    Bryant vs Amana

    Both are good choices, but I always prefer to undersize a little then oversize.

    Robo - what do you mean?

    Besides, with an extended 10 year warranty the HO would pay nothing if a motor went up within 10 years and have the benefits of higher efficiency year round along with better filtration and dehumidification. Also, after 10 years of savings from a VS motor, a HO could have enough in savings to buy a new VS blower motor. It's a win-win situation.
    Wouldn't that depend on the static pressure.

    Isn't it true the high static VS fans use more watts then their PSC counterparts??

    Should have went with the Trane!! Just kidding Robo We have installed plenty of the ssx14's from Goodman, similar to the Amana without any problems. I think between the 2 I would go with the Amana but you need to base it on the contractor at this point. Definitely get the variable speed, well worth every penny.

    Workhc - why would you rather push the standard motor on a home someone is staying in. You don't like your customers to get a more comfy system with better efficiency?

    Be sure to get a thermostat , that will get all the benefits (venting, dehumidification.etc..)out of the designs of the systems.Your contractor should be able to explain all the options and benefits.....BTW, both systems are nice setups..

    If it is an all new install the duct should be designed and installed properly. But I do believe you are right, in high static situations they are or can be less efficient than a PSC motor.

    I have never seen anything to support this, or even heard it. I suppose it could be possible, but if your static is high enough to cause that kind of amp draw, it needs to be addressed. Also, if the static is that high, a psc motor would not be able to overcome the static enough to prevent air flow issues unless a larger HP psc motor were installed.....which is more expensive to operate.

    VS motors are not a substitution for repairing static pressure issues, but they do have advantages over psc motors under every adverse application.

    A-S publishes approximate wattage draws in their specs.

    100K 80% downflow 5 ton drive set for 1600ish and getting it

    .5" draw is 495 watts
    .9" draw is 595 watts

    but at max speed

    .5" draw is 800 watts but delivers 2015 CFM
    .9" draw is 725 watts but capability drops to 1740 CFM

    Manufacturers advertise,VS motor costs no more to run then a 40-60 watt light bulb .Well a small system at .2" ESP ,is the only way to get close.

    You need to look closely at the operating cost of VS at higher static,of course not so high that the don't deliver the required air flow,or cause other issues.

    Higher static with VS is part of why the don't run at the SEER or EER rating.

I'm trying to get an idea about reliability, efficiency, etc. I've read a lot of the posts here and know that most of the quality of a system is in the installer, but I'm trying to get an idea of the quality of the equipment. Also, any suggestions would be welcome as well. I'm in the Northeast, and the heating is a separate gas baseboard system. The house is a ranch, the c/a will be used for the main floor which is about 1600 sq ft.

    The systems quoted are:
    Bryant 3 ton 15 SEER model 165ANA036 R410-A with a Bryant FV4?003 a/h
    Amana 2 1/2 ton 14 SEER model ASX14030 with an Amana/Goodman AEPF3036 a/h

    Any thoughts are most appreciated. TIA
    The Bryant system is 35,000 btu cooling, 15.5 SEER, 13.5 EER.
    The Amana (Goodman) is 28,000 btu cooling, 15 SEER, 12 EER.

    Note that the Amana is ARI-rated with a thermostatic expansion valve in the air handler which is optional. The air handler comes with a piston flowrater metering device as standard issue.

    The 13.5 Energy Efficiency Ratio (EER) on the Bryant is outstanding.

    Good luck.

    Amana vs Bryant

    One other question since I'm woefully uneducated about this -
    • Complete duct system installed in the attic with main trunk line being galvanized sheet metal wrapped in an R-8 insulation with branch runs being insulated flex duct R-8 rated

    Is this normal, good, not-so-good?

    TIA

    Sounds pretty good to me from the brief description given.

    what is your natural gas rate/therm?

    what is your electric rate/kwh?

    how do you currently heat-a boiler?
