new unit before turning the furnace on and filling the line with liquid. The pump only needs to lift about 7-8 feet vertical with maybe 25 feet of tube, so probably any pump would work in that regard. Our winters are regularly below freezing for most of the coldest 4 months, so I'm not keen on running the condensate on it's own line outside. I could bury it enough that the cold wouldn't be a problem, but it's already hooked into the the sewage line so it's just much easier to get a neutralizer. I think this time I'm just going to go with my first thought and get this Saniflo 2-in-1 unit, mainly for ease of install because it looks like it will fit right under the current furnace drain pipe and needs no other connections. If this thing doesn't last, the next replacement will be a higher quality pump with a standalone neutralizer. Thank you again for the help on this....See Moredeweymn
