    Cool evap coil 1/2 ton larger then condenser?

    Word has it in my shop that upsizing the evap coil will give you maximum dehumidification.

    I am a commercial service tech, I am not a res. installer so.....


    Question for you is: a 3 ton evap coil with txv going to work with a 2.5 ton 13 seer condenser?

    I spoke to the mfg. and they said you dont need a txv with a 13 seer only the 14 seer. I thought all 13 seers required txv for maximum eff. ???

    Now I am asking this question looking for real answers so for those of you who enjoy bashing people (you know who you are) please keep your comments to yourself.

    Thanks..........

    Upsizing the evap coil sometimes lowers latent capacity (so it wouldn't give you maximum dehumidification--downsizing the coil would, but you'd have to make sure it's rated by the manufacturer), but it's done to get higher efficiencies in most cases (for residential). It may depend on the manufacturer. There are some ARI matchups with 1/2 ton or even 1 ton upsize on evap coil. Hope this helps.

    How many times must one fix something before it is fixed?

    Be nice to beenthere. He's got a lot of experience and a large wealth of knowledge regarding HVAC.

    Some, if not all manufacturers have performance data that provides the SHR and latent/sensible capacity of different coil matchups.

    In terms of there in the user handle beenthere. I thinks it's a safe assumption there = everywhere.

    Yo Beenthere - you're a WAD. keep your vile attitude to yourself, and don't waste the time of people who are really interested in learning by having to read YOUR attitude. like anyone is really going to take you seriously NOW.

    Not worried if anyone does or not.

    Definitely not worried about your opinion.

    She knows, or should know why I said that. And I'm the only one that showed her an example.

    Do yourself a favor and don't read it.

    proper air flow is most important for proper dehumification
