We're currently considering two contractors for our furnace and A/C replacement, although there are still some sizing issues to be addressed. Both appear to do a quality install, though neither is without drawbacks in other areas. One of the contractors uses Maytag equipment, the other uses Amana. I can find lots of Amana info, specs, install manuals, etc. on the Amana website and the internet. However, info on Maytag is much harder to come by (before you start thinking what you may be thinking, by no means do I consider this a DIY job! But I -do- like being able to look through the specs and manuals - it gives a real idea about what the equipment can do and how it works.)
I know Maytag is built by Nordyne, but that's about all I can find out about it. The maytaghvac.com site contains mostly propaganda, with no real details or technical specs on the equipment. The Nordyne site isn't much better, and of course doesn't include Maytag equipment anyway. Maytag seems more interested in selling me on the "brushed stainless steel doors/cabinet", etc. Who cares? I want to know how the equipment compares in build and features to the Amana AMV9 VS furnace and RCE 14 SEER A/C, the other system we're considering at the moment. We're looking at the PGF1T (M1010 2-stage variable speed) Maytag furnace, and the PSA1BD (M1010 13/14 SEER) A/C (I got the model #'s off the Maytag site - I assume they're correct). Probably would go with an Aprilaire 2200 for either system.
I've searched this site, and it appears that some of you really like Nordyne/Maytag and others don't much care for it. I'm always interested in opinions, but not interested in starting another brand war. So I tried to come up with a few simple questions:
1) I know the AMV9 has stainless steel tubular heat exchangers. What does the M1010 2-stage VS have?
2) The AMV9 has a nice blower ramping procedure for good dehumidification with A/C. dgk had previously posted that "the AMV9 already removes more moisture than standard furnaces because it has a variable speed motor, which operates at a lower fan speed (50% power for 30 seconds, then will ramp up to 82% speed and stay there for around 7.5 minutes, dehumidifying the air in the home. You are ... getting very good humidity removal." I thought I read somewhere that the Maytag VS furnace doesn't have anything comparable. Is this true?
3) Can the Maytag be used with the VP 8321 thermostat for additional humidity control (by slowing the VS blower), as well as taking full advantage of the two-stage furnace? Or is there a thermostat that you'd recommend over the 8321?
4) The AMV9 is supposedly 95.5%-96% efficient. The Maytag only claims 92%. Is there really this big a difference in the two, or is Maytag understating their efficiency? This could add up with gas prices climbing again.
5) Can anyone steer me to any real info on the Maytag equipment we're considering? I'd at least like to find info on BTU ranges available, high/low fire BTU in/out, real-world efficiency, physical build characteristics, etc.
I'm just trying to get a better idea how the Maytag equipment compares to Amana to see if that would sway our opinion to one contractor or the other. I assume both systems will perform well if installed properly, so I'm just wondering if there are any features that one system has that the other doesn't. That's what could make the difference in which contractor we go with. If both systems are essentially equal in features, that would be very helpful to know as well.
Thanks for your help!
