    Air handler for TRANE XR13

    What would be a good air handler match for TRANE XR13 4TTR3048A?
    The air handler will go into the cape cod style attic.
    I want to get an average priced unit.

    Thank you!

    It depends on what you're looking for--a standard blower or a variable-speed blower. The variable-speed blower is more efficient and can provide more humidity removal with Comfort-R enabled. You can also run the fan constantly at a low speed with the variable-speed blower.

    Standard blower:
    4TEC3F48B1000A - 13.00 SEER
    4TEC3F55B1000A - 13.25 SEER

    Variable-speed blower:
    4TEE3F49B1000A - 14.00 SEER

    What is your contractor proposing?

    he says variable speed is a waste of money unless condenser is a Two-Stage.

    I could not find 4TEC3F48B1000A, found 4TEC3F48A1000A instead. Does that make any difference?

    What would be the price difference between 2/4TEE3F49 and 4TEC3F48?

    Thank you.

    The "B" would just indicate a later revision of the air handler. We can't discuss pricing on this forum per site rules. Variable-speed isn't only for two-stage condensers. It can still provide advantages with single-stage condensers--more efficiency, better humidity control, more comfort, better airflow (in some cases)...

    Pricing differs from area to area and company to company. Your contractor's price difference may not be the same as other companies' price differences.

    I suggest getting a couple more estimates to compare prices in your area and to get more opinions. How was the system sized? A good system needs to be properly sized with proper ductwork. Is this a new installation or a replacement?

    This is a new installation. I had 5 contractors come by. They prices are so far apart that I am having hard time deciding. half of them recommend 4 ton unit, another half says 3 ton will do.

    Okay. Being a new installation, proper equipment and ductwork sizing is crucial. Which contractor, if any, did a load calculation (Manual J) and a Manual D to design the ductwork? Sometimes companies will do this once the contract is signed, but a good installation is the most important part. This is what I'd look for in a company, not a company that guesses on the size based on "years of experience." Sizing is determined by insulation, square footage, windows, home orientation/direction, etc...

    Unless your in a arid area, VS blowers improve comfort weather your condenser is single stage or 2 stage.
    Contractors that claim VS blowers are only for 2 stage systems. Generally don't know how to set a VS blower up right.

    If they are doing load calcs.
    You are gambling with your money and comfort.
